The social-science depiction of a human person is objectified, rendered stable, predictable, finite, and quantifiable. It is also a stereotype of a person. We have these quantum computers between our ears, yet in human behavior as in quantum physics, the spontaneity and indeterminacy of individual quantum phenomena cancel out in the aggregate. This is why the macroscopic material world is relatively stable, despite the wildness at the sub-atomic scale. This is also human populations are more predictable than human individuals.
-- Yet the theorizing activity of the social scientists themselves violates their decapitated portraits of human persons, in the creativity and freedom they employ in the process.
