Such arrogance. "I am right, and if you disagree then you must be uninformed!" Disgusting to read.
This isn't aviation we are talking about pal. It's politics. Perception determines how people vote. Votes determine who wins. That is reality.
My friend, I take a back seat to no one in arrogance. Might as well be my middle name, based on your perception of me. But you see, even if you and Random and all your other book club (or anti-book club, as the case may be) buddies all get together and, based on your shared perception, decide that my middle name must be Arrogant, there's still a document that says otherwise. That would be reality.
At this point you're probably trolling me, but I'll take one more shot at this...
Let's say mental acuity exists on a scale of 1-100, with 100 being brilliantly sharp and 1 being a vegetable. Maybe Senator Biden was somewhere around 90, VP Biden started to slip into the 80s, and now elderly President Biden is somewhere in the 70s. The important thing is, other than picking up clues/signals from the few public appearances he makes, neither you nor I nor 99.9% of Americans have a dependable, rigorous way of knowing whereabouts he falls on that scale.
On the other hand, it was a clear strategy of the Trump 2020 campaign to convince voters that Pres Biden's mental acuity is, say, in the 20s on our scale. They also don't have any reliable information to determine this--but it is useful for the (continuing) Trump campaign and the wider Republican party (are they really different entities at this point?) for voters to believe that Pres Biden's mental acuity is in the 20s and that he is therefore unfit to be president. In the absence of reliable evidence of where Pres Biden's mental acuity actually is on our scale (i.e. "reality"), Trump, other Republican politicians, and right-wing media (Fox News, OAN, all the talk radio, etc) relentlessly repeat the narrative that Biden is in the 20s and falling. This is not an accident--this is a strategy. This is the "Big Lie" strategy--repeat something often enough and people will eventually believe that it is at least partially true. It is reinforced by repeatedly and disproportionally discussing and replaying recordings of his gaffes/slips/falls. And it works. That's why you consistently can see polls where people both very much approve of what Biden has done in this term, but think he shouldn't have a second term.
So again, the results those polls asking yahoos on the street about Biden's mental acuity are a testament to the effectiveness of this strategy, but are not necessarily connected to his actual acuity. I thought we were discussing his mental acuity, not the effectiveness of Trump's latest campaign efforts.
One last disclaimer: A stopped clock is right twice a day. It's absolutely possible that the professional liars are right and that Biden is indeed senile. As you pointed out, I can't really diagnose that. Maybe someone else is pulling the strings, right? It's possible, sure... So there, even in my arrogance, I'll acknowledge that this overwhelming narrative completely unsupported by fact may be correct.
