Personality here refers to the general pattern of behavior, thought and action an individual will follow. However, again we run into the problem of oversimplification- one person can occupy several roles at one time- people are often complex.
One application of the idea of personality categories was developed into the Myers-Briggs Type Indicator, essentially a personality test which provides insight to which category each person fits into. These tests are occasionally used by employers as well as in the psychological field, to determine personal strong points and the best methods of learning.
The Myers-Briggs indicator incorporates 16 different personality types, which interestingly is the same number as that of the Tarot Courts. The Court cards are similar in the sense that both provide a general sense of how each person will react based on their own personality traits. We encounter the same problem in assigning people to the Court cards- that not all people fit so neatly into categories. However, these can be useful in understanding general patterns of behavior, and behavior to a large extent determines consequences.
The interpretation of these personality types comes from this site, which provides the general characteristics of each of the 16 personality types: http://www.knowyourtype.com/16_types.html The site provides a quick description of each set of factors that make up the personality type, and from these descriptions, I came up with the following set of correspondences-
Overall, this can provide some insight to the Tarot Courts- however, there are many such systems of correspondences among the Court cards. The difficulty we find in either case is that these systems represent an attempt to categorize human behavior- and the motivation for human behavior can vary as much as the people who exhibit those behaviors.
