The powerful often receive agreement when what they actually need is correction.

What arrives is agreement, what is needed is correction, and the gap widens the higher someone sits. People agree for many reasons that have nothing to do with being convinced, and the person receiving all that agreement is the last to know it is not real. Isolation of this kind feels like support.

Ask directly for the strongest case against your plan, and reward whoever gives it. Publicly, if you can. That is what makes it happen a second time.
