It's called the Pareto principle: 80% of the effect of anything is created by 20% of the causes: companies make 80% of their profit from 20% of their customers, 20% of your training is sufficient to do 80% of your job.
In other words, it takes little effort to do a job sufficiently well, it takes a monumental effort to do it perfectly.

No no, I’m aware of the Pareto principle! What I wasn’t sure about is how that applies in this case, given that we’re discussing skepticism as it might apply to the larger superstructure of the hundred-and-one things, the thousand-and-one things we implicitly believe in, unconsciously take for granted, despite not personally having verified them.
And you're saying, "it takes little effort to do a job sufficiently well, it takes a monumental effort to do it perfectly". Concentrate on the low-hanging fruit, in other words.
But doesn't that already, at the outset, makes presumptions about what is important? That sounds circular-ish to me : because while it could be that in most instances this presumption (80/20 in the sense that you mean it here) would turn out to be valid, it could also be that the presumption does not, in fact, hold in many cases that we do take for granted. The point is, we wouldn’t know, starting out, whether this 80/20 thing does hold here, would we? Concentrating on “low-hanging fruit”, while no doubt a practical enough approach, is a bit like hunting for your lost keys, not knowing where you’ve lost them, under the streetlight because that is the portion of the road that happens to be clearly visible. Practical enough, in a limited way, and for all you know it may work, at times, if you’re lucky : but not necessarily ‘right’. And certainly not ‘enough’, at least if you’re at all serious about finding your keys.
You aren't talking about skepticism, you are talking about scientific study. Some mathematical arguments might be really hard to prove or disprove, but those are the rare exception.
If you can't explain your reasoning to others, it is usually not because they can't understand it.
I think I may not have been able to make my meaning clear to you.
You’d said that if someone manages to stump you with clever reasoning, it is probably worth dissecting the argument anyway, even when that argument is wrong. I was wondering how that might pan out, given that there are so very many things all around us, that we implicitly take for granted without personally validating each and every one of them. After all, we leave all of these things untested and personally unvalidated largely because it is simply not practicable to go around doubting and testing everything! (And also, of course, because most don’t think to doubt these things at all. But the point is, even when one might think to doubt them, even then in practice this becomes a fool’s errand.)
And so, what we’re left with is what we started out with : lots of things that we personally haven’t verified, but which nevertheless we accept. Which may be fine, perhaps there’s nothing under the rock at all -- but we wouldn’t know, either way, would we, since we haven’t look?
That was the issue. I think this is an issue squarely about (personal) skepticism, not scientific study. And this does not necessarily relate, except only obliquely, to how difficult it is to prove or disprove some individual argument(s) or position(s).
