This working paper presents the results of an indirect assessment of the personality of U.S. senator Kamala Harris, Democratic vice-presidential nominee in the 2020 U.S. presidential election, from the conceptual perspective of personologist Theodore Millon.

Psychodiagnostically relevant data about Harris were collected from biographical sources and media reports and synthesized into a personality profile using the Millon Inventory of Diagnostic Criteria (MIDC), which yields 34 normal and maladaptive personality classifications congruent with DSM-III-R, DSM-IV, and DSM-5.

The personality profile yielded by the MIDC was analyzed in accordance with interpretive guidelines provided in the MIDC and Millon Index of Personality Styles manuals. Harris’s primary personality pattern was found to be Dominant/asserting (a measure of aggressiveness), complemented by secondary Ambitious/confident and Outgoing/congenial patterns — measures of narcissism and extraversion, respectively.

In summary, Harris’s personality composite can be characterized as high-dominance charismatic — charismatic by virtue of the elevated Ambitious–Outgoing amalgam.

Dominant individuals enjoy the power to direct others and to evoke obedience and respect; they are tough and unsentimental and often make effective leaders. Ambitious individuals are bold, competitive, and self-assured; they easily assume leadership roles, expect others to recognize their special qualities, and sometimes act as though entitled. Outgoing individuals are dramatic attention-getters who thrive on being the center of social events, go out of their way to be popular with others, and have confidence in their social abilities.

Harris’s major personality strengths in a political role are her confident assertiveness and personal charisma. Her major personality-based shortcoming is likely to be a predisposition to occasional lapses in emotional restraint or self-discipline.


The research was conducted at the Unit for the Study of Personality in Politics (USPP), a collaborative faculty–student research program in the psychology of politics at St. John’s University and the College of St. Benedict in Collegeville and St. Joseph, Minnesota, directed by Aubrey Immelman, Ph.D., associate professor of psychology, who specializes in the psychological assessment of presidential candidates and world leaders.
