The description of molecular feedback loops and protein oscillators appears to help explain circadian rhythms yet are still a type of black box on a par with astrology in terms of describing a "mechanism" for all the magical connections. There are potential exogenous oscillator models that looks like machines, for example, the planets. Orthodoxy seems to require looking mainly to the "nurture" environment of inner workings and the past, where there is an appearance that we can consciously influence what is expressed even if there is a lack of evidence for it. It is orthodoxy to think in terms of "owning" our genes and molecules. The unorthodox among us may look more towards the external environment and the future. To the orthodox, it may seem that we can never have conscious influence over what we experience that comes from "nature" outside.
To me, it is surprising that Dr Michael Hastings recognizes astrology as a black box! It suggests that he thinks the functionality of astrology can be researched. Much human learning is a black box and only later, when we develop hypotheses and theories, do we begin to understand the principles and mechanisms that drive the boxes. Natural selection is a black box. Machine learning is a black box that is experiencing accelerating growth. We are at the point now where, because of machine learning and AI, we will understand less about important underlying functions, processes, development patterns and decisions that affect our daily lives.
