It's so frustrating to me that we keep regressing our political conversations with assertions of this nature, that intelligence is a social construction, when in doing so we are literally turning a blind eye to what is arguably one of the greatest injustices our society faces. Intelligence is not a social construction, and it's not distributed equitably, and that isn't fair. It's the single greatest psychological signifier for material success. I'd much rather accept reality as it is, and spend resources attempting to ameliorate objective injustices, rather than making assertions that intelligence is a social construction because it gives some opening for a utopian alternative that can simply dispense with our "oppressive conceptions of competence."
Doesn’t mean it’s not “real”. But I also would not say it’s “abstract” in any meaningful sense. It’s certainly not derived from first principles, nor do we have any kind of theoretical model of intelligence that’s good enough to construct measures around.
This is exactly what social construction is: reifying a set of observations into an abstract notion. Intelligence is a social construction.
