The charge

Bandwagon effect is adopting a belief or behavior because many other people appear to hold it.


How it operates

Social proof and fear of being left behind substitute for independent evaluation.

Logged incidents

  2. Incident 02

    Investors pile into a hot theme after others already did.

  3. Incident 03

What to watch for

Recommended action
