18. Lee Harvey Oswald – INFJ
Of the four presidential assassins in American history, two are arguably the most famous. Few Americans recognize the names of Charles Guiteau and Leon Czolgosz, who murdered Presidents Garfield and McKinley, respectively. But nearly all know the names of Lee Harvey Oswald and John Wilkes Booth. The latter, an actor by profession, shot Abraham Lincoln in a theater. Though he too is assigned differing MBTIs, nearly all agree that Booth was an Extravert, deeply concerned with what the world thought of him. He spent most of his time on the run after shooting the President justifying his actions to posterity, in the form of a diary. He considered himself ill-used by the world, which should have recognized him as a hero and martyr, in his own estimation. The world did not agree, even in the South, which he believed he had served.
Lee Harvey Oswald, on the other hand, is usually considered an introvert, and often receives the type of INFJ (Introvert, Intuitive, Feeling, Judging). As noted, the type is the rarest of all. Oswald had several psychiatric evaluations in his lifetime, including as a teen. They all noted his isolation, withdrawal from relationships, and lack of friendships. He also denied killing John Kennedy, declaring he was a patsy. Unlike the extravert Booth, Oswald did not desire a judgment from the world. Instead, he wanted to be invisible. By the way, there are those who argue Oswald’s victim shared the personality type of his assassin. While most describe Kennedy as an Extravert, others argue he was in truth an Introvert, completely uncomfortable with the extraverted aspects of politicking. Once again, the image is in the eye of the beholder.
