Reading the NYTimes op-ed page these days I’m left wondering about the theoretical possibility of a knife so dull it actually unsharpens the rest of the cutlery in the drawer.
@andrew negative sharpness?

@josh Yep! A paring knife so blunted and edgeless it robs all the steak knives of whatever slight hone they had when they went in there.

In the context of the op-eds, maybe it'd be a choice in order to facilitate the "both sides" nonsense. If you're hell bent on presenting a given position as being balanced, you'd have to offset the natural tendency for the correct-thinking side to be more on the ball. i.e. “Love it, but make it dumber. Your opposing viewpoint is typing with his nose.”
