One of the most influential books of the 21st century: the ground-breaking psychology classic - over 10 million copies sold - that changed the way we think about thinking 'There have been many good books on human rationality and irrationality, but only one masterpiece. That masterpiece is Thinking, Fast and Slow ' Financial Times 'Will be remembered hundreds of years from now' David Brooks, The New York Times Why do we make the decisions we do? Nobel Prize winner Daniel Kahneman revolutionised our understanding of human behaviour with Thinking, Fast and Slow . Distilling his life's work, Kahneman showed that there are two ways we make choices: fast, intuitive thinking, and slow, rational thinking. His book reveals how our minds are tripped up by error, bias and prejudice (even when we think we are being logical) and gives practical techniques that enable us all to improve our decision-making. This profound exploration of the marvels and limitations of the human mind has had a lasting impact on how we see ourselves. 'Stunningly profound... A lifetime's worth of wisdom presented in a manner that is simple and engaging' Steven D. Levitt, author of Freakonomics
