The soft sciences collectively suffered a mental break after physics described reality in increasing detail for a century. They remade themselves in the image of physics, in a cargo-cult hope it would bring them the same validation.

Ironically, the only thing that even comes close is IQ. Read The Bell Curve and be amazed at the predictive strength of IQ and its resilience against manipulation (blacks raised by adoptive parents from birth in upper-middle class, White environments, completely separated from their race, do not have White IQs).

Naturally, the soft-science equivalent of uniting electricity and magnetism, in terms of impact on the field, is strictly verboten.
