In 'Talking to Strangers,' Malcolm Gladwell explores why our interactions with people we don't know often go so wrong. He uses fascinating real-life stories, from spies to courtroom dramas, to show that our instincts about strangers are surprisingly unreliable. The book reveals that we are often terrible at detecting lies, understanding others' intentions, and seeing the truth. Gladwell argues that to communicate better, we need to understand the hidden psychological forces that shape every encounter.
