What is the bystander effect? Read the full idea →Dozens walk past, each assuming someone else has already called for help.
On a big team everyone assumes another member will handle it, and the task slips.
A request sent to twenty people gets answered by no one; sent to one person, it gets done.
Thousands watch and stay silent, each feeling it isn't their place to step in.
'You in the red jacket — call 911' breaks the spell. Assign the responsibility and action follows.
That's just how memory works. Lock the bystander effect in with a 5-minute active-recall session — spaced repetition, no signup.
