Not all ex-post theories are BS. For example, I slam my hand in the drawer and theorize, "Slamming hands in drawers hurts; one should not do it." That theory is pretty solid. It doesn't cover all the edge cases, but following it is better than not following it.
There are lots of startup theories that are equally solid, despite being ex-post. I know a startup that didn't pay payroll tax for a couple years, and it ended badly. The resulting advice is pretty obvious.
There are theories about how to hire, how to find customers, how to negotiate deals. These theories might not apply in every single case, but you should definitely start by knowing what worked in the past.
This post picks a couple of unsupported startup theories, but it's sort of like criticizing physics for the 1% of reality it can't explain and ignoring the 99% it can.
