Abstract:
Biases favoring the wealthy are ubiquitous, and they support and bolster vast resource inequalities across individuals and groups; yet, when these biases are acquired remains unknown. In Experiments 1 through 5 (Total N = 232), using multiple methods, we found that 14- to 18-month-old infants track individuals' wealth (Experiments 1-5), prefer and selectively help rich (vs. poor) individuals (Experiments 2 and 3), and negatively evaluate poor individuals (Experiments 4 and 5). In two subsequent experiments with 11- to 13-month-old infants (Total N = 65), however, we find no evidence of preferences for rich (vs. poor) individuals (Experiment 6) or differential evaluations of rich and poor people (Experiment 7). Together, these results demonstrate that in the second year of life, wealth emerges as a central and robust dimension of evaluation that guides social decision making.
