Social Proof and Reputational Pressure
People may use others' behavior as information when a situation is uncertain.
The Mechanism: Social proof describes the use of others' actions as cues about what is appropriate or likely to be true. Reputational pressure can reinforce imitation, but this is not a specific canonical law proposed by Dunbar.
The Philosophical Pivot: Consensus can provide useful information when no one has a complete view. It can also hide private disagreement when people assume everyone else genuinely agrees.
The Horizon: Online metrics make popularity visible and can turn group behavior into a shortcut for deciding what deserves attention. Visibility may amplify a belief without increasing its accuracy.
Humans copy others for many reasons, including learning, belonging, and coordination. Treating every act of conformity as irrational misses the social risks of dissent.
A crowd can be informative, but it cannot take responsibility for an individual's judgment.
Consensus is evidence about what people do, not proof that they are right.
When I follow the group, am I learning from others or avoiding the social cost of disagreeing?
