Glenn Daniel Wilson (born 29 December 1942) is a psychologist best known for his work on attitude and personality measurement, sexual attraction, deviation and dysfunction, partner compatibility, and psychology applied to performing arts.

After graduating MA at the University of Canterbury, Christchurch, Wilson moved to London in 1967 to study for his PhD under the supervision of Hans Eysenck, with whom he subsequently collaborated on a number of research projects and co-authored six books.

[8][9][10][11] Together with G.Knyazev and H.Slobodskaya of the Russian Academy of Medical Sciences, Wilson has researched the EEG correlates of personality and produced a theory of the evolution of brain oscillations.

[17] With Peter Fenwick and others at the Institute of Psychiatry, he studied men with normal and paraphilic interests, and how they differed in their EEG responses to erotic images in certain brain areas.

[18] Noting that men and women had different finger length patterns, Wilson introduced the 2D/4D digit ratio as a marker of exposure to prenatal testosterone in 1983.
