Not sure I fully agree - sometimes maybe, but I think in the majority of cases it's used when people feel they dont need to explain exactly what they mean because it should already be obvious to most people.
Example. "Always look when you cross the road" is a snippet common sense, with lack of heeding to that sense resulting in you potentially being hit by a car. Even a 4 year old wouldnt need the latter explanation, but most people could articulate that if they needed to. Its just a way of speeding up communication
I was quite old when I realized that Common sense is literally “common experiences”.
A colleague and I were lamenting a laughably bad outage that we thought showed a total lack of common sense resulting in an obvious issue. Then we both realized that the team had never had such an experience whereas the two of us had. Every member of that team now has that particular “common sense”.
Likewise, “don’t run in front of cars”. As a kid, a mate broke his leg running onto the street and getting hit. I think near misses happen a lot when we’re kids.
But far fewer has an “common sense” about prompt engineering because there’s just much less experience.
