Adrian's Reviews > Thinking, Fast and Slow

** spoiler alert ** The book is about behaviour economics , why and how we take decisions , how we weight the good vs bad.

Main theme :
There are 2 systems at work in our brain:
- system 1 : this is the fast , auto-pilot-default , associative one , whenever you are faced with a situation your brain first uses this one and starts fetching a tree-like data structure composed of events , feelings , memories , words and tries to mold them into some sort of mosaic otherwise known as coherence so that it makes sense for you. Thats how you construct a story and you believe it.
- system 2 : is the slow , lazy and, deliberate one. This bad boy is used whenever you need to focus a large part of your attention (multiplying numbers , driving...etc)

My favourite part:
Whenever you are faced with a hard question , your system 1 answers to another simpler question and mischeviously replaces the answer so that it looks you have answered the original one:

Ex;
Bob: i placed 200 k on Ford Stocks
Fred: Why did you check their financials ?
Bob: I like ford cars and i visited the factory:


Bob is tasked with answering a tough question : does he know how Ford financials look like ?
Bob's system 1 answers to a simpler question: Do i like Ford cars ? Yes
Bob then sets the answer Yes to the original question even though he answered for the second.


Besides these 2 systems that are explained thoroughly with examples and statistics and case studies ,this book is great because it explains so much more regarding human behaviour in making decisions like : the law of small mumbers , priming , framing , utility and prospect theory , regression , planning fallacy and so much more.

Even though the book is terrific on theory and examples on why things happen the eay they are i rated it with 4/5 because i did feel like i wanted a section dedicated to "how to avoid X or Y "

All in all good terrific read !
