daniel kahneman thinking fast and slow summary

Kahneman then expands this into the context of behavioral economics, arguing that our financial and practical decision making isn't as rational as economists previously thought. We also have difficulty thinking statistically, we have to tone down our liking for hindsight and become more aware of how overconfidence creates a sense of certainty where none exists. He explores these flaws in our thinking, such as our biases, anchors, and heuristics (the thumb-suck we often do when making decisions). Kahneman believes that these errors are not caused by the intrusion of emotion but by glitches in our cognitive design. However, it isn't always available or inclined to do so.īoth systems are remarkable, with unique capabilities. System 2 has to bring self-control to the more impulsive, continuously active workings of System 1. While we may think that System 2 is where we spend most of our time, our story's main character is System 1.

The first is automatic, and the second is effortful. System 2 on the other hand, is slower, deliberate and logical, and needs more concentration. System 1 is fast and emotional, and requires minimal effort and no voluntary control. He is at pains to point out that they do not have an actual 'home' in the brain, but are just nicknames that give us a language to understand both our intuitive and deliberate ways of thinking, how we use them together, and how they influence our choices. He calls these the 'fictitious characters' of our minds, which govern our judgment and decision making. The central theme of the book is around what Kahneman terms our System 1 and System 2 thinking.

So if you're interested in behavioral economics and cognition, or want to engage your slower, more rational self to make better decisions, you'll find this an interesting and insightful read. Kahneman argues that our rational minds fall prey to subtle irrationality without us even realizing it, and errors trip us up even when we think that we're logical. It's an insight into the less-than-perfect performance of the rational mind, that we can use to identify mental glitches that get us into trouble.Ī large part of Kahneman's research was done collaboratively with his colleague Amos Nathan Tversky, who passed away in 1996, and to whom he dedicates the book. World-famous psychologist and Nobel Prize recipient Daniel Kahneman, summarizes decades of research on thought and decision making. Thinking, Fast and Slow should be read slowly.
