Final answer:
Confirmation bias is the tendency to seek information agreeing with one's views and to avoid opposing information, often leading to a polarized society.
Step-by-step explanation:
The tendency to seek information and media that agree with one's views and to avoid dissonant information is called confirmation bias. This tendency includes behaviors such as searching for, interpreting, favoring, and recalling information in a way that confirms one’s preexisting beliefs and opinions. For example, a person may only read news headlines that support their political views, avoiding exposure to contrary viewpoints. This selective exposure can lead to a more polarized society where differing viewpoints are not considered or respected.
