Informational Social Influence

What it is

Shaping someone's beliefs by positioning group consensus as evidence that something is true.

How it works

When people are uncertain, they look to others for information about reality. If a group appears to believe something, individuals internalize that belief — not just publicly, but privately. Manipulators exploit this by manufacturing the appearance of consensus or expertise agreement.

Real-world examples

  • •Astroturfing campaigns that create fake grassroots support to make a position seem widely held.
  • •Review manipulation where fake positive reviews make a product seem genuinely well-regarded.
  • •Authoritarian regimes staging public rallies to create the impression of widespread support.

Ethical guidelines

  • ●Do not fabricate the appearance of agreement or widespread belief.
  • ●Present genuine evidence rather than relying on "everyone thinks so."
  • ●Differentiate between actual expert consensus and manufactured consensus.

How to defend against it

  • ►Verify whether an apparent consensus is genuine by checking diverse, independent sources.
  • ►Ask for evidence beyond "most people believe this" — popularity is not proof.
  • ►Be especially cautious of consensus claims on the internet where bot and shill activity is common.
