This is the tendency to compare candidates to each other, rather than to an objective set of criteria or standards. For example, if we interview two candidates in a row and one is stronger in a particular area, we may be more likely to rate the second candidate lower in that same area, even if they are equally qualified. The contrast effect can cause us to make unfair or inconsistent evaluations of candidates, and it can make us less likely to consider each candidate on their own merits.
