This is a wonderful book. The basic premise is that the human brain has evolved from an animal brain by adding the cerebral cortex (the 'rational' bit) to the pre-existing brain. We now have two 'systems' the quick intuitive from the underlying brain, and the slower, reasoning capacity from the human part of the brain. As Kahneman amply and elegantly demonstrates, we use the intuitive part of our brain much more than we realise, and that the reasoning part is lazy, and used much less than we would otherwise imagine. The result is usually fine - when a leopard is leaping out of a tree at you, you don't want to be carefully, and slowly, analysing the prospects of the threat being an optical illusion. However, and this is where Kahneman is so good in his original thinking, his experiments, and his written explanations, there are many instances in modern life and as homo economicus, that the quick and dirty response may not be so good. And, probably more importantly, the economic theory based on rational economic choices is thus baseless.He has much more in this book - which I will go back and re-read.A wonderful book, by a gifted writer and original thinker.Read July 2012

I have never read a book so densely packed with wisdom and insight. Thought-provoking on every page (even more so than Jonathan Haidt's recent work, which is referenced within), this really is a book to savour and take your time over. Particularly useful for anyone who has ever striven to make a good decision, this book takes a two-system view of the mind and uses it to explain the everyday processes of thought, how the non-analytic can impact our decisions, and what (little) can be done to reduce our biases and omissions. Reading this book will make you a better thinker, without a doubt.

An extraordinarily rich and generous summary of the results of a remarkable lifetime of investigating the way that we humans actually think.

This isn’t a standard pop science book. From the cover and title you could be fooled into thinking it is, but ultimately it’s far deeper reaching and better evidenced than anything from Malcolm Gladwell or the Freakonomics team. Deeper but equally as accessible, assuming depth doesn’t put you off.The title’s a tad deceptive as Kahnemann admits up front – the fast and slow systems of our mind he posits are a simply a metaphor to aid understanding. It’s also actually a far wider examination than simply ‘how we think’. What it does do is look at ‘fast’ thinking (what we might term intuition) and how it can lead us into tricking ourselves thanks to conscious or unconscious biases, and also how our deeper thinking mind interacts with that. By the end you’ll be wondering exactly how rational any of us are (answer: none of us are very rational, even at the best of times). And it’s always amusing to see the economic mantra of people always being rational undermined, even before ‘information asymmetry’ is taken into account.Eye-opening, but be prepared for this one to take plenty of time to read and absorb.
