This narrative (though the believers deny that there is one) is based on the premise that cataloging and neutralizing biases will eventually leave behind a rationally empiricist core of perfectible humanity, free of deluded narratives. One educational magic bullet per major bias. The associated sociological grand narrative is about separating the world of the Chosen Ones from the world of the Deluded Masses, and using some sort of Libertarian Paternalism as the basis for the former to benevolently govern the latter without their being aware of it.
