> Psycho-history is fiction. You're not going to be able to model a single human much less millions of humans and their environments.
Of course it is fiction, but to be precise, within that fiction it was also stated that it's not possible to model a single human; the whole idea was that large societies of humans behave statistically in a predictable way, exactly because then non-predictability of any individual human becomes statistically irrelevant.
