If it is all 'learnable and * teachable' then there would be no such correlation. and others have referred to this without challenging it. But what studies are being referred to. A few years ago it emerged that Cyril Burt's classic twin studies were faked. (Leo Kamin demonstrated that the numbers were too good to be true and then Burt's son reported that his father had indeed faked the results.) This leaves the question whether in fact there are studies indicating a significant correlation in IQ between twins raised apart. If anyone knows of such studies I would be interested in references to them. -- Gilbert Harman Princeton University Cognitive Science Laboratory 221 Nassau Street, Princeton, NJ 08542 ghh@princeton.edu HARMAN@PUCC.BITNET
