Okay. Voting rights.
But we're not going to restrict voting rights based on IQ, because that's not the discussion. No, we're going to restrict voting rights based on how we partition you into groups (you don't get to decide what group you belong to, incidentally, we decide that as well).
I've decided you belong to the "racist" group, and are therefore part of a group whose average IQ falls below our minimum IQ. Sorry, you're not allowed to vote.
You don't think that grouping is fair? Indeed, you never made any racist arguments at all here, and only made an unrelated point about in-group bias and that it might just be a good thing? Well, you're not in my group, and I prefer to favor myself and my group, so it doesn't really matter how I classify you, the important thing to me is that I classify you as a lower-ranked "other", the specifics of which don't really matter as long as I have relative advantage over you in the classification.
I mean, you were arguing this is a useful way to behave. So why shouldn't I behave this way?
I don't think the post you were replying to was saying that we should restrict voting rights based on either IQ or group partitions that are correlated with IQ (or at all, for that matter).
This sort of thinking seems bad:
This sort of thinking seems socially frowned upon, but accurate:
Similar points could be made by replacing a/b with [group of people]. I think it's terrible to say something like:
But to me, it doesn't seem wrong to say something like:
Credit and accountability seem like good things to me, and so I want to live in a world where people/groups receive credit for good qualities, and are held accountable for bad qualities.
I'm not sure though. I could see that there are unintended consequences of such a world. For example, such "score keeping" could lead to contentiousness. And perhaps it's just something that we as a society (to generalize) can't handle, and thus shouldn't keep score.
