Insights
Children aged 4-9 years intervene against gender pay inequality, regardless of its direction. This tendency to promote equality strengthens with age, even in societies with existing pay gaps.
Area of Science:
- Developmental Psychology
- Social Psychology
- Behavioral Economics
Background:
- Gender pay inequality is a persistent societal issue with complex origins.
- Understanding the developmental trajectory of fairness and equality is crucial for addressing social disparities.
- Cross-cultural research is vital to discern universal patterns from culturally specific influences on social cognition.
Purpose of the Study:
- To investigate the developmental origins of intervention against gender-based pay inequality in young children.
- To examine children's responses to gender pay inequality across two distinct cultural contexts (United States and Peru).
- To determine if children's intervention tendencies are influenced by the direction of pay inequality and age.
Main Methods:
- Children aged 4-9 years from the United States (N=123) and Peru (N=115) participated in the study.
- Participants were presented with hypothetical scenarios depicting gender-based pay inequality.
- Children had the option to intervene, at a personal cost, to redistribute earnings, allowing for the assessment of their preference for equality versus biased intervention.
Main Results:
- Both boys and girls across both countries intervened to counteract gender pay inequality.
- Intervention against inequality occurred irrespective of whether men or women were disadvantaged.
- The propensity for children to intervene against gender pay inequality increased significantly with age.
Conclusions:
- Young children demonstrate a robust inclination to uphold equality, even when faced with societal norms reflecting gender pay disparities.
- The findings suggest an innate or early-developing preference for fairness that can override learned biases.
- Intervention against gender pay inequality is a developmental phenomenon that strengthens through childhood, indicating a growing capacity and willingness to promote equity.
Abstract:
We explore the developmental origins of intervention against gender-based pay inequality in 4- to 9-year-old children in the United States (N = 123; Study 1) and Peru (N = 115; Study 2), two countries characterized by different norms surrounding gender pay equity. We presented children with scenarios that featured gender-based pay inequality, and they could intervene at a cost to redistribute the earnings. We examined whether children favor equality or show gender bias in intervention depending on the direction of gender pay inequality. Across both societies, both girls and boys intervened against gender inequality regardless of its direction, a tendency that grew stronger with age. These findings suggest that despite developing in societies with existing gender pay inequalities, children strongly privilege equality.
