Very well said. Personally, I tend to think of it as hindsight before the fact. When people look back at major events like WWI, WWII, the fall of Berlin Wall, and eventually the Soviet Union, most of the signs were there. There were subtle "vibrations" appearing in the system and major rattling in the system. It's only after the fact that everyone says "oh yes, given A, B, and C, it was obvious." I think about Seldon's psychohistory less as predicting the future and more of simply identifying A, B, and C before the "obvious" event occurs. Throw in the Second Foundation's tweaking and it seems plausible.
