A comparison between the OCA and
earlier psychometric tests

Comparing the graphs produced by the psychometric graphs used by the Dianetics Foundations with that produced by the Church of Scientology's Oxford Capacity Analysis, it soon becomes apparent that many features of the former appear in the latter. It seems reasonable to suggest that the OCA chart was, in effect, devised by adding together elements of its predecessors. Take a careful look at the following:
