Thinking Fast and Slow is definitely worth reading if you have an interest in psychology, and how and why we make decisions. The scientific studies are highly engaging and Kahneman’s theories apply to a range of well-known human behaviors. This includes the sunk cost fallacy, risk aversion, and why first impressions count. If you’re looking for a ‘how to’, you might be disappointed. The crux of the book is that we can’t control the underlying fast thinking process. But we can learn to recognize when our slow thinking is being led astray.
