Philip Zimbardo

Good people, powerful situations

A psychologist who studied how situations and roles can reshape human behavior.

Situations can have a more powerful influence over our behavior than most people appreciate.
— Philip Zimbardo

Who they were

Philip Zimbardo became known for the Stanford Prison Experiment, in which students assigned to play guards and prisoners slipped alarmingly fast into their roles. He argued that behavior is shaped less by fixed character than by the situations and systems people are placed within. Later in life he turned the same lens toward the good, studying shyness, time perspective, and what he called everyday heroism. His career traced a single thread: understanding how circumstance can corrupt, and how it might also ennoble.

Their big idea

Situationism

Philip Zimbardo argued that circumstances, roles, and settings shape conduct more powerfully than character alone, as his prison study suggested when good people slipped into cruelty. He later turned the same lens toward heroism, asking how the right situation can call out our better selves.
