Two well documented but still neglected blind spots of often-used study designs limit a researcher’s ability to make inferences about psychological phenomenon. First, typical focus on effects conditions at the group level and are not able assess extent which characterize each participant in study. This spot can lead erroneous (or incomplete) conclusions manipulations both for given level. Second, commonly used research often use only limited sample stimuli, constraining particular stimuli. non-replication when different stimuli used. We propose that Highly-Repeated Within-Person (HRWP) approach helps mitigate these limitations. Using anti-smoking messages, we illustrate how HRWP alert researchers group-level may apply all any) participant, quantifies heterogeneity across people, increases confidence regarding generalizability effects. discuss help conceptualize issues replicability new light.
