This is by no means a personal attack but this is approximately the thought pattern the parent comment is arguing against.

Absence of evidence does not prevent you from making decisions or otherwise coming to conclusions. The fact is, you can make decisions with no evidence at all. Your outcome may be no better than chance but also likely no worse.

Not making a decision can be worse than chance, especially in time critical or low information environments and if you always “wait for the evidence” you will end up being worse than a magic 8-ball at the most crucial moments.

There is no "not making a decision". It's not that you can make decisions without evidence, you must make a decision even without evidence. Not wearing a mask is as much as a decision as wearing one.
