Jack -- Yes, I know, and that's why I've given the 35-50% statistic the benefit of the doubt for most of my life, and it certainly remains a significant statisitic filter for those people I've met in social and accademic settings.

But then I think about all those with cerebral palsy who shared space with me on children's hospitals wards (where we were grouped together according to which orthopedic surgery we needed, which was totally independent of mental capability), or at the summer camp I went to, which served both severely mentally and physically disabled people. And then, there are other clients of my aide who happen to have cerebral palsy, and with whom I have no other social interaction in common, and some of whom have been homeschooled because their level of physical disability is too severe for the public school to handle.

And then, there are news stories I come across that happen to feature someone with cerebral palsy -- stories of the sort where, if the person being written about were intellectually impaired, that would certainly be mentioned to heighten the "specialness" factor of the story.

And in all my 40 years of having a social life independent of my nuclear family, I have only heard of one person with CP who was, in fact, mentally handicapped.

And while I grant that there is a higher risk of cognitive impairment in all children born premature, or with other neonatal risk factors, and that includes people with CP, I do know that I've seen more people labeled as mentally retarded than actually are so I am skeptical that the corelation is as high as sites like the WebMD claim.
