Clinical and statistical prediction: a retrospective and would-be integrative perspective

One of the early participants in the clinical-statistical controversy describes his effort to mediate the dispute and to direct attention to the underlying issues, to most of which the box scores were irrelevant. A previously undiscussed undercurrent of the controversy is the conflict between different metaphysical world views, the history of which for the past few hundred years is quickly sketched. The mechanist metaphysics of behaviorism, which has long been dominant in American mainstream psychology, favors objective and statistical approaches and discourages interest in judgement, an issue that nevertheless refuses to go away. Systems philosophy is proposed as an integrative alternative.
