People confuse the word cynicism with the word skepticism. One is “you’re not gonna pay attention to anything, think everything’s screwed up, nothing’s ever gonna work out right”, that’s cynicism. But skepticism is, “you’re presented with evidence and you do your best to draw conclusions based on that”. So, as the saying goes, Bill Nye, do you believe in ghosts?
