Key ideas in Everyday Cognitive Biases
- Memory searches organize by starting letters, making those words faster to retrieve
- The availability heuristic substitutes subjective ease of recall for objective probability
- Higher retrieval fluency produces an automatic illusion of greater real-world frequency
- Sensory-rich, narrative disasters trigger strong emotional salience in memory
- High-salience threats are retrieved faster, causing severe overestimation of hazard
- Common, slow-moving hazards lack emotional punch and are chronically underestimated
- Base-rate neglect occurs when descriptive stereotypes override statistical prevalence
- A vivid persona leads the mind to assess similarity rather than overall likelihood
- Even when base rates are stated, rich individual narratives suppress their influence
- Debiasing starts by identifying the objective reference class rate before seeing narrative details
- Anchoring explicitly to the statistical base rate prevents emotional overreaction
- Specific case details should only serve as secondary, incremental adjustments to the baseline
- Prospect theory finds psychological losses feel roughly twice as painful as equal gains feel pleasant.
- Because of this ~2:1 loss aversion ratio, a 50/50 gamble requires double the upside to feel acceptable.
- Near the breakeven reference point, the value function is significantly steeper for losses than gains.
- Escalation of commitment is driven by self-justification and the desire to protect personal ego.
