I'm sorry, but yes it is.
First off, those are not common-sense issues. They're complex, and just because they make sense to the high IQ crowd on HN doesn't meant that they have any reflection on common sense. Just because anti-vaxxers say that vaccines are bad because "common sense" doesn't mean that it has anything to do with other than them being morons.
Common sense is that masks do something and aren't harmful to use. Common sense was right. Just because common sense and intuition are sometimes wrong doesn't mean that they're always wrong, which would be a fallacy. It doesn't even take common sense; an average joe can use basic cost-benefit analysis to decide whether to use a mask, if they are wondering whether a mask is a good idea. Trusting people(often pundits) with ulterior motives over a month after the fact would have turned out to be less advantageous.
This idea that we can't ever use our intuition because it's often wrong is dangerous. If we can't make any decision with intuition, including one as harmless as wearing a piece of paper over our faces, then we're slaves of the mind.
