Most species of social insects have singly mated queens, but in some species each queen mates with numerous males to create a colony whose workers belong to multiple patrilines. This colony genetic structure creates a potential for intracolonial nepotism. One context with great potential for such nepotism arises in species, like honey bees, whose colonies reproduce by fissioning. During fission...

In a recent study, we found a negative association between psychopathy and violence against genetic relatives. We interpreted this result as a form of nepotism and argued that it failed to support the hypothesis that psychopathy is a mental disorder, suggesting instead that it supports the hypothesis that psychopathy is an evolved life history strategy. This interpretation and subsequent argume...

Nepotism, where individuals are favored based on their connections rather than qualifications, corruption accountability, also undermine Both racism prevent the most qua...

Nepotistic practices are detrimental for academia. An analysis of shared last names among academics was recently proposed to measure the diffusion of nepotism, the results of which have had a huge resonance. This method was thus proposed to orient the decisions of policy makers concerning cuts and funding. Because of the social relevance of this issue, the validity of this method must be assess...

We develop an experimental test to distinguish between discrimination against and nepotism. The experiment compares the behavior toward individuals of different groups with the behavior toward anonymous individuals (those having no clear group affiliation). Not only is the distinction between the different types of discrimination important for the study of social segmentation, but it has intere...
