The behavioural scientist Dan Ariely once found himself chatting to a locksmith with a curious problem. The better he became at replacing locks, the less he got paid. In the early days, he explained, he might wrestle for hours with a jammed lock, but because his inexperience made his job look difficult, his customers would
An Iranian friend of mine recently brought me some gaz from Isfahan. Commonly known as Persian nougat, gaz is perhaps the most delicious thing I have ever eaten. The only thing to avoid is learning how it is made. Pistachio nuts are mixed with ‘honeydew’ collected from the angebin plant of the Zagros mountains, a
History records many well conceived and apparently logical grand plans for the betterment of mankind. Sadly such ideas almost always fail. Why is this? One possibility is that they fail precisely because they are logical. The dictates of logic require the existence of universally applicable laws. But humans, unlike atoms, are not consistent enough in
In the shadow of the Shard, not far from Borough Market, is a £1 billion public artwork, an allegorical sculpture entitled ‘What is wrong with the world today’ by the reclusive wunderkind Netwór Krail. It was officially unveiled by the Duke of Cambridge earlier this month. The reason you may not have read about this
Nearly ten years ago, a lorry driver known only as ‘Michael Harry K’ adopted an extreme response to combating what he saw as declining standards on the autobahns: he started shooting at other vehicles. In a four-year spree he fired around 700 rounds at cars and trucks before his arrest in June 2013. What helped
When I was ten, the two things we all expected to enjoy by 2020 were flying cars and videotelephony. What never occurred to us was that we might successfully invent one of these things and then fail to use it. Yet that has largely been the case with video conferencing. Is its day still to
At the risk of sounding like Jean Baudrillard, I would like to suggest that the internet revolution has not yet taken place. So far, lots of very clever people have performed amazing feats of technical ingenuity. But for the most part our collective behaviour has so far failed to change enough to truly benefit us.
Nine years ago, before Cambridge Analytica existed, I caught wind of a research project at Cambridge involving the online measurement of the ‘big five’ personality dimensions. These are usually listed by the acronym OCEAN or CANOE: Conscientiousness, Agreeableness, Neuroticism, Openness and Extraversion. I made a note to go to Cambridge to learn more but, being
The maximum amount you can save in an ISA for the tax year 2017-2018 is now £20,000. The maximum annual pension contribution is £40,000. Counterintuitively, these huge allowances are actually a disincentive for ordinary people to save. With a £5,000 ISA maximum, a modest saver had an impetus to save each year for fear of
Every now and then I try to invent a new scientific unit. I’ll never come up with anything as good as the millihelen — a unit of beauty sufficient to launch one ship — or the Sheppey, which is a distance of approximately seven-eighths of a mile defined as ‘the minimum distance at which sheep
There may be a very simple evolutionary reason why water does not really taste of anything, as I learned from the psychophysicist Mark Changizi. Pure water has no taste because our taste buds have been calibrated, very sensibly, not to notice it. For a few million years, the most important contribution taste buds made to
There exist in the annals of salesmanship certain ideas that are both highly immoral and wickedly clever. Before P. T. Barnum attached his name to circuses, he ran Barnum’s American Museum in Manhattan. From 1841 until its destruction by fire in 1865, this received more than 38 million visitors, each paying 25c. The entry fee
Recently the NHS postponed a large number of non-urgent operations to cope with what is known as the ‘annual winter crisis’. Naturally, this outcome was treated as a scandal in the press, and there were predictable calls for Jeremy Hunt to resign. But the fact that non-urgent operations are postponed is not by definition bad.
One of the funniest passages of writing I have read in the past few years appears within the pages of Richard Thaler’s memoir Misbehaving. He describes what happens when the University of Chicago economics faculty moves to a new location. The economists simply have to agree among themselves who will occupy each office in the
About 30 years ago, BT introduced a telephone handset with enormous keys. It was intended for people with serious visual impairment. Unexpectedly, it became their bestselling phone. There is a reason for this. The millions of people who wear spectacles or contact lenses typically remove them at night, making the normal tiny keys impossible to
At last. And just what you’ve been waiting for. The official Wiki Man guide to the best gadgets and gizmos for giving this Christmas. The Philips AirFryer, from £70-ish. Spectator readers may remember a craze for cooking things via a French method called sous-vide. Using this senseless technology, you could cook soggy food for days
One dietary fad that never made sense to me was the campaign against the consumption of eggs. Now call me an old Darwinist, but here we are having spent a few million years evolving into a bald monkey with prehensile thumbs, perfectly optimised as an egg-stealing machine, and yet the digestion of an omelette somehow
It took a spate of air disasters in the late 1970s, in particular the Portland crash of United Airlines Flight 173, for aviation experts to pay attention to something called Crew Resource Management. This is a set of procedures first conceived by Nasa with the aim of minimising human error in flight. UA173 — where
I hate to tell you this, but every time you watch television you are being duped. In fact there are only three accurate things you will ever see on television. These are the colours red, green and blue. Each pixel on a screen can transmit three colours only. If blue alone is illuminated, the screen
I love anything open late at night. Never mind ‘the sigh of midnight trains in empty stations’; even mundane activities like filling up with petrol become enjoyably Edward Hopperish after midnight. Often the places are so quiet you wonder why they bother opening at all. But it is a strange psychological fact that opening a
