Psychology

It is a trick which often works on children. Do not tell them to eat vegetables; instead ask whether they want broccoli or spinach. Question such as ‘Red or white?’ or ‘Still or sparkling?’ are examples of placebo choice: a psychological hack which works rather like the placebo ‘door close’ buttons in lifts (which are usually not wired up to anything but exist to give impatient people the illusion of control). Such questions give the feeling of choice without offering much at all. The hack needs to be viewed with caution since it can subtly transmute ‘I prefer B to A’ into ‘I want B’. Watch out for canny estate

I am surprised no more attention has been given to Martin Vander Weyer’s suggestion in The Spectator two weeks ago that a mansion tax should be levied on those buyers who pay no other UK tax. Why has it taken so long for anyone to raise this idea? Where tax paid against income should be set against tax paid on property? Let’s consider this question in psychological terms. Assume that you are eager to buy a particular house but someone else decides he wants to live there too. He is twice as rich as you are and so comfortably outbids you. Whatever the other person’s moral worth, you know two

Now that most taxi drivers use satnavs, should ‘the Knowledge’ be abolished? Shouldn’t we ditch the requirement that all London black cab drivers spend several years acquiring an insanely detailed knowledge of London before obtaining a badge? In cabbie folklore, the model for the Knowledge was first suggested by Prince Albert. True or not, there is something German about the notion that every tradesman should have a qualification. And the test is teutonically stringent: more than 70 per cent of applicants fail or drop out. It demands that the prospective driver memorise 25,000 streets and 20,000 landmarks within six miles of -Charing Cross. Now, useful as it once was, many people

An ardently left-wing friend of mine is travelling over from Thailand next week to look for a private school for his daughter. My email to him was short. It read ‘Charles Darwin 1, Karl Marx 0’. Nobody among the sharp-elbowed middle class ever allows his political convictions to override the pursuit of a good education for his children. They will pay or move house or, if those two approaches fail, rapidly reawaken a long-dormant interest in Catholicism. One reason for this inconsistency is explained in four words by the evolutionary theorist and sociobiologist E.O. Wilson, by common consent the world’s leading expert on ants. His simple observation on Marxism was

You will be scandalised by the suggestion, of course, especially those of you who spend several hours every week drinking it, reading about it or discussing it. But most wine is actually rubbish. I’ll let you off the hook if you drink wine only with food. But wine drunk on its own is often a terrible drink, usually consumed for appearances’ sake, or because the drinker lacks the confidence to complain, or for want of any alternative source of alcohol. Our judgment of wine is also notoriously flaky — influenced as much by the appearance and weight of the bottle as by its contents. One winemaker sent the same wine

‘Never play cards with a man called Doc. Never eat at a place called Mom’s. And never sleep with a woman whose -troubles are worse than your own.’ These were Nelson Algren’s Three Rules of Life. You may have noticed a few more ‘rules of life’ appearing recently. After years of our being advised to drink some forgettable number of units of alcohol every week, a new rule seems to have emerged: ‘Don’t worry much about how much you drink but do abstain from alcohol completely for at least two days in seven.’ The hottest diet of the moment, sometimes called the 5:2 Diet, lets you eat freely except for two
