    An overly complex model invites #overfitting

    Breakthroughs in domains occur where an accumulation of many complex rules can be discarded for a small set of simpler ones. Physics: Newton on gravity, motion, and optics. Chemistry: Mendeleev on chemical elements (valance electrons and atomic masses), Biology: Darwin and evolution (and genetics and DNA). Geology: Wegener and plate tectonics. Information; Shannon. Computer science: Turing & Church.

    The social sciences have been approached repeatedly by their core truth but to date have rejected it.
