This works fine as long as the participants understand. If we attend with a preconceived notion and stubborn, then, no conclusion can be drawn.
This logic may work in official deliberations. But, mostly it will not on public road or at home where emotions play major role compared to technical strengths. We should be careful in such places and should not take to our head that we lost our position. If we win the person(s) even by losing the argument(s), it is a batter option and gives us peace of mind and happiness and also safety (on public roads).
