Blinks builds on research in psychology and behavioral studies, to dissect what happens when we make decisions. The author describes the main subject of his book as “thin-slicing”: our ability to gauge what is really important from a very narrow period of experience. This is an idea that spontaneous decisions are often as good as or even better than carefully planned and considered ones.
Gladwell also mentions that sometimes having too much information can interfere with the accuracy of a judgment, or a doctor’s diagnosis. This is commonly called “Analysis paralysis”. The challenge is to sift through and focus on only the most critical information to make a decision.
After reading this book you also realize that a lot of the time when you are struggling with a hard decision, you have actually already made the call, and are just trying to come up with a rational explanation to justify it. If you use this to your advantage, you can often remove a lot of time from decision processes by simply trusting yourself and knowing that there probably are a bunch of reasons why you lean towards one or the other thing.
