Rensis Likert (5 August 1903–3 September 1981) was an American administrator and organizational psychologist based at the U.S. Department of Agriculture, then at the Institute for Social Research at the University of Michigan. He is best known for survey research methods and for the Likert Scale, a psychometric scale commonly involved in research using questionnaires. Likert received his B.A. in economics from the University of Michigan in 1926. The social sciences of the 1920s were highly experimental and incorporated many aspects of modern psychology. In 1932 Likert received a Ph.D. in psychology from Columbia University.
