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've been looking for about a decade now, but have not encountered evidence that would discredit Lynn. I have however seen a lot of evidence which corroborates his findings.
If you have evidence that discredits his work, I would appreciate it.
Why stop at Africa then? Shouldn't we invest billions in animal shelters, so that dogs and cats can live long lives until we find a way to bypass their genetic disadvantage? Wouldn't those be just as "massive benefits"?
Perhaps it came across as smugness, but I do find that every piece of news I see, either from South Africa, or from Haiti, or from Nigeria, or from Zimbabwe, or from Turks and Caicos, just adds to the pile of evidence.
Also, I myself live in a place like that. Which is why I suggest (in all seriousness!) that people should consider visiting a country like South Africa for a while.
There's no better cure for academic distance than direct contact with the hard facts on the ground.
African-American IQ in the 80s, with only 20% European admixture, shows that African IQs are depressed by environment. The Dickens-Flynn model explains how to reconcile the Flynn effect and heritability increasing with age: gene-environment interactions, suggesting that any genetic difference would be amplified by feedback environmental effects. Even Jensen gives a chunk of the gaps to environment.
Animals have short lives so it wouldn't work well, and I care less about them than people with long term plans hopes and fears.
