This document discusses several theories of deviance. It defines deviance as violating social norms and norms as rules that guide society. The structural strain theory explains deviance as resulting from social strains caused by an imbalance between cultural goals and means of achieving them. Labeling theory states that deviance is a social process where some label others as deviant. Differential association theory argues that the environment determines which norms people learn to violate through socializing agents like family and friends.
