It's really difficult to 'shut up and multiply' in some cases.
I mean, I'm going to get personal here because it feels like the best way to articulate my problems with mathematical utilitarianism. But right now, I don't produce anything like what I cost my society (in terms of socialized medicine, and support I receive from my parents).
I feel very strongly that I shouldn't value myself more than a random African. But there are charities that claim I could save at least one life with what I spend on prescription fees every month. In terms of pure utilitarianism, unless I'm certain that I'm going to produce a lot more in the future and give some of that away, I probably ought to persuade my parents to give the help they give me with the rent to effective charities, borrow a bunch of money and give that to effective charities, then give the money I spend on my meds to effective charities until I basically kill myself.
That doesn't feel right, but it's what I get from shutting up and multiplying.
Maybe this means your feelings are wrong, and you should value yourself more than a random African.
If you go outside LW and EA, the idea that anyone values themselves only as much as a random other person would be considered bizarre.
I'd like to hear from people about a process they use to decide how much to give to charity. Personally, I have very high income, and while we donate significant money in absolute terms, in relative terms the amount is <1% of our post-tax income. It seems to me that it's too little, but I have no moral intuition as to what the right amount is.
I have a good intuition on how to allocate the money, so that's not a problem.
Background: I have a wife and two kids, one with significant health issues (i.e. medical bills - possibly for life), most money we spend goes to private school tuition x 2, the above mentioned medical bills, mortgage, and miscellaneous life expenses. And we max out retirement savings.
If you have some sort of quantitative system where you figure out how much to spend on charity, please share. If you just use vague feelings, and you think there can be no reasonable quantitative system, please tell me that as well.
Update: as suggested in the comments, I'll make it more explicit: please also share how you determine how much to give.
