I find the phrase “common sense” to be an oversimplification. It seems to roughly translate into “reliably demonstrating good judgment.” In order to do that, these requirements seem to be necessary: calling oneself out on BS, so that personal biases don’t get in the way of function; being proactive, so that opportunity doesn’t fade away; and constantly, CONSTANTLY saying humble, so that one can act without the hindrance of thinking they know what they don’t, and so that they can adjust their strategy according to new evidence.
Not trying to sound pessimistic, but these qualities don’t seem very common at all.

It so appears, and I have been saying this forever now, that common sense is not really very common. And the more I dig into it, the more it appears to be rare! Hopefully, your post might be able to jostle people to stop and ponder on this! Good work.

Indeed! Justifying a position as “common sense” is actually a little bit elitist, I think. It demonstrates a refusal to see that someone else’s experiences and upbringing could have caused them to see differently.
