Decoding Everyday Psychology

For the part of you with thirty open tabs that never became anything.
A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through The Traps of Individual Judgment and The Pull of Social Context. It assumes you already know the basics.

Key ideas in Decoding Everyday Psychology
- Arbitrary starting numbers skew estimates even when recognized as random.
- Anchors selectively activate memories and evidence that match the target value.
- Adjustment usually halts prematurely at the nearest boundary of plausibility.
- Vivid or emotionally traumatic events are retrieved far faster from memory.
- Ease of mental recall is subconsciously substituted for actual statistical frequency.
- Salient media coverage inflates subjective hazard risk over baseline probability.
- A diagnostic test's accuracy cannot be interpreted without the population base rate.
- Rare conditions generate far more aggregate false positives than true positives.
- Bayesian updating requires weighing test sensitivity against prior prevalence.
- Framing shifts the neutral reference point without changing the objective payoff.
- Prospect theory shows people avoid risk when facing gains but seek risk in losses.
- Evaluation rubrics must be finalized before reviewing candidate attributes.
- Weighting criteria in advance stops evaluators from tailoring metrics to favorites.
- Blinding identifiers removes social cues that trigger unconscious shortcuts.
- High personal sacrifice creates dissonance if the prize feels mediocre
- People inflate an outcome's perceived value to rationalize the pain spent
