The Development of a Scarcity Bias.

Area of Science:

• Developmental Psychology
• Cognitive Science
• Behavioral Economics

Background:

• Adults exhibit attraction to rare objects, often linked to resource scarcity, self-identity, or market perceptions.
• Understanding the origins of the scarcity bias is crucial for developmental and economic psychology.

Purpose of the Study:

• To investigate the developmental emergence of the scarcity bias in human infants and young children.
• To determine the age at which children begin to prefer scarce resources over abundant ones.

Main Methods:

• Three studies were conducted with 129 participants, including 11- and 14-month-old infants and children aged 3 to 6 years.
• Participants chose between a set of identical abundant items and a single scarce item.
• Methodological modifications were employed to assess choice behavior in different age groups.

Main Results:

• A significant preference for scarce resources was not observed in infants.
• A robust scarcity bias emerged specifically in 5-year-old children.
• The preference for scarcity developed before children could comprehend abstract market forces.

Conclusions:

• The scarcity bias is not innate but develops during early childhood.
• The emergence of the scarcity bias predates the understanding of social and market influences.
• This developmental trajectory offers insights into the cognitive underpinnings of resource valuation.
