The process of making judgments and formulating convictions is a vital function performed by all human beings. Successful accomplishment of such tasks usually involves the integration of interoceptive cues (i.e. past experience, feeling states, etc.) with exteroceptive, or objective, information. Often, personal idiosyncracies determine the relative amount of flexibility with which convictions or opinions are held, regardless of contradictory information.
