Manipulative? Maybe. But effective? A new study suggests yes, perhaps to a greater extent than any lush landscape. In Psychological Science, a group of marketing professors from the Canda and South Korea suggest that we're more likely to support a social cause if the campaign features some kind of face. Any kind of face, really. The study mainly looked at environmental campaigns, featuring different inanimate objects with faces that asked people for help. Participants were more likely to support campaigns that used human-like, anthropomorphized objects, which the researchers suggest could be the result of "anticipatory guilt," the feeling that not acting will make someone feel guilty in the future. So to avoid that guilt, people donate, the hypothesis goes.
