Good leaders make a lifetime study of people - what shapes their values and character and what motivates them. This is an essential question you should try to answer when considering any field of study of major. In answering, keep in mind your purpose and duty while at West Point is to develop into a leader of character.
Competent leaders develop through an unending process of self-examination, education and experience.
People and human nature are the subject matter of a field of study or major in Psychology. Such a program of study therefore, will provide a firm foundation on which to build as you continue to develop as a leader throughout a lifetime of service to the nation. I would tell cadets interested in Psychology how helpful the department faculty is in assisting cadets to pursue what they're interested in, how friendly they are, and how applicable the study of behavioral science is to leading others. I thoroughly enjoy studying the behavior of others, how to motivate people to follow you, and how to interpret different behaviors so as to better judge what makes them tick. Leaders teach, train and counsel.
