Chapter 4: Behavior and Attitudes

The chapter introduces the ABCs framework distinguishing affective, behavioral, and cognitive components of attitudes, then explores the conditions under which attitudes successfully predict behavior: minimal social pressure, reduced competing influences, specificity to the particular behavior, and sufficient accessibility and stability in the attitude itself. A pivotal finding from early research showed a surprising disconnect between stated attitudes and actual conduct, leading scholars to investigate moral hypocrisy and the mechanisms underlying attitude-behavior consistency. The chapter then reverses the causal direction to examine how behavior shapes attitudes through multiple pathways. When individuals assume new social roles, engage in counterattitudinal statements without coercion, comply with escalating requests through foot-in-the-door techniques, or perform moral or immoral acts, their underlying attitudes often shift to align with their actions. Three theoretical frameworks explain this phenomenon. Self-presentation theory suggests people express consistent attitudes to manage impressions, while cognitive dissonance theory proposes that inconsistency between beliefs and actions creates psychological tension motivating attitude change, particularly when external justifications are weak. Self-perception theory offers an alternative explanation: when attitudes are not firmly established, individuals infer their own attitudes by observing their behavior and its context. The chapter synthesizes these perspectives by noting that cognitive dissonance best explains attitude change following behavior that contradicts existing beliefs, whereas self-perception theory better accounts for attitude formation when individuals lack clear prior attitudes. Overall, the chapter demonstrates that action constitutes a powerful vehicle for self-transformation, suggesting that behavioral change often precedes and facilitates genuine psychological change.
