Psychology

A leading article appeared in Nature last week in defence of intelligence research. It lamented the fact that it is not included on the undergraduate psychology curricula of many leading US universities, and attributed this to its association in the minds of students and faculties with elitism and racism. That, in turn, is due to the misuse of intelligence research in the past by eugenicists and ‘race scientists’ to justify their poisonous beliefs. The article expressed the hope that this toxic baggage can be discarded and intelligence rehabilitated as an important strand of psychology. This optimism is often shared by academics who study the genetic basis of human differences; not

According to a front-page story in the Times earlier this week, your personality does change over the course of your lifetime. A study carried out by Edinburgh University found that the personalities of a group of people in their seventies had changed significantly since they were schoolchildren in the 1950s. Traits like perseverance, self-confidence and originality changed ‘beyond recognition’, according to the study’s leader Dr Mathew Harris. He was surprised, because the conventional wisdom among social psychologists is that these characteristics remain stable over a person’s lifetime. At first glance, my own personality would appear to bear out these findings. Between the ages of 14 and 40 I was something

Don’t know if you’ve noticed, but middle-class rules now require that every dinner party cheeseboard must contain at least two cheeses which aren’t very nice. Typically one will be a veiny French cheese which is not as good as Stilton; another may be that foreign thing with rind on it which isn’t nearly as good as Cheddar. I was baffled by this for a long time, until I realised that these cheeses are not bought to be eaten, but to signal the sophistication of the occasion. Economists might call them Veblen cheeses. (One day someone should make an inedible cheese called Veblenne. They’d make a fortune.) There are many forms

Almost every popular commercial product owes its success to two different qualities. First, it does the job it is ostensibly designed to do pretty well. Secondly, it has some quality that you might call ‘limbic appeal’. It delights or soothes our unconscious mind in ways which defy objective measurement. Much as it delusionally believes that it runs the show, the power granted to conscious reasoning within the brain is that given to a slightly colour-blind, utilitarian man when he buys a sofa with his wife. The man may have his own preferences, but he has a minimal role in the selection, involving as it does many complex factors that defy

We recently moved -offices from Canary Wharf to Blackfriars bridge. When you move after a long time in one place, you notice the surprising ways in which your behaviour is subliminally affected by your surroundings. On my second day in the new office, someone came from Victoria to meet me. After about 25 minutes of useful conversation, I thanked them and they left. Something about the encounter seemed strange; I suddenly realised that, back in the old office, I’d never had such brief meetings. Instinctively it felt discourteous to give anyone who had made the longer trip to Canary Wharf any less than 45 minutes of your time. This sense

When I was at school in the 1970s, some of the richer kids would come back from their summer holidays with jaw-dropping tales about the wondrous places they had visited. Chief among them, as I remember, was Schiphol airport. ‘It was amazing,’ they would say. ‘There were shops and restaurants and stuff,’ and you could buy a Walkman for some insanely low price. A few others vainly tried to trump the Schiphol crowd by fancifully claiming to have been to Frankfurt airport and seen an actual sex shop there — an assertion widely disbelieved, certainly by me, until I used the airport 15 years later and discovered it was perfectly

In many ways a satnav is a miraculous device. A network of US military satellites more than 10,000 miles above the surface of the Earth, each broadcasting a signal with little more power than a 100-watt light bulb, allows a device in your satnav or mobile phone to triangulate your location on the ground to within seven yards or so. The system is so finely tuned that the clocks aboard the satellites must be calibrated to run 38 microseconds a day slower than Earth time to correct for the effects of general and special relativity. This allows your phone to know your location and, after factoring in real-time traffic information,

What happens when 95 per cent of people like something, but 5 per cent of people prefer something else? You might think natural democracy would prevail: that the 5 per cent would acquiesce and go along with the taste of the majority. Not necessarily. In many cultural settings, it is common for a small, intransigent minority to beat a much larger, tolerant majority. If you’re hosting a dinner party, for instance, all it takes is one git with a spurious ‘fenugreek intolerance’ to veto your best lamb curry. You might call this ‘the asymmetry of tolerance’, where certain social systems end up calibrated to suit their most inflexible component. If the majority prefers
