It’s takes real skill to take a concept that has been developed over years of highly technical debate and scholarship and make it understandable with normal language, even if the underlying concepts are actually super simple.
I think a reason for this is that in highly technical or complex fields, it’s counterintuitively easier to speak in full jargon, since that’s how ideas are developed and how people in the field are convinced of their validity. Using language for the “public” can often mean you lose some of the more subtle meanings, though you’re right that at the end of the day the explanations that we end up with are usually easy for most people to understand.
So I think it’s actually pretty natural to start with jargon and then refine the ideas by translating them into normal speak.
Example?
People using specific terms that people outside of the field do not know. We need those terms for efficient communication, but when talking to someone outside of that field many still use those and expect everyone to understand them.
I don’t think it’s a deliberate thing to use technical jargon you’re used to. It’s just that you’re used to it so your brain thinks everyone does too.
It’s not a matter of ill intent but just a lack of pedagogy.
