I wish LW had a bit more of a handshake culture where we try to converge to a common phrasing to describe a topic before we actually try to discuss it. Something like

Do I understand you are saying [paraphrase]?

Sort of, but I also mean [original paraphrase with additional, necessary detail].

[ ... ]

I was going to say that [initial phrase] demonstrates [this tricky bias] but since you pointed out [necessary detail] then I guess it could have been [this other thing].

This allows the first person to demonstrate their reasoning about what they initially wanted to say, but also consider the actual problem, as well as gauge how far off their initial guess was. And then the other person doesn't feel misunderstood, so they're motivated to continue the conversation instead of just not replying.
