Confirmation Bias

What Is Confirmation Bias

Confirmation bias is the cognitive tendency to preferentially seek, remember, and interpret information that supports what one already believes, while ignoring or dismissing information that contradicts those beliefs. If you think "that person can't be trusted," their honest actions go unnoticed, but the slightest suspicious behavior reinforces your conviction with a "knew it." This is the classic operation of confirmation bias.

The Three Stages of Confirmation Bias

Confirmation bias operates at all three stages of information processing. First, the "information gathering" stage. You choose news sources that support your views and avoid media with opposing perspectives. Second, the "information interpretation" stage. You interpret ambiguous information in a way that favors your position. This is why both proponents and opponents can cite the same statistical data as evidence for their respective arguments. Third, the "information recall" stage. Information consistent with your beliefs is remembered vividly, while contradictory information is easily forgotten. Through this triple filter, people unconsciously construct an information environment that continuously reinforces their beliefs.

Why Confirmation Bias Is So Powerful

What makes confirmation bias so insidious is that it operates regardless of intelligence or education level. In fact, people with higher intellectual ability also have a greater capacity to construct sophisticated arguments supporting their beliefs, meaning confirmation bias can manifest in more refined forms. The first step in coping is to accept as a given that you are under the influence of confirmation bias. The self-perception that "I am objective" is the most formidable shield confirmation bias has. Deliberately seeking opposing viewpoints and striving to understand the strongest counterarguments to your own beliefs is one of the few ways to mitigate this bias.
