Insight by Psychology

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

Children born earlier in a cutoff-based youth sports cohort gain long-term advantages because being older on average makes them bigger and faster, which attracts more playing time, tournaments, and better coaching that compound into elite-selection biases.

Positional authority (like a boss) can backfire because it feels coercive and breeds resentment when oversight is absent, whereas credible authority (expertise plus trustworthiness) persuades by providing useful information people adopt even without monitoring.

Gossip makes people less likely to listen to you because speaking ill of someone signals you betray confidence, which causes listeners to distrust you and avoid engaging.

Giving benefits or useful information first increases compliance because receiving a favor creates a felt obligation to reciprocate, which makes people more ready to say yes to later requests.

When applicant pools are large relative to available slots, small amounts of luck matter more because random variation can shift rankings just enough that minor luck differences determine who enters the selected group.

Researchers systematically overestimate between‑subject manipulation strength because they mentally simulate both conditions (a within‑subject perspective), which makes effects feel larger than they appear to participants who experience only one condition.

Admitting luck in your success increases perceived kindness because acknowledging external help signals humility and social awareness, which makes observers view you as more likable and trustworthy.
