How Cognitive Dissonance Influences Our Beliefs and Actions


Cognitive dissonance, a term coined by psychologist Leon Festinger in the 1950s, refers to the discomfort experienced when holding two contradictory beliefs or when our actions contradict our beliefs. This psychological concept plays a significant role in how we shape our beliefs, justify our actions, and navigate the complexities of decision-making.

The Mechanics of Cognitive Dissonance

  • Contradictory Beliefs and Behaviours: Cognitive dissonance arises when we face a conflict between what we believe and what we do. For instance, a person who values health but smokes cigarettes might experience cognitive dissonance.
  • Dissonance Reduction: To alleviate the discomfort of dissonance, we often unconsciously adjust our beliefs or justify our actions. In our example, the smoker might downplay the health risks of smoking or rationalise it by believing it relieves stress.

Cognitive Dissonance in Decision-Making

Cognitive dissonance can significantly influence our decision-making processes. After making a choice, particularly a difficult one, we often experience dissonance. To justify our decision, we might overemphasise the chosen option's positives and the rejected option's negatives.

Cognitive Dissonance in Belief Systems

Our core beliefs and values are not immune to the effects of cognitive dissonance. When confronted with evidence that challenges our beliefs, we might experience dissonance. We may either adjust our beliefs or dismiss the conflicting evidence to resolve this.

Cognitive Dissonance in Social and Political Contexts

Cognitive dissonance can lead to entrenched opinions and resistance to changing viewpoints in social and political spheres. For instance, when people are presented with facts contradicting their political beliefs, they might rationalise or reject the information to maintain consistency with their beliefs.

Psychological Strategies to Handle Cognitive Dissonance

  • Awareness and Acknowledgment: The first step in dealing with cognitive dissonance is recognising when it occurs. Awareness of the discomfort can help us better understand our reactions and choices.
  • Openness to Change: Cultivating an openness to change and challenging our beliefs can lead to personal growth and a more nuanced understanding of the world.
  • Seeking Consistency: Striving for consistency between our actions and beliefs can lead to more harmonious and authentic living. This might involve changing behaviours that contradict our values or re-evaluating beliefs that no longer serve us.
  • Critical Thinking: Engaging in critical thinking and seeking evidence before forming or altering beliefs can reduce the likelihood of experiencing dissonance.


Cognitive dissonance is a powerful psychological phenomenon influencing our beliefs, decisions, and actions. By understanding how it works and learning to manage it, we can make more informed decisions, hold beliefs that align with our actions, and navigate the complexities of conflicting information with greater clarity and openness.


All the best!
