Sounds suspiciously like science qua 'the critical approach', a la Popper. Moreover: _all_ methods are fallible, and so are the results obtained. This fact produces, for some, a progressive 'problem-shift' from the (misconceived) problem of establishing infallible methods and results to the problem of critically assessing methods and results in the light of the ever-present possibility of error, error which may arise from hitherto unsuspected sources. This shift is not merely semantic but involves a profound change in attitude and approach. <snip> > Back to the storm. Mike culled sections from Wikipedia > about black-white comparisons.

Of course, it _could_ be used as fuel for a racism campaign (the energy sources for such campaigns are in no clear and present danger of depletion). As Eric points out, for example, it could be used as fuel for an assault on efforts to better educate whites. But then nothing in policy or ethical terms follows logically from the science here: even if it were reliably shown that whites and blacks were harder to educate than Asians, this could be used as fuel for directing more help to whites and blacks rather than less. While it may be amusing to witness how debates on I.Q. are driven by ideological falsehoods and riven with 'is/ought' confusions, perhaps the 'science' of understanding human intelligence may yet prove its worth if it furthers efforts to improve education. > Regards, > Eric > IQ: 152 Ah.

Popper makes two important points about I.Q. in 'The Self and Its Brain'. The first, more commonplace point is that with I.Q. there is always the question of what we should be measuring and why, and the search for a single-value measure of I.Q. is as dubious as the search for a single-value measure of the quality of soil - quality depends on what purpose we want served. The second point is that we should be open to the possibility that there is little _important_ correlation between I.Q. and the kind of creative brilliance with producing/discovering World 3 entities that marks out a Mozart, Bach or Einstein. The latter truimvirate may not have had anything like the highest I.Q.s whereas Popper claims he knew at least one I.Q. genius who was a complete "blockhead". Human knowledge does not advance much by people completing I.Q. tests - it depends on people producing/discovering World 3 entities such as problems and their possible solutions.
