I wonder whether it's worth tagging questions as confirmed (the evidence supports the notable claim doubted), rebutted (the evidence supports the negation of the claim), partially-confirmed (the evidence supports part of the claim), partially-rebutted (the evidence supports part of the negation of the claim), or none of the above (insufficient evidence). (Or both partially-confirmed and partially-rebutted.)
These would serve two purposes: First, they'd serve as a "tl;dr" synopsis of the answers for someone reading the question, that he might know what to expect from the answers. Second (and IMO more usefully), they'd allow statistics to be drawn (e.g., what percentage of claims about economics were rebutted?).
