sbarlster makes a good point. Plenty of world-changing inventions came out of science fiction, for example, and I know that my attitude in life has changed for the better based on inspiration from such sources.

Evolution wired our brains for storytelling at a deep level. I would encourage you to take that desire for more factual fiction and turn it into some actual drafts. Having done the same in NaNoWriMo several times now, I highly recommend the learning experience.
