Bandwagon: how it works

The bandwagon technique persuades by suggesting that everyone, or everyone like you, is already on board. It is one of the seven propaganda devices popularised by the Institute for Propaganda Analysis in the late 1930s, and it is still taught as a way to read advertising critically.

How to spot it

  • Crowds, popularity claims, "join millions" language or a sense of a movement.
  • Campaigns built so that taking part is itself the message, and the number of people taking part becomes the proof.
  • A phrase or ritual that spreads because people want to be part of it.

Why it works

People look to others when deciding what to do, especially when they are unsure. Modern campaigns often go further than claiming popularity: they create real participation and let the crowd become the ad.
