Resocialization is the process of discarding values and behaviors unsuited to new circumstances and replacing them with new, more appropriate values. Unsystematic resocialization involves no formal preparation. People resocialize as they go, when they remarry, change jobs, become parents, retire, and so on. A more formal kind of resocialization, called systematic resocialization, can be either voluntary or imposed. It is voluntary when people choose to participate in a process to “remake” themselves, such as enrolling in a recovery program for alcoholics, or training for a profession like medicine. Resocialization is imposed when people are forced to undergo a program designed to rehabilitate them. Prisons, mental institutions, and military boot camps are a few examples of environments where this occurs.
