Stereotypes are a set of beliefs a person holds about the personal attributes of a group of people. The beliefs are commonly held and understood, which allows people to use them as automatic shortcuts when making evaluations and decisions. Because the beliefs are so broadly understood and easily accessible, they can subconsciously influence opinion formation. In the realm of politics, citizens may use stereotypes to guide evaluations of candidates from stereotyped groups (such as African Americans or women) or as they formulate opinions about a policy that may have a particular group as its perceived beneficiary.

Because many commonly held stereotypes—such as that African Americans are lazy or violent—are not socially desirable, they pose a challenge to researchers attempting to measure them effectively. Thus, as social scientists examine the effects of stereotypes on citizen decision-making, it is important that they carefully consider how to best measure stereotypes. The goal should be to create reliable (consistent) and valid (accurate) measures that minimize social desirability in responses. Measures should reflect clear understanding of the content of the stereotype under examination and incorporate a full range of content to reflect it. One part of understanding the content of a stereotype is considering whether the group under examination is a subtype or subgroup of a larger stereotype category. For example, female politicians as a group constitute a subtype of the larger stereotyped group, women, where female politicians share little overlap in terms of stereotype content with women. Similarly, Black politicians are a subtype of Blacks, sharing little stereotype content. Male politicians, in contrast, form a subgroup of men, where they share many characteristics with the larger group, men. Stereotype content has implications for the link between stereotypes and evaluations of political actors or public policies. The ability to accurately measure stereotypes is a necessary step in understanding when and how people use stereotypes to navigate the political arena.

The intersection of two stereotypes is another important consideration, particularly since the combination of two stereotypes may be more than the sum of its parts. When researchers consider the content of stereotypes, the relationship between one stereotype to others (e.g., subtypes or subgroups), and the intersection of stereotypes, they can create improved measures of stereotypes that optimize reliability and validity.

A variety of explicit and implicit measures exist for researchers to consider, including explicit measures, such as semantic differential scales and open- and closed-ended identification of stereotype content, and implicit measures, such as the Implicit Association Test (IAT) and affective attitude measures. Two-step measures can be used to examine stereotype activation and application. While each of these measures has strengths and weaknesses, all are designed to help researchers better measure stereotypes en route to understanding how stereotypes influence peoples’ attitudes and behaviors. Reliable and valid measures of stereotypes—both implicit and explicit—can help us create more accurate understandings of the political world.
