Unfortunately Bill is too busy to weigh in here. I still haven't
untangled your simulation, but I'm skeptical that measurement error
could radically effect the results I showed (or M/H's much more detailed
results). If you're right on this, then I'd better start greeting
almost all results with greater skepticism - in the real world, what is
better measured than IQ and education?
