Part of me wants to say "duh", but studies that show obvious results are still useful. I had a similar thought when I saw the paper last week that showed masks that don't cover the nose are less effective than those that do. On the one hand, why did we need a study to show this. On the other hand, now we have a study confirming it.

These obvious studies aren't just for the yes/no answer. It also provides other data. Like, if I actively wanted to evade facial recognition then I now know that a black mask is better than a blue mask.
