Assumed similarity bias

The Assumed Similarity Bias is a cognitive bias where individuals overestimate the similarity of their own beliefs, characteristics, and behaviors to those of others. This bias can lead people to believe that others think and act like them more than they actually do.

For example, someone who enjoys hiking might assume that most people also enjoy hiking, even though in reality, hiking might not be as popular or enjoyable for others. This bias can affect how people perceive and interact with others, leading to misunderstandings or miscommunications.

Assumed similarity bias can be particularly strong in situations where people are more familiar or close to each other, such as within a family, a close-knit community, or among friends. It can also influence how people make decisions, as they may assume that others would make the same choices as they would.

Being aware of this bias can help individuals recognize when they might be overestimating the similarity between themselves and others, leading to more accurate perceptions and better communication.
