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?
I wouldn't say so. I think it shows that genes for higher IQ are inherited dominantly.
This has also been proposed as an explanation for the Flynn effect - whole countries getting "smarter" over time - being due to the gene pool mixing more in cities, and thus with dominant pro-IQ genes gaining ground.
The same mechanism has been proposed for the increasing height.
See, that's fine with me. You want to indulge in X because you like it, not because of rationalization Y or Z. Just like I want to indulge in chocolate. That's fine with me.
I just don't like the claim that it is morally superior. Or that it's something everyone should do. Or that it's how resources "should" be spent. If it is an indulgence, though, then indulgences are fine with me.
Btw, I'm just going to interject and say that this conversation has been done at Hacker News many times and it never really goes anywhere. I'm going to wait five years until more genome wide association studies are done before I try to enter this argument again. It seems obvious to me that there are some genetic differences in intelligence, but it's a touchy enough subject that I don't feel it's worth entering an argument based on individual interpretations of incomplete evidence.
