Presidential Primaries Votes Were Correctly Predicted in August 2007
- by New Zealand School Girls
Snap judgments of New Zealand high school girls helped researchers at the University of Pennsylvania to predict that
John McCain would be the Republican nominee for the US presidency later this year. McCain came from nowhere to defeat
once favoured Republicans Rudy Giuliani and Fred Thompson. This was no surprise to a team of researchers based at the
Wharton Business School. They predicted this outcome in August 2007 by relying on the snap judgments of New Zealand
schoolgirls.
Professor Scott Armstrong of the Wharton School and his colleagues Professors Randall Jones in the US, Malcolm Wright in
Australia, and Dr Kesten Green in New Zealand had their interest piqued by the work of Princeton Professor Alexander
Todorov. Todorov found that snap judgments of competence, based on a quick look at pictures of candidates’ faces, had
done a good job of predicting the winners of congressional and senate races. The Wharton team extended this research to
US presidential primaries.
From May through mid-August 2007 the researchers obtained ratings of facial competence of 24 potential contenders for
the major party nominations for president in 2008. The researchers provided no other information to the raters than
color portrait photographs of the candidates. Because the team wanted ratings made in the absence of any other knowledge
about the candidates, they relied heavily on university students in Australia and New Zealand and high school girls in
New Zealand, who were unlikely to be familiar with the candidates. Even so, some of the students recognized Clinton and
Obama, in particular, and those ratings were excluded. In the end, the researchers obtained between 139 and 348 ratings
for each contender.
In its 2 November 2007 issue, Science published a report on this study when polls had McCain at 15%, still trailing
Giuliani and Thompson for the Republican nomination, and support for Democrat Obama was in the low 20s. The researchers
hypothesized that the candidates' standing in the polls would move closer to their facial competence rankings as more
voters became familiar with their appearance. And so it happened.
Warning: while it may be efficient for people to choose a president on the basis of snap judgments, to do so may not
provide the best leadership. There is no relationship between looking competent and the real thing. The researchers
suggest that political parties should increase their chances by putting forward competent-looking candidates, but that
voters should make decisions after becoming familiar with the candidates’ policies.
