> The general public doesn’t perceive serif typefaces as professional and authoritative, a priori, before prioritizing their use in formal settings. Instead, people first observe that government, academia, and corporate workplaces disproportionately use serif faces — or are trained to use them — and only then infer that serifs must mean professionalism and authority.
A difficult to stomach claim followed up with evidence that I think supports the opposite than the author intended: the font being in used in The Times of London, which is indeed authoritative and professional despite it being written on cheap paper.
On another note, I would throw up if I had to read legal documents all day in a sans-serif font.
