— about the book —

description: by publisher

The best selling book Thinking: Fast and Slow is written by Daniel Kahneman PhD — a well known researcher in the fields of behavioral economics + psychology and winner of the 2002 Nobel Prize in Economic Sciences.

The book takes readers on a journey of exploration: what influences human thinking and our choices? Kahneman says that people have too much confidence in their ability to have good judgment. So we need to understand what hidden human behaviors affect our decision-making.

Kahneman’s theory of two types of human thinking are called:

system 1 — fast thinking
system 2 — slow thinking

He explains the psychology behind things people imagine that we understand, but we really don’t — like the concept of intuition.

The book’s careful research into the science of how people think helps explain how we make choices in life. Thinking: Fast and Slow gives deep insight into: the psychology of our reactions, judgment, recognition, decisions, conclusions.

The book is a summary of Kahneman’s landmark research — that he did over decades — in collaboration with his colleague Amos Tversky PhD. The book also covers the 3 phases of Kahneman’s long career:

— his research on cognitive bias
— his research on prospect theory
— his research on happiness

about | 2 systems of human thinking
Theory by Daniel Kahneman PhD from his book.

In his book, Daniel Kahneman PhD explores his theory of 2 different ways people think. He calls this system 1 + system 2. He covers a number of experiments in his book that claim to show the differences between these 2 systems, but the experiments get different results — even w. the same inputs.

The concepts are: attention, laziness, association, jumping to conclusions, choices, and WYSIATI — what you see is all there is. The system 1 vs. system 2 debate explores how people make decisions, with big impact for fields like law and advertising.
