Daniel Kahneman: Thinking, fast and slow

This is a clip from an episode of Health Check.

In a programme from 2012, Claudia Hammond interviews the Nobel Prize-winning psychologist Daniel Kahneman.

He's someone whose work has really made her stop and think over the years.

He could ask you a question which sounds easy, but inevitably you get the answer wrong, revealing the common mistakes which a lot of us make systematically in everyday thinking - mistakes which can lead us to make some very poor decisions.

Although he was a psychologist, Professor Kahneman was awarded the Nobel Prize for economics for his work with Amos Tversky, which called into question the economists' assumption that we're all selfish, rational and logical.

His book Thinking, Fast and Slow covers his 45 years of work in this area.

He spoke to Claudia about the two kinds of thinking he identifies – system one which is fast, automatic and emotional and system two which is slower and more logical.
