I mean, a jack in the box always pops out at the same point in the song right? And yet it's still surprising. But you're not pressing a button to make it activate, it happens at a point abstracted away from your direct attention. It's always worse beforehand if you slow down and try to predict when it'll happen, so you just keep going without regard for the exact moment it pops. When it pops, if you react, that reaction follows the pop instead of preceding it.
