Nobel prize winner Daniel Kahneman on the irrationality of our financial system – and the difficulty of fixing it

Daniel Kahneman is a very modest man — amazingly so for someone who has won the Nobel prize in economics. When I met him in the lobby of a London hotel, he never used his very great intelligence in the way that some very distinguished economists do, to bully or to intimidate. ‘But then I am not an economist,’ he says with a mischievous smile. ‘I am a psychologist.’

Prof. Kahneman smiles a great deal. His eyes sparkle behind his large spectacles. His cheeriness is infectious, but it is also disconcerting, given that he is not optimistic about humankind. He thinks, for instance, that it will be ‘miraculous’ if we manage to do anything to stop global warming. ‘Let’s suppose that the scientific consensus is correct: global warming is happening, and it will have some catastrophic consequences. By the time it becomes obvious to everyone that it’s a danger, it will probably be too late to do anything that will be effective in combating it. As a species, our brains have just not evolved to deal with threats whose effects will be felt in what, for us, counts as the remote future. We respond to them by ignoring them.’

But surely, I protest, if global warming is really happening, we can be persuaded by reasons and arguments to take it seriously, and to do what’s necessary now to diminish the effects that will come later? Kahneman smiles indulgently. Those eyes sparkle. ‘The way scientists try to convince people is hopeless,’ he states with a broad grin, ‘because they present evidence, figures, tables, arguments, and so on. But that’s not how to convince people. People aren’t convinced by arguments. They don’t believe conclusions because they believe in the arguments that they read in favour of them. They’re convinced because they read or hear the conclusions coming from people they trust.
