Final answer:
The Labeling theory, also known as the societal-reaction approach, explains why some people are seen as deviants based on society's reaction and labels.
Step-by-step explanation:
The theory that is also called the societal-reaction approach and attempts to explain why certain people are viewed as deviants, while others with similar behavior are not seen in such harsh terms, is known as the Labeling theory. This theory falls under the paradigm of symbolic interactionism and highlights how societal reactions contribute to the labeling of an individual as deviant. The Labeling theory posits that deviance is not inherent in any act but is instead the result of the labels attached to it by society. Behaviors become deviant through the reaction and label society gives, and over time, those labeled as deviant may internalize this label and further fulfill the expectations of that label.
