Daniel Kahneman

Thinking, Fast and Slow



Thinking, Fast and Slow is a book about psychology which focuses on behavioural science. The sections of the book can be split up into cognitive biases, prospect theory and happiness. There’s a lot covered and it’s based on research that Kahneman carried out across his career, with some parts in collaboration with Amos Tversky.

I read this book quite a while so I’m not sure how well I can remember it. I think it was the first time I was properly introduced to various biases and heuristics. For instance, System 1 and System 2 thinking which helped me to be more aware of the way I operate in everyday life. Other notable parts I remember were the explanations on decision theory and the idea of the ‘regression to the mean’ being pretty much everywhere.

I think I might re-read this book at some point as it’s always good to remind yourself about how irrational you are as a human and then hopefully take some steps to lessen that fact. I highly recommend it to anyone interested in human behaviour and despite some bits being technical it’s overall a really well written book.
