Skeptical Rogues

Quote of the Week

Induction, analogy, hypotheses founded upon facts and rectified continually by new observations, a happy tact given by nature and strengthened by numerous comparisons of its indications with experience, such are the principal means for arriving at truth.

Question #1: False Negatives ()[edit]

Subject: Should we be worrying about false negatives for Coronavirus testing?

Message: I've been seeing claims on Facebook where people state that COVID19 testing is "30% inaccurate," is just a placebo, and that we should not even bother with it. No citations of course, but I think they are referencing this article: The Conversation: Coronavirus - How accurate are Coronavirus tests?[6] I'd love to hear a more in depth analysis of the subject!

Item #2: A new study finds that drones are more energy efficient than diesel delivery vans in urban settings.[8]
Item #3: Researchers find that drinking coffee (regular or decaffeinated), over the short term, significantly increases sensitivity to sweetness and decreases sensitivity to bitterness.[9]
