People have a tendency to judge a person not in isolation but in comparison to others. In some instances, this highlights the contrast between people and our judgements are formed not by the qualities that each person possesses but by their differences from each other. In particular, this contrast effect can arise in employee selection and occurs when selectors compare candidates against one another rather than with the person specification for the vacancy that is to be filled.
