Corroborating Evidence

Corroborating evidence is crucial when it comes to changing minds and opinions. People try to make sense of recommendations and translate them to see if they are informative or diagnostic. When multiple sources say or do the same thing, it adds credibility, legitimacy, and reinforcement.

The more similar these sources are to the individual, the greater the impact. Concentrating proof in a short period boosts its effectiveness, and spreading out recommendations can mute their effect. When trying to change minds, it’s important to consider who, when, and how the corroborating evidence is presented.
