OK, yes, we do take a position on that point.

Happy to see you reading on this. Most of the literature does deal with
some stable end of a conversation, but one paper does not. See:
"Disagreement is unpredictable"

Practice rational reasoning involves lots of error-prone reasoning
disciplined by meta-processes that look for and correct for systematic
biases. http://hanson.gmu.edu/disagree.html talks more about this.
Psychologists have studied this a lot. See "Metacognition" and the
"flexible correction model". If you find that your disagreement is
predictable, I think you should think of that as having uncovered a
systematic bias to correct for. In general, you just more your beliefs
in the opposite direction from the bias you perceive.
