Subjectivity refers to how someones judgment is shaped by personal opinions and feelings instead of outside influences. It is a form of bias and individuality, and it is partially responsible for why ones perceptions are unique. Subjectivity is the opposite of objectivity, which is based purely on facts and isnt personal. In decision-making, there is always an element of subjectivity involved. Accountants, for example, dislike the subjectivity involved in long-term forecasting. Subjectivity is often mentioned in the philosophy of mind because so much of mentality is subjective, with a special brand of subjectivity present in the case of conscious experience).
