With regard to collegedad13’s post #438, pittsburghscribe posted a comment that some research has indicated that the adjustment difficulties for severely gifted people tend to be greatest between the ages of 4 and 9. I think the difficulties probably taper off, but are not gone, up to age 15 or 16, maybe even older. The comment about golf in #438 indicates social adjustments that can be made by teens and adults. A few 4 year olds do play golf (Tiger Woods), but that’s a very small group.
hebegebe is right from what I have read, that the IQ’s in the 165+ range do not follow a normal distribution, and there are many more such people than one would predict from a normal distribution.
