Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 50 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 6 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

Handmer: Taxing aviation fuel is regressive and hurts marginal travelers
“That's actually super, like, regressive because people like you and I will still be able to afford to fly. We're not super price sensitive when it comes to, you know, flying, flying United, but actually it's the people on the margin who could, you know, it mak…”
Handmer: Most people should avoid founding hardware startups
