There's a curious new rhetorical strategy I'm encountering more and more often in online spaces wherein ignorance about a claim is taken to refute it. It goes a bit like the script below. It's the death-of-expertise script, but with an additional twist.

Has anyone written about this?

@ct_bergstrom What if approach A doesn't have problem B or you are being dishonest and your A B claim is only true under very specific circumstances that you haven't listed?
Or the A B claim is true but not intuitive and you haven't offered any information to break the non-intuitiveness?
