Looks like a winner

MIT political scientists have measured the effect that candidates' looks have on their electoral prospects.

MIT political scientists demonstrate how much candidate appearances affect election outcomes, globally.

When you vote in an election, your choice is surely not influenced by anything as superficial as a candidate’s looks, right?


New research from MIT political scientists shows that the appearances of politicians do indeed strongly influence voters — and that people around the world have similar ideas about what a good politician looks like. While few political observers would be surprised to learn that good looks earn votes, the MIT researchers have quantified a phenomenon that is more often assumed to be true than rigorously measured.

“Ever since Aristotle, people have written about the concern that charismatic leaders who speak well and look good can sway votes even if they do not share the people’s views,” acknowledges Gabriel Lenz, an associate professor in the Department of Political Science at MIT, and a co-author of the study.

To test this idea, though, Lenz and his colleagues showed voters in the United States and India pairs of candidate photos from real election matchups in Brazil and Mexico. When asked which candidate would make a better elected official, the participants in the study, regardless of where they lived, largely selected the same candidates. Moreover, their choices corresponded closely to the outcomes of those Brazilian and Mexican races, meaning the public attribution of good looks to a candidate is a leading indicator of a campaign’s result.

“We were a little shocked that people in the United States and India so easily predicted the outcomes of elections in Mexico and Brazil based only on brief exposure to the candidates’ faces,” says Lenz. “These are all different cultures, with different political traditions and different histories.”

In the study, the researchers showed voters pairs of candidates from 122 elections in Mexico and Brazil. The participants in the study were asked which candidate would be a better elected official. Respondents in India and the United States agreed with each other about 75 percent of the time when asked which candidate seemed superior; a group of respondents in the United States and Mexico agreed with each other about 80 percent of the time.

In turn, simply knowing which candidate the participants judged to have a superior appearance allowed the researchers to correctly predict the winner in 68 percent of Mexican elections and 75 percent of some Brazilian elections. “These are very large effects,” the authors note in the working paper, “Looking like a Winner: Candidate Appearance and Electoral Success in New Democracies,” which will be published in the journal World Politics this fall.

Of all the politicians in the study, only six candidates in Mexico and 16 candidates in Brazil were female. (The researchers chose pairings on the basis of photo availability; the pairings do not necessarily represent the precise proportion of female candidates in all such races.) Other researchers in the field, as the paper notes, have found that female candidates fare better in surveys of looks than they do in actual elections. This disparity between survey outcomes and ballot box results, Lenz thinks, could indicate that male participants in these surveys do not want to appear prejudiced in public-opinion studies, but vote in ways that differ from their survey responses. “We would like to study these issues more,” Lenz adds.

Lenz conducted the study along with Chappell Lawson, also an associate professor of political science at MIT, Michael Myers, a research affiliate with MIT’s Department of Political Science, and Andy Baker, a political scientist at the University of Colorado.

The paper is an “interesting and innovative study,” writes Panu Poutvaara, an economist at the University of Helsinki who also studies the influences of candidate appearances, responding to questions by e-mail. In Poutvaara’s view, by helping to confirm the general connection between good looks and ballot-box success, the study paves the way for future research that should address precisely why voters favor good-looking candidates: “Is it because voters either enjoy watching good-looking politicians on TV, or think that they are better in social interactions?”

Lenz and his colleagues are addressing this question from a slightly different angle in additional, ongoing research. In a forthcoming study, they find that “low-information voters” are especially likely to choose candidates based on looks. “These are people who don’t know much about politics, but watch a lot of TV,” says Lenz. The researchers are currently writing a paper based on this latter project.

In the animal world, the strongest male gets the chance to mate. Because the animal wants to entail good genes on next generation. Perhaps the strongest male has a good appearance at the same time. Maybe it's our nature to choose a good looking person to be the winner.

There is no fate. But when the egg and the sperm merged, many thing of us was destined. I wish that MIT's Department of Biomedicine can change our genes as we wanted in the near future.

it looks like a good appearence is very important for man

I have always believed this to be the case. Indeed, most charismatic leaders exhibit general looks or behaviour different from the rest of the crowd. But then again I wonder - isn't perception of good looks subjective? How can some one from India, US and Latin America pick the same individual? Would that also imply that irrespective of race or ethnicity, our perception of beauty / looks is the same ?

I concur with the fact that the approach and appearance of the candidate does, in fact, affect the amount of votes the candidate may receive. It's only natural that people would read and or possibly stereotype a person by his appearance. But as an additional note, you can actually tell a person's attitude from how they carry themselves. So I do in fact, agree with the concluded research that appearance does affect popularity. In it's own right. :P

Editor's Note: The article and accompanying photo have been modified to address the ways gender issues were taken into account in this study.

Dear Allen and other readers, you should look at the work of Robert Sapolsky who shows that while the so-called alpha males are off fighting, the female often chooses the male who is in the bushes with her demonstrating his willingness to build a family. So don't believe everything you think you've been taught! Another good book on this topic is Blink! by Malcolm Gladwell.

I would have liked the researchers and Peter Dizikes to have commented on the fact that this study involves only males. Judging by the photo, these were only white and Latino men. Where are the women?!

How is this study substantially different from Alex Todorov's work, published in Science in 2005?

It would be interesting to rerun the experiment for elections that have not yet taken place to see the extent to which this can be used to determine future outcomes. That study might take longer, but perhaps they're already looking at it.

I don't think it has to do with animal tendencies. There is such a thing as physiognomy. The level of perception in this regard is relative to the observer's degree of intuition.
