Maintaining reciprocal relationships is challenging, as there is uncertainty both about our partner's intentions and their competences. When investing in a partner, we are making two bets: that they are motivated to reciprocate and that they are able to do so. There is compelling evidence that humans have evolved cognitive mechanisms to inform the first bet. People routinely detect, avoid or even punish cheaters and free-riders in reciprocal relations (Cosmides & Tooby, 1992; Delton, Cosmides, Guemo, Robertson, & Tooby, 2012). We also take motivations into account when making decisions about who to help (Petersen, 2015). The evidence is less clear when it comes to the second bet regarding abilities and competences. Research in psychology gives the impression that people are unskilled at distinguishing between competent and incompetent social partners. In a laboratory experiment, Delton and Robertson (2012) described targets who either contributed to the group's food pool or not and found no evidence that this information led to categorization. In a similar experiment, van Leeuwen, Park & Penton-Voak (2012) presented targets who varied both in their morality and competence, finding that respondents spontaneously categorized the targets along morality but not competence. Focusing on motivational systems related to these two dimensions, Petersen and colleagues found that incompetence does not trigger strong emotions, whereas a lack of motivation (intention) to cooperate does (Petersen, Sznycer, Cosmides, & Tooby, 2012; Petersen & Aarøe, 2013). In sharp contrast to these findings, however, research in political science on the evaluation of political leaders suggests that competence is a key character trait shaping evaluations (
