Incomplete preferences and rational framing effects

Area of Science:

• Decision Theory
• Cognitive Science
• Philosophy of Mind

Background:

• The principle of description invariance in decision theory assumes rational preferences must be complete.
• The completeness axiom, a cornerstone of rational choice theory, is increasingly debated.
• Framing effects, where presentation influences choices, challenge the notion of stable rational preferences.

Purpose of the Study:

• To critically examine the normative assumption of completeness in rational preferences.
• To explore how rejecting the completeness axiom can accommodate rational framing effects.
• To situate Bermúdez's critique of framing within a broader challenge to completeness.

Main Methods:

• Conceptual analysis of normative principles in decision theory.
• Philosophical argumentation regarding the completeness axiom.
• Literature review of existing critiques on framing effects and rational choice.

Main Results:

• The completeness axiom is normatively dubious and not essential for rational decision-making.
• Rejection of completeness provides a framework for understanding rational framing effects.
• Bermúdez's challenge to framing can be strengthened by a wider critique of completeness.

Conclusions:

• The standard normative view of framing requires re-evaluation by questioning preference completeness.
• Decision-making models should consider scenarios where preferences may not be complete.
• A broader critique of completeness offers new perspectives on rationality and framing.
