´intelligence´, and how it exists in our society, is still an institution within the ruling class ideology. therefore aslong as it is understood withing the ruling class ideology and often qualified by the standards excepted and created within class society.
this fits into the liberal notion of science being outside of ideology and political reality. furthermore used by liberals as they nievely atempt to palce their beliefs as neutral and scientific.
look at the adoption of science, in this form, reductionist and limited. as the dominant form of understanding within capitalist society. we know that religion was used as an institution for ruling class control during pre-´enlightenment´ class society. is it really so fucking difficult to see that the same applies here.
