What the fucking shit, Barbie?

I’m back from Haiti! It was amazing and awesome, and please stand by for more about that, with cultural observations and possibly a slide show if you’re all well behaved.

Today, thanks to my math camp buddy Lenore Cowen, I am going to share with you an amazing blog post by Pamela Ribon. Her post is called Barbie Fucks It Up Again and it describes a Barbie book entitled Barbie: I Can Be a Computer Engineer

The other book is called "I Can Be an Actress"

The other book is called “I Can Be an Actress”

Just to give you an idea of the plot, Barbie’s sister finds Barbie engaged on a project on her computer, and after asking her about it, Barbie responds:

“I’m only creating the design ideas,” Barbie says, laughing. “I’ll need Steven and Brian’s help to turn it into a real game!”

To which blogger Pamela Ribon comments:
What the fucking shit, Barbie?
Update: Please check out the amazing Amazon reviews of this book (hat tip Chris Wiggins).

Alt Banking in Huffington Post #OWS

November 11, 2014 1 comment

Great news! The Alt Banking group had a piece published today in the Huffington Post entitled With Economic Justice For All, about our hopes for the next Attorney General.

For the sake of the essay, we coined the term “marble columns” to mean the opposite of “broken windows.” Instead of getting arrested for nothing, you never get arrested, as long as you work at a company with marble columns. For more, take a look at the whole piece!

Also, my good friend and bandmate Tom Adams (our band, the Tomtown Ramblers, is named after him) will be covering for me on mathbabe for the next few days while I’m away in Haiti. Please make him feel welcome!

Nerd catcalling

This is a guest post by Becky Jaffe.

It has come to my attention that I am a nerd. I take this on good authority from my students, my friends, and, as of this morning, strangers in a coffee shop. I was called a nerd three times today before 10:30 am, while I was standing in line for coffee – which is to say, before I was caffeinated, and therefore utterly defenseless. I asked my accusers for suggestions on how to be less nerdy. Here was their helpful advice:


Guy in coffee shop: “Wear makeup and high heels.”

Another helpful interlocutor: “Use smaller words.”

My student, later in the day: “Care less about ideas.”

A friend: “Think less like NPR and more like C-SPAN.”

What I wish someone had said: “Is that a dictionary in your pocket or are you happy to see me?”


What I learned today is that if I want to avoid being called a nerd, I should be more like Barbie. And I don’t mean the Professor Barbie version, which – get this – does not exist. When I googled “Professor Barbie,” I got “Fashion Professor Barbie.”


So many lessons in gender conformity for one day! This nerd is taking notes.

Tailored political ads threaten democracy

Not sure if you saw this recent New York Times article on the new data-driven political ad machines. Consider for example, the 2013 Virginia Governor campaign won by Terry McAuliffe:

…the McAuliffe campaign invested heavily in both the data and the creative sides to ensure it could target key voters with specialized messages. Over the course of the campaign, he said, it reached out to 18 to 20 targeted voter groups, with nearly 4,000 Facebook ads, more than 300 banner display ads, and roughly three dozen different pre-roll ads — the ads seen before a video plays — on television and online.

Now I want you to close your eyes and imagine what kind of numbers we will see for the current races, not to mention the upcoming presidential election.

What’s crazy to me about the Times article is that it never questions the implications of this movement. The biggest problem, it seems, is that the analytics have surpassed the creative work of making ads: there are too many segments of populations to tailor the political message to, and not enough marketers to massage those particular messages for each particular segment. I’m guessing that there will be more money and more marketers in the presidential campaign, though.

Translation: politicians can and will send different messages to individuals on Facebook, depending on what they think we want to hear. Not that politicians follow through with all their promises now – they don’t, of course – but imagine what they will say when they can make a different promise to each group. We will all be voting for slightly different versions of a given story. We won’t even know when the politician is being true to their word – which word?

This isn’t the first manifestation of different messages to different groups, of course. Romney’s famous “47%” speech was a famous example of tailored messaging to super rich donors. But on the other hand, it was secretly recorded by a bartender working the event. There will be no such bartenders around when people read their emails and see ads on Facebook.

I’m not the only person worried about this. For example, ProPublica studied this in Obama’s last campaign (see this description). But given the scale of the big data political ad operations now in place, there’s no way they – or anyone, really – can keep track of everything going on.

There are lots of ways that “big data” is threatening democracy. Most of the time, it’s by removing open discussions of how we make decisions and giving them to anonymous and inaccessible quants; think evidence-based sentencing or value-added modeling for teachers. But this political campaign ads is a more direct attack on the concept of a well-informed public choosing their leader.

The war against taxes (and the unmarried)

The American Enterprise Institute, conservative think-tank, is releasing a report today. It’s called For richer, for poorer: How family structures economic success in America, and there is also an event in DC today from 9:30am til 12:15pm that will be livestreamed. The report takes a look at statistics for various races and income levels at how marriage is associated with increased hours works and income, for men especially.

It uses a technique called the “fixed-effects model,” and since I’d never studied that I took a look at it on the wikipedia page, and in this worked-out example on Josh Blumenstock’s webpage of massage prices in various cities, and in this example, on Richard William’s webpage, where it’s also a logit model, for girls in and out of poverty.

The critical thing to know about fixed effects models is that we need more than one snapshot of an object of interest – in this case a person who is or isn’t married – in order to use that person as a control against themselves. So in 1990 Person A is 18 and unmarried, but in 2000 he is 28 and married, and makes way more money. Similarly, in 1990 Person B is 18 and unmarried, but in 2000 he is 28 and still unmarried, and makes more money but not quite as much more money as Person A.

The AEI report cannot claim causality – and even notes as much on page 8 of their report – so instead they talk about a bunch of “suggested causal relationships” between marriage and income. But really what they are seeing is that, as men get more hours at work, they also tend to get married. Not sure why the married thing would cause the hours, though. As women get married, they tend to work fewer hours. I’m guessing this is because pregnancy causes both.

The AEI report concludes, rightly, that people who get married, and come from homes where there were married parents, make more money. But that doesn’t mean we can “prescribe” marriage to a population and expect to see that effect. Causality is a bitch.

On the other hand, that’s not what the AEI says we should do. Instead, the AEI is recommending (what else?) tax breaks to encourage people to get married. Most bizarre of their suggestions, at least to me, is to expand tax benefits for single, childless adults to “increase their marriageability.” What? Isn’t that also an incentive to stay single and childless?

What I’m worried about is that this report will be cleverly marketed, using the phrase “fixed effects,” to make it seem like they have indeed proven “mathematically” that individuals, yet again, are to be blamed for the structural failure of our nation’s work problems, and if they would only get married already we’d all be ok and have great jobs. All problems will be solved by tax breaks.

What male allies should *really* be doing

Chris Wiggins was kind enough to forward me this article on a recent panel discussion of “Male Allies of Women” at the 2014 Grace Hopper Celebration, which is a big deal conference for women in tech.

Panelists included Facebook CTO Mike Schroepfer, Google’s SVP of Search Alan Eustace, GoDaddy CEO Blake Irving, and Intuit CTO Tayloe Stansbury. The advice was stale and trite and included things like “speak up,” “lean in,” and “get excited about your ideas like men do.”

Yes, I said GoDaddy.

Yes, I said GoDaddy.

By far the best part was the audience response – I wish I’d been there just for that part.

There was a Bingo game on the phrases that were anticipated:



What male allies should really be doing, step 1

Here’s the thing. If you haven’t seen this video of gamer Anita Sarkeesian speaking at the Feminist Frequency conference (hat tip Josh Vekhter), go take a look. It’s a fantastic and articulate diatribe against sexism and misogyny, and it ends with a super reasonable request of the men in the audience and in the world:

Trust women who say they experience sexism.

What’s amazing to me is how hard this is to hear for men in my life. When I repeated this to a couple of them, they actually said that I didn’t experience the stuff that I had. It was kind of nuts, and I had to point out to them that they were failing on the most basic level.

Yes, it requires empathy, and observation, and yes it sucks, because once you start seeing it you will be disappointed in the world. Tough shit, it’s reality.

What male allies should really be doing, step 2

Once men start trusting the women they love and admire and work with, then the next thing they can do is start acting on that knowledge.

I don’t know how many times I’ve been the target of sexism in front of other men and somehow it’s my job to confront it and deal with it. Men, step the fuck up and, when you see sexism happening, once you can manage that, defend the target and put a stop to it. Speak up and defend your friend, or your wife, or your daughter, or your colleague. Thanks.

Detroit’s water problem and the Koch brothers

Yesterday at the Alt Banking group we discussed the recent Koch brothers article from Rolling Stone Magazine, written by Tim Dickinson. You should read it now if you haven’t already.

There are tons of issues that came up, but one of them in particular was the control of information that the Koch brothers maintain over their activities. If you read the article, you realize that the brothers are die-hard libertarians but at some point realized that saying out loud that they are die-hard libertarians was working against them, specifically in terms of getting into trouble for polluting the environment with their chemical factories, so instead they started talking about how much they love the environment and work to protect it.

It’s not that they stopped polluting, it’s that their rhetoric changed. In fact there’s no reason to think they stopped polluting, since they still had plenty of regulators going after them for various violations. Since their apparent change of heart they’ve also decided to be publicly philanthropic, giving money to hospitals, and Lincoln Center, and even PBS (see how that worked out on Stephen Colbert).

The problem with all this window dressing is that people are actually starting to think the Koch brothers may be good guys after all, and what with the fancy lawyers that the Koch brothers hire to control information about them, the public view is very skewed.

For example, how many economists have they bought and inserted into universities nationwide? We will never really know. There’s no way we can keep a score sheet with “good deeds” on one side and “shitty deeds” on the other. We don’t have enough information for the second side.

The exception to this information control is when they get in trouble with regulators and it becomes a matter of public record. And thank goodness those court documents exist, and thank goodness investigative journalist Tim Dickinson did all the work he did to explain it to us.

A couple of conclusions. First, we complain a lot about the bank settlements for the misdeeds of the big banks. Nobody went to jail, and the system is just as likely to repeat this kind of thing again as it was in 2005. But another problem with this out-of-court settlement process, we now realize, is that we actually don’t know what happened except in big, vague terms. There will be no Tim Dickinson reporting on big banks.

Second, the connection to Detroit. Right now there are 15,000 residents of Detroit whose water has been shut down, basically so they can privatize the water system with the best deal from Wall Street. They owe less than $10 million, on average a measly $540. The United Nations has called this water shutoff a violation of the human rights of the people of Detroit.

If you feel bad about that, you can donate to someone’s water bill directly, which is kind of neat.

Or is it? Shouldn’t Obama be declaring Detroit a state of emergency? Wouldn’t we be doing that in another city that had 15,000 residents without water? Why is this an exception to that rule? Because the victims are poor? Don’t we recognize Detroit as a place where it’s unusually difficult to find work? Are we going to allow people to shut off heat as well, once winter comes?

Once you think about it, the idea of a “private solution” to the Detroit water emergency seems wrong. In fact, you can almost imagine David Koch coming to the rescue here, as part of his “positive optics” campaign, and bailing out the Detroit citizens and then, for good measure, buying up the water system altogether. A hero!

And if you’re in that mode, you can think about the asymptotic limit of that approach, whereby a few very rich people gradually take control of resources, and then there are intermittent famines of various types in different cities, and the rich people swoop in and heroically save the day whilst scooping up even more ownership of what used to be public infrastructure. And we might thank them every time, because it was a dire situation and they didn’t really need to do that with all their money.

It’s frustrating to live in a country that has so many resources but which can’t seem to get it together to meet the basic human needs of its citizens. We need a basic income, at least for the people in Detroit, at least right now.
