- System 1 replaces a hard target question with an easier heuristic question automatically.
- The mind rates actual probability based on the cognitive ease of emotional retrieval.
- Anchoring operates by activating compatible features in associative memory.
- Selective accessibility primes the brain to look for evidence confirming the anchor.
- Passive awareness cannot undo automatic semantic priming in associative memory.
- Breaking an anchor requires actively generating reasons why that number is inappropriate.
- The peak-end rule averages the emotional climax and the final moment of an event.
- Retrospective evaluations exhibit duration neglect by ignoring the overall time elapsed.

- Overriding a preset default requires actively expending cognitive effort.
- Opting out frames the change as a loss or an active personal deviation from the norm.
