Editorial commentary
Replicability tests whether a finding is robust to new samples drawn from the population. A single failed replication does not refute an original finding; systematic large-scale replication programmes (such as the Reproducibility Project: Psychology and Many Labs) provide more credible evidence of (non-)replicability. Terminology varies by field: some communities use 'reproducibility' and 'replicability' in the opposite senses.
