Verifiability is a core principle of science

Abstract

Scientific knowledge is supposed to be verifiable. Replications promote verifiability in several ways. Most straightforwardly, replications can verify empirical claims. Replication research also promotes dissemination of information needed for other aspects of verification; creates meta-scientific knowledge about what results to treat as credible even in the absence of replications; and reinforces a broader norm of scientists checking each other's work.
