Intersubjective Verifiability

Intersubjective verifiability is the capacity of a concept to be readily and accurately communicated between different individuals ("intersubjectively"), and to be reproduced under varying circumstances for the purposes of verification. It is a core principle of empirical, scientific investigation.

Although there are areas of belief that do not consistently employ intersubjective verifiability (e.g., many religious claims), intersubjective verifiability is a near-universal way of arbitrating truth claims used by people everywhere. In its basic form, it can be found in colloquial expressions, e.g., "I'm from Missouri. Show me!" or "Seeing is believing." The scientific principle of replication of findings by investigators other than those that first reported the phenomenon is simply a more highly structured form of the universal principle of intersubjective verifiability.
