COGNITIVE DISSONANCE
Cognitive Dissonance
The Psychology of Internal Consistency and Justification
Cognitive dissonance is the mental discomfort you feel when your beliefs, values, or attitudes clash with your actions or with each other. To ease that discomfort, people often change their beliefs, justify their behavior, or find ways to make things feel consistent.
What Cognitive Dissonance Means
The theory describes the tension that arises when someone holds two conflicting cognitions (beliefs, values, or attitudes) or when their behavior contradicts their beliefs. Humans strive for internal consistency; when inconsistency arises, it creates discomfort, motivating us to resolve it.
Everyday Examples
- Smoking vs. Health Beliefs: A person smokes but knows it causes cancer. The clash between behavior and health values creates dissonance.
- Diet vs. Indulgence: Someone values healthy eating but eats fast food, justifying it by saying, “I deserved a treat today.”
- Work vs. Values: An employee who values honesty lies to protect their job, pushing them to rationalize the act or reconsider their values.
How People Reduce Dissonance
There are several mental strategies humans use to regain equilibrium:
- Change behavior: Quitting the action to align with the belief.
- Change beliefs: Convincing oneself the contradiction isn't "that bad."
- Add new cognition: Finding a new reason to support the behavior (e.g., "smoking reduces my stress").
- Rationalize: Claiming that "many people do it and live long lives."
