Abstract
The paper reviews many objections to meta-analysis, both in principle, and in particular, as practiced by its originators. Particular attention is given to the most widely cited application of meta-analysis: to the facts of psychotherapy. It is suggested that the claims to inclusiveness and objectivity, made for these analyses, are not supported by the evidence, and that the conclusions drawn from the evidence surveyed are incompatible with the results of the analysis on which they are supposed to be based. It is further suggested that no pseudo-objective computerized technique can substitute for the scientific insight and theoretical acumen of the investigator. Indeed, for most purposes the simplistic scoring systems of meta-analysis are not only useless, but may be counterproductive. It is precisely in those areas where there is most disagreement that these methods are least applicable.
