Rather than non-judgmentally listening to what people have to say, the mind jumps to some conclusion or as you said wants to complete a sentence out of habit or exposure some stimulus. Sort of monkey mind.
I know that my ideas and my words aren't the same thing because I'm always at least slightly unhappy with how I'm expressing myself, which tells me there is a separation and dissonance between the two.
It’s not so bad. I think there are times when we devote a lot of thought to craft communications that share interesting things in novel ways. But most of the time we’re on autopilot and lower layers of cognition fill in the next most likely word, resulting in low effort comments scolding others for low effort comments, with no recognition of the humor in that.
You have comments in your history that would count as low value. Why didn't you take them elsewhere?
Quite frankly this view ignores decades of cognitive science that clearly demonstrates that the brain is not just predicting next tokens.
Kidding aside, I think this a version of differences in visual imagery between individuals.
