You shouldn't trust any large _institution_ to prevent "obvious lies" from spreading. Institutions are just collections of people, and there's barely a single one out there that's managed to completdly avoid the fact that people are, generally speaking, dishonest and dumb.
You'd trust The Economist (or the CBO) to be the arbiter of what other people are allowed to say? That's what my comment says, not "trust any institution to avoid telling obvious lies" (that being said, I've read some pretty dishonest stuff in the Economist, despite generally being a fan).

They already do that with their own employees. They censor and control what statements they print to control for accuracy. Journalism concerns in part determining what true statements we should print. I think the Economist and CBO do a good job of separating the facts from the fiction. I would trust them to fact-check statements. I would not trust CNN or Facebook or the Democrats to fact-check statements.
