What is Cognitive Dissonance?
Cognitive dissonance is the mental discomfort experienced by a person who holds two or more contradictory beliefs, ideas, or values, or when their beliefs are inconsistent with their actions. This psychological stress arises from the mind's inherent need for consistency.
Section 2: Key Principles
The core principle is that individuals are motivated to reduce this internal inconsistency. To relieve the tension of dissonance, a person may change one of their conflicting beliefs, change their behavior to align with their beliefs, or add a new belief to rationalize the conflict and restore balance.
Section 3: A Practical Example
Consider a person who smokes cigarettes (behavior) but also believes that smoking is unhealthy (belief). The conflict between their action and belief creates cognitive dissonance. To reduce this discomfort, they might quit smoking (change behavior), convince themselves the health risks are exaggerated (change belief), or justify their action by saying it helps them manage stress (add a new belief).
Section 4: Importance and Applications
Understanding cognitive dissonance is crucial for explaining many aspects of human behavior, including decision-making, persuasion, and self-justification. The concept is widely applied in fields like marketing, therapy, and public health campaigns to understand and influence attitude and behavior change.
