Thinking, Fast and Slow is a renowned book that has changed behavioural psychology literature. The author of the book is Nobel laureate Daniel Kahneman. The book is divided into two parts: System 1 and System 2.
In System 1, the author talks about fast thinking, this is quick, automatic, and mainly subconscious mode thinking. It works effortlessly and is usable for our quick reactions, feelings, and actions. For example, when we see a snake, our instinctive response would be to get away from it for our safety.
In System 2, Daniel Kahneman talks about slow thinking. System 2 focuses on analytical side of our thinking process. It needs more attention, conscious effort, and critical thinking. One has to do a deeper analysis to think about something properly. On the other hand, people can feel lazy in System 2 because it takes effort to focus on anything.
Thinking, Fast and Slow is a masterpiece for those who wish to understand the intricacies of human thought and behaviour. Kahneman’s research on the dual systems of thinking shows the complexities behind our decisions and stresses the importance of critical thinking in life.
