Perceptual Bias
Perceptual bias is the mind’s habit of seeing things in a tilted way instead of seeing them completely accurately. It means perception is pulled by expectations, past experiences, or feelings, so what is noticed and how it is interpreted is not perfectly objective.
Perceptual bias is when the brain “leans” in a certain direction while looking at people or situations, often without awareness. For example, if someone expects a person to be unfriendly, they may notice only the cold moments and overlook kind ones, so their picture of that person is skewed.
This bias saves mental effort by using shortcuts, but it can also lead to unfair judgements, stereotypes, or misunderstandings. Noticing that perception can be biased is the first step to checking those automatic impressions and asking, “Am I really seeing the full picture here?”
