I am wondering, is there any research or just reasoning over whether a human perceives text easier if it is in questions and answers format or if it is structured with headings and sub-headings.
Questions and answers is close to the natural dialogue communication between two people, which is what we have been accustomed to for ages. One sided communication - text-to-reader is a very recent novelty, evolutionary speaking.
At the same time, I have this obscure gut feeling, that Q&A format, even if combined with headings, does not look "authoritative" enough. I cannot explain why, this is just the way I am feeling it.
The specific occasion for coming up with this whole question is that I am writing a job ad. And I have the feeling that if I use Q&A format, it won't look serious, won't be memorable, or something like that.
