Facebook Ad Platform Could Be Inherently Discriminatory, Researchers Say (theregister.co.uk) 104

Posted by BeauHD from the inherent-biases dept.
Researchers from Northeastern Unviersity, the University of Southern Carolina, and tech accountability non-profit Upturn have released a paper that says Facebook's ad delivery system itself can steer ads intended to be inclusive toward discrimination without explicit intent. "In a paper titled, 'Discrimination through optimization: How Facebook's ad delivery can lead to skewed outcomes,' co-authors Muhammad Ali, Piotr Sapiezynski, Miranda Bogen, Aleksandra Korolova, Alan Mislove, and Aaron Rieke find that advertiser budgets and ad content affect ad delivery, skewing it along gender and racial lines even when neutral ad targeting settings are used," reports The Register. From the report: The researchers found that Facebook ads tend to be shown to men because women tend to click on ads more often, making them more expensive to reach through Facebook's system. That divide becomes apparent when ad budgets are compared, because the ad budget affects ad distribution. As the paper explains, "the higher the daily budget, the smaller the fraction of men in the audience." Such segregation may be appropriate and desirable for certain types of marketing pitches, but when applied to credit, employment and housing ads, the consequences can be problematic.

Ad content -- text and images -- also has a strong effect on whether ads get shown to men or women, even when the bidding strategy is the same and gender-agnostic targeting is used. In particular, the researchers found images had a surprisingly large effect on ad delivery. Ad URL destination has some effect -- an ad pointing to a bodybuilding site and an ad pointing to a cosmetics site had a baseline delivery distribution of 48 percent men and 40 percent men respectively. The addition of a title and headline doesn't change that much. But once the researchers added an image to the ad, the distribution pattern changed, with the bodybuilding site ad reaching an audience that was 75 percent male and the cosmetics ad reaching an audience that was 90 percent female. According to the researchers, their tests suggest, "Facebook has an automated image classification mechanism in place that is used to steer different ads towards different subsets of the user population." "In terms of credit, employment and housing ads, the problem with this system is that it discriminates where it shouldn't: Five ads for lumber industry jobs were delivered to an audience that was more than 90 percent men and more than 70 percent white; five ads for janitorial work were delivered to an audience that was more than 65 percent women and 75 percent black," the report adds. "Housing ads also showed a racial skew."

The latest findings come after years of criticism of Facebook's ad system. Last month, Facebook announced changes to the platform intended to prevent advertisers from deploying unfair credit, employment and housing ads. One week later, the U.S. Department of Housing and Urban Development sued Facebook for violating the Fair Housing Act.

      I think the idea is that the man's click is more valuable since they're less likely to do it. Without reading the article (hey, its slashdot) logically this would actually favour women because the advertiser would get more impressions per dollar.

      Also worth pointing out that this also existed before Facebook, advertisers chose which magazines to place ads in, for example Vanity Fair vs GQ.

      "reached" means the person saw your ad.

      Often advertisers will pay based on how often their ad is clicked. So let's say it costs you $1 per click. If 1% of men and 3% of women click on your ad, then to reach 100 men costs $1, while reaching 100 women costs $3. An while women click on ads more often, they are not necessarily making a purchases at the same rate.
      So at the end of the day $3 could reach 300 men and make 2 direct sales, while $3 would only reach 100 women and also only make 2 direct sales. Howeve

      I can explain this. Women like to window-shop. So they may click on the same ad multiple times (I've done this) on different days and see if the price has changed, or if a product is back in stock. Men do not do this. Men want to buy the thing now, and don't do comparison shopping for pretty much anything that isn't a big-ticket purchase.

      The problem is that a women's "ad vote" is not weighted the same as an man's "ad vote", and thus Men are more likely to block ads (out of spite for news sites especially, b

    It's always been this way. Why do you think network ratings are based on age demographics? Companies spend more money to target younger audiences because guess what! Younger audiences watch less TV. It's to get ads in front of them so companies spend more money putting ads on shows that tend to attract younger audiences*. Older audiences watch more of it. At a certain point, they watch so much it's cheap and easy to reach their eyeballs.

    Certain brands target certain ages, sexes, incomes, even races. Just because "the internet!" doesn't suddenly make this a new.

    *Yes, yes, I know. No one under 50 watches network TV anymore, but this is how it has always worked and that's the point: it's not some new problem brought on by the face books.

    • Not quite.

      The intent isn't simply to get your ad in front of as many eyeballs as possible. Down that path lay madness. It's about getting your ad in front of as many eyeballs as possible that are attached to disposable income.

      That's why the 18-34 demographic is so coveted; They're more likely to have the cash to burn AND they are more likely to make emotional decisions ( although how true that is anymore is the subject of debate )

        The intent isn't simply to get your ad in front of as many eyeballs as possible.

        I never said that. I said they spend money to target an audience that's harder to target due to their habits. The older people get, the more likely it is they will be exposed to more ads each night, the cheaper it is to advertise to them.

        It's about getting your ad in front of as many eyeballs as possible that are attached to disposable income.

        Actually older demographics have more disposable income, not younger ones. This is why luxury items tend to be targeted to the middle aged crowd. 18-34 is so coveted because they are harder to get ads in front of and companies want to begin building their brands in those "new" consumer eyes. This is why, for example, beer companies target younger audiences. If you are 35, you probably already have a preferred brand. If you are a new drinker (let's pretend you're 21) you are still figuring that out. But to get those new drinkers, you have to get your banding and ads to them. That's harder to do since they don't sit at home watching TV from 6-10pm every night. So shows that attract them can command higher rates. Hell how do you think the CW stays in business? Their overall ratings are extremely low, but a lot of their shows skew younger than most other network shows. This allows for an opportunity for advertisers to target an audience that normally doesn't watch a lot of other broadcast network shows.

        • Actually older demographics have more disposable income, not younger ones.

          Kinda. The older demographics have more money, but they A) have more fiscal responsibilities ( such as families and retirement ) and B) Aren't as easy to manipulate.

          Meanwhile, the younger crowd may have less money, but they have fewer obligations AND are more likely to make emotional decisions.

    That is discriminatory and illegal. The researchers looked at lots of factors, including areas where targeting is acceptable practice. They wanted to know if Facebook was using their targeting algorithm where it should not be used. The answer seems to be that Facebook is breaking the law.

        Could you elaborate how a generic targeting algorithm can "discriminate".

        A generic ad optimization algorithm will create a bunch of proxy variables that effectively work like the non-discriminating factor, even if it's explicitly denied access to that variable. It's actually a lot harder to avoid than to do, basically treat every time you show an ad like an experiment. If you click the ad it counts for every property about you, if you don't click the ad it counts against every property about you. So you say it's not to discriminate on sex, the algorithm doesn't get your gender. But it'll pretty soon figure out whether people who are fans of Justin Bieber and a million other gender-skewed metrics respond to your ad or not.

        It's absolutely feasible to build an algorithm that tries to find relevant candidates while respecting an imposed equality, for example that they draw from separate pools so you must have half male and half female ad impressions. But it gets pretty hard when you want for example a jobs ad that doesn't discriminate on ethnicity, like if the population is 50-30-15-5 percent something you want a 50-30-15-5 percent distribution. It gets really hard if you don't want to discriminate on religion, sexual orientation, political stance or something else where you don't actually have the underlying data but you're pretty sure your proxy variables are effectively filtering on that anyway.

        If you're going to reply with "how's an algorithm that's only preserving the status quo or amplifying a feedback loop that's already there discriminatory" well if it was up to an algorithm an all-white school would stay all-white. After all there's never been a black person attending this school, so there's no reason to try to make a black kid apply. It's a feedback loop that'll keep bashing those unlikely to succeed because they're unlikely to succeed, even if they as individuals are doing everything they can. If you're constantly going to measured against what people "like you" do you'll never truly be in charge of your own destiny, which is kinda the essence of the American dream.
