David Lubinski

David J. Lubinski is an American psychology professor known for his work in applied research, psychometrics, and individual differences. His work (with Camilla Benbow) has focussed on exceptionally able children: the nature of exceptional ability, the development of people with exceptional ability (in particular meeting the educational needs of gifted children to maximise their talent). He has published widely on the impact of extremely high ability on outputs such as publications, creative writing and art, patents etc.

Lubinski has argued against the "threshold hypothesis" which suggests that a certain minimum of IQ might be needed, but higher IQ did not translate into greater productivity or creativity. Instead, he has argued that higher intelligence leads to higher outcomes with no apparent threshold or dropping off of its impact. Provided by Wikipedia
