๐Ÿ’Ž On the pernicious effect of “the Arithmocracy” (more specifically, the spreadsheet)

What the spreadsheet has done is to create in organisations and governments an over-reliance on numbers (by no means always meaningful or even accurate) with the result that often spurious numerical targets, metrics or values invariably override any conflicting human judgment. This has given rise to what a colleague of mine, Anthony Tasgal, calls “The Arithmocracy”: a powerful left-brained administrative caste which attaches importance only to things which can be expressed in numerical terms or on a chart.

๐Ÿ’Ž On removing anxieties about buying a product (Dr Pepper)

But weirdly, Iโ€™ve never asked for Dr Pepper in a bar because you know theyโ€™re not going to have it and thereโ€™s that mild embarrassment about asking for something they havenโ€™t got, and feeling like a bit of a twat. However, if you ask for Coke and they donโ€™t have it, itโ€™s their fault not yours, the whole dynamicโ€™s completely different. The only place that itโ€™s socially acceptable not to sell Coke is a total health farm weirdo place full of organic produce, and even then itโ€™s a bit irritating. Theyโ€™ll have loads of those Fentimans Victorian-style lemonades, and even then itโ€™s a bit irritatingโ€”come on, just sell Coke for crying out loud! Everywhere else has to sell Coke and itโ€™s their fault if they havenโ€™t got it. An aversion to little things like minor forms of embarrassment stop me from being a maximiser and asking for Dr Pepper, and Iโ€™ll always ask for Diet coke if Iโ€™m in a pub or a bar unless they have some massive sign saying โ€˜We Sell Dr Pepperโ€™, in which case I would obviously ask for Dr Pepper.

๐Ÿ’Ž On how we twist the facts to see what we want to see (personality tests)

Subjects were asked to complete a bogus personality test. The experimenter then gave them all exactly the same sketch of their personalities, which he claimed was based on their test results. When asked about the accuracy of the sketch, 90 per cent of the subjects thought it a very good or excellent description of themselves. People are so good at distorting material to fit their expectations that the identical sketch was thought by each of nearly fifty subjects to apply specifically to him or her.

In addition to trying unconsciously to confirm his or her beliefs, anyone who pays to see a fortune teller will have invested time and money: unless he has just gone for a lark, he will therefore want to feel he has got something out of it (misplaced consistency) and hence will be predisposed to believe what he hears.
