Answer:
Primary deviance is when an individual commits a socially unacceptable act for the first time. This type of deviance is often seen as a one-time occurrence and is not expected to continue. Secondary deviance, on the other hand, is when an individual's initial deviant act is followed by further deviant behavior and the individual is seen as a repeat offender. This type of deviance is often seen as more serious and is viewed as a pattern of behavior. Secondary deviance is also more likely to lead to serious consequences for an individual, such as imprisonment or social sanctions. In both types of deviance, the individual has deviated from the established social norms, but the long-term consequences of their behavior may vary.
