Why people can be much nicer than economists assume

There’s a lot you can learn about the world of work – and human nature in general – from studying economics. Then again, there’s a lot you can’t learn from conventional economics – and, indeed, from the bum steers it can give you.

Consider this. The 18th century Scottish philosopher Adam Smith is said to be the father of economics. He wrote two monumental books, the second of which, The Wealth of Nations, contained the famous observation that “it is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own self-interest”.

The worthies who developed conventional economics – and its “neo-classical” model of how markets work, the main thing taught in economics courses – seized on this idea to describe an economy populated by profit-maximising firms and self-interested consumers, all of them competing with each other to get the best deal.

They developed Smith’s reference to the “invisible hand” of competition in markets to show how this self-interest on all sides miraculously ends up satisfying everyone’s wants. Hence modern economists’ eternal banging on about the benefits of competition.

But Smith’s first book, The Theory of Moral Sentiments, said something quite different: “How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, thought he derives nothing from it, except the pleasure of seeing it”.

So what’s it to be? Are we totally self-interested, or do we care about the wellbeing of others? Are we individuals competing against each other for the biggest bit, or are we caring souls who co-operate with others to ensure everyone gets looked after?

Short answer: we’re both. But study conventional economics and you’re told only about the selfish, individualistic, competitive side of our nature. The moral, collective, co-operative side is assumed away. Government is seen not as a force for good, but as an alien force whose intervention in the market risks stuffing things up.

If you wonder why so many of the predictions economists make prove astray, that’s part of the reason. But some years back, two American economists associated with the Santa Fe Institute in New Mexico, Samuel Bowles and Herbert Gintis, wrote A Cooperative Species, to try to balance the story.

In the process, they provide a more convincing explanation of why humans have become the dominant species on Earth – for good and ill.

They focus on the way humans co-operate with each other in many circumstances – including when hundreds of us work for a single business, which competes with other big businesses - and argue that we co-operate not only for self-interested reasons, but also because we are genuinely concerned about the wellbeing of others.

We try to uphold “social norms” of acceptable behaviour, and value behaving ethically for its own sake. For the same reasons, we punish those who exploit the co-operative behaviour of others.

“Contributing to the success of a joint project for the benefit of [your] group, even at a personal cost, evokes feelings of satisfaction, pride, even elation,” they say. “Failing to do so is often a source of shame or guilt.”

We came to have these “moral sentiments,” in Smith’s words, because our ancestors lived in environments, both natural and as constructed by humans, in which groups of individuals who were predisposed to co-operate and uphold ethical norms tended to survive and expand relative to other groups, thereby allowing these “pro-social” motivations to proliferate.

So they explain our motivations for caring about the wellbeing of others: we do it because it makes us feel good. But they also explain the distant evolutionary origins of our disposition to co-operate and its perpetuation to the present day.

Co-operation – engaging with others in a mutually beneficial activity - was part of the behaviour of homo sapiens when we were still living on the African savannah. We formed bands to make us more successful in hunting big animals.

But though co-operation is common in many species, human co-operation is exceptional in that it extends beyond our close relatives – whom we look after in obedience to our evolutionary urge to replicate our species – to include even total strangers. And we co-operate on a much larger scale than other species except the social insects, such as ants and bees.

We co-operate in political and military objectives as well as more prosaic everyday activities: collaboration among the employees in a firm, exchanges between buyers and sellers, and the maintenance of local amenities among neighbours.

So, though they don’t see it in these terms, economists focus on a form of co-operation that involves “reciprocal altruism”. Buyers benefit sellers; sellers benefit buyers.

But human co-operation goes much further, in that it takes place in much larger groups and in circumstances that are unlikely to be repeated. Why do people tip while passing through a country town? In my own town I have reason to care about my reputation. But if I’m in your town, why does it not occur to me to cheat you in some way?

Much experimental and other evidence shows that people gain pleasure from co-operating, or feel morally obliged to. On the other hand, people enjoy punishing those who exploit the co-operation of others, or feel morally obligated to do so.

“Free-riders,” as economists call them, frequently feel guilty and, if they are sanctioned by others, they may feel ashamed.

We may have started out co-operating to hunt wild animals and mind other people’s children, but today we co-operate to enjoy the benefits of “the division of labour” (we each specialise in something we’re good at), of market exchange and the pursuit of economies of scale (in irrigation, factories, information networks) and even warfare.

And we made all this work better by inventing governments capable of enforcing the rights to property and providing incentives for the self-interested to contribute to common projects.

If you’re virtuous, don’t be afraid to signal it to the world

I’m troubled by the fashion of accusing others of “virtue signalling”. This world could use more virtue and less vice. And if people want others to see their virtue, well, there are worse sins.

Usually, it’s an accusation hurled at those on the other side of the political fence as a way of impugning their motives. They’re not genuinely virtuous, they just want people to think they are when they’re not.

They want to be seen as better than we are. They want me to feel guilty for not being as good as them, but I’m not buying that. I may be motivated by self-interest in the government policies I advocate, but so are they – they’re just pretending otherwise.

You can rationalise such a response by using the assumption of the neo-classical economic model that economic agents (you and me) are always and only motivated by self-interest. Altruism doesn’t exist. When I help someone, I’m doing so only because it makes me feel good.

In truth, social psychology has found plenty of evidence for the existence of altruism. It’s associated with another truth: homo sapiens’ success as a species is owed as much to co-operation as to competition.

I remember how shocked I was years ago to hear a top Treasury official refer with contempt to the Australian Council of Social Service – the peak body representing welfare organisations, including the Salvos – as “the compassion industry”.

First time I’d heard that word used as a term of derision. It reminded me of a song we sang when I was a Salvo: “Except I am moved with compassion, how dwellest Thy Spirit in me?”.

The Treasury man’s claim was that the ACOSS people didn’t really care about the poor and needy, they’d just found a way to make their living by representing the interests of poor. They were no more than another lobby group with their hand out.

As social animals, humans form themselves into tribes – groups. We have a compulsion to divide the world into good guys and bad guys. Naturally, my group are the goodies but, unfortunately, your group are the baddies.

Each of us sees ourselves as good, but some others as bad. I’m genuinely virtuous, whereas you’re just pretending to be.

In truth, none of us is all good or all bad. All of us are good in some respects and bad in others. And psychologists tell us we’re all often guilty of hypocrisy – applying high standards in judging others’ behaviour while making excuses for our own.

Equally, much of what we do we do for mixed motives. Try this test (one I usually fail): when you’re giving money to charity, how do you answer when asked if you’d like your donation to remain anonymous?

It’s possible some of us do virtuous acts – or make statements in support of virtuous policies – without any genuine interest in the wellbeing of others. It’s possible, but I doubt it’s very common.

What’s much more likely is mixed motives: we’re genuine in our professed concern about others, but equally genuine in our desire to be seen by others as having such a concern. That’s not really hypocritical, just being human.

Because we’ve evolved as group animals, all of us care deeply about what others think of us. We want to be accepted by the other members of the group. And we fear being excluded from the group.

Like teenagers, we’re desperate to fit in. The more we look and act like the others, the more comfortable we feel.

(This points to a further weakness in the neo-classical model: its assumption that each of us is a rugged individualist who makes decisions – about what movie to see or what clothes to buy – totally without reference to what those around us are doing.)

Turns out humans are signalling animals. We’re always using what we do, what we say, the way we dress, to signal our virtues to others – including our conformity to the group’s norms of acceptable behaviour.

The economy abounds with people and businesses sending signals. The first three economists to realise this won the Nobel prize for their genius.

We resort to sending signals because neither we nor others have enough hard information about the people we deal with and who deal with us. The main message we send is: you can trust me to deal with you honestly.

In today’s economy we’re suffering from a loss of trust, caused by a lack of virtuous behaviour, which has damaged reputations. We need economic behaviour to be a lot more virtuous. As that virtue is signalled, others will join in and the group norm of acceptable behaviour will be restored.

Our bulldust detectors are on the blink

The world has always been full of bulldust, which is why everyone should come equipped with a bulldust detector.

Trouble is, we're living in a time of bulldust inflation. Some of the things we're being told are harder and harder to believe. But a lot of people's detectors seem to be on the blink.

Part of the reason for the step-up may be that there are so many people shouting that anyone else hoping to be heard has to start shouting too.

These thoughts are prompted by the runaway success of the claim that 40 per cent of jobs in Australia are likely to be automated in the next 10 to 15 years.

This is a fantastic claim in the original, dictionary sense: imaginative or fanciful; remote from reality.

And yet it seems many thousands of people have accepted its likelihood without question.

Similar predictions have been made about America, and are just as widely believed.

As I've written before, two economists, Jeff Borland and Michael Coelli, of Melbourne University, who didn't believe it – because they could find no evidence to support it – traced the origins of the claim and the flimsy assumptions on which it was based.

Which led them to ask the question I'm asking: why do people so readily believe propositions they should find hard to believe?

The authors found a quote from a leading American economist, Alan Blinder, of Princeton University, in his book, After the Music Stopped.

"The consequences of adverse economic events are typically exaggerated by the Armageddonists​ – a sensation-seeking herd of pundits, seers and journalists who make a living by predicting the worst.

"Prognostications of impending doom draw lots of attention, get you on TV, and sometimes even lead to best-selling books . . .

"But the Armageddonists are almost always wrong," Blinder concludes.

What? Journalists? Bad news?

Blinder is right in concluding we take a lot more notice of bad news than good. Borland and Coelli observe that "You are likely to sell a lot more books writing about the future of work if your title is 'The end of work' rather than 'Everything is the same'.

"If you are a not-for-profit organisation wanting to attract funds to support programs for the unemployed, it helps to be able to argue that the problems you are facing are on a different scale to what has been experienced before.

"Or if you are a consulting firm, suggesting that there are new problems that businesses need to address, might be seen as a way to attract extra clients.

"For politicians as well, it makes good sense to inflate the difficulty of the task faced in policy-making; or to be able to say that there are new problems that only you have identified and can solve," the authors say.

I'd add that if you're a think tank churning out earnest reports you hope will be noticed – if only so your generous funders see you making an impact – it's tempting to lay it on a bit thicker than you should.

By now, however, it's better known that there are evolutionary reasons why the human animal – maybe all animals – takes more interest in bad news than good news.

It's because we've evolved to be continually searching our environment for signs of threat to our wellbeing.

All of us are this way because we've descended from members of our species who were pretty nervy, cautious, suspicious types. We know that must be true because those of our species who weren't so cautious didn't survive long enough to have offspring.

In ancient days, the threats we were most conscious of were to life and limb – being eaten by a wild animal. These days we keep well away from wild animals, but there are still plenty of less spectacular, more psychological threats – real or imagined – to our wellbeing.

This instinctive concern for our own safety is no bad thing. It helps keep us safe. It's an example of the scientists' "precautionary principle" – the dire prediction may not come to pass, but better to be on the safe side and take out some insurance, so to speak.

By contrast, failing to take notice of good news is less likely to carry a cost.

Except that, like many good things, it can be overdone. If we're too jumpy, reacting to every little thing that comes along, we're unlikely to be terribly happy. And unremitting stress can take its toll on our health.

Which brings us to the media. Journalists didn't need evolutionary psychologists to tell them the customers find bad news more interesting. Bad news has always received a higher weighting in the assessment of "newsworthiness".

But I have a theory that the news media have responded to greater competition – not just between them but, more importantly, with the ever-increasing number of other ways of spending leisure time – by turning up the volume on bad news.

This can create a feedback loop. People wanting their messages to be broadcast by a media that's become ever-more obsessed by bad news respond by making those messages more terrible.

I'm not sure the media have done themselves a favour by making the news they're trying to sell more depressing, BTW.

But Borland and Coelli offer a further possible explanation of why we're inclined to believe that the technological change which has been reshaping the jobs market for two centuries without great conflagration is about to turn disastrous: the cognitive bias that causes people to feel "we live in special times" – also known as "this time is different".

"An absence of knowledge of history, the greater intensity of feeling about events which we experience first-hand, and perhaps a desire to attribute significance to the times in which we live, all contribute to this bias," they say.

If so, a lot of people will continue believing stuff they should doubt.

Darwin improves on Adam Smith

What can the theory of evolution tell us about how the economy works? A lot. But probably not what you think it does.

Famous economists such as Joseph Schumpeter (author of the notion of "creative destruction") and Milton Friedman, and the contemporary economic historian Niall Ferguson, have viewed economies as Darwinian arenas: competition among firms reflects the ruthless logic of natural selection. Firms struggle with each other, with successful firms surviving and unsuccessful ones dying.

Thus evolution seems to support three pillars of the conventional, neoclassical model of the economy. First, that "economic actors" are self-interested, second, that self-interest works to the good of the public (propelling Adam Smith's "invisible hand") and, third, that together these lead the market to deliver the community ideal outcomes ("optimisation").

But there's a basic fault in this contention, as Dominic Johnson, of Oxford University, Michael Price, of Britain's Brunel University, and Mark van Vugt, of Amsterdam's VU University, point out in their paper, Darwin's Invisible Hand.

In conventional economics, "economic actors" can be either individuals or firms, although the theory tends to treat firms as though they were individuals. In reality, however, firms are groups of individuals - in the case of big national and multinational companies, thousands of them in one firm.

So if Darwinian selection applies to competitive markets, this implies that selection pressure acts on groups, not individuals. And group selection, as opposed to conventional Darwinian selection at the individual level, leads to the emergence of traits that act against self-interest.

With group selection, "we should expect the suppression of self-interest among individuals, not its flourishing", the authors say.

"Firms with less self-interested workers will compete more effectively and spread at the expense of firms with more self-interested workers, which will compete less effectively and decline. In other words, the model predicts nasty firms but nice people.

"Firms vie for market share and profits, group selection would predict, while individuals within those firms sacrifice their own interests for the good of the group. They will work long hours, accept low status and low salaries, co-operate with each other, share resources, accept hierarchy, obey their bosses, volunteer for extra duties and never help - or move to - rival firms."

Does that sound realistic to you? No, me neither.

"In reality," the authors say, "firms are made up of individual human beings, with various goals and motives but, most importantly, considerable self-interest.

"Darwinian selection at the level of groups implies that the interests of group members are weaker or synonymous with the interests of the group as a whole. In the real world, they are not. There is often some overlap, of course: the boss will want his workers to perform well; the workers will want the firm to survive.

But we also have strong personal desires for salary, status, rank, reputation, free time and better jobs.
"In short, any evolutionary model must account for two opposing processes that operate simultaneously: competition between firms and competition between the individuals within them."

So the authors are adherents to a relatively new school of thought holding that selection occurs at both levels: "multi-level selection theory". And this leads them to conclude that taking account of the role of evolutionary selection doesn't really bolster the conclusions of the neoclassical model.

Economic actors are self-interested only sometimes. Self-interest promotes the public good only sometimes. And these things mean markets produce optimal results only sometimes.

Great. But where does that get us? The authors argue that being more realistic by integrating the factors at work at group level with those at work at the individual level allows us to make better predictions on which interests - individual or group - will dominate in particular circumstances.

"A one extreme, if selection among groups is frequent and severe, we may expect an increased alignment of individual and group interests resulting in successful firms with hard-working, groupish, highly committed employees," they say.

"At the other extreme, if selection among groups is rare and weak, we may expect increased conflicts of interest resulting in inefficient firms and lazy, self-interested workers."

By group selection they mean cultural selection - some ideas and practices beat others - not biological selection. And, because ideas can spread so quickly, not needing to wait for genetic evolution to occur generation by generation, cultural evolution is much faster and more powerful.

The authors say competition between firms may be a quintessential example of cultural selection.

A weakness of the neoclassical model is that it exalts competition between economic agents while ignoring the co-operation within firms that is such an important part of real-world competition in markets.
The evolutionary approach, however, does much to illuminate the role of co-operation.

"Individuals are adapted to co-operate in groups but do so in individually adaptive ways," they say. "That is, we are co-operative, but only so long as our own individual costs and benefits are taken into account."

People want to be rewarded for their contribution but also to see that their reward doesn't compare badly with the rewards fellow workers are getting relative to their contribution.

But whereas the conventional economic model focuses on only monetary rewards and punishments, the evolutionary approach predicts that individuals will be powerfully motivated to strive for social status and prestige within their firm, even at the expense of material rewards or the risk of punishment.

The evolutionary approach also offers a better explanation of why individuals would want to take on stressful and time-consuming leadership positions, which are not always compensated by higher salaries: higher social status rewards.

The key to improving the performance of firms, we're told, is not to strike some inefficient compromise between the interests of individuals and their group but to work with the grain of human nature to bring individual and group interests into alignment. If you know what you're doing, this can be achieved relatively easily and at low cost.
