Not really... People are allowed to hold on to false claims.

Everyone simply has to live with their claims and suffer/benefit from the effects on their integrity & credibility.

Human nature seems to motivate people to find others that are "suffering" from the same false claims so they can "suffer" together. Seems it would be better to examine the validity of what is being claimed, but that might just be me.

In big words: "Cognitive Dissonance". In layman's terms: "Birds of a feather".
