Yes it is more of a hypothesis, as it's completely unproven at the moment.
So my next additions:
'Garamond' - prefers the more traditional, but not so overtly as to use book antiqua. Cares about the way their work looks on paper and therefore thinks constantly about the legacy that their work might have upon humanity. Self-important but not overtly so.
'Comic Sans' - brash posing type (as someone has already explained)
'Any ancient of biblical Greek font' - Probably a theologian or a classicist, enjoys the feeling of tweed against skin. A bit of an anachronism (I only add this one is as I have, and regularly use, a Biblical Greek font)
'Pseudo-handwritten type face' - I possibly put smly faces above the letter 'i' as i think that it looks nice and makes people feel better. I believe that this is makes me connect with my audience, but in fact most think that I'm a bit of a simpleton. A pushover.
nb- I've noticed a trend among books I read to explain the history of the typeface that it uses. A weird last page to any book, in my opinion.
