MRA: A tradition in management development since 1954.

In the late 1940's, there was a concerted effort to bring psychometrics to bear in the workplace. There was also a focus on accommodating the natural differences among healthy people, rather than building a theory based on psychopathology, as Freud and Jung had done. In 1926, Psychologist William Marston published his revolutionary book, The Emotions of Normal People, which motivated Walter E. Clark and others, to develop a more accurate personality typology specifically for business. It was based on four key behavioral traits which can be objectively measured, yielding a high correlation with specific workplace behaviors.

MRA Founder Charles Menzies had worked with Clark, but reinvented the process and re-did the research to make it a more comprehensive and powerful management tool, in addition to an accurate employee selection method.

The popularity of MRA's proprietary profiling instruments quickly grew due to their accuracy (92.2%), ease of use, and the growing complexity of hiring. Charlie Menzies retired in 1985 after introducing MRA to a broad array of industries. Today, under the leadership of Laurence Sartor, Ph.D., Charlie Menzies' excitement, dedication and tradition continue in an expanded of profiling tools and support services.
