Conflating Capacity & Authority: Why We're Asking the Wrong Question in the Adolescent Decision-Making Debate

Area of Science:

• Bioethics
• Neuroscience
• Developmental Psychology

Background:

• The capacity of adolescents to make independent medical decisions is a long-standing bioethical debate.
• Adolescents occupy a liminal space between childhood and adulthood, raising questions about their autonomy.
• Recent trends increasingly cite neuroscientific and psychological data to determine adolescent decision-making capacity.

Purpose of the Study:

• To critically evaluate the reliance on neuroscience and psychology in determining adolescent medical decision-making capacity.
• To address the conflation of decision-making capacity with decision-making authority in bioethical discourse.
• To examine the limitations of scientific data in fully resolving complex ethical questions regarding adolescent autonomy.

Main Methods:

• Analysis of arguments using neuroscientific data (MRI, fMRI) concerning adolescent brain maturity.
• Review of bioethical literature on adolescent capacity and the mature-minor doctrine.
• Conceptual analysis of decision-making capacity versus decision-making authority.

Main Results:

• Neuroscientific and psychological data are being over-relied upon to definitively answer questions of adolescent capacity.
• Conflicting interpretations of brain imaging data exist, leading to opposing conclusions about adolescent maturity.
• A critical error is conflating the concept of decision-making capacity with the legal or ethical concept of decision-making authority.

Conclusions:

• Neuroscience and psychology alone cannot fully resolve the ethical and legal questions surrounding adolescent medical autonomy.
• Distinguishing between capacity (ability to decide) and authority (right to decide) is crucial for ethical analysis.
• Over-reliance on scientific data risks oversimplifying complex bioethical issues and may lead to flawed policy recommendations.
