The problem with the Amanda Knox case is not scale, but distance. The farther away something is, the less influence I have over it, and the less influence it can have over me. Amanda Knox is far away in every sense - it's in a different country, a different time (the court case is already over), and a different language. It's like watching a year old YouTube video of an already-fired policeman from a town I've never heard of abusing his power - lots of people do it, but it's just getting riled up for no reason.
On the other hand, the point of the original Less Wrong Amanda Knox article wasn't that we should care about the real event, but as a rationality test case. A similar fictional story would've worked just as well, but using a real news story guaranteed that it'd be free of the distortions that come with writing fiction.

o_0 If only. Journalism is telling stories about the world.[1] The primary sources of history are stories, put together by humans. And just because the humans in question were contemporaneous doesn't mean the stories are in any way free of most of the distortions of fiction.

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?
