Which attentional bias makes individuals more likely to notice information confirming their pre-existing beliefs?

Confirmation bias is the attentional bias that makes individuals more likely to notice information confirming their pre-existing beliefs. Confirmation bias is the tendency to selectively attend to, interpret, and remember information that supports existing beliefs or values, while disregarding or downplaying information that contradicts them. This bias affects how people search for, process, and recall information. For example, someone who believes that a particular political policy is effective will be more likely to notice news articles or studies that support that policy, while ignoring or dismissing evidence that suggests otherwise. In the context of the attention economy, algorithms can exacerbate confirmation bias by showing users content that aligns with their past preferences and beliefs, creating an echo chamber where they are primarily exposed to information that reinforces their existing viewpoints. This selective exposure can lead to increased polarization and resistance to alternative perspectives.
