Intelligence is not a trait; it is an action.
All of our pseudoscientific attempts at measuring human intelligence and categorizing human beings by their supposed intelligence are bullshit and our entire meritocracy and our eugenics and all our other elitist ideas built upon this assumption are bullshit too.
We are often led to believe that whatever a person does is what that person is. A person who does some clever things is regarded as innately clever and we assume that they have always done clever things in the past and they will continue to do clever things in the future and so they are therefore more valuable than other people.
Anyone with a conscious living brain is capable of doing clever things, capable of intelligence. Just as there are no good people or evil people, which is another absurd reification of human behavior that we have yet to fully grow out of, there are no smart people or stupid people. There are just actions, things that people do. People will do something clever one day and do something stupid the next. People will do one thousand clever things in a row and then they will do the stupidest thing imaginable and create a catastrophe.
Most of us (hopefully) can agree that it is ignorant and dehumanizing and wrong to define a human being's worth by their disabilities - why should it by any different to do the same for their abilities? Why would reducing people to what they *can* do be any more acceptable than reducing people to what they *can't* do? It would seem to me that dehumanization is dehumanization, regardless of whether it is positive or negative; the superhuman is just as dehumanized as the subhuman.
Maybe it's time to stop thinking of intelligence as a thing that people have and start thinking of it as a thing that people do, something that all people are capable of, something you cannot measure with some universal metric, something that is relational and context-dependent. Conservative propaganda film Forrest Gump famously claimed that "stupid is as stupid does" but perhaps we shouldn't be trying to evaluate human worth at all and we shouldn't base our conceptions of human intelligence on a movie that repeatedly insists that the main character is mentally disabled just because he has a funny accent and doesn't understand the rules of football.
