Some years ago, two British supermarket chains needed to place a large order for replacement trollies. They had to decide what ratio of full-depth and shallow trollies to order, and how best to allocate them between stores. One of them amassed mounds of demographic data and tried to construct an elaborate optimisation model. The second
Outside mathematics, the word ‘commute’ can mean two things. Mostly it refers to the act of making a daily journey between one’s home and work; more rarely it describes replacing one penalty with another — as in ‘the Home Secretary commuted the death sentence to one of life imprisonment’. The curious may wonder why one
In 1991, 67 per cent of 25- to 34-year-olds owned their own home. In 2016, that figure had fallen to 38 per cent. The average house price in the UK is eight times the average wage, this ratio having doubled since 1998. Half of first-time buyers in Britain are now dependent on the Bank of
There is a famous chart which shows the time it took for various technologies to be adopted by 50 million people. From its introduction, the telephone took 75 years to reach 50 million users. For radio, it was 38; for television, 13; for the world wide web, merely four. Online services are faster still. Facebook
I’d hoped to spend this week writing about my new Geberit Japanese-style toilet, but since the grout is not yet dry, all you filthy toilet-gaijin will have to wait until the new year for my review. So I thought I’d write instead some reviews of my favourite gadgets of the year. But since our real
One of the more tedious tropes of recent years is for journalists to bemoan the rise of populism while busily casting about for some dark force to which to attach the blame. Mark Zuckerberg, Google, nameless Russians, an uneducated populus, social media, whatever. One avenue that is rarely explored is that a major cause of
I have just returned from Canada, which seems to share Britain’s new-found obsession with veganism. There, chains such as Burger King and KFC are offering plant-based alternatives to meat-based meals. Five years ago could anyone have predicted this? True, vegetarianism has been growing for many years, but did anyone foresee its most extreme variant rapidly
Whenever I use the security lane at an airport, I enjoy watching people retrieving their bags and metallic items when they emerge from the X-ray machine. You can quickly divide the population into two: a small minority of ‘logistically aware’ systems-thinkers and the logistically challenged majority. To anyone with a grasp of systems thinking, it

I recently learned from a doctor friend that salt isn’t necessarily bad for you. Yes, there is a minority whose blood pressure isdriven haywire by eating the stuff, but most people can consume it without much risk. The reason we are formally advised to avoid salt is that lowering salt consumption improves public health on
It’s difficult to go into the office nowadays, since most of my colleagues are so distraught by the prospect of a no-deal Brexit that they rarely speak. The finance department have painted European flags on their faces for solace, and spend the day staring blankly out of the window sobbing over a tear-stained picture of
In 1891, a 29-year-old man moved from Philadelphia to Chicago intending to start a business. With $32 to his name, he began by selling scouring soap. Hoping to boost sales, he gave away small packets of baking powder with every purchase. Soon he found that the baking powder was more popular than his soap, so

In last week’s Spectator, Martin Vander Weyer replied to a couple with a baby who had sought his advice on accepting a low offer for their cramped London flat to buy a house in commuterland. Their fear was that, if Brexit led to a property crash, they could face negative equity. Should they call the
Recently I suggested a new approach to commuter-train overcrowding. It simply involved reformulating the problem by accepting that not all overcrowding is equally bad: 100 people forced to stand 10 per cent of the time do not experience anything like the same irritation as ten people who have to stand 100 per cent of the
Today we suffer disillusion, not because we are poorer than we were — on the contrary, even today we enjoy, in Great Britain at least, a higher standard of life than at any previous period — but because other values seem to have been sacrificed and because they seem to have been sacrificed unnecessarily, inasmuch

London Bridge station has been shortlisted for the Riba Stirling architects prize. The jury said its “impressive” new concourse had “significantly improved the experience of those who use it daily”. That’s nonsense, says The Spectator’s Wiki Man, Rory Sutherland: In the shadow of the Shard, not far from Borough Market, is a £1 billion public artwork,
‘Suppose you bought a case of claret a few years ago for £20 a bottle. It now sells at auction for about £75. You have decided to drink a bottle. Which of the following best captures your feeling of the cost to you of drinking the bottle? 1. £0. I already paid for it.
I was talking to a large Silicon Valley video-conferencing firm the other day. ‘Just for interest,’ I asked, ‘what would it cost to provide your service to 65 million people?’ The reason I asked is simple. I don’t understand why it is fine for government to spend £60 billion on a railway or £20 billion
