To paraphrase the author's point -- the doctor could have a policy to intervene only if the screening produces _flagrantly_ worrying results, and continue to not intervene in cases where the results are merely mildly worrying. Technically, this might lead to strictly better outcomes at the ensemble level. But any patient likely 1. doesn't care about ensemble performance 2. will get stressed out at the mildest indication of concern 3. induce a concave payoff for a trigger-shy doctor (no credit for correctly not intervening, and massive discredit for incorrectly not intervening).
