Perverse incentives

• The expectation of being rewarded or punished in the afterlife is supposed to be a reason to be good in this life. But rewards and punishments are not good reasons to be good. Focusing on personal repayment distracts from the real reasons to be good, which leads to selfishness and moral apathy. Especially in this case, where no one can even confirm that the rewards and punishments are actually being carried out.
• If you do reward or punish people, they should be able to learn from the experience and know how to behave going forward. That doesn’t work if the reward or punishment never ends.
• Expecting to be infinitely rewarded or punished depending on what you believe is arguably the worst possible obstacle to true belief.
• Expecting to be infinitely rewarded or punished depending on what you do, combined with the belief you’ll be sent to hell for doubting its existence or doubting the authority of whoever’s telling you what you have to do to avoid being sent there, can make people do anything their religious authorities say, no matter how evil it might actually be.
• A lot of religious people say it’s very important to God that we have free will. And they say it’s particularly important for us to be able to freely choose whether to accept him. So what’s up with all the threats and coercion? It’s hardly a free choice if you’re threatening to torture people forever if they don’t make the choice you want them to make.
• The knowledge that life is short is an incentive to stop wasting time, focus on the things that matter most, and enjoy your life as much as you can while it lasts. If you think you’re going to live forever, you have no reason to do any of that. Scarcity makes things more valuable, including life. The belief in an everlasting afterlife devalues this life.
• If you were really going to go to heaven when you died, the logical thing to do would be to kill yourself as soon as possible, after encouraging everyone you care about to do the same. Or maybe you wouldn’t do that, since having all those deaths on your hands might prevent you from going to the right place. But still, it wouldn’t make any sense to fear death, to try to avoid it, and to be sad when people die. A rational believer in heaven would live recklessly. Who cares if you die if you’re just going to keep living? Death would be a good thing if it meant you were going to a better world. And you would be anxious for it to happen as soon as possible, before you had a chance to do anything that might prevent you from getting there. (Of course, death is not actually a good thing, and not caring about death is a terrible idea, since heaven isn’t real. But many people think it is real, which is quite a dangerous belief.)
• Having children is a terrible idea if it means there will be more people who have a good chance of ending up in hell. The existence of hell would mean that by reproducing, you risk causing infinitely more suffering than you would cause by doing any other bad thing you can imagine. Even if most people weren’t going to hell, as the Bible says they are, allowing any risk of even one person going to hell when you could have avoided it is unacceptable, and makes you an infinitely worse person than every childless criminal in history combined. The risk of causing your children to suffer forever is especially bad if people who die very young go to hell by default.
• On the other hand, if you believe that people who die very young go to heaven by default, the logical thing to do would be to reproduce as often as possible and then kill all your children as soon as possible, to maximize the number of people who go to heaven.² There certainly wouldn’t be any reason to oppose abortion if you believed that. In any case, if people who believed in heaven and hell acted logically on their misguided beliefs, believers would be extinct by now.
