His research in the behavior and intelligence of various humans and animals enabled him to create a multiple-choice system and multiple-choice tool for measurement (Trewin, 2007). In 1913, Yerkes presented his device to exhibit how a multiple-choice process could successfully quantify normal and maladaptive behavior in humans. He would later go on to redesign the Stanford-Binet Intelligence so it could be frequently used as a measurement scale of human aptitude. Yerkes was appointed president of the American Psychological Association during the war were he directed a group of psychologists whose purpose was to introduce and establish psychological approaches for military service (Miles, 1946). Under his direction, his team devised ways of assessing the abilities of army recruits; developing the Army Alpha which was a verbal intelligence test and the Army Beta, a pictorial test designed for the illiterate. The irrefutable impact the tests had on the military was extensive, proving it was capable of selecting the fit recruits. The test could be administered to large groups unlike the Stanford-Binet scale, making it more efficient and easier to reproduce. The results of the test were successful and had a broad appeal which drew the attention of notable figures in the academic world. Encouraged by test results of recruits in the Army, intellectuals and elite leaders from academic circles became enthusiastic about using the IQ test for admissions to
