Children Demand an Equal Share of Worthless Objects.

Area of Science:

• Developmental Psychology
• Behavioral Economics
• Social Neuroscience

Background:

• Fairness development involves disadvantageous inequity aversion, where individuals sacrifice rewards to avoid unequal outcomes.
• The equal respect hypothesis posits that children's fairness decisions are influenced by interpersonal concerns, not solely material considerations.

Purpose of the Study:

• To investigate whether young children reject disadvantageous inequity when the unequal items are undesirable.
• To determine if interpersonal factors, such as the distributor's reasoning, influence children's rejection of inequity.

Main Methods:

• Three pre-registered experiments were conducted with 184 children aged 4-7 years.
• Children's responses to unequal offers of undesirable objects were analyzed.
• The impact of providing a reason for unequal distribution on children's rejection behavior was examined.

Main Results:

• Children as young as 4 years old demonstrated aversion to unequal distributions of undesirable objects.
• Children were willing to sacrifice high-value rewards to reject inequity involving undesirable objects.
• The likelihood of refusing unequal offers of undesirable objects decreased when a reason for the disparity was provided.

Conclusions:

• Interpersonal concerns significantly motivate the costly rejection of inequity, even when material consequences are negligible.
• Children's fairness judgments are influenced by social and relational factors beyond simple material gain.
• The findings support the equal respect hypothesis by highlighting the role of social motivations in early fairness development.
