“You’ve got to have models in your head. And you’ve got to array your experience ‑ both vicarious and direct ‑ on this latticework of models.” -Charlie Munger

11 Mental Models from the book:

1. Attentional bias

2. Curiosity Instinct

3. Evolution: Natural Selection

4. Incentives

  1. Self-regard
  2. Least effort - No appeal to reason that does not also have an appeal to want can ever work. - "The trouble with many of us is that the more immediate, really less important wants absorb our attention and get our instant reaction; while the less immediate, but really more important wants are scarcely attended to.....it is more important than a man's country be secure than that he should have a particular automobile. Usually, however, it is the automobile that gets his most absorbed attention."

5. Momentum

  1. What is happening?
  2. What is going to happen?

6. Narrative Instinct

7. Novelty Bias

8. Randomness

9. Second-Order Thinking

10. Status Quo Bias

11. Vividness Bias

  1. The speed (and clarity) in which it is received.
  2. How easily it is recalled. - "All over the world" is less meaningful than "New York City". The former is too general for the listener to form a picture in their mind. Notice the vagueness of: "The Joint Committee on Methods of Preventing Juvenile Delinquency" vs "Camp Fire Girls" - If you wanted to get people to donate to starving children in Africa: Telling them it is their duty to help, not many would be moved, as they will likely become defensive. If you ask people if they would be so kind as to donate, they may be slightly moved to do so out of pity. If you flatter the person, saying that by your contribution you are helping humanity, you may be even more likely to get some help. However, if you took people to Africa and let them see the conditions and allow them to help individual children, they would likely help without any push from you. The last technique would be costly, so instead, we use the person's imagination. - What makes writing dull:

  3. Stodginess: Having no unfamiliarity in the familiar.

  4. Verbosity: Too many stimuli causing the reader to skip.
  5. Circumlocution: The stimulus never arriving causing the reader to be uncertain, impatient, irritated, and saying "get to the point".
  6. Lack of Clearness: Long sentences with ideas that are poorly arranged.
  7. Lack of Curiosity: The reader just nods but doesn't have their curiosity piqued.
  8. Abstractness: No vivid pictures are being created in the mind of the reader.
  9. Rhythm: Lack of rhythm that causes the reading to be jerky or monotone.
  10. Concrete vs Abstract: Use concrete words that create pictures in your mind.
  11. Personality: Your personality, be it humble or smart-Aleck, should shine through in your writing.
