When you're saturated it's hard to be open to disconfirming evidence.
When you're saturated and focusing on executing, any disconfirming evidence will derail you.
But disconfirming evidence builds up, and at some point your model is dangerously miscalibrated.
Being in diverging mode allows you to absorb disconfirming evidence, but not execute.
Being in converging mode allows you to execute but not absorb disconfirming evidence.
You must oscillate between converging mode and diverging mode on a regular cadence.
Note that if you're in a team, you all must be in the diverging mode or converging mode at the same time.
