The Pratfall Effect :
In social psychology, the pratfall effect is the tendency for attractiveness to increase or decrease after an individual makes a mistake, depending on the individual’s perceived competence, or ability to perform well in a general sense. A perceived competent individual would be, on average, more likable after committing a blunder, while the opposite would occur if a perceived average person makes a mistake.
Effects of pratfall are most directly applicable to males. Women tend to prefer the non-blunderer regardless of gender, and although findings of pratfall cannot be readily generalized to female populations, neither population preferred the mediocre blunderer.
We tend to like people who make mistakes more :
Apparently, making mistakes actually makes us more likeable, due to something called “The Pratfall Effect”.
Those who never make mistakes are perceived as less likeable than those who commit the occasional faux pas. Messing up draws people closer to you, makes you more human.
This theory was tested by psychologist Elliot Aronson. In his test, he asked participants to listen to recordings of people answering a quiz. Select recordings included the sound of the person knocking over a cup of coffee. When participants were asked to rate the quizzers on likability, the coffee-spill group came out on top.
Experimental data suggests the pratfall effect is best explained by self-comparison between blunderers and observers in addition to the observer’s desires for accurate self-evaluations.
