You continue to shift terms, so it makes it more difficult to pin you down. My math is pretty solid - socio-economic classes are defined by values in intervals . So guessing the average income for each race would be guessing what interval? It would be guessing middle class for each race! Remember, you stated the proposition that, 'race is a good class indicator' - thus, we don't care about variance in the interval ca…

Settle down. I got the mean incomes from the table on pages 29-34, which a CTRL-F would've shown you. I chose the mean incomes because we were discussing how far off you'd be if you guessed a random person's income. Mean incomes would be the most accurate in that case. Median incomes are a perfectly fine metric as well.

The "set of classes" means nothing. If you're trying to predict someone's behavior, distinguishing someone who makes $59,999 from someone who makes $60,000 makes no sense. If it helps, pretend I said "socioeconomic status" every time I said "class". They're interchangeable to me, though the latter indeed implies discrete groups.

With that said, if you think living on $55,530 is anything like living on $34,218, you're just wrong. How can multiplying one's income by 1.6 not have a massive effect on their life?

That's ignoring the decreasing marginal utility of a dollar as incomes rise. The poverty threshold for a family of four is $22,025. Black households have a "surplus" income of $12,193. White households have a surplus income of $33,505. The average white family will find itself in a situation where theft is attractive far less often than the average black family.

"Not substantial"? Consider my mind boggled.

First of all, socioeconomic classes are artificial constructs. There's no reason to believe that there are large discontinuities in the probabilities of certain behaviors as income increases, though that is likely the case around poverty level. From the census document you linked to, here are average household incomes by race: Asian: $86,185 White, non-Hispanic: $74,102 Hispanic: $51,572 Black: $46,533 If you don't t…

[Edit: Moved up a node to reflect the actual reply]

1. Socio-econonic classes are artificial constructs - so what? The point is that race is demonstrably unable to map the set of 'people' to the set of 'classes.'

2. If you are not able to accurately quote the figures from the pdf I linked to prior, then what is the likelyhood you even read it?

The ACTUAL median incomes can be found on pages 6-7:

Asian: $65,637

White, non-Hispanic: $55,530

Average: $50,000

Black: $34,218

The differences fall in the interval known as middle-class as I said before - so for the purposes of this discussion, they are not substantial.

Based on your response, you do not even understand the terms I've been using.

'Set of classes,' means everything per this discussion - as the discussion has been premised on the statement you made (that skin color is an indicator of class).

So when you say things like...:

"If you're trying to predict someone's behavior, distinguishing someone who makes $59,999 from someone who makes $60,000 makes no sense."

..You suggest that you either do not understand my argument, or, you do not understand what has been meant by the word "class" in this discussion.

So I'll say it again; Classes are defined by an interval on the set of natural numbers. This isn't a discussion about guessing incomes with any greater precision than those provided to us by said classes.

The data provided to us by the census bureau document is the average. Note that the "households" in the census include BOTH family and non-family households.

So, when you say things like...:

"The poverty threshold for a family of four is $22,025. Black households have a "surplus" income of $12,193. White households have a surplus income of $33,505."

...You hint that you didn't quite understand that the average provided was calculated including single-households as well as non-single households with kids. So your whole reply is a bit of a straw-man...

...But it isn't even really a good one. We are talking about race as a predictor so let us control for income and work backwards. Imagine two families, one black, the other white, both living with an income of $34,218, both with four children. Is it then your contention that the Black family is still more likely to produce a thief?

If so, I do consider your mind boggled.

I have said several times that I'm not talking about discrete classes, yet you insist on arguing that point. I do not think that race can predict whether someone is lower, middle or upper class. I do think that race can predict income. I don't understand why you continue to tell me what I meant by class when I have told you what I actually meant three times.

I understand the data completely. The family of four example was an illustration of the marginal utility of income. The point is that not only are $55,530 and $34,218 quite different numerically, but they're also vastly different in terms of the luxuries a household can afford.

You've spent so much time arguing semantics that you haven't even tried to disprove my assertion that households earning $55,530 and $34,218 will likely have different behaviors. If my assertion is true, then race is a valuable predictor of behavior.

Controlling for income makes no sense, as my claim was about outward predictors of behavior. No, I don't think black families and white families with the same incomes will have significant differences in criminality. I think that data does actually show that blacks commit more crime than whites even when you control for income, but I don't think the difference is big enough for it to be a valuable predictor of behavior.

Good night.

[Edit: 'its' changed to 'opposite' for clarity, 'there' to 'their']

1. "I have said several times that I'm not talking about discrete classes, yet you insist on arguing that point."

Regardless of whether or not you meant to be "talking about discrete classes," you were. Socio-economic classes ARE discrete classes. So if you are talking about some other type of class, it is a mistake of comprehension on your behalf.

2. "I do not think that race can predict whether someone is lower, middle or upper class."

An explicit contradiction. I'll quote you directly:

"In America, skin color is a good predictor of class."

So which is it? Is race a good "predictor" of class or is it not?

3. "I do think that race can predict income."

This is the same thing as predicting class. Income is both necessary and sufficient for determining class, so if you could predict income by race, you could predict class by race. But you cannot do this (remember that guessing 'middle class' over and over is not allowed as it isn't information providing.).

4. "...you haven't even tried to disprove my assertion that households earning $55,530 and $34,218 will likely have different behaviors."

Ummm...that's because the opposite is taken for granted in the model of class. The middle class interval is traditionally considered to be from 30K to 75K - the class intervals are chosen precisely because the buying power in each strata is considered to be effectively equivalent. Again, if you don't understand this, then you do not understand the nature of classes - it just is what it is.

5. " If my assertion is true, then race is a valuable predictor of behavior."

No. Even if your assertion is true, all it shows is that income is a predictor of class. Well, duh - classes are defined by incomes. Behavior has no relation to any of these variables - that is, bad behaviors are distributed in equal proportions across the class strata. Income may predict risk-levels associated with bad-behaviors, but not necessarily their frequency.

6. "No, I don't think black families and white families with the same incomes will have significant differences in criminality."

Exactly. So then, there is no predictive ability that race has for any arbitrary class strata. It immediately follows then, that race has no predictive ability in terms of class. QED.

It's nice to see somebody making an effective argument against those high-and-mighty OkCupid data lords. I've read a number of their posts, and they are actually quite careless in making assertions as though they are experts. Anyone who works with data knows that subtle changes in how you define a metric can lead to drastically different findings. Ever heard the saying: "There are lies, damn lies, and statistics." In…

They lost me when I noticed they were mucking around with chart axes to make effects look more significant than they are ( http://news.ycombinator.com/item?id=1065203 ), surely the oldest trick in the book. Besides that, the posts can only count as pseudo-scientific in the absence of the data being available for review. But such criticisms do kind of miss the point, which is that this has been very effective marketin…

What's wrong with 'mucking around' with chart axes? Scientists do that all the time, because effects are often hardly visible with 'normal' axes and you have something you wish to make clearly stand out. Skipping part of an axis and changing the scales is a normal, even required, thing to do.

Please start throwing rocks at me, but I can also see a much simpler explanation behind the numbers than those constructed in the post. Just don't throw rocks at OkCupid, it's their job to analyze the numbers and match all those people in the best way they can. It's a nice bonus for everyone who is still on the dating scene (or in the dating website business) that OkCupid actually publishes what they find.

What is constructed in the post is not an alternative explanation of the numbers. It is an explanation of an effect that needs to be taken into account to explain the numbers. It may even dominate the explanation, but that's not asserted in the article. You have fallen into an "either-or" trap.

Maybe you read a different post, but the one linked here simply argues that "any black person will tell you, when black folks date online they don't go to OKcupid," then lists a bunch of sites targeting black users and concludes that the OKCupid data is not representative of the public at large, despite the complete absence of supporting data. I don't see an analysis of data, just a hypothesis.

Coates is pointing out that there are good reasons to suspect strong sample bias. OkCupid didn't address this -- they just assumed an unbiased sample. I find Coates' argument far more compelling than OkCupid's blind assumption. Blacks do look seriously underrepresented based on the response rates to the two questions. (Suggesting that blacks account for around 4% of OkCupid's users.) That's hardly proof of anything,…

    Coates is pointing out that there are good reasons
    to suspect strong sample bias.
If that was all he did then there wouldn't be a problem, but it wasn't. He also made unsubstantiated, anecdotal claims, and he presented the whole thing as fact.

    OkCupid didn't address this -- they just assumed an unbiased sample.
The OKCupid post very explicitly addressed how their user demographics differ from the norm.

There is another explanation of OkCupid's conclusions which is not discussed in that blog. The author of the blog even censored a comment pointing this fact out. 39% of black women are obese, compared to 23% of white women. Men prefer to date non-obese women. http://minorityhealth.hhs.gov/templates/content.aspx?ID=6456

Which explains why it is so hard to get an Asian woman to reply to you, they must be inundated with messages, presuming of course that men don't prefer obese women.

You should explicitly note this.

I've actually really liked the posts from OK Cupid, they are very interesting, but this article really pokes a lot of holes in their theories, in that they presume they are dealing with a cross section of society due to their size, but from reading this, it seems entirely likely they are mistaken.
