Harry Potter, J. K. Rowling

Dominant Extroverted Sensing (Se): Bagman used to be a big Quidditch star, owing to his thrill-seeking nature. He played a position (Beater) that requires balance as well as arm strength. Even after leaving the world of professional Quidditch, Bagman still prefers to live life on the edge. He does this mainly by betting; he is a compulsive gambler, especially about Quidditch matches and other sporting events, and he borrows large sums of money in order to cover his gambling debts. Bagman is the announcer at both the Quidditch World Cup and the Triwizard Tournament, owing to two things: his eye for details and his liking for attention.

Auxiliary Introverted Thinking (Ti ): Bagman has little regard for rules of any kind. He goes against the law whenever he can get away with it (dressing in wizarding fashion in situations when muggle clothing is required, placing a bet that Harry will win the Triwizard Tournament), and in fact, he has such ignorance of the rules of the Triwizard Tournament that he relies on Mr. Crouch to make a rules-based judgment. (He’s not trying to achieve anything by breaking rules, he’s just trying to have fun.) Bagman gives odds on most bets he makes based on his own analysis of their soundness.

Tertiary Extroverted Feeling (Fe): Although Bagman is a bungler who is prone to illegalities, he manages to the Head of the Department of Magical Games and Sports, because people like him personally. Bagman can say and do much to get on people’s good side (e.g. securing Top Box tickets at the Quidditch World Cup for the Weasley family). When Bagman stood trial for activity connected to Lord Voldemort, nobody (except the legalistic Mr. Crouch) took the trial seriously.

Inferior Introverted Intuition (Ni): Bagman is unable to envision the future consequences of his actions. He can’t see why, say, getting himself into debt through gambling, then borrowing money from goblins to pay off this debt, and then pinning his entire financial future on Harry winning the Triwizard Tournament is a bad idea. He also doesn’t read between the lines; as a result, he can easily be manipulated by people who are looking to take advantage of him.
