justifiability

Justifiability is the quality of being justifiable: capable of being defended with reasons, evidence, or principles. It concerns whether a belief, action, policy, or stance can be warranted in light of relevant considerations. Justifiability does not require absolute certainty; instead it reflects the strength and relevance of supporting reasons relative to a standard or audience.

In moral philosophy and practical decision making, a course of action is typically described as justifiable if it rests on permissible reasons, respects rights and duties, and can respond to objections. The standards of justification may vary by framework, such as consequentialist, deontological, or virtue-based approaches, but all seek defensible grounds for evaluation.

In epistemology, justification refers to rational support for beliefs. A belief is justified if it is supported by evidence, coherent with other beliefs, and formed through reliable processes. Justification is not identical to truth or knowledge; a belief can be well justified yet false.

In law and public policy, justification is the official rationale for actions or decisions. Legal justification requires adherence to statutes, precedents, and procedural rules, while policy justification argues that a measure serves legitimate interests or public welfare.

Assessing justifiability involves examining relevance, sufficiency of evidence, avoidance of logical fallacies, and resilience to counterexamples. It may require balancing competing reasons and acknowledging limitations.
