Content presented in a serif font appears to the reader to be more credible. This 'study' was a survey that appeared on an online version of a newspaper. The tested content was wedged inside an article that always used a serif font, on a website that always uses a serif font, in a part of the writing industry that nearly always uses a serif font. I'm not that confident that the findings can be generalized to technical readers reading technical blogs, where the standard is sans serif. How do we know that following industry standards for the type of content isn't what made the serif fonts look more credible?
