OK, let's look at Greta's research population - I believe she is
looking at a very small segment of the CP population - 6 to 8-year-
olds, and probably has a narrow sample to work with.  It *is* rather
difficult to get a true sampling of such a research population if one
is limited by geographic location and also dependent on responses
from email lists, etc.  (i.e., only those parents with internet
access would be able to respond, not every parent of a CP child).
It's the same problem with obtaining a truly random population
sampling from a phone book -- that is, only those with listed phone
numbers would have been called (although nowadays that's gotten
around by using automatic diallers).

In any case, I consider the Stanford-Benet IQ only one indicator of
how well a person will do in life; in fact, in the past few  years,
social scientists have talked about several types of IQ's, not just
the Stanford-Benet, which is a limited measure of how well we retain
knowledge.  I can't remember offhand how many there are, but I do
recall reading that two of the most important are an emotional
ability and a resilience ability, and that all these quotients are
best studied in conjunction with each other as how well an individual
functions in society, not as isolated indicators.
