Sure there is a difference. The comment I was replying to was talking about making text accessible to outsiders though. Even just talking about plain English is a bit problematic though - the problem is that a whole bunch of technical disciplines are jargon heavy and not easily amenable to straightforward plain English. If you’re talking about things like general flowery prose, it essentially doesn’t exist in the hard sciences - at least that I’ve seen.

Maybe the humanities are different, but I sometimes wonder if the humanities are under more scrutiny because they deal with topics laypeople reckon they have a good intuitive grasp on. I actually had an interesting time at a party recently watching a sociology grad student working on the Scottish criminal justice system politely nod as a young English woman lectured her on the topic purely based on whatever half digested stereotypes she’d picked up in her 30-odd years.
