I now see very clearly where you are coming from. It makes sense that determinism as such cannot be proved. Yes, that much is clear. And perhaps with regard to this, it would be better for me to select a different word to try to get at some of the things I would like to say, in lieu of determinism — because apparently “determinism” is too philosophically precise. Maybe “destinism” might be a looser abstraction for what I want to say? Or “originism”? It would have to imply more of a fuzzy range of possibilities, whilst still retaining some sense of high likelihood based on the origin the matter, for instance culture. One might say that there is a strong cultural originism in people following the rules of the traffic lights in advanced industrial countries, but there is also a high originism in people disobeying red lights in parts of south africa, where they fear carjacking. This too is cultural, and thus rather predictable up to a point.
