Which concept describes the tendency to attribute one's own feelings and characteristics to others?

The concept that describes the tendency to attribute one's own feelings and characteristics to others is known as projection. This psychological phenomenon occurs when individuals project their own thoughts, feelings, and attributes onto others, often without being consciously aware of it. For example, if someone is feeling insecure, they might assume that others perceive them as insecure too, even if that is not the case. Projection can influence interpersonal interactions, as individuals may misinterpret the behavior of others based on their own internal state rather than the reality of the situation.

The other concepts presented do not capture this specific cognitive bias. The primacy effect refers to the tendency to remember the first items in a list better than those presented later. Stereotyping involves generalized beliefs or assumptions about a group of people, which is distinct from the personal attribution inherent in projection. Closure, although relevant to completing or filling in missing information, does not specifically relate to projecting one's own characteristics onto others. Thus, projection accurately encapsulates the tendency described in the question.
