Six “Weapons of Influence”

Cialdini defines six “weapons of influence”:

* Reciprocation - People tend to return a favor.
* Commitment and Consistency - If people commit, verbally or in writing, to an idea or goal, they are more likely to honor that commitment.
* Social Proof - People will do things that they see other people are doing.
* Authority - People will tend to obey authority figures, even if they are asked to perform objectionable acts.
* Liking - People are easily persuaded by other people that they like.
* Scarcity - Perceived scarcity will generate demand.
