A personality profile that is a bit more helpful than "Which Harry Potter character are you?"
The Enneagram is a personality profile consisting of nine personality types. I find it helpful in creating realistic characters, in that it is not a static system, but one that details the way that certain personalities evolve, devolve, or change in circumstances of stress, chaos, and breakdown or growth, development, acceptance, and wholeness. "In other words, different situations will evoke different kinds of responses from [a specific] personality."* Each of the nine types can have some aspects of its neighboring type (called a wing). This results in the 27 types below (listed with a title that is sometimes helpful, sometimes a bit misleading). The descriptions of the 9 basic types may be found below the list of the 27.
There is no right or wrong, good or bad personality type. Because the system is dynamic, you may find a Type 1 (The Idealist) that is "extraordinarily wise and discerning...Conscientious with strong personal convictions: they have an intense sense of right and wrong, personal religious and moral values. Wish to be rational, reasonable, self-disciplined, mature, moderate in all things. Extremely principled, always want to be fair, objective, and ethical: truth and justice primary values. Sense of responsibility, personal integrity, and of having a higher purpose often make them teachers and witnesses to the truth." Conversely, a more depraved or immature Type 1 Idealist could be "highly dogmatic, self-righteous, intolerant, and inflexible. Begin dealing in absolutes: they alone know "The Truth." Everyone else is wrong: very severe in judgments, while rationalizing own actions. Become obsessive about imperfection and the wrong-doing of others...Become condemnatory toward others, punitive and cruel to rid themselves of 'wrong-doers.'"
