What is confirmation bias?

The tendency to favor information that confirms existing beliefs or expectations

Confirmation bias is a cognitive bias that leads people to give more weight to information that supports their existing views, while ignoring or downplaying information that contradicts them

Imagine you're a fan of a particular sports team and you only read news articles that praise your team, while ignoring articles that criticize them - this is similar to how confirmation bias works, where you're selectively seeking out information that confirms your existing beliefs

For example, a person who believes that a certain political party is the best may only follow news sources that support that party, and ignore or dismiss news sources that criticize it, demonstrating confirmation bias in action

Confirmation bias can be used to explain why people often resist changing their opinions, even when presented with contradictory evidence, and why they may seek out information that supports their views, such as following news sources or social media accounts that align with their beliefs

One common misconception about confirmation bias is that it's a deliberate attempt to manipulate information, when in fact it's often an unconscious bias that affects people's perceptions and decisions

The concept of confirmation bias was first introduced by psychologist Peter Wason in 1960, and has since been widely studied in the fields of psychology, sociology, and philosophy
