Sometimes one side or the other is on the side of truth, but even then, the other side benefits from the uncertainty. The further they are from that position the greater the relative benefit. If there's even the slightest hint of gray they benefit even more.
Representing the middle is a pure loss. Both sides benefit from the clarity of their positions and the ability to commit. Usually both sides will assume your are on one or the other, and both benefit from that. One side gets a slight advantage from your numbers. The other benefits more from painting you as the enemy who will stop and nothing to destroy you and must be stopped at all costs.
Reality, it turns out, is badly overrated.
