Do serif fonts get you better grades?

Last week I saw a documentary called Helvetica, which explored the history and culture of typefaces, and the sans-serif Helvetica font in particular. It got me thinking more about the almost sub-conscious power of the fonts used in the writing all around us, and the ones I use myself. (It’s a fun and elegant documentary by the way, and not at all as boring or geeky as it might sound.)

Coincidentally, a couple of days later I came across a blog posting called The Secret Lives of Fonts, in which the author reviewed 52 papers he wrote for university courses and found that on average he got better grades on the ones where he used serif fonts than on the ones where he used sans-serif fonts. He writes:

Well, would you believe it? My essays written in Georgia did the best overall. This got me thinking as to why that might be: maybe fonts speak a lot louder than we think they do. Especially to a professor who has to wade through a collection of them; Times seems to be the norm, so it really doesn’t set off any subconcious triggers. Georgia is enough like Times to retain its academic feel, and is different enough to be something of a relief for the grader. Trebuchet seems to set off a negative trigger, maybe just based on the fact that it’s not as easy to read in print, maybe on the fact that it looks like something off a blog rather than an academic journal. Who knows.

What fonts do you use, and have you noticed patterns like these? Professors and TAs, do you have typeface preferences for the papers you need to grade? Is there something to this?

Myself, I like Verdana, but I’m mostly reading my own words on screens now. Maybe I should think again and change the font just before I print it out…
