Gifted is also binary. Neither
measure has a national
standard. Worse, they are
not disjoint. That means a
math prodigy who is also
paraplegic will be counted
twice. Note that many
children with Asperger's
Syndrome routinely have IQs
that are so high they are
difficult to measure reliably,
yet because there is often an
accompanying lack of social
awareness, they are counted
as disabled.
