Explanation
An inference that holds under normal assumptions but can be retracted by additional information. Reasonable inference is revealed as a dynamic network, not merely as an irrefutable deduction.
Example
Birds usually fly; Tweety is a bird; therefore, Tweety flies—as long as nothing to the contrary is known.
Counterexample
A formally valid deductive inference is not invalidated by new facts.
Distinction
Distinction from abduction: A formally valid deductive inference is not rendered invalid by new facts.
Effect on thought and perception
Reasonable inference is revealed as a dynamic network, not merely as an irrefutable deduction.
Resonance
Defeasible inference makes a directed relationship perceptible: Reasonable inference is revealed as a dynamic network, not merely as an irrefutable deduction.
