Carl Iver Hovland: Statesman of Psychology, Sterling Human Being

Yale psychologist Carl Iver Hovland made singularly important contributions to experimental, social, and cognitive psychology (focusing, respectively, on human learning, attitude change, and concept acquisition). In the process, he worked unremittingly “to improve the standards and quality of research in psychology and related fields,” earning (in the words of one of his long-time coworkers) universal recognition as a “statesman of the social sciences” (Janis, 1968, p. 530).
