In reality, our minds are riddled with biases leading to poor decision making. We ignore data that we don't see, and we weigh evidence inappropriately. Thinking, Fast and Slow is a masterful book on psychology and behavioral economics by Nobel laureate Daniel Kahneman. Learn your two systems of thinking, how you make decisions, and your greatest vulnerabilities to bad decisions.
Daniel Kahneman begins by laying out his idea of the two major cognitive systems that comprise the brain, which he calls System 1 and System 2. System 1 operates automatically, intuitively, and involuntarily. We use it to calculate simple math problems, read simple sentences, or recognize objects as belonging to a category. System 2 is responsible for thoughts and actions that require attention and deliberation: solving problems, reasoning, and concentrating. System 2 requires more effort, and thus we tend to be lazy and rely on System 1. But this causes errors, particularly because System 1 has biases and can be easily affected by various environmental stimuli called priming.
In this book, Kahneman describes the ways in which we think or make decisions — and how those ways work against and with one another. System 1 thinking is better described as our intuition, which relies on subconscious information and prior experience to make a decision. System 2 is logical and deliberate, and it requires careful consideration of reasonable information to make a decision. However, this type of thinking is also prone to excessive bias and will always look for things to confirm your suspicions. Thus, System 1 thinking can get us into big trouble or cause us to emotionally react when it is not necessary.
It was the winner of the National Academies Communication Award for best creative work that helps the public understanding of topics in behavioral science , engineering and medicine. The book summarizes research that Kahneman conducted over decades, often in collaboration with Amos Tversky. The integrity of this research has been called into question in the midst of the psychological replication crisis. The main thesis is that of a dichotomy between two modes of thought : "System 1" is fast, instinctive and emotional ; "System 2" is slower, more deliberative , and more logical. From framing choices to people's tendency to replace a difficult question with one which is easy to answer, the book summarizes several decades of research to suggest that people have too much confidence in human judgement. The book also shares many insights from Kahneman's work with the Israel Defense Forces and with the various departments and collaborators that have contributed to his education as a researcher. Kahneman describes a number of experiments which purport to examine the differences between these two thought systems and how they arrive at different results even given the same inputs.
Pick up the key ideas in the book with this quick summary. There is a compelling drama going on in our minds, a filmlike plot between two main characters with twists, dramas and tensions. These two characters are the impulsive, automatic, intuitive System 1 , and the thoughtful, deliberate, calculating System 2. As they play off against each other, their interactions determine how we think, make judgments and decisions, and act. System 1 is the part of our brain that operates intuitively and suddenly, often without our conscious control. You can experience this system at work when you hear a very loud and unexpected sound. What do you do?

Thinking, Fast and Slow provides an outline of the two most common approaches our brains utilize. Like a computer, our brain is built of systems. System 1 is fast, intuitive, and emotional. Daniel Kahneman encourages us to move away from our reliance on this system. System 1 is the most common source of mistakes and stagnation.

This is a great read for anyone who is interested in psychology and processes of thought. After studying psychology and receiving his bachelors, Kahneman was enlisted in the Israeli defence force, working primarily in the psychology department.

Writing this summary taught me how to think harder, clearer, and with fewer cognitive illusions. In short, how to think slower. Now if only I'd do it. INTRODUCTION.
