Font choice can affect more than just the bottom line. A 2010 Princeton university study found readers consistently retained more information from material displayed in so-called disfluent or ugly fonts (Monotype Corsiva, Haettenschweiler) than in simple, more readable fonts (Helvetica, Arial).
Plus, New York Times writer Errol Morris and Cornell university psychologist David Dunning suggest texts in some fonts (the informal, oft-mocked Comic Sans, for example) tend to be viewed as not worth taking seriously, while other, weightier typefaces – particularly Baskerville – seem to inspire a belief that they are true. Which is, one imagines, what a government would like.
