Should you trust your gut to tell you who is a good person?
mans behave altruistically in one-shot interactions under total anonymity. In search of explanations for such behavior, it has been argued that at least some individuals have a general tendency to behave altruistically independent of profitability. In fact, a stable altruistic trait would be adaptive if it were recognizable. Then, altruists could choose each other in order to retain benefits through mutual cooperation. Previous research has shown that individuals can predict the degree of altruistic behavior of strangers by reading signs…

Is “tit-for-tat” the best way to deal with people?
recent episode of the consistently excellent Radiolab explored the idea, covering the work of Robert Axelrod. Turns out the age old cliche can be an incredibly powerful way to deal with others: A tit-for-tat strategy plays the iterated prisoners' dilemma game by cooperating on the first move, and then making the same choice as the other player did on the previous move. This strategy has been shown to be a very robust in that it does well with a…

Are people more fair with those who are attractive?
ciprocity evolves only when social partners reliably repay, with interest, the investments of others. However, not all individuals are equally able—or motivated—to recompense others satisfactorily. As such, reciprocity relies greatly on the capacities and motives of partners. Apparent health may provide a cue to the value of potential exchange partners in this regard: healthier individuals will tend to live longer and accrue more, higher quality resources, thus increasing the incentives for mutual cooperation. In a monetary exchange task, we show…

Does humor mentally disarm us?
is article explores humor's impact on cognitive processing of political messages. Although recent research has pointed to effects of late-night comedy viewing on political attitudes and cognitions (Moy, Xenos, & Hess, 2003; Young, 2004, 2006), scant attention has been paid to the development of a theoretical model to account for these outcomes. This manuscript posits that humor suspends argument scrutiny of the premise of a given text through various cognitive mechanisms involving processing ability and motivation. Four different pathways accounting…

Another way to improve your persuasion skills:
ke sure your body language matches your verbal strategy: How can we be more successful in persuading others and increase the odds of behavioral compliance? We argue that when a verbal influence strategy is embedded in a nonverbal style that fits its orientation, this boosts the strategy's effectiveness, whereas a misfit attenuates its impact. In field-experiment 1, agents tried to persuade participants in buying a candybox by using an approach-oriented strategy (Door-In-The-Face, DITF). An eager nonverbal style increased the impact…

Do stores trick you into buying more by stocking less?
elf-based scarcity in the form of relative stocking level depletion significantly affects consumer preferences (van Herpen et al. 2009). While both popularity and quality inferences are induced by stocking-level depletion, this paper demonstrates that popularity (rather than quality) inferences are the primary driver of the effect. Shelf-based scarcity is shown to have an impact in the presence of other signals, such as brand names and quality ratings, which indicates its effect may be widespread. However, its effect on preferences is…

Is there a way to quickly and easily make people be more kind and ethical?
ople are nicer after recalling memories from their childhood: Four experiments demonstrated that recalling memories from one's own childhood lead people to experience feelings of moral purity and to behave prosocially. In Experiment 1, participants instructed to recall memories from their childhood were more likely to help the experimenter with a supplementary task than were participants in a control condition, and this effect was mediated by self-reported feelings of moral purity. In Experiment 2, the same manipulation increased the amount…

A good reputation pays off
conducted the first randomized controlled field experiment of an Internet reputation mechanism. A high-reputation, established eBay dealer sold matched pairs of lots -- batches of vintage postcards -- under his regular identity and under new seller identities (also operated by him). As predicted, the established identity fared better. The difference in buyers’ willingness-to-pay was 8.1% of the selling price. A subsidiary experiment followed the same format, but compared sales by relatively new sellers with and without negative feedback. Surprisingly,…
