Highly clickbait title. The conclusion is that you rest meat because it keeps it juicy and lets it finish carry-over cooking. This is already the common wisdom. The only new part is a different explanation for why resting makes it more juicy.
No, the article concluded that resting meat does not influence juiciness. In the blind test the author ran, the tasters could not identify a difference in juiciness between rested and unrested meat.
I call bullshit. Resting the meat keeps the juice inside. This is objectively the case, whether or not some blind taste test agrees. (I'm not even sure why a blind test is relevant here...)
