In Talking to Strangers, Malcolm Gladwell asks a deceptively simple question: why are we so bad at judging people we don’t know? Drawing on psychology, criminology, and real-world cases, he argues that humans are wired to “default to truth”—we believe others because constant suspicion would make society impossible. That trust keeps the world running, but it also leaves us open to deception and tragedy.

Gladwell shows how easily we misread cues and context—mistaking confidence for honesty or guilt for innocence. From courtroom bail decisions to espionage scandals and misjudged police encounters, he reveals how these blind spots can turn deadly. His takeaway isn’t cynicism, but humility: trust, but understand its limits.

Talking to Strangers is both caution and invitation—to slow down, question first impressions, and design systems that account for human error rather than pretend it doesn’t exist.
