Scott was granted extended leave of absence from Northwestern from 1916-1918 which enabled him to serve as Director of the new Bureau of Salesmanship at the Carnegie Institute of Technology.

Scott will be recalled as the president who transformed Northwestern into a financially stable, administratively consolidated, and academically respectable university.

Along with Alfred Binet and Walter Van Dyke Bingham, Scott applied the military's need for "quick thinking" recruits when developing "intelligence."

Unlike Hugo Münsterberg and Harry L. Hollingworth, Scott disregarded features in the workplace like fatigue and stimulants on the worker.

Both men had elitist views about the use of science to organize society, but Scott believed that habit dictated social order.

Rather, he was motivated by practical social needs, allowing him to rephrase Galton's human variation analysis as "personal" differences.

Before World War I, Scott developed tests for any variety of mental functions that business clients specified as most desirable among prospective employees.

Scott, Galton, and Binet all sought to facilitate the institutional placement of persons by objectifying evaluations and assuming that mental ability was innate.

[3] The nature of applied psychology was too demanding for Walter Dill Scott to continue his research on human behavior, which led his focus on establishing his own theories.

According to Scott, advertisements are utilized most effectively when large numbers of the right kind of people see them in a publication which adds confidence and recommends it favorably to prospective customers.

Successful writers of advertisements had to possess technical knowledge, a creative imagination, and the ability to give precise descriptions of things.

The concept of suggestibility eventually was phased out among scientific psychologists; however, the notion that underlying human behavior influences consumer decisions is still preserved.

The AIDA contemporary model of marketing has roots in Scott's writings, which describe what usually occurs when a consumer engages with an advertisement.

[5] Scott wanted to make the marketplace and workplace more efficient through the rationalization of consumer and worker activities, especially by appealing to the self-interest of shoppers and laborers.

Scott solved the problem of selecting not only officers but also men whose aptitudes would fit them for training as specialists and technicians of many kinds.
