 Informal controls reward or punish acceptable or unacceptable behavior (i.e., deviance) and are varied from individual to individual, group to group, and society to society.For example, at a Women's Institute meeting, a disapproving look might convey the message that it is inappropriate to flirt with the minister.In a criminal gang, on the other hand, a stronger sanction applies in the case of someone threatening to inform to the police of illegal activity.
