Percentage of Experimental Research in Each Psychology Subfield and the Subfield’s Mean Replication Score. Subfields with larger proportions of non-experiments (Personality Psychology, Organizational Psychology and Clinical Psychology) have a propensity for higher average replication scores. An exception is Developmental Psychology. It has the lowest average replicability and is mostly non-experimental. The discrepancy may be accounted for by the tendency of Developmental Psychology to study participants over their lifespans, from infancy to adulthood, which presents unique data collection challenges (57).
