Its a book on behavioral psychology by a nobel prize winning economist, and I think it puts all other psychology books to shame.
here is a summary of it: http://sivers.org/book/ThinkingFastAndSlow
A Summary Is A Near-worthless Substitute
Spending additional effort to gain greater understanding of this book is a necessary first step to integrating what it is teaching. This is because integrating facts about behavioral psychology into one’s currently existing mental models is difficult. It is more difficult when the facts are not in line with a more foundational belief that we hold (about ourselves, or people in general). For example: the diffusion of responsibility in an emergency. Therefor, these facts need to be reinforced with experiencing the experiment, as well as stories of the experiences of others. Without these reinforcements, we tend to not integrate these facts of human tendencies into our existing models. This is why teaching psychology is difficult. It is also why a summary of Thinking, Fast and Slow is in no way a comparison to the experience of reading the book itself.
a proposal for reading it more effectively:
auditory and visual working memory are to some extent separate. Effective working memory can therefor be increased by using both processors at the same time.
the depth of intelligence is proportional to the ability to transfer information from working memory to long-term memory. However moving information from short-term to long-term is a major bottleneck in our brain.
“Thinking Fast and Slow” is long, and requires energy. To decrease the energy needed to read it, and increase both the retention and probability of finishing, I recommend reading a physical copy while listening to an audio copy. I think the knowledge it contains is well worth the financial investment of $43 ($33 on audible. $10 for hardcopy on amazon).
