How should we reduce the wellbeing costs of poverty?
22 Apr 2022
Unless you have been in hiding for the past forty years, you will know that even in countries that are rich in aggregate, poverty is really bad for wellbeing – bad for physical health, bad for mental health, and bad for satisfaction with life in general. Definitions of poverty for developed nations generally include some notion of relativeness: it’s about having less than most people in your society. Under this definition, you can’t ever entirely make poverty go away, since numerical equality of income and wealth is unlikely (though, of course, you can make the gaps smaller, and this seems generally to be a good idea, for all kinds of reasons including those discussed below). So it is worth asking: are there places where the wellbeing burden of relatively low income is smaller, and places where it is bigger? And what do those places do differently? I have been having a look at this using the data from the European Quality of Life Survey (2012). (This is a digression from a larger ongoing project with Tom Dickins investigating the consequences of inequality using that dataset, see pre-registration here. There are more details of the sample and measures in that document). … Continue reading “How should we reduce the wellbeing costs of poverty?”

Breaking cover on the watching eyes effect
28 Mar 2022
I have seldom had much to say on the watching eyes effect. Even though it is the most cited research I have ever been involved in, it was always a side project for me, and also for Melissa Bateson, and so neither of us has been very active in the debate that goes on around it. Along with our students, we did an enjoyable series of field experiments using watching eyes to impact prosocial and antisocial behaviour. The results have all been published and speak for themselves: not much more to say (we really don’t have a file drawer). However, I have just finished reading not one but two unrelated books (this one and this one) that cite our watching eyes coffee room experiment as a specimen of the species ‘cute psychology effect that failed to survive the replication crisis’, and so I feel I do need to break cover somewhat and make some remarks. In our coffee room experiment, we found that contributions to an honesty box for paying for coffee substantially increased when we stuck photocopied images of eyes on the wall in the coffee corner, compared to when we stuck images of flowers on the wall. This … Continue reading “Breaking cover on the watching eyes effect”

Live fast and die young (maybe)
18 Feb 2022
Quite a few big ideas have made it across from evolutionary theory into the human sciences in the last few years. I can’t think of any that has been more culturally successful than the ‘live fast, die young principle’. This principle, which was originally articulated by George C Williams in the late 1950s, says something like the following: if you live in a world where the unavoidable risk of mortality is high, you should prioritise the present relative to the future. Specifically, you should try to reproduce sooner, even at the expense of your neglected body falling apart down the line. After all, what is the point in investing in longevity when some mishap will probably do you in anyway before you reach a peaceful old age? The principle was originally invoked to explain inter-species differences in the timing of reproduction, and in senescence (the tendency of bodies to fall apart in multiple ways after a certain number of years of life, without clear external causes). But it has come to crop everywhere: in psychology (to explain individual differences in impulsivity, and the impact of early-life trauma), in sociology (to explain socioeconomic differences) , in anthropology and history (to explain … Continue reading “Live fast and die young (maybe)”

The bosses pretend to have theories, and we pretend to test them
17 May 2021
Leo Tiokhin has hosted a new blog series on the use of formal models in metascience and, more generally, in psychology. The starting point for the series is the increasing recognition that psychology’s weaknesses don’t just lie in its recent replicatory embarassments. The underlying theories that all those (possibly non-replicable) experiments aim to test are also weak. That is: the theory as stated could give rise to multiple patterns in the data, and the data could be compatible with multiple theories, given how vaguely these are stated. In my contribution to Leo’s series, I invoked the old Soviet joke: the bosses pretend to have theories, and we pretend to test them. Several contributors to the series point out the virtue, given this problem, of formalizing theories in mathematical or computational models. This undoubtedly has merit: if you convert a verbal psychological theory into a formal model, then you expose all your tacit assumptions; you are forced to make decisions where you had left these vague; you discover if your conclusions really must follow from your premises; and you are left with a much tighter statement of what your do-or-die predictions are. This is all good, and true. However, my contribution, … Continue reading “The bosses pretend to have theories, and we pretend to test them”

My muse is not (or, possibly, is) a horse
30 Apr 2021
I’ve written one thing in my life that people really want to read: a 2017 essay called Staying in the game. When I first posted it, the unprecedented traffic over a couple of days caused my web site host to suspend the service. A lot of people commented or emailed when it came out. Many people have read it since. Every few months it has a little outbreak of virality, usually via Twitter or Facebook. The most recent one was this week. Given that people seem to be interested in the essay, and more generally in understanding the creative processes of their fellow academics, I thought it might be fun to write some more about the history of this essay, how it came about. Staying in the game existed for some time, in several versions. It tries to do several things. It contains a self-help or how-to guide for actual or aspiring academics, a kind of Seven habits of moderately effective (and slightly nerdy) people. There is something of the confessional in it (and that, I think, is what people, especially younger academic colleagues, like). I wanted to say that it is OK, normal, permitted, to struggle in your academic … Continue reading “My muse is not (or, possibly, is) a horse”

Why does inequality produce high crime and low trust? And why doesn’t making punishments harsher solve the problem?
21 Jan 2021
Societies with higher levels of inequality have more crime, and lower levels of social trust. That’s quite a hard thing to explain: how could the distribution of wealth (which is a population-level thing) change decisions and attitudes made in the heads of individuals, like whether to offend? After all, most individuals don’t know what the population-level distribution of wealth is, only how much they have got, perhaps compared to a few others around them. Much of the extra crime in high-inequality societies is committed by people at the bottom end of the socioeconomic distribution, so clearly individual-level of resources might have something to do with the decision; but that is not so for trust: the low trust of high-inequality societies extends to everyone, rich and poor alike. In a new paper, Benoit de Courson and I attempt to provide a simple general model of why inequality might produce high crime and low trust. (By the way, it’s Benoit’s first paper, so congratulations to him.) It’s a model in the rational-choice tradition: it assumes that when people offend (we are thinking about property crime here), they are not generally doing so out of psychopathology or error. They do so because they … Continue reading “Why does inequality produce high crime and low trust? And why doesn’t making punishments harsher solve the problem?”

Why is Universal Basic Income suddenly such a great idea?
16 Apr 2020
The idea of an unconditional basic income, paid to all (UBI), has a long history. Very long in fact. Yet, although the policy has been deemed philosophically and (sometimes) economically attractive, it has generally languished in the bailiwick of enthusiasts, mavericks, philosophers and policy nerds (these are, by the way, overlapping categories). But now, with the global pandemic, UBI is very much back in the spotlight. Previous sceptics are coming out with more enthusiastic assessments (for example, here and here). Spain apparently aims to roll out a UBI scheme ‘as soon as possible‘ in response to the crisis, with the aim that this becomes a ‘permanent instrument’ of how the Spanish state works. And even the US Congress relief cheques for citizens, though short-term, have a UBI-like quality to them. So why, all over the place, does UBI suddenly seem like such a great idea? Answering this question requires answering another, prior one: why didn’t people think it was such a great idea before? To understand why people’s objections have gone away, you need to understand what they were before, as well as why they seem less compelling in this time of upheaval. UBI is a policy that appears to … Continue reading “Why is Universal Basic Income suddenly such a great idea?”

This is no time for utilitarianism!
8 Apr 2020
An interesting feature of the current crisis is the number of times we hear our leaders proclaiming that there are not weighing costs against benefits: ‘We will do whatever it takes!’. ‘We will give the hospitals whatever they need!’. And even, memorably, from the UK Chancellor, ‘We will set no limit on what we spend on this!’. No limit. I mean when did the UK Treasury ever say that? Maybe only during the war, which is a clue. Such statements seem timely and reassuring just at the moment. When people are timorous enough to question whether some of this largesse might actually be sensible – for example, whether the long-term costs of some decisions might be greater than the benefits – it seems in incredibly poor taste. But people are dying! Those commentators are roundly excoriated on social media for letting the side down. All of this is something of a puzzle. The whole essence of evidence-based policy, of policy modelling, is that you always calculate benefits and costs; of course this is difficult, and is never a politically neutral exercise, given that there are so many weightings and ways one might do so. Nonetheless, the weighing of costs and … Continue reading “This is no time for utilitarianism!”

Are people selfish or cooperative in the time of COVID-19?
25 Mar 2020
On March 12th 2020, in a press conference, the UK’s chief scientific advisor Patrick Vallance stated that, in times of social challenge like the current pandemic, the people’s response is an outbreak of altruism. On the other hand, we have seen plenty of examples in the current crisis of bad behaviour: people fighting over the last bag of pasta, price gouging, flouting restrictions, and so on. So there is probably the raw material to tell both a positive and a negative story of human nature under severe threat, and both might even be true. Rebecca Saxe and I are trying to study intuitive theories of human nature. That is, not what people actually do in times of threat or pandemic, but what people believe other people will do in such times. This is important, because so much of our own behaviour is predicated on predictions about what others will do: if I think everyone else is going to panic buy, I should probably do so too; if I think they won’t, there is no need for me to do so. We have developed a method where we ask people about hypothetical societies to which various events happen, and get our … Continue reading “Are people selfish or cooperative in the time of COVID-19?”

The view from the top of the hierarchy of evidence
1 Oct 2019
About five years ago I began doing meta-analyses. (If, as they say, you lose a tooth for every meta-analysis you conduct, I am now gumming my way through my food.) I was inspired by their growing role as the premier source of evidence in the health and behavioural sciences. Yes, I knew, individual studies are low-powered, depend on very specific methodological assumptions, and are often badly done; but I was impressed by the argument that if we systematically combine each of these imperfect little beams of light into one big one, we are sure to see clearly and discover The Truth. Meta-analysis was how I proposed to counter my mid-life epistemological crisis. I was therefore depressed to read a paper by John Ionnidis, he of ‘Why most published research findings are false’ fame, on how the world is being rapidly filled up with redundant, mass produced, and often flawed meta-analyses. It is, he argues, the same old story of too much output, produced too fast, with too little thought and too many author degrees of freedom, and often publication biases and flagrant conflicts of interest to boot. Well, it’s the same old story but now at the meta-level. Just because … Continue reading “The view from the top of the hierarchy of evidence”
