Reanalysis of a memory study originally interpreted to support J. P. Guilford's Structure‐of‐Intellect (SI) model fails to give support for the SI distinctions: (1) When capitalization on chance was limited by selecting a subsample of variables for analysis, only 3 out of 9 hypothesized factors were identified, (2) the root‐one number‐of‐factor criterion indicate that the SI model leads to a rather dramatic over‐factoring even when the factors are theoretically over‐determined, and (3) although the fit to the model is somewhat better than is expected on the basis of a completely random model, more reasonable semi‐random null‐hypotheses cannot be rejected in favor of the SI model.
