| Abstract: | Conducted a quantitative meta-analysis of 21 realistic job preview (RJP) experiments. Eight attitudinal or behavioral criteria were used to assess the effects of RJPs, and for 4 of these, the variance around the mean effect size could be explained methodologically as a result of sampling error, differences among studies in measurement reliability, or as a result of a single outlier study. Only 1 moderator was found, with the type of medium used to present the RJP moderating the RJP/performance relation. Considering all 8 criteria together, the average amount of variance attributable to sampling error alone is 74.2%. Thus, recent speculation about the possible moderating effects of personal or situational variables seems unwarranted. The direction of the effects was generally consistent with previous thinking. That is, RJPs tended to lower initial job expectations while increasing self-selection, organizational commitment, job satisfaction, performance, and job survival.
