Are You Trapped in Your Own Thoughts? The Impact of Confirmation Bias

Updated: Jun 26, 2023

Confirmation bias is a cognitive bias that occurs when individuals seek out or interpret information in a way that confirms their pre-existing beliefs or hypotheses. This bias can be observed in a variety of contexts, including politics, religion, and personal relationships. In this blog post, we will explore the concept of confirmation bias in more detail, discuss its potential implications, and offer some suggestions for how to overcome it.

The psychology of confirmation bias

Confirmation bias is rooted in the way the human brain processes information. When we encounter new information, our brains work to make sense of it by relating it to our existing beliefs and knowledge. This process can lead to a tendency to seek out information that confirms what we already believe and to overlook or discount information that challenges our beliefs.

There are several reasons why confirmation bias can be so powerful. First, our beliefs are often tied to our sense of identity and self-worth. If someone challenges our beliefs, it can feel like a personal attack. Additionally, we tend to be more attentive to information that is emotionally charged or resonates with us on a personal level. This can cause us to be more likely to remember and prioritize information that confirms our beliefs.

Examples of confirmation bias

Confirmation bias can manifest in a variety of ways, from everyday conversations to more complex decision-making processes. Here are a few examples:

  • Political beliefs: Many people have strong political beliefs and are more likely to seek out news sources and social media posts that align with their views. They may also dismiss information from sources that they perceive as biased or disagreeable.

  • Medical decisions: Patients who are already convinced that a particular treatment or medication is the best option may seek out information that confirms their beliefs and overlook potential risks or side effects.

  • Hiring decisions: Hiring managers may unconsciously favor candidates who have a similar background or share similar beliefs or values.

Implications of confirmation bias

Confirmation bias can have a variety of negative effects on individuals and society as a whole. It can lead to polarized political discourse, contribute to the spread of misinformation, and impede progress in scientific research. It can also lead to poor decision-making in personal and professional contexts, as individuals may overlook important information that contradicts their preconceived notions.

Overcoming confirmation bias

Overcoming confirmation bias can be challenging, but it is possible. Here are a few strategies that may help:

  • Seek out diverse perspectives: Make an effort to seek out information from a variety of sources, even those that challenge your beliefs. This can help you gain a more well-rounded understanding of an issue.

  • Be aware of your emotions: Try to be aware of how your emotions may be influencing your interpretation of information. If you find yourself feeling defensive or resistant to new information, take a step back and try to approach the information more objectively.

  • Consider the evidence: When evaluating new information, make an effort to consider the evidence objectively rather than simply looking for information that confirms your beliefs.

  • Challenge your assumptions: Try to be open to the possibility that your beliefs may be wrong or incomplete. Ask yourself what evidence you would need to change your mind about a particular issue.


Confirmation bias is a pervasive and often subtle cognitive bias that can have negative consequences for individuals and society as a whole. By being aware of this bias and making an effort to seek out diverse perspectives and consider evidence objectively, we can work to overcome it and make more informed decisions.
