Illustrative numbers in a simplified version of the paper's model. Not a test of any real AI system. The human knows whether the robot's plan is good (+10) or bad (−10); the robot only has a belief.
Value of waiting minus the better of acting now or switching off. The paper calls this the robot's incentive to defer.
The paper adds that this uncertainty isn't free. An agent that is overconfident about its objective will be difficult to correct, and one that is under-confident will be ineffective.
