Updated: Sep 3
Due to our desire to be consistent, our beliefs don't often change, even when it is not in our self-interest.

I have taken the lessons from 'Yes' and distilled them into 18 core principles:
To overcome the effects of peoples' consistency bias, avoid framing their commitment as a mistake. Tell them: "Their decision was correct at the time they made it"

There are 3 major factors that influence reciprocity: • Significant: When a waiter gave two candies with the bill it increased tips by 3.3% (compared to no candy) to 14% with 2 candies. •Unexpected: One candy was expected and so when a second was given it inflated the tip. • Personalized: The more personalized the request, the more likely the person will agree.

People are more likely to be persuaded if they have taken a small step in the right direction as long as the first step was made voluntarily and without coercion. The momentum will propel them to carry on.
Give a person the label of a certain trait and then make a request consistent to that trait (and provide examples of when they have done that).
After a person has answered a question favorably, say "I'll let the others know" to increase commitment as their decision has now been publicly declared.
Ask someone why they support an initiative. This will reinforce to themselves the reasoning.
