Illusion Of Truth Effect
(reading time – 40 sec.)

People are more likely to identify as true statements those they have previously heard (even if they cannot consciously remember having heard them), regardless of the actual validity of the statement. In other words, a person is more likely to believe a familiar statement than an unfamiliar one.

The truth effect plays a significant role in various fields of activity. During election campaigns, false information about a candidate, if repeated in TV commercials, can cause the public to believe it. Similarly, advertising that repeats unfounded claims about a product may boost sales because some viewers may come to think that they heard the claims from an objective source.
