Why Doesn't Anyone Help in a Crowd?

Catherine Sanderson dismantles the frozen subway car moment with sixty years of evidence, from John Darley and Bibb Latané's smoke-filled room to Richard Philpot's security-camera analysis of two hundred real conflicts. Two mechanisms lock crowds in place: diffusion of responsibility splits the burden until no one's share feels large enough, while pluralistic ignorance makes everyone read false calm from everyone else. Yet Philpot's footage shows someone intervenes nine times out of ten. The real question: why shouldn't that someone be you?

You'll learn:

- How addressing one person defeats responsibility diffusion

- Why the first to move grants permission to the crowd

- What breaks pluralistic ignorance before it sets in
