Psychological foundations of human status allocation

Significance Social status is a universal and consequential dimension of variation within human groups. Multiple prominent theories have been proposed to explain how status is allocated, but extant evidence is insufficient to adjudicate between their conflicting predictions. Here we show that distinctions between each theory hinge on the relative importance of four key affordance dimensions: benefit-generation ability, benefit-generation willingness, cost-infliction ability, and cost-infliction willingness. Each theory makes a different prediction about the role of each affordance in status allocation. We test these competing predictions to explain status allocations across 14 nations. We found that benefit-generation affordances uniquely predicted status allocations across nations, whereas cost-infliction affordances were weak or null competing predictors.
