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?
It seems like a drastic overgeneralization to say that the cost-benefit calculation will always come out negative when charity is used outside of that context.
For instance, I'm sympathetic to your argument when applied to giving money to a homeless person in my neighborhood who looks like they might buy liquor with it, far less so when you denounce efforts to aid starving people in countries that remain poor after having been essentially pillaged by my ancestors and yours. How are these people "dysfunctional and destructive"?
Haiti and Africa are not the way they are because anyone pillaged them. You need to read types of books you do not want to read, or try to live among them for a while, to get a glimpse of the nature of their dysfunction.
Or ask yourself this question. Many Asian countries are poor, but among them, some are marvelously prosperous. How come, though, there is no Singapore of African descent?
