In 1955, a University of Minnesota researcher did a simple experiment. He asked people on a beach to watch a stranger's belongings.
When no commitment was asked, only 20% intervened if someone tried to steal. When they verbally committed, 95% intervened.
Public commitment changes behavior.
Why it works
We have a deep desire to be consistent with what we've declared.
When you publicly say "I'm going to do X," your brain works to make your behavior match your words.
Levels of commitment
Not all commitments are equal. The more public and specific, the more effective:
Thinking it < Writing it < Telling someone < Publishing it < Doing it with someone
How to use public commitment
1. Find a habit partner.
2. Report regularly. One declaration isn't enough. Weekly progress reports maintain positive pressure.
3. Be specific.
4. Add consequences.
Who will you tell what you're trying to do?
