Female politicians' success can be predicted by their facial features, especially in conservative states where women with more feminine faces tend to do better at the ballot box, a Dartmouth College-led study finds.
The results don't mean a supermodel will win the White House, but they do suggest women's electoral success requires a delicate balance between voters' perception of traditional femininity and political competence. The study appears in the journal Social Psychological and Personality Science. A PDF of the study is available on request. Here is a video animation of the experiment. The study included researchers from UCLA and the University of Delaware.
The researchers used software called MouseTracker that was developed by the study's senior author Jon Freeman, an assistant professor and director of the Social Cognitive & Neural Sciences Lab at Dartmouth. MouseTracker measures computer mouse movements during psychological experiments, revealing how participants' real-time hand movements may be partially pulled toward various alternatives and how their psychological response evolves over time. More than 1,000 scientists around the world are using the software for many purposes, such as detecting cognitive impairments and subtle racial biases, assessing marketing decisions and financial behavior and predicting health outcomes and social inequities.
Previous research has shown that faces with subtle atypical gender cues – women with masculine features and men with feminine features – cause initial uncertainty when people try to categorize them as male or female. Earlier studies also have linked perceptions of competence in male politicians' faces to political success. But the Dartmouth-led study demonstrates for the first time that gendered cues uniquely predict female politicians' electoral success above and beyond competence, suggesting a discrepancy between traits used to evaluate male and female politicians.
"Individuals are highly sensitive to gendered facial cues, and these cues are processed within only milliseconds after seeing another's face," Freeman says. "It's important to examine how facial cues could inadvertently affect female politicians' electoral success, especially given the possibility of a female U.S. president in the near future and the rising number of women in Congress."
The Dartmouth researchers wondered whether the initial confusion over how people perceive the biological and social gendered cues in politicians' faces – such as shape of eyes, cheekbones, jawlines and brows, length of hair, makeup – may influence conservative and liberal voting behavior and election outcomes.
The researchers tracked the computer mouse movements of nearly 300 participants who were shown politicians' faces – the winners and runners-up in U.S. Senate and gubernatorial elections between 1998 and 2010 -- and asked to categorize them as male or female. About 10 percent of the participants were Dartmouth students who viewed the politicians' faces in a controlled lab setting and were asked whether they would vote for them, although no information was provided about the politicians' background, competence or other factors. The other 90 percent of participants lived across the United States and took the facial test over the Internet, providing a diverse national sample.
The results showed that the more participants were drawn to select the male response when categorizing the gender of a female politician's face, the less likely she was to win her election. The lab participants also indicated they would be less likely to vote for such politicians. In other words, female politicians with more feminine features tend to win elections, while those with more masculine features tend to lose. The mouse-tracking technique further revealed that whether a female politician was going to win or lose an election could be predicted within just 380 milliseconds after participants were exposed to her face.
"We show that subtle uncertainty during the initial processing of a face's gender predicts the electoral success or failure of female politicians, and this is a unique effect not explained by perceived competence or attractiveness," says Freeman. "A female politician's success was related to how feminine or masculine her face was perceived less than one half-second after its initial exposure, suggesting that the way a face's gender is rapidly processed may translate into real-world political outcomes."
Importantly, the effects became more pronounced as the conservatism of the constituency increased, which supports previous research indicating that conservatives may be less tolerant of uncertainty. "This is thought to reflect a relatively rigid cognitive style and an emphasis on traditional gender roles," says lead author Eric Hehman, a postdoctoral researcher in Freeman's lab. "In contrast, previous research suggests liberals tend to exhibit greater tolerance of ambiguity and cognitive flexibility."
To quantify each state's conservative to liberal distribution, researchers looked at the margins of victory in each state from the five presidential elections between 1992 and 2008. Differences between conservatives and liberals' tolerance for uncertainty and traditional gender roles may create a volatile situation for female politicians.
"Because masculinity is stereotypically associated with leadership in the U.S., conservatives' preference for traditional gender roles and low tolerance for uncertainty may require women's leadership aspirations to be tempered by strong associations with femininity, particularly in their appearance," Hehman says.
