Dictionary.com discusses how fonts like Comicbook Sans helps us learn better:
Another study involved 222 high school students who, over the course of several weeks, received assessment tests in both hard-to-read fonts and the traditional easy-to-read fonts. The students who learned with the ‘funky fonts’ scored higher.
While this is on reading and learning, I wonder what the impact is to writing. It’s an interesting thought. I might consider switching to a funky font when I print a first draft.
