And it is worse when they are under stress - worse in a debate where the stakes are high, worse in an interview when the introvert hasn't had sufficient time to reflect on the question. Introverts often only know what they really think on a topic after reflecting on it. Our inferior function is the most undeveloped part of ourselves. For the introverted intuitive whose inferior is extraverted sensing his greatest problem is remembering facts. Type theory tells us our inferior function is less under conscious control than our dominant function.
Willpower is no use in improving it.
It tends to be very slow. For an introverted intuitive doing something that requires extraverted sensing will often require more time than it would for someone whose dominant function was sensing. So if I am right about Gore's dominant function and inferior function we haven't seen the last of his getting the facts and the details wrong. Our dominant function works in the world that is the most important to us, that we are most interested in - the inner world for introverts, the outer world for extraverts. For introverts what their outer world sees is their second best function, their auxiliary.
