I believe Nassim Taleb wrote about this in relation to 'virtue signaling' - not swearing being a sign that people are trying to 'signal' professionalism in order to keep their jobs, and therefore are more likely to have less actual professional skills (which if good enough would secure their jobs regardless of profanity) and vice-versa. Same for hoodies over ties, etc. Although all this probably gets flipped now that we have people writing papers like this - context is everything.
