Do Australian building regulations promote safety, accessibility and livability of new dwellings?

A few months ago, I would have been astounded if someone told me that a building certifier in Australia could legally issue an occupation certificate with front path pedestrian access as shown in the photo above. In order to use the path, it was necessary for pedestrians to step over a concrete obstacle (14 cm on the driveway side and 23 cm on the house side). There was no way anyone could plausibly claim that the concrete obstacle was necessary for drainage, because water ran away from it toward the centre of the driveway.

With the benefit of hindsight, it is obvious that before buying a townhouse off the plan I had been lulled into a false sense of security by claims of building regulators that the Building Code of Australia (BCA) sets minimum standards for safety, health and amenity of buildings. I was not aware of the existence of the National Construction Code (NCC) at that time, but it wouldn’t have surprised me that it purports to provide “the minimum necessary requirements for safety and health; amenity and accessibility, and sustainability in design, construction, performance and livability of new buildings”.

I should have known better! I knew from the experience of many years working for governments that bureaucrats are no less prone to making extravagant claims than are people working in other occupations.

You might be thinking that even though it would be most unfortunate if someone was injured by tripping on the concrete obstacle, the existence of an occupation certificate, certifying that building regulation had been complied with, would protect the Owners Corporation against a compensation claim. That might be too sanguine a view. Legal information available from a reputable online source suggests that owners might not be fully covered by insurance if they could reasonably be expected to be aware of the issue and had not taken steps to address it.

The bigger issue of regulatory capture

In drawing attention to this pedestrian access issue, I am conscious that it is trivial by comparison with the building safety issues currently in the news associated with high-rise apartments in Sydney (Opal Tower and Mascot Towers). Michael Lambert, a former secretary of NSW Treasury, who reviewed building regulation for the New South Wales government and presented his report in 2015, has been quoted as saying that the issues associated with the Opal Tower “are likely just the tip of the iceberg”.

The Lambert report found “the incidence of building defects is significant” and “the incidence appears higher in NSW than elsewhere”. Lambert was not able to be more specific about incidence because “comprehensive information is not regularly collected on building defects”. He recommended that performance data be collected to enable the performance of the system to be assessed against clear objectives. In particular, he proposed a program of proactive investigations and audits of certifiers, linked to an education and training program for them. Lambert also recommended action to reduce the conflict between the accountability of certifiers for acting in the public interest and their commercial drivers for commercial success, including maintaining good relations with builders and owners/developers.

Michael Lambert has expressed disappointment that the recommendations of his report have not been more fully acted upon by the NSW government. It is not clear to what extent timely implementation of Lambert’s recommendations would have improved the quality of high-rise building in NSW, but the government’s failure to act more decisively on his proposals for incremental improvement seems to indicate that regulatory capture has become entrenched in this industry.

The theory of regulatory capture, advanced by the Nobel Prize winning economist, George Stigler, among others, refers to the tendency for regulatory systems created to act in the public interest, to instead advance the commercial or political concerns of special interest groups that dominate regulated industries. As it currently operates, the system of private certification seems to provide more protection to developers, builders, architects, engineers, and local government agencies that provide planning approval, than to home buyers.

Does more regulation provide the answer?

The knee jerk reaction of many people to quality control problems in the building industry is to urge that regulation be extended further and enforced more rigorously. However, even if determined political leaders can manage to steer some regulatory reform through the process of industry consultation, we need to face the reality that it would be prohibitively expensive for building regulation to be made much more than a ‘box ticking exercise’. Regulators can certify that certain things have been done, but that doesn’t ensure effective quality control. For example, regulators can certify that concrete has been poured to construct foundations, but it takes the resources of a building firm to control the quality of the concrete that is poured.

The main commercial incentives for firms to maintain effective quality control are to enhance their reputation in the market and to avoid litigation. Reform-minded political leaders should be seeking to identify how those market and legal incentives are impaired, and what corrective action could be taken.

Some readers might still be thinking that additional box ticking regulation would be an appropriate response to the specific question of safe residential access. I am wary of that approach because it could end up adding excessively to building costs and make homes less affordable.

Consider, for example, the guideline for dwelling access proposed by Livable Housing Australia:

“A safe continuous and step free path of travel from the street entrance and / or parking area to a dwelling entrance that is level.”

Complying with that condition would not have added much to the construction cost of our new townhouse, but in many instances a step free path would impose excessive costs. In a paper written over a decade ago, Alan Moran, pointed to evidence from government housing authorities - which commission a considerable part of the housing that is specifically geared towards the needs of people with disabilities - that the costs of the building are increased by at least 4% and up to 20% where houses are built fully compliant with the relevant Australian Standard.

The issue of liability

There are two overlapping aspects relating to the issue of liability for safe pedestrian access to residences. The first aspect is liability for compensation in the event of personal injury. My understanding is that the law sensibly provides liability on all parties involved to exercise reasonable care. I don’t know whether courts have held that developers and builders maintain some liability after residences have been sold. It would be a travesty, in my view, if they are able to hide behind an occupation certificate, when that does not certify that minimal safety standards have been met for pedestrian access.

The second issue of liability relates to the question of who should be liable for ensuring that reasonable expectations of home buyers are met in relation to safe pedestrian access. In thinking about this I have gone back to a paper written many years ago by Ted Sieper, an astute Australian economist who has been under-recognized because he eschewed academic norms to publish or perish. (Ted’s paper was entitled: Consumer protection – boon or bane?  It was presented to a C.I.S. conference held at Macquarie University in April 1978.) Ted argued that in considering the choice between the alternatives, caveat emptor – let the buyer beware – and caveat venditor – let the seller beware – law makers should compare the relative transactions costs that would be imposed on buyers and sellers. He noted: 

“while consumers with different safety requirements can discriminate cheaply among different products, producers can only with great difficulty discriminate among consumers”. 

(I am grateful to Greg Cutbush for suggesting that I look for Ted’s paper.)

I think Ted’s transactions cost point is highly relevant to the issue of safe pedestrian access. It seems reasonable to expect that that developers and builders would generally show some care to avoid compensation claims for personal injury. However, it is up to individual home buyers to shop around to obtain the standard of access safety they require.

With the benefit of hindsight, we should have insisted that an appropriate standard for safe residential access was written into the contract of sale before we agreed to buy. If the developer had been reluctant to agree to that provision, that would have set alarm bells ringing in our minds.

Regulators should stop making misleading claims!

There is irony in the fact that regulation to protect consumers aims to discourage misleading claims by vendors, but apparently does nothing to discourage building regulators from making misleading claims about the products they are selling.

Regulatory authorities should be required to renounce misleading claims they have made that the BCA and NCC provide minimum necessary standards for safety.  

If building regulators want to be helpful to home buyers, they should advise them to consult their lawyers to ensure that contracts for sale require developers to meet appropriate standards for safety and amenity.   

Where did I go wrong in writing about the greatest threat to human flourishing?

Chapter 8 of my book Free to Flourish, published in 2012, is entitled “The Greatest Threat to Progress”.

The concluding paragraph of that chapter now seems like an exercise in wishful thinking:

“There is an urgent need for innovations to promote a better balance between the responsibilities and effectiveness of government. The best hope is that, as more people perceive the threats that democracy is facing, they will unite to foster the development of better norms of political behaviour."

Do you perceive that a growing proportion of voters in your nation are using politics opportunistically to obtain benefits for themselves at the expense of others? If so, do you perceive that such behaviour is a threat to the democratic political system? Are you willing to commit to promoting mutual benefits for all citizens in your participation in political discussions and in casting your vote?

If you answered “yes” to all those questions, how much time and energy are you prepared to invest in encouraging others to unite with you in fostering restoration of better norms of political behaviour?

I still think it is commendable for individuals to foster better norms of political behaviour, for example in their activities on social media. However, the idea that citizens might unite to restore better norms of political behaviour now seems excessively optimistic.

Where did I go wrong?

I haven’t changed my view that the failure of democratic governments to cope with their expanding responsibilities is the greatest threat to human progress – the ongoing expansion of opportunities for human flourishing - in coming decades. Democratic failure seems likely to be particularly traumatic for people who have become heavily dependent on government.

My analysis in Chapter 8 of what determines whether democracies can cope still looks sound. The democratic governments that are highly effective in raising revenue and managing provision of services with little corruption (e.g. Sweden) are able to cope with greater responsibilities than can governments that are less effective in performing those functions (e.g. Greece). The ability of democratic governments to cope depends on the balance between responsibilities and effectiveness.

It still seems correct to argue that there is an inherent tendency in democracies for the size of government to expand and for the effectiveness of government to falter. That is a natural consequence of unrestrained politicking by interest groups.

I still think Joseph Schumpeter and Bryan Caplan were correct to argue that citizens are prone to irrational prejudice in political matters. My empirical work helps illustrate the nature of the problem. It shows that the percentage people who seek an expanded role for government is higher among citizens who claim to have little confidence in the civil service and no interest in politics.

My argument that democracy has survived because it has been constrained by constitutions, rule of law and federal systems of government still looks ok. If writing the chapter now I would also emphasise that norms of reciprocity have helped to restrain interest group opportunism in the past.

I think my discussion of changes in democracy brought about by increased citizen involvement through talk shows, social media etc reached the correct conclusion. The changing political environment seems to have provided greater incentives for political parties to become involved in identity politics, and to seen to be doing more to deal with all the problems of modern life:

"The realm of personal responsibility has shrunk as more personal problems have become transformed into social problems. The net result in most high income countries has been an aggravation of the tendency for governments to take on more responsibilities than they can cope with effectively. Yet governments are constantly pressured and tempted to accept additional responsibilities."

That quote from Free to Flourish is followed immediately by the heading: “A basis for hope”. That is the section in which I made a valiant attempt to persuade myself that citizens might unite to foster the development of better norms of political behaviour.

There was nothing wrong with looking for a basis for hope. In retrospect, I was just looking in the wrong place.

Developments over the last few years suggest that there is a basis for hope in two different directions.

First, it looks to me as though the consequences of democratic failure might not be quite as dire as I had envisaged in 2012. At that time it seemed to me as though democratic institutions were coming under threat in some countries of southern Europe because of increased public disorder associated with government debt crises and resistance to government spending restraint. I was concerned about democratic governments being replaced by authoritarian regimes, as has occurred under similar in the past in Europe and Latin America.

What has happened is that democratically elected leaders have remained in place to administer the austerity that was imposed by the European Central Bank. The failure of democratically elected governments to control government spending resulted in external imposition of constraints on fiscal policy. This has been accompanied by a great deal of economic misery in the countries affected, but outcomes have been better than I had expected.  

As discussed in a recent post, I expect that in most OECD countries the failure of democratic governments to restrain the growth of government spending is likely to cause debt servicing to become a more widespread problem in the decades ahead. Perhaps there are grounds for hope that when they see the writing on the wall, a sufficient proportion of voters in most wealthy countries will be supportive of political parties proposing economic reforms, rather than waiting until they are imposed by creditors (or institutions such as the ECB and IMF).

Second, there is now a stronger basis for hope that the faltering institutions of representative government could one day be replaced by superior institutions. I was sceptical about that possibility at the time of writing Free to Flourish. Since then, however, it has become evident that blockchain technology and smart contracts may have potential to enable people to act together to produce some public goods cooperatively without central government involvement. I became enthusiastic about the potential for that to occur a few months ago when reading The Social Singularity, by Max Borders.  I have learned a little more about blockchain and smart contracts since then, and am still enthusiastic about the potential it offers.

A transition from government to cooperative provision of services cannot be expected to prevent the human misery likely to occur as a result of failure to constrain government spending before debt servicing problems become acute. Over the longer term, however, it may become possible for people to enter voluntarily into real social contracts that offer better opportunities for human flourishing than the hypothetical social contracts of political theory.

Perhaps it would have been better for Chapter 8 of Free to Flourish to have concluded by focusing on ways in which individuals might be able to protect themselves and their families from the consequences of democratic failure.

The most obvious way for people to protect themselves and their families is to avoid becoming heavily dependent on government. I acknowledge that for many people that is easier said than done. Few people choose to become heavily dependent on government. Hopefully, safety nets will continue to be available for those who need them most.  Nevertheless, self-reliance and voluntary cooperation for mutual benefit will provide most individuals the best hope for economic security in the years ahead.

Which of the western democracies will be able to cope with future growth in government health spending?

The chart shows that those OECD countries with the greatest burden of debt servicing a decade ago have subsequently had the lowest growth in government spending. It isn’t hard to understand how that might happen when we think about the consequences of accumulating debt in our personal lives. If we go heavily into debt, a higher proportion of our income must be devoted to servicing debt and less is available for other spending. Our creditors are likely to be reluctant to extend further credit if they become concerned about our ability to service existing debt.

At a national level, there are additional complications including the potential for governments to inflate away the real value of debt denominated in local currency and possible ‘bailouts’ by the IMF and ECU. Nevertheless, governments that become poor credit risks must pay a higher risk premium than is normal for government bonds, in order to obtain access to additional credit.

There is evidence that rising government debt to GDP ratios are associated with lower economic growth, which in turn, leads to lower growth in government revenue. That obviously has potential to further squeeze non-interest government spending. The results of a recent study published by the Dallas Fed (‘Rising Public Debt to GDP Can Harm Economic Growth’, by Alexander Chudik, Kamiar Mohaddes, M. Hashem Pesaran and Mehdi Raissi) suggest that over the longer term persistent accumulation in debt as a percentage of GDP at an annual rate of 3 percent is eventually associated with annual GDP growth outcomes that are 0.2 to 0.3 percentage points lower on average. To put that in perspective, the average growth rate of OECD countries has been about 1.5 percent per annum over the last decade. Causality could run both ways. Lower GDP growth can lead to higher debt levels, which, in turn, can lead to lower economic growth.

You might be wondering why I think the chart shown above has much relevance for western democracies other than Greece, Italy and Portugal, which had high government debt servicing burdens a decade ago. The relevance stems partly from the continued increase in government debt as a percentage of GDP in most OECD countries over the last decade. On average, net financial liabilities of those countries have risen by around 23 percentage points of GDP over the last decade to around 67% of GDP in 2018.

Those looking for reasons to be complacent can obtain some reassurance from low world interest rates. With interest rates paid by governments lower than the rate of economic growth in most OECD countries, debt servicing is not yet a widespread problem. At current interest rates, it would be possible for the debt to GDP ratio to decline in most OECD countries, even if governments pay interest on their debts by borrowing additional funds.

How likely is it that world interest rates will remain at low levels over the next few decades? In their recent OECD paper, The Long View: Scenarios for the World Economy to 2060, Yvan Guillemette and David Turner suggest that relatively low growth in investment is likely to keep downward pressure on world interest rates, even though population ageing is likely to reduce savings rates. Nevertheless, they note evidence that reversals of the relationship between world interest rates and economic growth rates have been “fairly common” in the past. They warn that a sustained rise in interest rates relative to growth “could eventually make large debt stocks costly to service and unsustainable”.  Their projections suggest that some decline in economic growth rates is likely to occur in most parts of the world over the next 40 years.

My concerns about the potential for debt stocks to become costly to service in many more OECD countries are related to the implications for government spending of the ongoing increase in the proportion of elderly people in the populations of these countries. The implications of demographic change have been much talked about over the last few years, but the magnitude of the likely impact on government spending doesn’t yet seem to be widely appreciated. The study by Guillemette and Turner projects an increase in annual public health and pension spending of about 5 percentage points of GDP for the median OECD country between 2018 and 2060. The bulk of that increase is for public health spending, which is projected to continue to be pushed up by technological change and government health policies, as well as demographic factors.

The methodology used by Guillemette and Turner produces estimates of the increase in the revenue to GDP ratio needed to pay for projected government spending increases without any further increase in debt to GDP ratios. An increase in revenue as a percentage of GDP of 6.5 percentage points of GDP is projected to be required for the median OECD country over the period to 2060. A much larger increase is projected to be required in some countries. For example, the required increase in revenue for the U.S. is projected to be 10 percentage points of GDP.

I think the baseline scenario presented by Guillemette and Turner is too optimistic because their modelling takes no account of the disincentive effects of higher taxation on GDP growth. The possible magnitude of this excess burden of taxation is discussed in an Australian context in an article posted on this blog a few years ago.

Leaving that aside, it seems to me that ongoing increases in debt to GDP ratios - and hence substantial increases in government interest payments as a percentage of GDP - are a much more likely outcome in most OECD countries than tax increases in the years ahead. In those countries where debt servicing isn’t yet a problem, there seems likely to be much less political opposition to further increases in public debt than to tax increases. That suggests to me that over the next few decades most OECD countries are likely to increase their debt to GDP ratios until debt servicing does become a more widespread problem.

Guillemette and Turner present scenarios that would require smaller increases in government revenues than in the baseline (no-change) policy scenario, but those scenarios involve health policy and labour market reforms that have been difficult to achieve in the past. I don’t think we can expect voters to be any more supportive of reforms that could damage their short-term interests than they have been in the past. The best we can hope for is that when they see the writing on the wall, a sufficient proportion of voters in most countries will be supportive of political parties proposing economic reforms, rather than waiting until they are imposed by creditors (or institutions such as the ECB and IMF). In 2013 I wrote something here contrasting the responses of Sweden and Greece to fiscal crises, that illustrates the choices available.

The transition may be traumatic, but it seems likely that technological advances will provide options superior to government provision of many services in coming decades. What I have in mind particularly is the potential for blockchain to enhance opportunities to seek mutual benefit in voluntary cooperative enterprises, as previously discussed on this blog. That may create potential for functions to be transferred from the public sector to cooperative enterprises that can perform the functions more efficiently.

During the next few decades most of the western democracies seem likely to experience ongoing difficulty in coping with the additional government spending required to meet the health needs of the elderly.  The most likely outcome seems to me to be an increase in debt to GDP ratios that will result in more widespread debt servicing problems. It seems inevitable that debt servicing problems will lead to a lower rate of growth in government spending in many OECD countries, possibly accompanied by the transfer of some functions to voluntary cooperative enterprises.

That leaves the difficult question of identifying which of the western democracies are more likely to be able to implement those reforms through normal democratic processes in order to avoid having austerity imposed upon them by creditors and international agencies.

Can the hope circuit help us to circumvent dysfunctional politics?

This question came to mind when I was reading the final chapter of Martin Seligman’s latest book, The Hope Circuit.

The book is an autobiography, but in discussing his own life the author provides readers who have little knowledge of psychology, people like me, with a painless way of informing themselves about some major developments in this field over the last century.

Marty Seligman played an important role - as a researcher, author of popular books, and transformational leader - in helping to bring about important changes in his profession. He made major contributions in encouraging the profession to study cognition, recognise evolution, embrace positive psychology, and give greater attention to prospection.

I will focus here on learned helplessness, learned optimism and the hope circuit. Marty, as he is accustomed to being called by just about everyone, made his name as a researcher in the 1960s for his work, with Steve Maier, on learned helplessness. Marty and Steve observed that when dogs were unable to avoid electric shocks by changing their behaviour, they subsequently tended to remain passive when they did have the opportunity to avoid shocks. The dogs appeared to have learned that nothing they did mattered.

Marty saw the potential implications of this research for understanding of mental illness among humans and developed the helplessness theory of depression on that basis. That theory was subsequently reformulated, with assistance from John Teasdale, to take account of the way people think about the causes of their feelings of helplessness. For example, those who see their current problems as likely to last forever and to undermine everything they do are likely to feel helpless long into the future. Pessimism leads to helplessness.

Marty’s popular book, Learned Optimism, published in 1990, integrated research findings on learned helplessness and explanatory style.  It advocated disputing pessimistic thoughts as the central skill of learned optimism.

Marty coined the term “hope circuit” in 2015 to describe the MPFC-DRN circuit of brain activity discovered by Steve Maier, who had retrained as a neuroscientist. Marty explains that Steve’s discoveries turned learned helplessness on its head:

“He showed that the arrow of causality that we had postulated was wrong and that it was not helplessness but control and mastery that were learned".

One of the implications of this research is that therapy that “creates end runs” around trauma and helps people to plan a better future is likely to be more helpful than therapy that tries to undo trauma by confronting the past.

What does all this have to do with dysfunctional politics? This passage got me wondering:

"Human history has, until recently, been a tale of woe: warfare, plague, famine, injustice, poverty, ignorance, and violent death. The last half century has witnessed, if not the eradication, a great reduction of these ills. When the world is a vale of tears, it is natural that politics, religion, science, medicine, and the arts should concern themselves with defense and damage. But what happens when the world is no longer a vale of tears?"

My initial reaction to that passage was the same as my reaction to Steven Pinker’s book, Enlightenment Now. I agree that massive progress has been made in human flourishing, but I see huge problems ahead for liberal democracy. We are confronted by widespread failure to adhere to the norms of self-reliance and reciprocity that underpin liberal democracy.

I became even more pessimistic when my thoughts turned to Jason Brennan’s book, Against Democracy. In my response to that book I mourned the declining power of the major political parties to shape political agendas in ways that moderate the ill-informed desires of electors. I raised the question of whether many voters would be likely to accept impartial advice on how to vote to achieve their objectives.

It is not obvious that there is anything that anyone can do now to save liberal democracy from political hooliganism.

So, why aren’t I feeling depressed and helpless?  The main reason is that a few months ago Max Borders’ book, The Social Singularity, gave me grounds to hope that technological advances will eventually enable citizens to circumvent dysfunctional politics. Rather than moaning endlessly about the decline of liberal democracy, we can look forward in the hope of a better future. There may even be practical things that we can do in cooperation with others to facilitate growth in opportunities for human flourishing.   

Why don't all sides of politics agree to pursue Wealth Plus?

It would be great if the major political parties in all countries of the world were to pursue Wealth Plus as a national objective. However, I don’t think that is likely to happen soon, even in the wealthy countries that have implicitly pursued similar objectives in the past.

Wealth Plus is the objective advocated by Tyler Cowan, in his recently published book, Stubborn Attachments: A vision for a society of free, prosperous, and responsible individuals. Tyler defines Wealth Plus as:

‘The total amount of value produced over a certain time period. This includes the traditional measures of economic value found in GDP statistics, but also includes measures of leisure time, household production, and environmental amenities, as summed up in a relevant measure of wealth."

Tyler also suggests that we should aim to “maximize the rate of sustainable economic growth, defined in terms of a concept such as Wealth Plus”. He suggests that we should think more broadly about economic growth as an ongoing self-sustaining process that produces goods that contribute to human welfare, rather than in terms of growth in GDP as conventionally measured.

I think the objective that Tyler is writing about could better be described in terms of pursuing growth in opportunities for human flourishing – growing opportunities for people to live the lives that they aspire to have. I prefer that terminology partly because it fits neatly with the view I expressed in Free to Flourish that good societies are characterised by widespread opportunities for human flourishing. In my view, progress is movement toward better societies, with growing opportunities for human flourishing.

An emphasis on human flourishing raises a question, touched on in an appendix, of why human flourishing should be prioritized above the flourishing of non-human lives. One good reason is that flourishing humans show greater consideration for non-human lives than do humans who are struggling to survive. Discussion about what constitutes ethical behaviour toward non-human lives is a feature of modern life in prosperous countries. More fundamentally, if ethical behaviour is intrinsic to human flourishing – as Aristotle argued persuasively long before modern psychologists took up the idea - then human flourishing must encompass ethical behaviour toward all other living creatures.

Tyler makes a strong case that we should care about the well-being of people in the distant future just about as much as we care about the well-being of the current generation. His argument is based partly around the implications of discounting the value of future human lives. Under any positive discount rate, one life today could appear to be worth as much as the entire subsequent survival of humanity if we use a long enough time horizon for the calculation.

The argument for using a low discount rate seems to me to have considerable force when we are considering the benefits of public investments to protect future generations from potential catastrophes. As previously discussed on this blog, that argument is pertinent in considering what discount rates should be used for public investments to avert or mitigate climate change risks.

I am not persuaded by Tyler’s argument that the well-being of future generations isn’t adequately considered today in the choices “we” are making about “how rapidly to boost future wealth”. The “we” Tyler is referring to is the collective “we” that makes public policy choices. As I have previously suggested, the argument that positive externalities cause free markets to produce too little economic growth does not appear to have any more merit than the argument that negative externalities cause free markets to produce too much economic growth. Tyler hasn’t persuaded me that government intervention can improve on the growth outcomes of the savings and investment decisions made by individuals and families in a free market.  

In any case, the choices that governments make about “how rapidly to boost future growth” seem to be largely implicit rather than explicit. Boosting economic growth may be a motive for public investment in research and some forms of education, but I can’t think of many other examples. Perhaps what Tyler has in mind are the choices that governments make that unintentionally reduce the rate of economic growth. For example, he notes that when government spending is cut, investment spending is often the first area to go while entitlements for the elderly remain intact.

Tyler is on firm ground in arguing that the strengthening of good institutions today can be expected to provide benefits for centuries into the future. There is strong historical support for the view that growth promoting institutions and a history of prosperity tend to have enduring effects.

Tyler suggests that three key questions should be elevated in their political and philosophical importance, namely:

1.       What can we do to boost the rate of economic growth?

2.       What can we do to make our civilization more stable?

3.       How should we deal with environmental problems?

He goes on to observe:

“The first of these is commonly considered a right-wing or libertarian concern, the second a conservative preoccupation, and the third, especially in the United States, is most commonly associated with left-wing perspectives. Yet these questions should be central, rather than peripheral, to every political body. We can see right away how the political spectrum must be reshaped to adequately address these concerns. Politics should be about finding the best means to achieve these ends, rather than disputing the importance of these ends."

I agree that is what politics should about, but I am not optimistic that political leaders can pursue those ends diligently, even if they can be persuaded to embrace them. Liberal democracy has been weakened in recent decades by widespread failure to adhere to the norms of self-reliance and reciprocity that underpin it. As predicted by James Buchanan (see this post for explanation) failure of the liberal democracy is becoming increasingly likely as a higher proportion of the population becomes dependent on government, and voters increasingly seek to use the political process to obtain benefits at the expense of others.  

It is difficult to escape the conclusion that we are heading toward a tragedy of democracy. When interest groups view the coercive power of the state as a common pool resource to be used for the benefits of their members, the adverse impact of tax and regulation on incentives for productive activity produce outcomes that a detrimental to just about everyone. The process seems to be intensifying with the fragmentation of broad interest groups supporting the centre left and centre right of politics.

As Henry Ergas has noted recently, with particular reference to Australia, it has become “increasingly difficult for “catch-all” parties — as both our main parties have been — to position themselves in such a way as to aggregate a winning coalition. The concept of the ‘average’ or ‘median’ voter, which used to help orient the parties’ choices, has lost its substance, as has the notion of ‘the centre’. (“The Australian”, 25 Oct. 2018).

Similar problems are evident in other mature democracies. The process of fragmentation of broad interest groups has accelerated in many countries over the last decade or so as innovations in the social media have greatly increased the power of the rabid sports fans of politics - aptly referred to by Jason Brennan as Hooligans. Hooligans tend to seek out information that confirms their pre-existing political opinions and ignore or reject information that contradicts those opinions. They tend to communicate in echo chambers that reinforce their outrage when the leadership of the major parties is unresponsive to their concerns.

In some countries we are seeing ill-informed Hooligans taking over major parties and the reins of government. In other countries splinter parties comprised of Hooligans are attracting supporters away from major parties and making it more difficult for them to pursue coherent policy agendas. No matter which way it is happening, the growing political influence of the Hooligans makes it increasingly difficult for political leaders to pursue Wealth Plus, or any goals relating to the future well-being of the broader communities who elect them.

As more people come to recognize that liberal democracy is confronted by deep problems, perhaps some of them will attempt to make concerted efforts to reform political institutions so that they produce better outcomes. However, it is not obvious what reforms would stop the rot or how reforms could be achieved. A major economic crisis might help to focus the minds of responsible political leaders, but it could just as easily further strengthen the hands of the Hooligans.

I now think the best hope for future generations lies in the potential for new technology to enable people to circumvent the obstacles created by the Hooligans of national politics. As Max Borders has suggested (see discussion on this blog here and here) technological innovations provide us with the potential to “reweave the latticework of human interaction to create a great reconciliation between private interest and community good". The social singularity has potential to enable people to enjoy growing opportunities to live the lives that they aspire to have.

Should we look forward to the Social Singularity?

The social singularity should not be confused with the technological singularity, which Wikipedia defines as the hypothesis that invention of artificial superintelligence will abruptly trigger runaway technological growth, resulting in unfathomable change to human civilization.

The Social Singularity, as described by Max Borders in his recently published book of that name, relates to the way we (humans) organise ourselves in relation to each other. Max’s hypothesis is that at some point social organisation will be completely transformed as a result of mass adoption of secure networking technologies. When that happens some existing mediating structures will become obsolete, new forms of coordination will emerge and we will collaborate as never before.

What does that mean in terms that you and I can understand? The best place to begin is with the concept of subversive innovation. You might think it is tedious to begin an explanation by introducing another concept, but I promise to provide some concrete examples before long.

These days just about everyone knows what an innovation is. Most readers will be familiar with disruptive innovations that are making many goods more accessible and affordable. Subversive innovations “are those that have the potential to replace long-accepted mediating structures of society”. The mediating structures that Max is writing about include: hierarchical firms; group-think practices among the scientific establishment that have led to widespread acceptance of numerous findings that cannot be replicated; centralised education which views students as having “heads like buckets to be filled with information curated by central elites”; long-standing practices of financial intermediaries; mainstream media that once generated social coherence; and national governments.

Readers will already be familiar with some of the subversive innovations that are occurring. Some firms are replacing hierarchical command and control structures with decentralised systems in which self-directed individuals create order by establishing networks to achieve common purposes. The Internet has enabled informal networks of people, often including amateurs, who question scientific dogma e.g. the paleo-diet movement. Disruptive innovation has begun in primary, secondary and tertiary education. Long-established practices of financial institutions are being challenged by block chain technologies, and cryptocurrencies are enabling people to transact without using national currencies or financial intermediaries. The Internet has disrupted the role of mainstream media in generating social coherence - making it possible for populists to challenge political orthodoxy, but also reducing the potential for views to coalesce around a deeply flawed narrative.

The potential for subversive innovations to displace centralised government is in my view the most interesting idea in the book. We can already see this happening to some extent as innovating firms search out the weak joints in government regulation, particularly the regulatory barriers to competition that have enabled incumbents in various industries to prosper at the expense of the rest of the community. Think of how Uber’s ridesharing innovations circumvented regulations protecting incumbents in the taxi industry.

Max suggests that the potential for subversive innovations to displace centralised government will be enhanced by the advent of smart contracts in which a host of humans can act together to achieve a common goal without middlemen. The coordinating mechanism of smart contracts involves distributed ledgers, programmable incentives and blockchain secured tokens. Tokens can align the interests of producers, consumers and investors in ways that may have potential to enable many types of public goods to be produced privately by profit-seeking entrepreneurs. It doesn’t seem possible at this stage to provide a concrete example of how this might work. Perhaps it can be thought of as crowdsourcing on steroids.

Where might this take us? Max suggests that the potential for people to forge real social contracts - contracts they choose to enter voluntarily rather than the hypothetical social contracts of political theory - “could become the killer app of politics”:

"Communities of tomorrow will form entire systems of mutual aid through digital compacts that have nothing to do with borders or accidents of birth. … Humanity will upload important commitments into social contracts. Cosmopolitan communities of practice will form in the electronic ether. What remains on the ground—goods, services, and the relationships of flesh-and-blood neighbors—will be a far more localized phenomenon. The days of outsourcing our civic responsibilities to distant capitals are numbered."

What Max has in mind is polyarchy – competitive provision of goods that have been provided collectively. The basic idea is that if there is nothing intrinsically territorial about a system that provides goods like health insurance or education, you should be allowed to exit one system and join another without moving to a different system’s territory. You could take resources you were once required to pay in taxation and use them to pay for membership of another community or multiple other communities.

So, what reason do we have to think that governments might one day be willing to recognize the right of exit required to make polyarchy a reality?

Max notes that new constituencies are forming around the benefits of the sharing economy:

"Special interests that once squeaked to get the oil are confronted by battalions bearing smartphones. Citizens, fed up with leaving their prayers in the voting booth, are voting more with their dollars and their devices. Free association is now ensured by design, not by statute."

The Social Singularity mixes the author’s views on how things ought to evolve and how he expects them to evolve. Max acknowledges that he does this. The book offers readers an appealing vision of how the future could evolve and invites them to help make that vision a reality.

The book contains much that I haven’t written about in this short review. I should mention the link between the social singularity and spiral dynamics. Now I have mentioned it, I want to write more about it. Perhaps later!

I should also note before concluding that the title of the book, as presented on the title page, is The Social Singularity: A Decentralist Manifesto. Decentralization is a theme of the book. Max begins his chapter on the future of governance by quoting Vincent Ostrom:

“The fashioning of a truly free world depends on building fundamental infrastructures that enable different peoples to become self-governing”.

 In a post I wrote a few months ago I mused about how Ostrom’s vision of decentralisation of politics could eventually become a reality. If I ever write on that topic again there will be a reference to Max Borders and the concept of subversive innovations will feature prominently.

The Social Singularity deserves to be read widely and thought about deeply.

Is Steven Pinker too optimistic about the future of liberal democracy?

Steven Pinker’s aim in Enlightenment Now, The case for Reason, Science, Humanism and Progress, is “to restate the ideals of the Enlightenment in the language and concepts of the 21^st century” and to show that those ideals have worked to enhance human flourishing.

In response to one of Pinker’s earlier books I was prompted to consider whether Enlightenment humanism is the coherent world view that he claims it to be. In this book Pinker makes clear that he views “the ideals of the Enlightenment” to be synonymous with the open society and classical liberalism.  He argues that four themes tie the ideas of the Enlightenment together: an insistence on applying reason to understand our world; use of the methods of science; humanism, defined in terms of a focus on the happiness of individuals rather than the glory of tribes, races, nations or religions; and the hope for progress through political institutions that are conducive to human flourishing. Pinker regards liberal democracy as “an Enlightenment-inspired institution” and “a precious achievement”.

In my view Pinker succeeds admirably in showing that for the last two and a half centuries application of those Enlightenment ideals has enhanced individual human flourishing. Much of the book is devoted to evidence of the massive progress that has been made in the quality of life enjoyed by people on this planet over that period. I recommend this book and Max Roser’s Our World in Data web site (the source of much of Pinker’s data) to anyone who needs reminding that ‘the good old days’ were not so great.

Turning to the future, Pinker is more of a hopeful realist than an optimist. He recognises that “the darker sides of human nature – tribalism, authoritarianism and magical thinking – aided by the Second Law of Thermodynamics” have potential to push us back. In an early chapter he points out that in a world governed by entropy and evolution, the default state of humankind is characterized by disease, poverty and violence. A large and growing proportion of humanity have been able to escape from the default state through ongoing adherence to the norms and institutions fostered by the Enlightenment.

As I see it, the prospects for further progress in human flourishing in the liberal democracies will be strongly influenced the effectiveness of this form of government in delivering economic policies conducive to ongoing productivity growth. Productivity growth will obviously be required if people continue to aspire to have higher disposable incomes, but it will also be required to generate the additional taxation revenue needed to prevent public debt spiralling out of control. That is because spending on social welfare programs – particularly health care and retirement benefits - is likely to rise as the proportion of elderly people rises. Resort to higher tax rates would be likely to have adverse effects on incentives to work, save and invest, and thus reduce productivity growth.

Pinker notes that with stronger safety nets in place, the poverty rate for elderly people in the United States has plunged since the 1960s and is now below that for younger people. However, generous safety nets have a down-side. People in the liberal democracies face traumatic adjustments in the years ahead if governments are unable to meet public expectations of ongoing funding of existing programs at current levels.

Pinker recognizes low productivity growth and “authoritarian populism” as potential threats to human progress but does not draw out the links between these threats. Most of the populists that he is concerned about do not strike me as being particularly authoritarian, in the sense of enforcing strict obedience to authority. Nevertheless, they are stasists, seeking to undermine the Enlightenment values that have enabled technological progress and international trade to contribute massively to human flourishing since the beginning of the industrial revolution. Pinker’s discussion of the recent causes of low productivity growth is adequate, as far as it goes, but he fails to emphasize the potential for additional damage to be done by populist politicians seeking to capitalise on fears of the disruptive impacts of globalisation and technological progress.  

Pinker makes the important observation:

“A challenge for our era is how to foster an intellectual and political culture that is driven by reason rather than tribalism”.

He is scathing in his description of current electoral politics:

“Here the rules of the game are fiendishly designed to bring out the most irrational in people”.

In support of this assertion Pinker cites: the rational ignorance of voters; the bundling of disparate issues to appeal to a coalition of voters with geographic, racial, and ethnic constituencies; and media that “cover elections like horse races, and analyse issues by pitting ideological hacks against each other in screaming matches”. He notes:

“All these features steer people away from reasoned analysis and towards perfervid self-expression”.

Pinker’s suggests that for public discourse to become more rational, issues should be depoliticized as much as possible. His discussion of the ways in which issues become politicised and proposals for depoliticization of issues was covered in my last post on the benefits of listening to opposing viewpoints. His discussion ends by noting that the discovery of political tribalism as an “insidious form of irrationality” is “still fresh and largely unknown”. He appeals to readers:

“However long it takes, we must not let the existence of cognitive and emotional biases or the spasms of irrationality in the political arena to discourage us from the
Enlightenment ideal of relentlessly pursuing reason and truth”.

Pinker may not sound particularly optimistic about the future of liberal democracy, but he may well be too optimistic. Unfortunately, in addition to the irrationality he discusses, we are also confronted by widespread failure to adhere to the norms of self-reliance and reciprocity that underpin liberal democracy. As explained by James Buchanan (see this post for the reference) failure of the liberal order is becoming increasingly likely as a higher proportion of the population becomes dependent on government and voters increasingly seek to use the political process to obtain benefits at the expense of others.  

We seem to be heading toward what might be described as a democratic tragedy. As noted in an earlier post, when interest groups view the coercive power of the state as a common pool resource to be used for the benefits of their members, the adverse impact of tax and regulation on incentives for productive activity is likely to result in outcomes that will be detrimental for everyone. The incentives facing individual interest groups in that situation are similar to those facing users of common pool resources in the absence of norms of restraint.

Perhaps, as more people come to recognize that liberal democracy is confronted by deep problems, efforts will be made to reform political institutions to produce better outcomes. It is not obvious how that can be achieved, but we should not allow ignorance to prevent us from seeking solutions.

In my view Seven Pinker is on the right track in urging people to be hopeful:

“We will never have a perfect world, and it would be dangerous to seek one. But there is no limit to the betterments we can attain if we continue to apply knowledge to enhance human flourishing”.

What is to be gained by listening to opposing viewpoints?

It is comforting to listen to people espouse views like our own. Perhaps it makes us feel that our views are being validated.

Listening to an opposing viewpoint can feel challenging. There are several reasons for that. There may be times when we are not in the mood for the intellectual stimulation involved in considering the merits and demerits of an opposing viewpoint.

A more deep-seated reason for feeling challenged arises when we identify strongly with views that are being attacked. We may even feel offended. That has traditionally been seen to be likely when views on politics, religion and sex are being criticized. Ethnicity and culture should be added to that list. People also tend to be highly offended if anyone casts aspersions on the sporting teams they support.

However, taking offence is optional. Many Collingwood supporters, and many people of Irish and Scottish descent even seem to be able to see the humour in some of the jokes made at their expense.

From my childhood memories, in the farming community in which our family lived in the 1950s, there seemed to be greater willingness to listen to opposing political viewpoints than exists anywhere today. There seemed to be widespread acceptance that you need to listen to opposing political viewpoints if you want to argue against them effectively. People steered clear of discussion of religious differences and if anyone had views about sex and marriage that were at variance with conventional morality they didn’t discuss them openly.

The civility of the participants is obviously an important determinant of the amount of heat generated when contentious political issues are discussed. From my own experience, and limited discussions with others, I have the impression that in the 1950s people were generally more intent than they are now on maintaining civility when participating in political discussions. It seemed common for discussions to end in a meeting of minds on some points and respectful disagreement on others. Occasionally, when one of the main participants was intent on giving offence, discussions would end in an exchange of insults, or worse.

Have people become more open to listening to opposing views on other contentious issues since the 1950s?  A few years ago, I would have argued that the shibboleths had diminished as the major religions had become more tolerant of each other and a revolution in attitudes had caused many people to moderate their views of sexual morality.

It now seems that the old shibboleths have been replaced as new issues have become politicised. When issues become politicised it now seems to be much more common for people to parrot the views of the leaders of their political tribe and to refuse to consider opposing viewpoints. The art of listening seems to be disappearing from the public realm.

Steven Pinker has an interesting discussion of the politicization of issues in his recent book, Enlightenment Now: The case for reason, science, humanism and progress. He refers to research by the Dan Kahan, a legal scholar, who argues that bitter public disputes over science are now “the exception rather than the rule”. The exception arises when certain beliefs become symbols of cultural allegiance. To help make this point Kahan refers to recent U.S. history regarding vaccines for Hepatitis B and the HPV virus (a major cause of cervical cancer). Both vaccines prevent sexually transmitted diseases. Hep B vaccination has apparently been accepted without much opposition, but HPV vaccination has become a political firestorm because of fears that it would encourage teenage promiscuity. Kahan suggests that the difference stems from the way the two vaccines were introduced.  Hep B vaccination was treated as a routine public health matter, but the manufacturers of the HPV vaccine lobbied state legislatures to make vaccination of adolescent girls mandatory. Kahan’s view is supported by Australian experience of a voluntary HPV vaccination program being introduced successfully without the issue becoming politicised.

Issues often become politicized when they are taken up by political leaders. For example, it seems likely that by politicising the global warming debate, Al Gore’s documentary An Inconvenient Truth made it more difficult for conservatives to acknowledge the merits of any proposed policy action on climate change.

The media also plays a role in politicising issues by converting disagreement on public policy into a spectator sport.  In my view Australia’s public broadcaster, the ABC, is a major offender. The ABC’s charter requires it to inform and entertain, but unfortunately does not require it to encourage the reasoned debate and respectful disagreement necessary for liberal democracy to function effectively. In particular, the Q&A program seems to me to be designed to politicize policy debate. It entertains viewers by providing a forum for activist and conservative tribes to clash on totemic issues. Although some panellists and audience participants do their best to engage in reasoned debate, it would be difficult for any viewers to obtain a better understanding of alternative viewpoints from this program.

How can we have a useful exchange of views on issues that have become politicised? In a recent article on this blog I suggested that people who approach issues from different ideological perspectives would be able to have more useful policy discussions if they could turn their attention to what they can learn from the actual experiences of people in different institutional and policy settings. That is rarely straight forward, of course, because interpretation of experience is not immune to ideological bias. But it is still good advice!

It can also be useful to ask people to explain views you disagree with, rather than asserting that they are talking nonsense. Steven Pinker notes that when people are asked to explain an opinion they often realize that they don’t know what they are talking about and become more open to counter-arguments. That is more likely to occur when they are aware that someone is listening intently to the answer they are giving.

This view is consistent with Leah Goldrick’s conclusion in a recent article about the know-it-all syndrome. On her blog, Common Sense Ethics, Leah writes:

“Thinking is fundamentally driven by questions, not answers. This is why doubt, not certainty, is so important. Doubt is the starting place that leads us to question the assumptions that have lead us to a particular conclusion, and doubt is what drives us to learn more if we will humble ourselves enough to consider that we may be wrong. Constant learning, from a place of humble confidence, rather than a place of arrogance, is the antidote to know-it-all syndrome”.

You are more likely to have useful exchanges of view if you “assume that the person you are listening to might know something you don’t”. That is one of the rules that Jordan Peterson lists in his recent book, 12 Rules for Life (recently reviewed on this blog). Peterson suggests that we remain threatened by disease, self-deception, unhappiness and many other causes of suffering because we are too ignorant to protect ourselves. There is always potential for us to improve our own lives if we respect the personal experience of our conversational partners.

Some of my readers may be wondering whether there is any organisation they could joint to help cultivate a listening culture and improved communication in the community in which they live. A few weeks ago, the realisation dawned on me that for the past 16 years I have been a member of an organisation whose founder believed that “in bringing improvement in the way of better thinking, better listening, better speaking to individuals we are contributing to the improvement of the society which is made up of these individuals”. The quote is from an article by Ralph Smedley, founder of Toastmasters International, which appeared in the February 1958 issue of The Toastmaster. (The article, entitled, ‘The Toastmasters Club … Its Meaning and Values’, has been reproduced in Personally Speaking: Selections from the Writings of Dr Ralph C Smedley.)

The mission of Toastmasters is to develop communication and leadership skills of individual members so that they can achieve greater self-confidence and personal growth. The benefits that can bring to the lives of individual members are obvious but, as Ralph Smedley maintained, members of Toastmasters - now numbering more than 352,00 – also have an opportunity to contribute to “the building of a better society made up of individuals who must act in groups”.

Are nature and biodiversity essential to health and happiness?

There is no prize for guessing the answer given by Susan Prescott and Alan Logan in The Secret Life of your Microbiome: Why nature and biodiversity are essential to health and happiness.

This recently published book is written for a popular audience, but the authors have expert knowledge of the microbiome – the microbes and their genetic material found in the human gut and skin. Susan Prescott is an immunologist and paediatrician. Alan Logan’s background is in research relating to naturopathic medicine. It is obvious that the authors have spent a lot of time sifting through scientific evidence in writing the book.

Some of the evidence suggesting that nature and biodiversity are essential to health and happiness is derived from inspection of the stools of our Paleolithic ancestors. Evidence from archaeological sites suggests that our hunter and gatherer ancestors ate a wide variety of plant food and had a greater diversity of micro-biota than most people living modern lifestyles. The same is true today of people who are still living traditional lifestyles close to nature.

The authors accept that modern medicine and hygiene have brought great benefits, but they point to evidence that a diet with a great deal of sugar, ultra-processed food and drinks – as well as excessive use of antibiotics, stress and physical exhaustion – can lead to gut permeability, an increase in blood endotoxins, and an increase in central nervous system inflammatory chemicals. Intestinal permeability is apparently associated with a range of chronic conditions including autism, asthma, allergies, chronic fatigue, depression, fibromyalgia, heart disease, irritable bowel, obesity, type 2 diabetes, psoriasis and schizophrenia.

Prescott and Logan argue that we have a symbiotic relationship with the human microbiome, which co-evolved with our ancestors. The microbiome provides functional benefits such as nutrient extraction, protection against harmful microbes, regulation of metabolism and production of important biochemicals. Researchers don’t yet understand what microbes would comprise an ideal microbiome, but the key seems to be diversity, which is encouraged by dietary diversity. The authors suggest that the human immune system has evolved to expect a kaleidoscope of biodiversity.

The authors view commercially available probiotics and prebiotics as a useful supplement that can help defend against dysbiotic forces in the modern environment, rather than as a substitute for the adoption of a healthy lifestyle. They emphasize the importance of dietary choices, physical activity, sleep and experience of natural environments.

There is substantial evidence, some previously discussed on this blog, that experience of natural environments has a positive impact on health and happiness. Prescott and Logan provide an interesting account of Japanese research relating to shinrin-yoku – the absorption of the forest into the body and mind:

“Remarkable studies have demonstrated that, individually, the sounds of nature, the sights of nature, the invisible chemicals secreted from trees (phytoncides, or phytochemicals), and the touch of natural products like wood (compared to synthetic resin), can positively influence stress physiology and our parasympathetic nervous system, the “rest and digest” branch of the nervous system that cools the jets of over-stimulation. The sum of research shows that our sensory system understands nature like an old friend.”

One of the authors’ aims seems to be to promote nature relatedness – fascination with nature and a desire for contact with it. They note evidence that nature relatedness is associated with high levels of psychological wellbeing, lower anxiety and greater meaning and purpose in life. Experience in nature tends to lift nature relatedness scores. Practicing mindfulness while walking in nature has additional emotional benefits. Moreover, the combination of nature relatedness, mindfulness and meaningfulness of life promotes pro-environmental behaviours.

Prescott and Logan leave readers in no doubt that they view pro-environmental behaviours to be desirable. I agree with them.

However, I strongly disagree with authors about economics and politics. They argue:

“It’s up to governments, insulated against lobbyists, to help curb the wild west that is fueling the dysbiosphere. Time and time again industry has shown it just can’t stop itself from pushing dysbiotic choices on our children.”

They oppose the view that “an individual can assume responsibility for personal health problems by simply adopting what biomedicine has to offer”. They suggest that view is deficient because it “doesn’t consider that a broken socio-ecological system might be the driving force for the need of biomedicine in the first place”.

When I read such views I have to remind myself that in writing about supporters of socialism Friedrich Hayek insisted “that it is neither selfish interests nor evil intentions but mostly honest convictions and good intentions which determine the intellectual's views”. (Quote from ‘The Intellectuals and Socialism’). It is not necessarily a waste of time to try to correct the errors of well-intentioned people.

Some of the errors made by Prescott and Logan are as follows:

1.       The view that government can be insulated against lobbyists is contrary to everything that is known about government and human nature.

2.       The phrase “pushing dysbiotic choices on our children” refers to advertising and selling products that are only harmful to human health when consumed inappropriately. There is nothing in our legal or economic system that requires parents to buy such products for their children or to allow them to over-indulge. Firms already offer foods for sale that are beneficial to health and will have a greater incentive to do so as consumers become more aware of the health implications of the choices they make on behalf of their children.

3.       The widespread human misery (and environmental catastrophes) caused by socialist economic experiments during the 20^th century should make us wary of claims that the socio-ecological system is broken. In what respects is it broken? What precise interventions are proposed to fix it? And, are we sure, beyond reasonable doubt, that those interventions will produce better overall outcomes?

Susan Prescott and Alan Logan were unwise to include ill-informed rants on economics and politics in this book. It seems to me that those rants detract from their efforts to promote a revolution in attitudes toward the micro-biome and the environment.

In my view this book is nevertheless worth reading because of the substantial body of scientific evidence it provides that many aspects of human health and happiness depend on the microbiome.
