title: Reflections on the origins of meta-analysis.
abstract: In this interview, we discuss my early uses of meta-analytic procedures, first to combine p-values and then to combine effect sizes as well. My interest in quantifying the magnitude and the statistical significance of the effect of interpersonal expectations probably grew out of the following: (1) a long-held interest in the concept of replication and (2) a series of controversies over the very existence of any effect of interpersonal expectations held, for example, by psychological experimenters, classroom teachers, and leaders of various organizations.
