Wage Gaps Don’t Magically Get Smaller Because Big Data

Today, just a rant. Sorry. I mean, I’m not a perfect person either, and of course that’s glaringly obvious, but this fluff piece from Wired, written by Pam Wikham of Raytheon, is just aggravating.

The title is Big Data, Smaller Wage Gap? and, you know, it almost gives us the impression that she has a plan to close the wage gap using big data, or alternatively an argument that the wage gap will automatically close with the advent of big data techniques. It turns out to be the former, but not really.

After complaining about the wage gap for women in general, and after we get to know how much she loves her young niece, here’s the heart of the plan (emphasis mine, on the actual plan parts of the plan):

Analytics and microtargeting aren’t just for retailers and politicians — they can help us grow the ranks of executive women and close the gender wage gap. Employers analyze who clicked on internal job postings, and we can pursue qualified women who looked but never applied. We can go beyond analyzing the salary and rank histories of women who have left our companies. We can use big data analytics to tell us what exit interviews don’t.

Facebook posts, Twitter feeds and LinkedIn groups provide a trove of valuable intel from ex-employees. What they write is blunt, candid and useful. All the data is there for the taking — we just have to collect it and figure out what it means. We can delve deep into whether we’re promoting the best people, whether we’re doing enough to keep our ranks diverse, whether potential female leaders are being left behind and, importantly, why.

That’s about it, after that she goes back to her niece.

Here’s the thing, I’m not saying it’s not an important topic, but that plan doesn’t seem worthy of the title of the piece. It’s super vague and fluffy and meaningless. I guess, if I had to give it meaning, it would be that she’s proposing to understand internal corporate sexism using data, rather than assuming “data is objective” and that all models will make things better. And that’s one tiny step, but it’s not much. It’s really not enough.

Here’s an idea, and it kind of uses big data, or at least small data, so we might be able to sell it. Ask people in your corporate structure what the actual characteristics are of people they promote, and how they are measured, or if they are measured, and look at the data to see if what they say is consistent with what they do, and whether those characteristics are inherently sexist. It’s a very specific plan and no fancy mathematical techniques are necessary, but we don’t have to tell anyone that.

What combats sexism is a clarification and transparent description of job requirements and a willingness to follow through. Look at blind orchestra auditions for a success story there. By contrast, my experience with the corporate world is that, when hiring or promoting, they often list a long series of unmeasurable but critical properties like “good cultural fit” and “leadership qualities” that, for whatever reason, more men are rated high on than women.

The re-emergence of debtors’ prisons

Yesterday at my weekly Occupy meeting we watched videos called To Prison For Poverty by Brave New Films (Part I and Part II) before discussing them. Take a look, they are well done:

 

It’s not the first time this issue has come up recently; the NPR investigations into court fees from last May, called Guilty and Charged, led to a bunch of reports on issues similar to this. Probably the closest is the one entitled Unpaid Court Fees Land The Poor In 21st Century Debtors’ Prisons.

A few comments:

  • Ferguson is now famous for having a basically white police force patrolling a basically black populace. But it also has this fines-and-fees-and-jails problem: fines and fees associated to mostly traffic violations accounted for 21% of the city’s budget in 2013. And there were more arrest warrants than people in Ferguson last year, mostly for non-violent offenses.
  • But the debtors’ prison problem isn’t just a racial issue. The people profiled in the above video were white, which could have been a documentarian’s decision, but in any case is a fact: the poverty-to-prison system is screwing all poor people, not just minorities. This is in spite of the fact that the Supreme Court found it unconstitutional in the landmark 1983 case, Bearden v. Georgia.
  • This sense that “everyone is screwed” creates solidarity among poor whites and poor blacks, and especially young people. The Ferguson protests have been multi-racial, for example. And if you’ve read The New Jim Crow by Michelle Alexander, you’ll recognize a historical pattern whereby political change happens when poor whites and poor blacks start working together.
  • One interesting and scary question to emerge from the above stories is, how did so many fees and fines get attached to low-level misdemeanors in the first place? It seems like privatized probation and prison companies have a lot to do with it.
  • In some cases, they are putting people in jail for days and weeks, which costs the government hundreds of dollars, in order to capture a small fee. That makes no sense.
  • In other cases, the fees accumulate so fast that the poor person who committed the misdemeanor ends up being responsible for an outrageous amount of money, far surpassing the scale of the original misdeed, and all because they are poor. That also makes no sense.
  • It’s not just for prisons either; all sorts of functions that we consider governmental functions have been privatized, like health and human services: child welfare services, homeless services, half-way houses, and more.
  • In the worst cases, the original intent of the agency (“putting people on probation so they don’t have to be in jail”) has been perverted into an entirely different beast (“putting them in jail because they can’t pay their daily $35 probation fees”). The question we’d like to investigate further is, how did that happen and why?

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).
BEST UPDATE EVER (hat tip Marko): BARBIE CAN CODE REMIXED

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.”

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.
