Abstract

Abstract: The positive manifold hypothesis is closely related to intelligence research and to factor analysis. It comes in different versions: (1) the inter-correlations of a set of test items are all positive and (2) the configuration of vectors representing these test items in common factor space can be rotated so that the loadings of all vectors are positive. We here show that positive intercorrelations are only a necessary but by far not a sufficient condition in case of more than two factors.
