Suppose that for twenty-eight years in a row, Consumer Reports rates itself as the #1 consumer ratings magazine. A picky reader might complain to the editors:

You are evenhanded and rigorous when rating toasters and cars. But you obviously have an ad hoc exception to your standards for consumer magazines. You always rate yourself #1! Please apply your rigorous standards across the board in the future.
