The evolution of spite entails actors imposing costs on ‘negative’
relatives: those who are less likely than chance to share the actor’s
alleles and therefore more likely to bear rival alleles. Yet, despite a
considerable body of research confirming that organisms can recognise
positive relatives, little research has shown that organisms can recognise
negative relatives. Here, we extend previous work on human phenotype
matching by introducing a cue to negative relatedness: negative
self-resembling faces, which differ from an average face in the opposite
direction to the way an individual’s own face differs from the average.
Participants made trustworthiness and attractiveness judgements of pairs
of opposite-sex positive and negative self-resembling faces. Analyses
revealed opposing effects of positive and negative self-resembling faces
on trustworthiness and attractiveness judgements. This is the first clear
evidence that humans are sensitive to negative relatedness cues, and
suggests potential for the adaptive allocation of spiteful behaviour.
