Is there a reason why some women like a guy with chest hair and other women don’t?
has commonly been considered that women’s preference with regard to male body hair changes over the years according to fashion and is influenced by the media. Experimental evidence, however, is currently lacking. We examined the effect of male torso hairiness on Finnish women’s attractiveness ratings by presenting pictures of male torsos before and after the removal of body hair. We found that the women’s preferences correlated strongly with the hairiness of their current partners, suggesting that body hair may…

Is a cheeseburger an effective persuasion tool?
e purpose of this experiment was to follow up on previous findings of a gain in opinion change produced by eating-while-reading (Razran, 1940; Janis, Kaye, and Kirschner, 1965) by testing predictions from a “conditioning” theory and from an alternative explanation in terms of greater receptivity to any communication endorsed by E, the donor of the food. A factorial design was used to determine the extent to which the opinion changes induced by two persuasive communications were influenced by (1) E's giving…

How much of who you choose to date is determined by your preferences?
rriage data show a strong degree of positive assortative mating along a variety of attributes. But since marriage is an equilibrium outcome, it is unclear whether positive sorting is the result of preferences rather than opportunities. We assess the relative importance of preferences and opportunities in dating behaviour, using unique data from a large commercial speed dating agency. While the speed dating design gives us a direct observation of individual preferences, the random allocation of participants across events generates an…

How many of your Facebook friends actually influence your behavior?
e success of Internet social networking sites depends on the number and activity levels of their user members. Although users typically have numerous connections to other site members (i.e., “friends”), only a fraction of those so-called friends may actually influence a member's site usage. Because the influence of potentially hundreds of friends needs to be evaluated for each user, inferring precisely who is influential—and, therefore, of managerial interest for advertising targeting and retention efforts—is difficult. The authors develop an approach…

An easy way for women to be more attractive to men and men to be more attractive to women:
rls, wear red: In many non-human primate species, a display of red by a female increases attraction behavior in male conspecifics. In two experiments, we investigate an analogous effect in humans, specifically, whether red on a woman's shirt increases attraction behavior in men. In Experiment 1, men who viewed an ostensible conversation partner in a red versus a green shirt chose to ask her more intimate questions. In Experiment 2, men who viewed an ostensible interaction partner in a red…
