Is probability the only coherent approach to uncertainty?

Area of Science:

• Epistemology
• Philosophy of Probability

Background:

• The prevailing view in many fields suggests probability theory is the sole rational framework for quantifying uncertainty.
• This perspective often assumes a specific, potentially restrictive, view of what constitutes uncertainty.

Purpose of the Study:

• To critically examine the argument that probability theory is the only sensible approach to uncertainty.
• To identify and evaluate the underlying assumptions of this argument.
• To propose alternative conceptualizations of uncertainty.

Main Methods:

• Logical analysis of the argument for probabilistic uncertainty.
• Identification and critique of controversial assumptions regarding the nature of uncertainty.
• Development of conceptual examples illustrating non-probabilistic uncertainty.

Main Results:

• The argument for probability theory's exclusivity relies on contentious assumptions about uncertainty.
• These assumptions are not universally applicable and can be reasonably rejected.
• Non-probabilistic forms of uncertainty exist and can be meaningfully discussed.

Conclusions:

• The claim that probability theory is the only sensible way to deal with uncertainty is not universally valid.
• A broader understanding of uncertainty is required, encompassing non-probabilistic forms.
• Further research into the nature and management of diverse uncertainties is warranted.
