Illustrative Case: West Point

The military is a human resource management arena of enormous challenge and complexity, comparable to and even eclipsing the processes of big business. After all, military leadership involves workforces (servicemen and women) which number in the hundreds of thousands, spread over broad job types and geographies, and involving considerable motivational and coordination challenges. They require every type of HR process and intervention, from acquisition to payment to training.
The United States Military Academy at West Point prides itself on being one of the world’s best training institutions for young officers. Their Corps of Cadets currently numbers over 4,500, and each year the academy graduates approximately 1000 cadets who become second lieutenants in the U.S. Army. The academy must straddle ground between being an educational and a workplace training institution, as it must produce ready officers.
West Point is no middling institution – it stands on its own as a significant training body. U.S. News & World Report have in past years lauded it as the Best Public Liberal Arts College in the country, Forbes.com recently pronounced West Point as the Best Public College or University in America for undergraduate education (#7 on the Forbes list of “America’s Top Colleges for 2013”), and The Princeton Review nominated it as one of the 100 Best Value Colleges for 2009. All cadets receive a Bachelor of Science degree, and are fully prepared to meet the intellectual requirements of a leader in today's U.S. Army.
Selection into such a program is a crucial part of the process: after all, the academy must preselect people whom they already believe to have the potential to be good officers, and who will be able to handle the strenuous combination of high-class academic as well as military training.
Psychological assessments help in such a selection challenge, and are also used extensively in the corporate world. With this in mind, Bartone, Eid, Johnsen, Laberg and Snook (2009) undertook a study among West Point cadets to investigate various psychological predictors of “leader performance.”
Specifically, the study evaluated the influence of psychological hardiness, social judgment, and the “Big Five” personality dimensions (neuroticism, extroversion, openness, agreeableness, and conscientiousness) on leader performance. They studied cadets in two different contexts: summer field training (the military training component of the program) and academic study. Supervisor ratings of leader performance, aggregated over four years, were the outcome of interest.
The study employed a statistical technique called regression, which we will study in this chapter. After taking into account differences due to general intellectual abilities, the results showed that cadets who are more extroverted, more hardy, and who had a trend for a variable called ‘social judgment’ (see the original article for a definition), performed better in the summer field training environment. In the context of academic study, more successful cadets were those showing traits such as conscientiousness and hardiness. Certain other psychological traits that we might think predict officer performance, such as openness, did not seem to have an impact.
How can the academy use the results? First, they can pretest applicants on these characteristics, and use the results to help them select cadets. Secondly, they might tailor individual development of cadets by identifying personality issues that could undermine potential in the various areas, and attempt to help the person overcome these issues.
In this case, we saw an outcome variable that corresponds with operational outcomes, and predictors that lie within individuals. The skills that enable the analyst to link variables in this way are of use in a great number of HR situations. The regression technique is used in thousands of ways throughout the business world.
