Presidential Elections and Visual Persuasion

With the election season is in full swing, I’m reminded of this interesting experiment run by Bailenson, et al, at Stanford just before the 2004 presidential election:
One week before the 2004 presidential election, participants completed a survey of their attitudes concerning George Bush and John Kerry while viewing photographs of both candidates side by side (See Figure 1). For a random one-third of the subjects, their own faces were morphed with Kerry while unfamiliar faces were morphed with Bush. For a different one-third, their own faces were morphed with Bush while unfamiliar faces were morphed with Kerry. The remaining one-third of the sample viewed un-morphed pictures of the candidates.
Post-experiment interviews demonstrated that not a single person detected that his or her image had been morphed into the photograph of the candidate. Participants were more likely to vote for the candidate morphed with their own face than the candidate morphed with an unfamiliar face. The effects of facial identity capture on candidate support were concentrated among weak partisans and independents; for ‘card carrying’ members of the Democratic and Republican parties, the manipulation made little difference.

We have more affinity for people we perceive to be more like us and subtle changes to a person’s picture have the power to make us like someone more or less. So be a critical consumer of not just the words but also the images of the candidates! Resist the temptation to vote based on gut feelings about affinity and similarity, because these factors can be easily manipulated.
