@Frances_Larina @charliejane it's effectively used as a means of supporting the delusion that we live in a meritocracy, as a means of justifying the exclusion of other perspectives, & as a means of justifying the denial of autonomy.
As it's used, the concept does not exist. There is no numerical value one can assign to rank intelligence & correlate it to their value, impact, & contribution to society (one's connections & net worth will always have a higher correlation). As such, the purpose of measuring people's problem-solving abilities must be different than the purported meaning of intelligence/IQ (which people seem to use interchangeably). It seems to just be a lie embedded into our language to reinforce support for hierarchy & imperialism.
