““Branches are generated by any quantum event, right? Even before we had prisms, branches were still splitting off constantly; we just didn’t have access to any of them. If it were true that there’s always a branch where you pick up a gun and shoot someone on a whim, then we should have seen the same number of random murders every day before the prism was invented as we saw every day after. The invention of prisms wouldn’t cause more of those murders to line up in this particular branch. So if we’re seeing more people killing one another since prisms became popular, it can’t be because there’s always a branch where you pick up a gun.” “I follow your reasoning,” said Zareenah, “but then what’s causing the rise in murders?” Kevin shrugged. “It’s like a suicide fad. People hear about other people doing it, and it gives them ideas.” Nat thought about it. “That proves that the argument can’t be right, but it doesn’t explain why it’s wrong.””
