Had a few courses at Uni with Comic Sans in the slides. So apparently Comic Sand is a very legible font. Maybe that’s the reason so many people choose it or they just like it.
The claims struck me as a bit unlikely, but helped explain its widespread adoption in higher education beyond differences in taste. A quick searching suggests that there is little evidence for the claims made about it, but I can see why some would still use it.
Still, at least it’s not Papyrus.
