A Simpler Version of Pascal's Mugging Background: I found Bostrom’s original piece (https://www.nickbostrom.com/papers/pascal.pdf) unnecessarily confusing, and numerous Fellows in the EA VP Intro Fellowship have also been confused by it. I think we can be more accessible in our ideas. I wrote this in about 30 minutes though, so it's probably not very good. I would greatly appreciate feedback on how to improve it. I also can't decide if it would be useful to have at the end a section of "possible solution" because as far as I can tell, theses solutions are all subject to complicated philosophical debate that goes over my head. So including it might be necessarily too confusing. Might be easiest to provide comments on the Google Doc itself (https://docs.google.com/document/d/1NLfDK7YqPGdYocxBsTX1QMldLNB4B-BvbT7sevPmzMk/edit)
Pascal is going about his day when he is approached by a mugger demanding Pascal’s wallet. Pascal refuses to give over his wallet, at which point the mugger offers the following deal: “Give me your wallet now and tomorrow I will give you twice as much money as is in the wallet now” Pascal: “I have $100 in my wallet, but I don’t think it’s very likely you’re going to keep your promise” Mugger: “What do you think is the probability that I keep my promise and give you the money?” Pascal: “Hm, maybe 1 in a million because you might be some elaborate YouTube prankster” Mugger: “Ok, then you give me your $100 now, and tomorrow I will give you $200 million” Let’s do the math. We can calculate expected value by multiplying the value of an outcome by the probability of that outcome. The expected value of taking the deal, based on Pascal’s stated belief that the mugger will keep their word, is 200,000,000 * 1/(1,000,000) = $200. Whereas, the expected value of not taking the deal is $100 * 1 (certainty) = $100. Pascal should take the deal if he is an expected value maximizing person. Maybe at this point Pascal realizes that the chances of the mugger having 200 million dollars is extremely low. But this doesn’t change the conundrum because the mugger will simply offer more money to account for the lower probability of them following through. For example, Pascal thinks the probability of the mugger having the money decreases the chance of the mugger following through to one in a trillion. Then the mugger offers 200 trillion dollars. The mugger is capitalizing on the fact that everything we know, we know with a probability less than one. We can not be 100% certain that the mugger won’t follow through on their promise, even though we intuitively know they won’t. Extremely unlikely outcomes are still possible.
Pascal: “200 trillion dollars is too much money, in fact I don’t think I would benefit from having any more than 10 million dollars” Pascal is drawing a distinction between expected value (uses units of money) and expected utility (uses units of happiness, satisfaction, other things we find intrinsically valuable), but the mugger is unphased.
Mugger: “Okay, but you do value happy days of life in such a way where more happy days is always better than fewer happy days. It turns out that I’m a wizard and I can grant you 200 trillion happy days of life in exchange for your wallet” Pascal: “It seems extremely unlikely that you’re a wizard, but the amount I value 200 trillion happy days of life is so high that the expected utility is still positive, and greater than what I get from just keeping my $100” Pascal hands his wallet to the mugger but doesn’t feel very good about doing so.
So what’s the moral of this story? -Expected value is not a perfect system for making decisions, because we all know Pascal is getting duped. -We should be curious and careful about how to deal with low probability events with super high or low expected value (like extinction risks). Relatedly, common sense seems to suggest that spending effort on too unlikely scenarios is irrational
Progressives might be turned off by the phrasing of EA as "helping others." Here's my understanding of why. Speaking anecdotally from my ongoing experience as a college student in the US, mutual aid is getting tons of support among progressives these days. Mutual aid involves members of a community asking for assistance (often monetary) from their community, and the community helping out. This is viewed as a reciprocal relationship in which different people will need help with different things and at different times from one another, so you help out when you can and you ask for assistance when you need it; it is also reciprocal because benefiting the community is inherently benefiting oneself. This model implies a level field of power among everybody in the community. Unlike charity, mutual aid relies on social relations and being in community to fight institutional and societal structures of oppression (https://ssw.uga.edu/news/article/what-is-mutual-aid-by-joel-izlar/).
"[Mutual Aid Funds] aim to create permanent systems of support and self-determination, whereas charity creates a relationship of dependency that fails to solve more permanent structural problems. Through mutual aid networks, everyone in a community can contribute their strengths, even the most vulnerable. Charity maintains the same relationships of power, while mutual aid is a system of reciprocal support." (https://williamsrecord.com/376583/opinions/mutual-aid-solidarity-not-charity/).
Within this framework, the idea of "helping people" often relies on people with power aiding the helpless, but doing so in a way that reinforces power difference. To help somebody is to imply that they are lesser and in need of help, rather than an equal community member who is particularly hurt by the system right now. This idea also reminds people of the White Man's Burden and other examples of people claiming to help others but really making things worse.
I could ask my more progressive friends if they think it is good to help people, and they would probably say yes – or at least I could demonstrate that they agree with me given a few minutes of conversation – but that doesn't mean they wouldn't be peeved at hearing "Effective Altruism is about using evidence and careful reasoning to help others the best we can"
I would briefly note that mutual aid is not incompatible with EA to the extent that EA is a question; however, requiring that we be in community with people in order to help them means that we are neglecting the world's poorest people who do not have access to (for example) the communities in expensive private universities.
I think many progressives and others on the left value mutual aid because they see it as more sustainable and genuine and with fewer negative strings attached. I think they are generally fine with aid and helping others as long as they can be shown good evidence that 1) the aid is not going to be used to prevent other positive changes (basically things like exchanging humanitarian aid for continued resource extraction from a region that's worth more than the total aid contributed, or pressuring/requiring a housing justice org to stop organizing tenants to stand up for their rights in exchange for more funding for their shelter initiatives) and 2) Aid is done in a competent manner so that it doesn't get stolen by governments, wasted, or taken by other corrupt actors and 3) respects local wisdom and empowers people to have more of a say over decisions that most affect them. Another example would be conservation efforts that kick indigenous people off their land vs ones that center their practical experience and respect their rights.
There's a big difference between donating to a food bank and creating the infrastructure for people to organize their own food bank and/or grow their own food of their choosing. The first one is more narrowly focused on food security whereas the latter fits with a broader food justice or food sovereignty approach. I think both are important. Many people believe the latter kind of empowerment initiatives are more sustainable in the long run and less dependent on shifts in funding, even if they're harder to set up initially. The reason being that they redistribute power, not just resources. To sum it up, something like "Give a man a fish and he will eat for a day; teach a community to fish, and give them a place to do so, and they will eat for generations."
Thanks for your response! I don't think I disagree with anything you're saying, but I definitely think it's hard. That is, the burden of proof for 1, 2, and 3 is really high in progressive circles, because the starting assumption is charity does not do 1, 2, or 3. To this end, simplified messages are easily mis-interpreted.
I really like this: "The reason being that they redistribute power, not just resources."
Yeah when I was reading it I was thinking "these are high bars to reach" but I think they cover all the concerns I've heard. Oh glad you liked it! I probably could have said that from the start, now that I think about it.
