What is Confirmation Bias?
Confirmation bias is a cognitive bias that involves favoring the information confirming one’s previously existing biases or beliefs. Hence, the investor would only seek information that will guarantee their existing belief and filter out information based on that. In its true essence, the confirmation bias theory states that investors would see only what their belief system allows them to see.
For an investor or a business executive, it is important to strike the right balance between their belief system and the actual availability of data. The database gives a detailed idea of the reality of the concept and its implications. Moreover, the hierarchy in a business organization is framed to eliminate individuals’ biases at different levels.
- Confirmation bias is a cognitive bias where individuals tend to favor and seek out information that confirms their existing beliefs while disregarding or downplaying contradictory evidence.
- It can significantly impact investors as it influences their perceptions and judgments about financial markets, leading to a biased interpretation of information.
- It can sometimes reinforce investors’ confidence in their beliefs and contribute to successful outcomes based on their past experiences.

Confirmation Bias Explained
Confirmation bias is the phenomenon where an individual interprets, processes, and makes decisions based on their pre conceived notions or commonly referred to as their belief systems. These decisions or the act of looking at things based on principles are unintentional more often than not.
As a result, individuals or organizations ignore or look beyond information that is against their belief systems. These can sometimes result in good outcomes or sometimes otherwise. It is vital to rely on an actual database as well to reconfirm or affirm the interpretation of the situation.
In an extremely dynamic and diverse environment such as investing or business, it is important to remain objective about the happenings in the market to stay on top of trends and make the most of them in monetary terms.
It is one of the most common biases seen in the real world and day-to-day life, where people seek only evidence that supports their initial view and filters any information that would disconfirm their belief. To avoid confirmation bias psychology, one should look for contrary advice, avoid confirming questions, seek more information, study the impact of the same, and then act accordingly.
Video Explanation of Confirmation Bias
Let us understand the different types of confirmation bias psychology present in the market through the discussion below. These types breed from different levels of understanding and the strength of the belief system of the individual.
- Search For Information: When an individual searches for details and depth about a concept, company, or asset class, they tend to look for and search for information that aligns with their belief system and their past experiences that have been hardwired into their system. As a result, more vital information or the current trend in the market might get missed.
- Interpretation of Information: Even if the individual goes out of their way to search and analyze the information about the concept or business, their interpretation of the information might be based on their principles and anything from the other end of the spectrum might be conveniently ignored.
- Experience: This is also referred to as a memory recall of the information. For example, if the stock markets have shown a decline in the past week, and gold prices have shown improvement in the past in similar circumstances, the investor or the business executive might think the same will happen this time around too without digging out more information or data to support such a belief.
Let us understand the intricate details of the confirmation bias theory with the help of a few examples.

How To Avoid?
To ensure no profitable information bites the dust due to ignorance or due to pre-determined notions, it is important to understand how confirmation bias psychology works and how it can be avoided. Let us understand this pivotal aspect of the concept through the discussion below.
The first step to eliminating such biases is to understand personal belief systems and how these systems affect objectivity in interpretation and decision-making. Without this step, it becomes difficult to sort such situations because only when the root of a problem is detected, it can be completely eliminated.
- Critical Evaluation:
Every piece of information in the business world can be turned into a profitable deal or a deal that went down the drain due to multiple reasons. Therefore, it is vital to critically analyze and scrutinize every piece of information as objectively and practically as possible.
