Abstract

Replication is already mainstream in areas of psychology that use small-N designs. Replication failures often result from weak theory, weak measurement, and weak control over error variance. These are hallmarks of phenomenon-based research with sparse data. Small-N designs, which focus on understanding processes, treat the individual rather than the experiment as the unit of replication and largely circumvent these problems.
