Daniel Kahneman

There are three sides to every story

From our UK edition

The psychologist Daniel Kahneman, who died last month aged 90, was perhaps most famous for his dictum that: ‘Nothing in life is as important as you think it is when you are thinking about it.’ This is often known as the focusing illusion. The theory explains, say, why a recent Lottery winner with bad toothache may, in the moment, be little happier than a skint person with bad toothache, since in both cases their attention is focused on the pain, not their financial situation. When Trump rails about ‘fake news’, I suspect this resonates with voters much more than journalists actually realise It is an important bias to understand, not least because it gives us a vital and often overlooked insight into media bias.
