Difference Between Cognitive bias and Confirmation bias

What is Cognitive Bias?

Cognitive bias refers to systematic patterns of deviation in thinking, which can lead individuals to make irrational judgments or decisions.


Imagine someone who strongly believes that a specific brand of electronic devices is superior to others. When researching online for reviews about these devices, they only focus on positive testimonials and ignore negative feedback. This person selectively seeks and interprets information that confirms their preexisting belief in the brand’s superiority, disregarding any evidence that might challenge their perspective.


Cognitive biases are generally considered to be systematic patterns of thinking that can lead to errors, distortions, and irrational judgments. However, in some cases, they might offer certain advantages or serve specific purposes:

  • Cognitive Efficiency
  • Decision Speed
  • Social Bonding
  • Confidence Boost
  • Emotional Comfort
  • Simplification
  • Rapid Learning
  • Cultural Adaptation
  • Evolutionary Advantage


However, cognitive biases also have significant disadvantages:

  • Inaccurate judgments
  • Prejudice and discrimination
  • Poor problem-solving
  • Impact on relationships
  • Financial losses

What is Confirmation Bias?

Confirmation bias is a phrase used in cognitive psychology to describe how people prefer information that supports their already-held opinions.


Suppose a person strongly believes that a particular diet plan is the most effective for weight loss. They might actively search for success stories and positive testimonials from people who have followed that diet plan and lose weight. At the same time, they might ignore or dismiss any scientific studies or accounts of individuals who did not achieve the desired weight loss results with that diet plan. This person’s selective attention and interpretation of information are indicative of confirmation bias.


While confirmation bias is generally considered a cognitive limitation, it can have some perceived advantages:

  • Confirmation bias can provide individuals with a sense of validation and reinforcement of their beliefs, which may contribute to their overall confidence and self-esteem.
  • By focusing on information that supports their existing beliefs, people may experience less cognitive dissonance—the discomfort that arises from holding conflicting or inconsistent beliefs.


Confirmation bias can lead to numerous disadvantages and negative consequences:

  • Inaccurate beliefs
  • Closed-mindedness
  • Polarization and echo chambers
  • Impaired decision-making
  • Hindrance to learning

Differences Between Cognitive Bias and Confirmation Bias.

The discomfort caused by possessing two or more contradicting cognitions (e.g., behaviors, values, attitudes, beliefs) is referred to as cognitive dissonance. Confirmation bias, on the other hand, relates to our inclination to seek out and remember information that confirms our ideas, values, and behaviors.

When to Use Cognitive Bias?

Cognitive biases are not something that you consciously use deliberately. Instead, cognitive biases are inherent tendencies in human thinking that affect how we perceive, interpret, and make judgments about the world around us. They are automatic and unconscious processes that influence our thoughts and decisions.

However, it is essential to be aware of cognitive biases and understand how they can impact our thinking and decision-making. By recognizing these biases, we can take steps to mitigate their effects and make more rational and informed choices.

Here are some situations where being aware of cognitive biases can be beneficial:

  1. Decision-making: When making important decisions, being aware of biases like confirmation bias, anchoring bias, or overconfidence bias can help you critically evaluate information and consider different viewpoints.
  2. Problem-solving: Understanding biases such as the availability heuristic and representativeness heuristic can help you avoid jumping to conclusions based on limited information and instead seek more comprehensive evidence.
  3. Negotiation and conflict resolution: Recognizing biases like reactive devaluation and the halo effect can aid in understanding and managing personal biases that may influence negotiations and relationships.
  4. Learning and growth: Acknowledging cognitive biases can foster a growth mindset, encouraging you to be open to new ideas and alternative perspectives for continuous learning and personal development.
  5. Interpersonal relationships: Awareness of cognitive biases can improve empathy and communication by helping you understand how biases might influence your perceptions of others.
  6. Media consumption: Being conscious of biases like the bandwagon effect and filter bubbles can help you critically assess information from different sources and avoid getting trapped in echo chambers.
  7. Designing systems and processes: When designing products, services, or policies, considering cognitive biases can help create user-friendly experiences and avoid unintentionally encouraging biased behavior.

When to Use Confirmation Bias?

There might be certain limited contexts where confirmation bias could have a potentially positive impact:

  • Building Confidence: In situations where you need a boost in confidence or motivation, you might deliberately focus on positive feedback and success stories related to your goals. While this can provide temporary encouragement, it’s important to balance this with a realistic assessment of challenges and potential obstacles.
  • Affirmation of Identity: Some forms of confirmation bias can be used to affirm one’s identity and sense of belonging. For example, seeking out literature or communities that align with your cultural or personal identity can provide a sense of connection and understanding.
  • Maintaining Relationships: In personal relationships, focusing on the positive aspects and qualities of others can foster goodwill and maintain healthy interactions. However, this should not lead to ignoring or downplaying negative aspects that might need addressing.
