Yes and no, stupid people are typically aware they they have less intelligence but they devalue the increased intelligence as trivial in the grand scheme of things. Much like you don’t think you’re stupid for not knowing the latest development’s in Pokemon.
Stupidity and ignorance can also be defined as different things but I won’t get into that.
Patriotism and religion are intimately linked on this front because they allow a person to think that so long as they are productive members of society or so long as they are devout all other knowledge is irrelevant.
The tricky thing is, they are right in a number of ways. For one knowledge in and of itself is of no intrinsic value. Its worth from a human perspective stems directly from what is done with it. Further, intelligence is limited per brain. Since we know we can’t possibly know everything we grant that no matter how intelligent a person is they must by definition as individuals exclude wide swaths of data.
Further still intelligence may not be adaptive. It may be a comedy but look at Idiocracy, it’s very reasonable to assume that intelligence in certain social systems can be as genetically damning in the long run as sterility.
There is even one species of sea life that eats its own brain at one point of it’s development. (Sea squirt.)
Stupidity may very well be a social construct just as insanity. Ultimately there’s no way of knowing its value or harm to the species, and to the individual, we typically just accept what we are given.
I prefer to think of life as being a quest to make more life for the purposes of increasing pleasure all around. If that’s the case and ignorance truly is bliss then maybe stupidity is not only adaptive, as in the case of a solider ant having no idea it’s about to die and doing its job anyway, but it may be ethical to foster it, if as in my example intelligence proves to serve only the interests of death and suffering.
I personally think intelligence will ultimately give birth to true happiness and longevity but if you take the current form of humanity as a static thing to be shaped only by the whim of mate selection and evolution than perhaps being smart is pretty stupid.
