In my case, no. There is no conscious 'refinement' of speech options like a Disco Elysium scene or something like that. I mostly just say what I think. There is definitely some impulse control type function to keep me from saying, for example, offensive things, but it's not in the form of myself telling myself 'dont say this thing'. It's usually in the form of an intrusive memory of a facial expression or negative emotion that I associate with that branch of conversation, if that makes sense? Same end, I think, just without a verbal component.

I have moderate inattentive type ADHD that manifests as me being hyper focused on specific sometimes minor things and failing to effectively plan larger picture things and often results in poor executive function outcomes. Maybe that's part of it.
