defeasibility

Defeasibility refers to the condition where a claim or rule can be overturned or invalidated by some new evidence or information. In reasoning or law, it means that conclusions or rules are not absolute; they can be defeated or modified if specific factors arise. For example, a rule might generally apply, but if certain exceptions or evidence are presented, it can be disregarded or altered. This concept allows for flexibility and context-awareness, ensuring that decisions remain accurate and fair by considering new or changing information that might challenge initial assertions.
