Key ideas in Everyday Psychology in Action
- System 1 operates automatically with minimal effort, relying on vividness and gut heuristics
- System 2 requires deliberate mental energy, which depletes rapidly under stress or fatigue
- When cognitive resources drain, intuitive System 1 heuristics override deliberative choices
- Default options exploit human inertia because accepting the pre-selected option costs zero mental effort
- Opt-out framing implicitly signals a socially recommended norm to uncertain decision-makers
- Switching away from a preset default requires active friction, planning, and deliberate effort
- The compromise effect makes middle options appear safe and sensible compared to extreme choices
- Asymmetric dominance uses a decoy that is strictly inferior to one option to make that target look superior
- Adding a decoy alters the perceived value of existing options without improving their actual merits
- Large assortments attract attention but trigger decision paralysis, reducing overall purchase rates
- Excessive options force complex trade-offs, which increases counterfactual thinking and post-purchase regret
- Comparing too many nuanced attributes exhausts cognitive bandwidth and diminishes satisfaction
- Memory actively rebuilds events upon retrieval rather than replaying an indelible recording
- Leading post-event language introduces misinformation that integrates directly into personal recollections
- Irreversible actions create uncomfortable psychological tension when the outcome is disappointing
- Spreading of alternatives shifts preferences so chosen options seem superior, justifying the past sacrifice
