(which is not the same as killing somebody but that's a different point)
Actually, this is exactly the point. My comment is directly addressing an explanation for this claim:
[E]very time you get your hair cut, or go to a movie, or drink a Starbucks latte, you're killing someone.
This claim was backed up with this paragraph:
By spending that money on yourself, instead of sending it to buy bags of rice for a famine-stricken region, or mosquito nets for malaria-ridden countries, or tin wood stoves, or water pumps, or water filters, or transparent plastic bottles, or latrines, or condoms, or any of the various simple and inexpensive supplies or devices that aid agencies are distributing around the world.
Your point is still very valid, which is why I went out of my way to say this:
EDIT: I really don't want to give the impression that you shouldn't give money or help people less fortunate than yourself. I think these are great things. I just don't understand the jump from "I bought a latte" to "I killed people."
The point I'm responding to is:
Why are you carrying the moral burden?
Because everyone is. I'm assuming you meant that comment as saying something like the burden is diluted since so many people touch the money, but I don't think that is valid.
During a recent discussion with komponisto about why my fellow LWers are so interested in the Amanda Knox case, his answers made me realize that I had been asking the wrong question. After all, feeling interest or even outrage after seeing a possible case of injustice seems quite natural, so perhaps a better question to ask is why am I so uninterested in the case.
Reflecting upon that, it appears that I've been doing something like Eliezer's "Shut Up and Multiply", except in reverse. Both of us noticed the obvious craziness of scope insensitivity and tried to make our emotions work more rationally. But whereas he decided to multiply his concern for individuals human beings by the population size to an enormous concern for humanity as a whole, I did the opposite. I noticed that my concern for humanity is limited, and therefore decided that it's crazy to care much about random individuals that I happen to come across. (Although I probably haven't consciously thought about it in this way until now.)
The weird thing is that both of these emotional self-modification strategies seem to have worked, at least to a great extent. Eliezer has devoted his life to improving the lot of humanity, and I've managed to pass up news and discussions about Amanda Knox without a second thought. It can't be the case that both of these ways to change how our emotions work are the right thing to do, but the apparent symmetry between them seems hard to break.
What ethical principles can we use to decide between "Shut Up and Multiply" and "Shut Up and Divide"? Why should we derive our values from our native emotional responses to seeing individual suffering, and not from the equally human paucity of response at seeing large portions of humanity suffer in aggregate? Or should we just keep our scope insensitivity, like our boredom?
And an interesting meta-question arises here as well: how much of what we think our values are, is actually the result of not thinking things through, and not realizing the implications and symmetries that exist? And if many of our values are just the result of cognitive errors or limitations, have we lived with them long enough that they've become an essential part of us?
