Confession of a born essentialist

2009/12/15

We have an innate tendency to psychological essentialism. Bruce Hood articulates this tendency well (see his book Supersense). His most vivid example is the serial-killer’s shirt. If you are given a nice shirt – one that fits well and suits your style and wardrobe – and told that it once belonged to a serial killer, how will you react? Most people will avoid the shirt – even avoid touching it. Of course, the shirt contains no “serial-killer essence”, but the association sparks something deep our psychology: we want to avoid objects that are associated with bad things.

This was probably hugely adaptive in our evolutionary history: if you avoid touching things that have been handled by, say, a seriously ill person, you are less likely to become infected yourself. It doesn’t matter if the reason you avoid them is rooted in an accurate knowledge of the germ theory of disease or an improbable metaphysical notion of guilt-by-association – if it saves your life and is affected by your genes, it will give you a selective advantage over people without the trait, or with a weaker version of the same trait.

Essentialist psychology provides a compelling explanation for why people would believe in certain immaterial properties of matter even if the universe is completely material. Which leads some philosophical naturalists (humanists, atheists, etc) to smugly think that we’ve risen above the illusion: we see through the illusory sense that our instincts push us into. We aren’t tricked into god-belief or imagining a life after death.

Well, it’s not that easy.

I was playing with Kaia (my 2-year-old daughter), and she told me that her doll needed a nappy change*. As an expert, I was invited to conduct the procedure. I used a nose tissue to wipe the doll’s bottom.

When I went to put the tissue back in my pocket (for future use), I was momentarily overcome by my inner essentialist. I had a strong sense that the tissue was unclean. All simply because of an act of imagination!

I quickly realized what was happening, and put the tissue in my pocket anyway. In fact, once I became conscious of the illusion, it quickly dissipated. Thank goodness for skepticism. I wonder if I would have recovered as quickly if I had not, a few years ago, attended a talk here in Edinburgh given by Bruce Hood.

Have you ever had a “silly essentialist” moment like this? How did you react? How did you feel once you realized what was going on?

* I feel I should point out that this wasn’t one of those modern imagination-free dolls that actually produce wet nappies.

Some science news

2009/11/20

In a recent issue of Psychological Science (to which I am subscribed), three of the five research articles were on topics that I thought would be interesting to a general audience.

(I’m afraid the links are only to abstracts – you need to be an APS member or browse from a university which has a subscription in order to see the full article. If you think this is unfair, or contrary to the scientific spirit of open inquiry, I agree. See here or here for some discussion of the issue of open-access academic publishing.)

I should open with a warning: none of these articles is in my field of expertise, so my interpretation of the results and their applicability to life in general may be inaccurate. But I think some extrapolation is warranted.

Passersby

First, there’s an article examining how we decide which side we’ll go on when we approach an oncoming pedestrian on the sidewalk. Apparently, we use the direction their looking in as a cue to which side they’ll go on, and we choose the other side. Not life-changing, I know, but interesting.

Now for the caveat: this is a single scientific study, and as such was very limited scope. Gaze direction was the only cue they looked at. Body language, social conventions (such as “always pass on the left”), and other factors may also influence how such encounters are resolved.

Nevertheless, next time I’m unsure which side to pass someone on, I’ll consciously fix my gaze on one side and go that way, to see if that helps avoid that awkward mambo of mutual indecision.

Affirmation and persuasion

Second, there’s one about how self-affirmation affects our attention to persuasive messages. Moderate drinkers who participated in a self-affirmation exercise (in this case, writing about one of their best traits) were more likely than the control group to attend to threatening aspects of an article about the dangers of moderate to heavy drinking.

They did not find the same effect in heavy drinkers. Also, they just measured attention. That is, they did not follow up to see if the affirmation group changed their behaviour as a result of their increased attention.

However, I can remember several times when I’ve tuned out a message because it seemed mainly to be trying to persuade me out of some belief or activity I was attached to. Perhaps if I were to engage in some sort of affirmation, I would be more able and willing to hear such messages through. If the message contains a good reason to change, then my increased attention might enable me to take that reason on board. If not, then I’ll still be free to reject the message – but I’ll do it because of the content and not because it’s threatening to me.

Self-restraint and Impulsive Behaviour

Third, there’s an article examining the connection between perceived self-restraint and actual impulsive behaviour. Briefly, if we think that we have great self-restraint, then we are more likely to put ourselves in situations which will test us, and ultimately we are more likely to engage in impulsive behaviour.

I’m not sure how broadly this can be extrapolated, but the “moral” that I draw from this study is that I should try to avoid overconfidence when it comes to my vices. The most pernicious of these, for me, is a desire to remain connected to the Internet. If I need to pay attention to something else (parenting, say, or dealing with bills), then an open laptop on the table is a bad idea.

I love science. I love cosmology, biology, physics, chemistry – the whole bunch. Every science I’ve come across has something to inspire awe, wonder, and delight. But nothing beats psychology for churning out knowledge with direct relevance to the way we live our lives.

Deena and I recently bought Richard Wiseman‘s new book, 59 Seconds, which promises to be a delicious exploration of just this sort of thing. A science-based self-help book. Awesome.

Turing apology

2009/09/11

A few days ago, I pointed out a petition calling for a posthumous apology to Alan Turing for his disgraceful treatment by the British government when it became known that he was gay.

Well, Gordon Brown has delivered. He has issued what seems to me to be a very frank apology, acknowledging not only Turing’s significant contributions to computing and to the outcome of the Second World War, but also the injustice of his treatment at the hands of the country he had served so well.

As of this moment, there are 31070 signatures on the online petition. (I assume the petition is closed, now that its aim is achieved, but cannot find a clear statement to that effect.)

Here is the full text of the Prime Minister’s statement:

2009 has been a year of deep reflection – a chance for Britain, as a nation, to commemorate the profound debts we owe to those who came before. A unique combination of anniversaries and events have stirred in us that sense of pride and gratitude which characterise the British experience. Earlier this year I stood with Presidents Sarkozy and Obama to honour the service and the sacrifice of the heroes who stormed the beaches of Normandy 65 years ago. And just last week, we marked the 70 years which have passed since the British government declared its willingness to take up arms against Fascism and declared the outbreak of World War Two. So I am both pleased and proud that, thanks to a coalition of computer scientists, historians and LGBT activists, we have this year a chance to mark and celebrate another contribution to Britain’s fight against the darkness of dictatorship; that of code-breaker Alan Turing.

Turing was a quite brilliant mathematician, most famous for his work on breaking the German Enigma codes. It is no exaggeration to say that, without his outstanding contribution, the history of World War Two could well have been very different. He truly was one of those individuals we can point to whose unique contribution helped to turn the tide of war. The debt of gratitude he is owed makes it all the more horrifying, therefore, that he was treated so inhumanely. In 1952, he was convicted of ‘gross indecency’ – in effect, tried for being gay. His sentence – and he was faced with the miserable choice of this or prison – was chemical castration by a series of injections of female hormones. He took his own life just two years later.

Thousands of people have come together to demand justice for Alan Turing and recognition of the appalling way he was treated. While Turing was dealt with under the law of the time and we can’t put the clock back, his treatment was of course utterly unfair and I am pleased to have the chance to say how deeply sorry I and we all are for what happened to him. Alan and the many thousands of other gay men who were convicted as he was convicted under homophobic laws were treated terribly. Over the years millions more lived in fear of conviction.

I am proud that those days are gone and that in the last 12 years this government has done so much to make life fairer and more equal for our LGBT community. This recognition of Alan’s status as one of Britain’s most famous victims of homophobia is another step towards equality and long overdue.

But even more than that, Alan deserves recognition for his contribution to humankind. For those of us born after 1945, into a Europe which is united, democratic and at peace, it is hard to imagine that our continent was once the theatre of mankind’s darkest hour. It is difficult to believe that in living memory, people could become so consumed by hate – by anti-Semitism, by homophobia, by xenophobia and other murderous prejudices – that the gas chambers and crematoria became a piece of the European landscape as surely as the galleries and universities and concert halls which had marked out the European civilisation for hundreds of years. It is thanks to men and women who were totally committed to fighting fascism, people like Alan Turing, that the horrors of the Holocaust and of total war are part of Europe’s history and not Europe’s present.

So on behalf of the British government, and all those who live freely thanks to Alan’s work I am very proud to say: we’re sorry, you deserved so much better.

Gordon Brown

Well done, Mr Brown.

Call for apology to Turing

2009/09/01

This is a story of a national hero who was censured by his country and died alone on account of love.

Alan Turing was a key figure in the early years of computer development, before the Second World War. During the war, he was a key figure in the British team that decrypted the German Enigma cipher. Their contributions gave the Allies a pivotal advantage over their adversaries.

He was prosecuted for “gross indecency” because he’d had consensual sex with another man in the privacy of his own home. His work with the British intelligence service was over, and he was given the choice between chemical castration or prison. He chose the hormone treatment. Two years later, he committed suicide. He was 41 years old.

The last word the British government had to say about him was that his private actions, harming nobody, merited ruining his life.

Turing was a very prominent individual; I am sure that many other lives, both prominent and not, were needlessly ruined by this shameful law (happily repealed across Britain by the late 1970s).

There is now a call for the British government to apologise for its treatment of Turing. Given that an apology would be very easy to issue, would cost little and harm nobody, I think it is worth doing.

If you are a British resident and think this is worth two minutes of your time, please go sign the petition.

Also, let me know what you think of this sort of apology. Is it worthwhile? Is it a waste of time? Is is otherwise inappropriate? What consequences do you think such an apology would have, in terms of people’s actions and their attitudes?

Greater than ourselves

2009/05/25

How many times has someone has asked you, as a non-believer (whatever it happens to be that you don’t believe in), “Don’t you believe in anything greater than yourself?” For me, the question most often comes up when I declare a naturalistic worldview. No god? No afterlife? Then what do you look to for hope and inspiration?

Today, I’m just going to offer a couple of items on one source of inspiration and hope from something greater than myself: the cosmos.

Even as a simple empirical matter, there are worlds beyond count, many grander than our own in their different ways. The image to the right is one example – click on it, enlarge it, try to get your head around the vast grandeur of everything that lies outside our little planetary cocoon (a cocoon that is itself much vaster and more beautiful than anything I or any human can claim credit for).

Or try this simple image. Some of you will recognize it. Some will know the phrase often associated with it: the Pale Blue Dot.

This is the last image of Earth taken by the Voyager probe, as it passed Saturn on its journey out of the Solar System.

Do I believe in anything greater than myself? Yes. In my boldest moments, I try to go beyond simply accepting the facts of astronomy as told in numbers. I try to take into the very centre of my self the understanding given by astronomers and scientists. To grasp the enormity of everything that exists, and to accept my humble place in this reality.

It is a difficult task for my limited, pragmatic ape brain. But I have the help of some great poet-scientists of yesterday and today. Here’s one of them, Carl Sagan – the man we can thank for the Pale Blue Dot image – contemplating its meaning for us who live on that dot:
