Blink by Malcolm Gladwell Key Ideas


Here are 5 key ideas to remember from in Blink by Malcolm Gladwell:

  1. Decisions made quickly can be as good (and often even better) than decisions made after thorough and deliberate thinking process
  2. 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
  4. Stereotypes, both conscious and subconscious, dislikes and likes, as well as prejudices, impede our ability to thin-slice. An example of it is the Warren Harding error, which basically means judging people by their appearance
  5. What we think we like or dislike and what we actually like or dislike are often different

Now that you know what the book is about, let’s proceed to the Blink Malcolm Gladwell summary chapter-by-chapter.

Blink Book Summary


In Introduction, Gladwell tells the story about J. Paul Getty Museum’s purchase of a forged statue that could have been avoided if experts would have listened to their first impression. When this statue, a Greek kouros, was first presented to the museum officials in 1983, they immediately doubted its authenticity, even though didn’t have any evidence to prove that the statue was forged.

After 14-month examinations and analysis of core samples, the statue was finally put on display 1986. A number of art experts started expressing their doubts about statue authenticity and eventually, the statue was proven to be a forgery. Gladwell refers to this example throughout the book to prove his point that the first impression is often the one we can trust.

Chapter 1

In this chapter, Gladwell focuses on explaining how thin-slicing, or rapid cognition, works in everyday life while making decisions. The author states that often have a little information about a person or situation is enough to make correct conclusions. He describes an experiment where friends and strangers were asked to evaluate students’ personality (extraversion, agreeableness, emotional stability, conscientiousness, and openness to new experiences) based on observing their dorm room. Results of this experiment demonstrated that strangers were overall better at evaluating students’ character traits than friends. Gladwell also notes that thin-slicing isn’t an exotic gift, but rather a “central part of what it means to be human.”

Chapter 2

In Chapter 2, Gladwell introduces the idea of the “locked door”, which implies that while people are good at making snap judgments, they are also bad at explaining why they are able to make them. In this part of the book, one of the key ideas is explained, in particular, that what we think we like or dislike differs from what we actually like or dislike. The author reveals that tennis coach Vic Braden could accurately predict whether a player would double fault and struggle to explain this ability of his.

Gladwell also goes into detail describing speed dating cases where people had lists of specific traits they were looking for in potential partners but ended up being attracted to someone who didn’t have those traits. Therefore, this chapter reveals that subtle environmental triggers that we aren’t aware of can form effective snap judgments.

Chapter 3

In this chapter, Gladwell changes perspective and focuses on negative effects of thin-slicing, especially the Warren Harding error. The author states that millions of Americans voted for Warren Harding because he was good-looking, while eventually, he turned out to be one of the worst presidents in history. Gladwell calls the Warren Harding error “the dark side of cognition” and states that it is a major cause of discrimination, prejudice, and stereotyping.

The author also reveals that people can detect the Warren Harding error and make efforts to fight it, trying to make unbiased decisions. In this chapter, the author also says that in one study of car dealerships indicates that black people generally received higher offers than white people, which indicates thin-slicing. Overall, this chapter suggests that thin-slicing can have various negative outcomes.

Chapter 4

This chapter focuses on the practical example of using rapid-fire decision making to increase efficiency of decisions. The author focuses the entire chapter on telling the story of Paul Van Riper, former Marine Corps commander in Vietnam, who was asked to be the ruler of the Red Team in Millenium Challenge 2002. In this war game conducted by the U.S. military, Van Riper selected leadership and decision making style that is improvisational rather than traditional Western analytical style. In addition, the Blue Team had advantages in every aspect of the game. As a result, encouraging people to make decisions based on their instincts helped Van Riper win the game. This chapter demonstrates that first impression and thin-slicing can be usefully combined with deliberate and analytical thinking and decision making.

Chapter 5

In this chapter, the author focuses on the potential of using thin-slicing in marketing. In the first example, Gladwell tells about how musician Kenna couldn’t get his breakthrough due to unsuccessful tests with test audiences, despite the approval of numerous producers. Gladwell suggests that the issue with thin-slicing here is the over-reliance of music studios on test audiences and their initial response to Kenna’s music.

In another example, the author tells how Coca-Cola launched New Coke in the 1980s that had a taste similar to Pepsi because Pepsi had a better response than Coke during blind taste tests. However, as Gladwell states in the chapter, consumers usually don’t drink Coke blind, but instead get their experience from a variety of factors other than taste. Therefore, expert opinions are necessary to explain quick decisions.

Chapter 6

In this chapter, the author focuses on the different aspects of thin-slicing in high-stress situations. Gladwell states that in such situations, people have heightened sensitivity, which increases the risk of thin-slicing going wrong. To illustrate this point, the author refers to the tragic incident in 1999, when African immigrant Amadou Diallo was shot by the NYC police. In this situation, policemen presumed he was trying to pull a gun out of his pocket, while in fact, he was trying to get his wallet. Gladwell states that “mind-blindness” is caused by extreme arousal and isn’t inevitable, however it is an example of how thin-slicing can distort the perception of the situation.


In final paragraphs, Gladwell illustrates how thin-slicing can be useful for making the most effective decisions. In particular, rapid cognition is used during auditions in classical music orchestras, which eliminates such factors as age, gender, race, and appearance, from the decision-making process. The author notes that blind auditions in National Symphony Orchestra resulted in a rapid increase in the number of female musicians. Gladwell states that some people look like they perform better due to their great posture and confidence, while others look awful when they play despite sounding great. Blind auditions take distracting factors out of the thin-slicing and allow only ears to judge.
