Insight by Psychology

Country of birth explains large global income differences because national institutions, economic conditions, and resource distribution shape the opportunities available from childhood, materially raising expected lifetime earnings for those born in wealthier countries.

When constructing memories people encode sequences and salient moments more than elapsed time, so remembered narratives emphasize highlights and often omit duration when evaluating experiences.

Increasing physical or psychological distance—via artillery, remote weapons, or dehumanizing rhetoric—makes mass violence easier because it removes direct confrontation and the moral resistance that face-to-face contact normally triggers.

Framing a small current adoption as part of a fast-growing trend increases compliance because people project recent growth forward and expect future uptake, which makes them more likely to join now.

Attributing positive outcomes to your own traits reduces willingness to share rewards because internal explanations create feelings of entitlement that decrease perceived obligation to redistribute gains.

People are more likely to comply with those they like because demonstrating similarity and giving sincere, specific compliments increases liking, which raises persuasive power.

Successful people often believe the world is meritocratic because survivor bias leads them to observe only those who worked hard and succeeded, causing them to generalize that effort reliably produces success while ignoring failed but hardworking peers.

When people explain their beliefs or actions they often offer post‑hoc rationalizations because many causal mental processes operate unconsciously and are inaccessible to introspection.
