Young children do not perceive distributional fairness as a moral norm

Area of Science:

• Developmental Psychology
• Moral Psychology
• Social Cognition

Background:

• Existing research classifies resource distribution fairness as a moral norm.
• Fairness understanding emerges late and varies culturally, questioning its moral status.
• Previous studies did not establish the necessary moral-conventional distinction to assess fairness.

Purpose of the Study:

• To investigate whether U.S. American children perceive fairness in resource distribution as a moral or conventional norm.
• To examine developmental differences in children's classification of fairness norms.
• To compare children's judgments of fairness transgressions against moral and conventional transgressions.

Main Methods:

• Two preregistered studies were conducted with U.S. American children.
• Study 1 (N=96) aimed to establish a moral-conventional distinction.
• Study 2 (N=94) involved children aged 4, 6, and 8 rating transgression seriousness and using a forced-choice procedure.

Main Results:

• Study 1 did not yield the required moral-conventional difference.
• In Study 2, 4-year-olds equated fairness and conventional transgressions; older children (6, 8) distinguished both from moral transgressions, ranking fairness above conventional.
• Most 6-year-olds categorized fairness with moral norms, unlike 4- and 8-year-olds.

Conclusions:

• U.S. American children's understanding of fairness norms may differ from harm-based moral norms.
• Developmental shifts occur in classifying fairness, with 6-year-olds showing a clearer moral categorization.
• Fairness norms might occupy a distinct category, separate from traditional moral and conventional norms, particularly in younger children.
