Ask Lemmy

The core concept of the books was, that Hari could predict the future of societies in really broad strokes. Essentially how masses behave in certain situations. In order to actually make the gamble, he forced a situation where he put a group of people that could only behave in a certain way because they were lacking resources.

But, in all of the books it's quite clear that Hari couldn't make predictions for single people within a group, because there're too many variables (Asimov even created an example where Hari deliberately predicted the choices of a single person that exists in the present, and why that doesn't work for other purposes).

In the books, Hari cannot make any decisions for other people, because the solution can only come from those people (though because he setup the foundation colony like he did, the outcome was always predestined).

In the show, they don't care about the core concept. In the first season they show how psycho history is supposed to work, and partially adhere to it, but soon ignore all the limitations that it should have. It's like Hari plays those 1000 years on a musical instrument, manipulating people and situations. He tell's people the solution to the problem. He (because he's an AI) constantly interferes. That's not the idea of the core story.

Imagine it like this, in the books, a "creator" setup the world in a way where people can still make individual decisions, but only in a way that leads to a predestined outcome. Personal choices may lead to a different way to the outcome (see the mule), but in the end, it'll always come to the intended solution.

The show just has an omnipotent god that is reborn and moves people like chess pieces, constantly adapting to changing situations.
