Criticizes an article by F. Landy et al (see record 1981-00274-001), which assumed that a general factor present in the intercorrelations of ratings of performance was generated by halo rating errors. A number of decision rules were used to generate an analytic procedure for extracting halo errors, correcting ratings, and interpreting factors present in the corrected correlations. A number of the decision rules, as well as the initial assumption, seem to be rules of thumb or to depend on implicit theories of ratings and not on empirical data. Reanalysis of the rating data to allow both general 2nd- and 1st-order factors to be expressed in terms of item loadings recovered the structure present in the correlation of the original ratings as well as the psychological meanings of the 1st-order factors. General factors in rating data resemble general factors in measures of human ability. It is argued that removing general factors as if they were halo rather than true score may eliminate more of the variance from rating data than is justifiable.
