Pratfall effect
In social psychology, the pratfall effect is the tendency for a person's likability to change after making a mistake depending on perceived competence: highly competent individuals tend to become more likable, while average individuals may become less likable for the same error. Originally described in 1966 by Elliot Aronson, numerous studies have since been conducted to isolate the effects of gender, self-esteem, and blunder severity on change in appeal and likability.
