Quo Pretio

Quo Pretio (At What Cost) is a logical fallacy where you attempt to derail or invalidate an argument by obsessively focusing on irrelevant, minor, or speculative costs, consequences, or details instead of engaging with its core merit. The classic move is to respond to any proposal or point with a skeptical "Yes, but at what price?" and then list a bunch of tangential downsides—like administrative hassles, potential for minor misuse, or aesthetic complaints—as if they are fatal flaws. It’s a cheap debater’s trick that avoids addressing whether the main idea is good or true by pretending to be the sober adult in the room worrying about the forgotten fine print.

*Example: "When I suggested upgrading the office coffee machine, my boss hit me with Quo Pretio: 'But at what price? Better coffee means more caffeine, which means more bathroom breaks, higher utility costs, and what about the syrup spill potential on the new carpet? The fiscal and sanitary ripple effects are unknowable!' He didn't argue against better coffee; he just drowned the idea in a flood of irrelevant cost-anxiety."
