1.✅Decisions made quickly can be as good (and often even better) than decisions made after thorough and deliberate thinking process.

1. We are not aware of the processes that result in quick decisions (or first impressions). 3.✅To make quick decisions, we judge a book by its cover. ❌ This process is referred to as “thin-slicing” – using a limited amount of information received over a limited period of time to come up with a decision.
2. Stereotypes, both conscious and subconscious, dislikes and likes, as well as prejudices, impede our ability to thin-slice. 👉🏻 example of it is the Warren Harding error, which basically means judging people by their appearance.
   1. What we think we like or dislike and what we actually like or dislike are often different.
3. Blink can help readers understand when thin-slicing is useful and when analytical thinking should be relied on instead.
4. This book also warns about the dangers of rapid cognition in highly stressful situations.
5. Overall, this popular science work conveys the idea that snap judgments can be learned, practiced, and controlled for more effective decision making.
