theory explains why we feel uncomfortable when our thoughts and actions don't match up. It's a key concept in understanding how attitudes change and why we sometimes adjust our beliefs to fit our behavior.
This theory connects to the broader topic of by showing how internal conflicts can lead to shifts in our views. It's not just about outside influences – our own actions can reshape our attitudes too.

Cognitive dissonance theory explains psychological discomfort arising from conflicting thoughts or behaviors
Developed by in 1957, describes mental tension when beliefs and actions misalign
Occurs when individuals hold contradictory beliefs or engage in behavior inconsistent with their attitudes
Motivates people to reduce discomfort by changing beliefs, attitudes, or behaviors
Intensity of dissonance depends on importance of conflicting elements and number of dissonant thoughts
Strategies for Reducing Dissonance
strategies aim to alleviate psychological discomfort
Changing one of the dissonant elements (attitudes, beliefs, or behaviors)
Adding new consonant elements to outweigh dissonant ones
Reducing importance of dissonant elements
Seeking information supporting the chosen alternative
Avoiding information contradicting the chosen alternative
Counterattitudinal Behavior and Attitude Change
involves acting contrary to one's beliefs or attitudes
Often leads to attitude change to align with behavior, reducing dissonance
demonstrates this effect in experimental settings
Attitude change more likely when external justification for behavior is minimal
Internal justification process leads to attitude shift to match behavior
Attitude Polarization and Group Dynamics
occurs when exposure to conflicting information strengthens pre-existing attitudes
amplifies this effect in social settings
contributes to polarization by seeking confirming information
reinforces existing beliefs, leading to stronger attitudes
Can result in increased group cohesion but also exacerbate social divisions
Experimental Paradigms
Forced Compliance Paradigm
Forced compliance paradigm investigates attitude change following counterattitudinal behavior
Participants induced to engage in behavior contrary to their beliefs or attitudes
Classic study: Festinger and Carlsmith (1959) boring task experiment
Participants paid 1or20 to tell others the task was enjoyable
$1 group experienced more dissonance, leading to greater attitude change
Demonstrates inverse relationship between external justification and attitude change
Free Choice Paradigm
examines decision-making and
Participants choose between similarly attractive alternatives
After choice, tendency to enhance chosen option and devalue rejected option
observed as cognitive dissonance reduction strategy
Jack Brehm's classic study (1956) with household appliances demonstrates this effect
Choice-induced preference change persists over time, influencing future decisions
Induced Compliance and Attitude Change
involves persuading individuals to act against their attitudes
Often used in experimental settings to study cognitive dissonance effects
Minimal external pressure or reward maximizes dissonance and attitude change
uses this principle in real-world persuasion contexts
also leverages induced compliance for behavior change
Effort Justification and Cognitive Dissonance
explains tendency to value outcomes more when effort is expended
Based on cognitive dissonance theory: high effort for low-value outcome creates dissonance
and Mills' (1959) study on group initiation demonstrates this effect
Participants who underwent severe initiation valued group membership more
Applies to various contexts (hazing rituals, difficult academic programs)
Explains sunk cost fallacy in decision-making processes
Alternative Explanations
Self-Perception Theory as an Alternative Framework
proposed by Daryl Bem as alternative to cognitive dissonance theory
Suggests individuals infer their attitudes by observing their own behavior
Assumes people have limited introspective access to their internal states
Explains attitude change without invoking internal psychological tension
Predicts similar outcomes to cognitive dissonance theory in many situations
Differences emerge in situations involving clear pre-existing attitudes
Overjustification effect explained by self-perception theory
Debate continues over which theory better explains various phenomena
Some researchers propose integrative models combining both theories
Highlights importance of considering multiple explanatory frameworks in social psychology
