I agree. I couldn’t help wondering while reading the article if older users are faster with serifed fonts and younger users are faster with sans-serif fonts, however they never touched on it.
> 3 fonts were actually better for older users than for younger users: Garamond, Montserrat, and Poynter Gothic. The remaining 13 fonts were better for younger users than for older users, which is to be expected, given that younger users generally performed better in the study.
They kinda did touch on it. From what I can see, letter sizing and kerning looks to make more of a difference.
