All you need do is listen to very smart people and sift out the ideas that are unworthy or implausible, and I wouldn't pretend for a moment that I hadn't made lots of mistakes and there are companies, perhaps, that we had been investors in.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
