Humphrey's Attenuated Test of Spearman's Hypothesis.

Jensen, Arthur R.

Intelligence, v9 n3 p285-89 Jul-Sep 1985

The author refutes Humphrey's test of the Spearman hypothesis. A fair test requires that Black and White samples not be selected on any g-correlated variable, including socioeconomic status. Humphrey's factor analysis on test-score means of demographic groups, rather than on individuals, inflates g loadings and biases results. (LMO)
