Thinking, Fast And Slow


Thinking, Fast and Slow is a 2011 book by psychologist Daniel Kahneman.The book's main thesis is a differentiation between two modes of thought: "System 1" is fast, instinctive and emotional; "System 2" is slower, more deliberative, and more logical.




Thinking, Fast and Slow



Don't feel bad if that problem stumped you. It's designed to exploit gaps in System 1 thinking. By drawing your eye to the quick succession of 5s, you naturally look to make the same connection in the solution. It's only through the slower, more deliberate thinking involved with System 2 that brings the correct answer into focus.


Scientists love to divide human thinking into two parts: right brain vs. left brain, rational vs. emotional, conscious vs. subconscious, and no doubt many others. Daniel Kahneman, Nobel Prize winner in Economics, proposes a simple split to explain much of human behavior: fast vs. slow. He makes it clear that this is an artificial construct, but at the same time draws upon decades of research to demonstrate its utility.


You have to be both, slow and aware when making the big decisions but being impulsive and quick witted is what makes life interesting when its not a do or die situation. Sounds like a great read. Nice review as well, by the way.


"Those are instances of very fast thinking," Kahneman says. "It's the same process of recognizing things and distinguishing the familiar from the unfamiliar. You're coming up with solutions that have worked in the past, that's what's called expert intuition. All these are examples of fast System 1 thinking."


For visualization, consider an experiment that recorded people's memories of a painful colonoscopy. Before the endoscopy, people were divided into two groups: one group had a very long colonoscopy, while the other group had a faster endoscopy, but the pain gradually increased at the end.


Thinking fast and slow shows us that our mind is composed of two systems. System 1 works instinctively and requires very little effort; System 2 works more meticulously and requires more concentration. Our thoughts and actions change depending on which system is controlling the brain at the time. 041b061a72
