Walter Reckless's containment theory emphasizes the importance of inner and outer controls in preventing deviant or criminal behavior. Inner containment refers to the internal controls we develop through our upbringing, such as conscience, values, and morality, which shape our self-concept as a law-abiding citizen. Outer containment involves external factors like family, friends, police, and religious authorities that reinforce societal norms. The combination of these internal and external containments dissuades individuals from deviating from social norms and committing crimes.
