First, the study of interpersonal expectancy effects requires an examination of the expectancy-mediator-changes (B-C-D) chain in toto. Harris and Rosenthal's meta-analytic exercise fails to substantiate such a chain, and also fails to enhance understanding of the subtle and unwitting nature of the expectancy-mediator (B-C) and the mediator-changes (C-D) links. Second, mixing studies of uneven quality in a meta-analysis still appears to be a cause for concern.} }
