Most people don't have any association in their minds with what they do and with ethics. They think they somehow moved past the questions of morality or values or ethics, and that's something that I've never imagined to be true. Cathy O'Neil More Quotes by Cathy O'Neil More Quotes From Cathy O'Neil We can't just throw something out there and assume it works just because it has math in it. Cathy O'Neil assuming math There are lots of different ways that algorithms can go wrong, and what we have now is a system in which we assume because it's shiny new technology with a mathematical aura that it's perfect and it doesn't require further vetting. Of course, we never have that assumption with other kinds of technology. Cathy O'Neil auras technology perfect By construction, the world of big data is siloed and segmented and segregated so that successful people, like myself - technologists, well-educated white people, for the most part - benefit from big data, and it's the people on the other side of the economic spectrum, especially people of color, who suffer from it. They suffer from it individually, at different times, at different moments. They never get a clear explanation of what actually happened to them because all these scores are secret and sometimes they don't even know they're being scored. Cathy O'Neil data successful white When I think about whether I want to take a job, I don't just think about whether it's technically interesting, although I do consider that. I also consider the question of whether it's good for the world. Cathy O'Neil jobs interesting thinking I know how models are built, because I build them myself, so I know that I'm embedding my values into every single algorithm I create and I am projecting my agenda onto those algorithms. Cathy O'Neil embedding algorithms agendas Evidence of harm is hard to come by. Cathy O'Neil evidence hard harm Every system using data separates humanity into winners and losers. Cathy O'Neil data loser humanity Because of my experience in Occupy, instead of asking the question, "Who will benefit from this system I'm implementing with the data?" I started to ask the question, "What will happen to the most vulnerable?" Or "Who is going to lose under this system? How will this affect the worst-off person?" Which is a very different question from "How does this improve certain people's lives?" Cathy O'Neil data doe people I don't think anybody's ever notified that they were sentenced to an extra two years because their recidivism score had been high, or notified that this beat cop happened to be in their neighborhood checking people's pockets for pot because of a predictive policing algorithm. That's just not how it works. Cathy O'Neil two years thinking Micro-targeting is the ability for a campaign to profile you, to know much more about you than you know about it, and then to choose exactly what to show you. Cathy O'Neil profile ability campaigns There might never be that moment when everyone says, "Oh my God, big data is awful." Cathy O'Neil data awful might The disconnect I was experiencing was that people hated Wall Street, but they loved tech. Cathy O'Neil wall hated people So much of our society as a whole is gearing us to maximize our salary or bonus. Basically, we just think in terms of money. Or, if not money, then, if you're in academia, it's prestige. It's a different kind of currency. And there's this unmeasured dimension of all jobs, which is whether it's improving the world. Cathy O'Neil bonus jobs thinking I would argue that one of the major problems with our blind trust in algorithms is that we can propagate discriminatory patterns without acknowledging any kind of intent. Cathy O'Neil algorithms patterns arguing The Facebook algorithm designers chose to let us see what our friends are talking about. They chose to show us, in some sense, more of the same. And that is the design decision that they could have decided differently. They could have said, "We're going to show you stuff that you've probably never seen before." I think they probably optimized their algorithm to make the most amount of money, and that probably meant showing people stuff that they already sort of agreed with, or were more likely to agree with. Cathy O'Neil talking people thinking I think what's happened is that the general public has become much more aware of the destructive power of Wall Street. Cathy O'Neil streets wall thinking We don't let a car company just throw out a car and start driving it around without checking that the wheels are fastened on. We know that would result in death; but for some reason we have no hesitation at throwing out some algorithms untested and unmonitored even when they're making very important life-and-death decisions. Cathy O'Neil life-and-death car decision When people are not given an option by some secret scoring system, it's very hard to complain, so they often don't even know that they've been victimized. Cathy O'Neil secret complaining people There's less of a connection for a lot of people between the technical decisions we make and the ethical ramifications we are responsible for. Cathy O'Neil decisions-we-make connections people We've learned our lesson with finance because they made a huge goddamn explosion that almost shut down the world. But the thing I realized is that there might never be an explosion on the scale of the financial crisis happening with big data. Cathy O'Neil data might world
