L'idea di fondo è che la classifica è quantitativa, ma le quantità sono basate su valutazioni arbitrarie. E quindi...
Money quote: "A closer analogy would be college rankings. When US News and World Report declares Rice University has edged out Washington University, its conclusion is based on an internal system for weighing different statistics about the school. And that system reflects the value judgments of its creators — whether they care more about research or student experience, alumni donations or selectivity. It's an art, but it offers the illusion of science."
