Behavioral confirmation

Behavioral confirmation is a type of self-fulfilling prophecy whereby people's social expectations lead them to behave in ways that cause others to confirm their expectations. The phenomenon of belief creating reality is known by several names in literature: self-fulfilling prophecy, expectancy confirmation, and behavioral confirmation, which was first coined by social psychologist Mark Snyder in 1984. Snyder preferred this term because it emphasizes that it is the target's actual behavior that confirms the perceiver's beliefs.

Preconceived beliefs and expectations are used by human beings when they interact with others, as guides to action. Their actions may then guide the interacting partner to behave in a way that confirms the individual's initial beliefs. The self-fulfilling prophecy is essentially the idea that beliefs and expectations can and do create their own reality. Sociologist Robert K. Merton defined a self-fulfilling prophecy as, in the beginning, a false definition of the situation evoking a new behavior which makes the originally false conception come true.

Self-fulfilling prophecy focuses on the behavior of the perceiver in electing expected behavior from the target, whereas behavioral confirmation focuses on the role of the target's behavior in confirming the perceiver's beliefs.

Research has shown that a person (referred to as a perceiver) who possesses beliefs about another person (referred to as a target) will often act on these beliefs in ways that lead the target to actually behave in ways that confirm the perceiver's original beliefs.

In one demonstration of behavioral confirmation in social interaction, Snyder and colleagues had previously unacquainted male and female partners get acquainted through a telephone-like intercom system. The male participants were referred to as the perceivers, and the female participants were referred to as the targets. Prior to their conversations, the experimenter gave the male participants a Polaroid picture and led them to believe that it depicted their female partners. The male participants were unaware that, in fact, the pictures were not of their partners. The experimenter gave the perceivers pictures which portrayed either physically attractive or physically unattractive women in order to activate the perceiver's stereotypes that they may possess concerning attractive and unattractive people. The perceiver-target dyads engaged in a 10-minute, unstructured conversation, which was initiated by the perceivers. Individuals, identified as the raters, listened in on only the targets' contributions to the conversations and rated their impressions of the targets. Results showed that targets whose partners believed them to be physically attractive came to behave in a more sociable, warm, and outgoing manner than targets whose partners believed them to be physically unattractive. Consequently, targets behaviorally confirmed the perceivers' beliefs, thus turning the perceivers' beliefs into self-fulfilling prophecies. The study also supported and displayed the physical attractiveness stereotype.
