Children Value Animals More Than Adults Do: A Conceptual Replication and Extension.

Recent psychological research finds that U.S. American children have a weaker tendency than U.S. American adults to value humans more than animals. We aimed to conceptually replicate and extend this finding in a preregistered study (N = 412). We investigated whether 6- to 9-year-old Polish children (Study 1a) are less likely to prioritize humans over animals than Polish adults are (Studies 1b and 1c). We presented participants with moral dilemmas where they had to prioritize either humans or animals (dogs or chimpanzees) in situations that involved harming (i.e., a trolley problem) or benefiting (i.e., giving a snack). We found that Polish children prioritized humans over animals less than Polish adults did. This was the case both in dilemmas that involved preventing harm and in dilemmas that involved providing snacks. Both children and adults prioritized humans over chimpanzees more than humans over dogs.
