Penrose's "Colchester Survey" of 1938 was the earliest serious attempt to study the genetics of learning disability. He found that the relatives of patients with severe disability were usually unaffected but some of them were affected with similar severity to the original patient, whereas the relatives of patients with mild disability tended mostly to have mild or borderline disability

In British psychiatry, the so-called 'Penrose's Law' states that the population size of prisons and psychiatric hospitals are inversely related, although this is generally viewed as an oversimplification. He was also a lead figure in the Medical Association for the Prevention of War in the 1950s.
