What scientific evidence is there against the urn-out myth?
“The man most responsible for changing this belief was Lewis M. Terman. Between 1900 and 1920 he was able to carry out a study of about a hundred gifted children, and his observations convinced him that many of the traditional beliefs about the gifted were little more than superstitions. To confirm these observations, he obtained a grant from the Commonwealth Fund in 1922, and used it to sift a population of more than a quarter of a million children, selecting out all those with IQs above 140 for further study. That group has been monitored continuously ever since.
