Hide the Chocolates

When the conveyor belt overwhelms Lucy and Ethel, they hide unwrapped chocolates in their mouths and clothes. Seeing no missed pieces, the supervisor concludes that they are highly capable and speeds the line up again.

Superficial oversight sees a perfect output record while concealed failures accumulate, so the evaluator rewards apparent success by increasing the task difficulty.

The workers consciously hide errors under impossible conditions; the analogy is to evaluation and oversight, not an autonomous AI objective.
