Counterfactual reasoning in surrogate decision making -- another look

Area of Science:

• Bioethics
• Medical Law
• Philosophy of Medicine

Background:

• Incompetent patients require surrogate decision-makers.
• The Substituted Judgment Standard (SJS) traditionally guides surrogates to replicate patient choices.
• The SJS faces objections due to flawed counterfactual reasoning.

Purpose of the Study:

• To analyze amendments to the SJS using possible worlds semantics.
• To examine the moral underpinnings of substituted judgment.
• To assess the implications for accuracy and objectivity in surrogate decision-making.

Main Methods:

• Conceptual analysis of the Substituted Judgment Standard.
• Critique of existing amendments within possible worlds semantics.
• Exploration of the moral philosophy of surrogate decision-making.

Main Results:

• Existing amendments to the SJS, while addressing counterfactual reasoning, may stem from an incomplete grasp of its moral foundations.
• A deeper understanding of the moral underpinnings is crucial for refining the standard.
• This enhanced understanding has significant implications for normative assumptions about surrogate decision-making.

Conclusions:

• The traditional Substituted Judgment Standard requires re-evaluation beyond mere logical or semantic adjustments.
• Recognizing the core moral principles is essential for achieving greater accuracy and objectivity in surrogate decision-making.
• Future frameworks for surrogate decision-making should prioritize these moral underpinnings.
