Pscycology of persuasion

Few months ago, I completed a book recommended by charlie munger- PSYCHOLOGY OF PERSUASION. As mentioned by the title, it is a book that described the factors that influenced one's decision. This book is like a spear and a shield in one. Why do I say so? You can actually use the factors in the book to influence someone to follow your will and use it to defend against weasels who might use it to harm you.

The factors are as listed
1. Scarcity
2. Liking
3. Reciprocation
4. Authority
5. Social proof
6. Commitment and consistency

Suffice to say, these factors can affect your decisions substantially. Hence, you must always be aware of these factors that may affect your decision.
