"Output exactly one label: True, Mostly True, Misleading, or False. No explanations, no qualifiers."

That's exactly the stupidity of the public discourse these days. People feel compelled to take a clear position although there is much more subtlety in many issues. It's not ok to say "I don't know", "it depends" or "as far I know". And then people feel they need to defend this position no matter what new information comes up.
