> Just because you can't prove it doesn't mean it's not true. It does mean you can't show it to be true, which means it's entirely rational not to accept it as true until that kind of evidence is presented. What is really going on here is that you prefer serifs, without this being a global truth for everyone. That preference would continue to be a thing even if it were found that sans-serif were 1% more readable or something. Some people will still prefer serifs and be upset if they don't have them and in cases like ebook readers, that may be important to consider. It isn't necessary to stretch to claims that serif fonts are objectively better in some way, in order to have a reason to use them or make them available.
