Not necessarily, you can post citations for what underlying lines of evidence support that the prediction will be accurate. That’s what you do when trying to prove a hypothesis scientifically.

That would be a great comparison if it were even tenuously related to today’s media environment, Trump’s charisma to his base, and hyper-polarization.
