  1. In a recent paper Peter Urbach ([1974]) discusses what he calls progress and degeneration in the IQ debate. Urbach's paper contains in my judgment errors of fact, errors in the interpretation of data, and conceptual misunderstandings.
  2. I should like to comment on these, first stating my own position on the general issue. It is this: the controversy about heritability of IQ, in particular as it relates to social class and other sub-population differences, is scientifically barren, because the questions are posed in such a way as to admit of no definite, or even 'probabilistic' answer. The 'debate' is being conducted in thoroughly old-fashioned terms which confuse the real issues.
