Do sunspots affect human creativity? The brain is, after all, a finely tuned, highly complex electro-chemical meatball, and sunspots are able to disrupt electrical systems of far simpler, less finely tuned nature.
It turns out I’m not the first person to ponder such a connection (which is a good thing, because I'm also too lazy to try and verify it). A professor named Suitbert Ertel exhaustively examined the historical record, and concluded bursts of cultural creativity, across the globe and throughout history, occurred 10 to 15 years after periods of low solar activity. Ertel has a lot of unusual ideas, but Hans Eysenck, for one, was impressed by Ertel‘s theory and evidence, concluding, "However difficult to explain, the facts do not admit of any doubt; there is a close coincidence in solar activity and human behaviour."
Presently sunspot activity is extremely low. If Ertel is correct, contrary to what we see all around us, our culture isn’t dead; in reality we are on the verge of a great artistic flourishing.
