Aggression will be less likely, if the person realizes that sort of behavior may not be in his best interest. Aggression, in general, might be reduced by less TV violence, parents taking the time to watch the violent shows with their children, and modeling of alternate solutions to aggression. Social norms are the standards of expected behavior that are learned when people observe a pattern of uniform behavior among a group and the negative consequences that come from deviation from the behavior. Conformity occurs when people adopt behavior and opinions to outwardly match those of a group. Conformity occurs because of the informational influence, which is the desire to be correct and to understand the right way to act in a given situation, and the normative influence, which is the desire to be liked and accepted by others.
Compliance is a behavior change that results from direct or indirect request.
Obedience occurs when people follow a direct command. A famous experiment conducted by Stanley Milgram showed the surprising lengths to which people will obey. People are more attracted to friends and romantic partners who are perceived as physically attractive. Some suggest this is a tendency engrained by evolution, since attractiveness is associated with fertility. Others suggest that it is due to reinforcements.
