The dominant function is supposed to be a natural focus and strength. But are there exceptions? Can the dominant function be underdeveloped and not used enough for the person to become skillful, perhaps due to environmental or psychological influences? Can a person's own natural traits and temperament clash and interfere with the development of their dominant function (such as an introverted temperament but an extroverted dominant function, or being a Thinking type but being very emotionally sensitive)? Can periods of intense stress cause the dominant function to stop working the way it normally does and behave more compulsively, out of control, and ineffectively like the Inferior function?
