The psychologist and Nobel Prize winner in economics Daniel Kahneman died recently. Kahneman had a huge impact on how we at K&A understand human behaviour. And thus on how we can clear up the big say-do gap between what people tell us they will do and how they actually behave. Kahneman's death reminded me once again of his last important book, Noise, and in this BrainCandy I share with you the most important insights I gained from the book.
