In what way can dissonance be an effective means for changing attitudes and behaviour?

Understanding Cognitive Dissonance

At its core, cognitive dissonance arises from an inconsistency between two or more cognitions (thoughts, beliefs, attitudes). This inconsistency creates a state of psychological tension, which individuals are motivated to alleviate. The magnitude of dissonance depends on the importance of the cognitions, the degree of discrepancy, and the individual’s ability to rationalize the inconsistency.

Mechanisms for Dissonance Reduction

Individuals employ several strategies to reduce cognitive dissonance:

• Changing Attitudes: This involves altering one’s beliefs to align with the behavior. For example, a smoker who knows smoking is harmful might downplay the health risks.
• Changing Behavior: This is the most direct approach, involving altering the behavior to align with the attitude. The smoker could quit smoking.
• Adding Consonant Cognitions: This involves justifying the inconsistency by adding new beliefs that support the behavior. The smoker might believe smoking helps them relax and manage stress.
• Reducing the Importance of the Conflict: Minimizing the significance of the conflicting cognitions. The smoker might believe that life is short and enjoying it is more important than longevity.

Dissonance as a Tool for Attitude and Behavior Change

The effectiveness of dissonance as a change mechanism stems from its internal motivation. Unlike external persuasion, dissonance creates a self-persuasion effect, leading to more lasting changes. Several techniques leverage this principle:

1. Insufficient Justification

When individuals perform a counter-attitudinal behavior with minimal external justification, they experience greater dissonance and are more likely to change their attitude to align with the behavior. Festinger and Carlsmith’s (1959) classic study demonstrated this: participants paid $1 to lie about a boring task rated it as more enjoyable than those paid $20, as the $1 group had insufficient justification for their lie and thus altered their attitude.

2. Effort Justification

People tend to value outcomes they have put significant effort into achieving, even if those outcomes are not inherently rewarding. This is because experiencing dissonance between the effort expended and the disappointing outcome motivates attitude change to justify the effort. For example, individuals who undergo a severe initiation to join a group tend to rate the group more positively.

3. Post-Decision Dissonance

After making a difficult decision, individuals often experience dissonance because they focus on the positive aspects of the chosen option and the negative aspects of the rejected option. To reduce this dissonance, they enhance their evaluation of the chosen option and devalue the rejected one.

Real-World Applications

Dissonance principles are applied in various fields:

• Marketing: Creating situations where consumers justify their purchases, increasing brand loyalty.
• Health Promotion: Encouraging small behavioral commitments (e.g., signing a pledge) to create dissonance if individuals don’t follow through, prompting healthier choices.
• Political Campaigns: Highlighting inconsistencies in opponents’ statements or actions to create dissonance among voters.

However, it’s important to note that dissonance effects are moderated by factors like self-esteem and cultural norms. Individuals with high self-esteem may be less susceptible to dissonance, while collectivist cultures may prioritize group harmony over individual consistency.
