Whose welfare and interests matter from a moral perspective? This question is at the center of many polarizing debates, for example, on the ethicality of abortion or meat consumption. A widely cited hypothesis holds that attributions of moral standing are guided by which mental capacities an entity is perceived to have. Specifically, perceived sentience (the capacity to feel pleasure and pain) is thought to be the primary determinant, rather than perceived agency (the capacity to navigate the world and social relationships) or other abilities. This has been described as a general feature of moral cognition, but the evidence for this is mixed and overwhelmingly based on Western participants. Here, we examined the link between attributions of mind and moral standing across six culturally diverse countriesâBrazil, Nigeria, Italy, Saudi Arabia, India, and the Philippinesâusing a sample of 1,255 participants (aged 18â74 years old) who were recruited via the online platform Toloka. In every country, entitiesâ moral standing was most strongly related to their perceived sentience.
