... In Study 1, perceivers were able to accurately distinguish whether U.S. Senate candidates were either Democrats or Republicans based on photos of their faces. Study 2 showed that these effects extended to Democrat and Republican college students, based on their senior yearbook photos. Study 3 then showed that these judgments were related to differences in perceived traits among the Democrat and Republican faces. Republicans were perceived as more powerful than Democrats. Moreover, as individual targets were perceived to be more powerful, they were more likely to be perceived as Republicans by others. Similarly, as individual targets were perceived to be warmer, they were more likely to be perceived as Democrats ...
Some characteristics are known to be more legible from our faces than others. For instance, visually obvious characteristics such as age, race, and sex are rapidly and readily perceived from facial appearance <3>, <9>–<10>. Yet there is also evidence that aspects of individuals that are considerably less obvious are also perceived somewhat effortlessly. For example, sexual orientation is perceived accurately, rapidly, and automatically from the face and its features <11>–<13>. The rates of accuracy in perceiving sexual orientation are not as high as those for age, race, and sex, however. Rather, characteristics such as sexual orientation and religious group membership tend to be fairly ambiguous to perceivers. Despite the perceptual ambiguity of these categories, perceivers' rates of accuracy in categorizing others along the dimensions of religion and sexual orientation are significantly greater than what would be expected from mere chance guessing <14>–<16>. Thus, even subtle differences in perceptual cues may lead to accurate perceptions.
One particularly consequential judgment is political candidates' actual electoral success based on perceivers' naïve judgments of personality traits from the candidates' faces. Several studies have found that judgments of competence and power from the faces of political candidates in Western cultures are significantly related to the candidates' margin of victory <17>–<19>. Indeed, even children's judgments of politicians' faces can predict their electoral success <20> and judgments of power and warmth from faces can predict electoral outcomes across cultures <19> ...
