White hat as seen in 973: MTV Generation
|First appearance||260: The Glass Necklace|
White Hat is a stick figure character in xkcd. He is distinguished by his eponymous white hat which appears to be in the shape and style of a boater. His appearance is identical to that of Black Hat other than the color of their respective hats. Unlike Black Hat, however, doesn't necessarily represent the same character in each appearance.
Interestingly, the two characters have been depicted together only in 1110: Click and Drag, 1000: 1000 Comics, 1708: Dehydration, and 1756: I'm With Her still without a real connection between them, although they actually speak in the same setting in the latter, the other two being large drawings comics where they do not meet. The same goes for the other white hat guy, Beret Guy. See more on how little these three interact in xkcd in the explanation for Characters with Hats.
In early comics, White Hat appeared mostly as a rare secondary character. But starting with comic 915: Connoisseur, White Hat began appearing more often and developed more of a personality, often playing the role of a philosophically misguided person. In this way, he's a bit of a straw man, making logical fallacies to help advance Randall's point (see also 973: MTV Generation, 1215: Insight, 1255: Columbus and 1277: Ayn Random). Other times, he is simply an alternative to Cueball or one of the other main characters.
In 603: Idiocracy a character with a white hat appears, but it is a rounded safari hat very unlike White Hat's usual boater. He also has a very different mindset so there is no reason to believe that he is White Hat at all, and the comic has been removed from the list of those with White Hat. Main reason for this, is that White Hat already appeared in his normal hat three times before that comic, and Safari Hat guy has never been shown again, except in 1000: 1000 Comics.
