Famous Quotes By Cathy O'Neil
Some two thousand stone-throwing protesters gathered in the street outside the school. They chanted, "We want fairness. There is no fairness if you don't let us cheat." It sounds like a joke, but they were absolutely serious. — Cathy O'Neil
From a mathematical point of view, however, trust is hard to quantify. That's a challenge for people building models. Sadly, it's far easier to keep counting arrests, to build models that assume we're birds of a feather and treat us as such. Innocent people surrounded by criminals get treated badly, and criminals surrounded by law-abiding public get a pass. And because of the strong correlation between poverty and reported crime, the poor continue to get caught up in the digital dragnets. The rest of us barely have to think about them. — Cathy O'Neil
Someone who takes the trouble to see her file at one of the many brokerages, for example, might see the home mortgage, a Verizon bill, and a $ 459 repair on the garage door. But she won't see that she's in a bucket of people designated as "Rural and Barely Making It,"or perhaps "Retiring on Empty. — Cathy O'Neil
these models are constructed not just from data but from the choices we make about which data to pay attention to - and which to leave out. Those choices are not just about logistics, profits, and efficiency. They are fundamentally moral. If we back away from them and treat mathematical models as a neutral and inevitable force, like the weather or the tides, we abdicate our responsibility. And the result, as we've seen, is WMDs that treat us like machine parts in the workplace, that blackball employees and feast on inequities. We must come together to police these WMDs, to tame and disarm them. My hope is that they'll be remembered, like the deadly coal mines of a century ago, as relics of the early days of this new revolution, before we learned how to bring fairness and accountability to the age of data. Math deserves much better than WMDs, and democracy does too. — Cathy O'Neil
To create a model, then, we make choices about what's important enough to include, simplifying the world into a toy version that can be easily understood and from which we can infer important facts and actions. We expect it to handle only one job and accept that it will occasionally act like a clueless machine, one with enormous blind spots. — Cathy O'Neil
By the end of the meeting, one conscientious human being had cleared up the confusion generated by web-crawling data-gathering programs. The housing authority knew which Catherine Taylor it was dealing with. The question we're left with is this: How many Wanda Taylors are out there clearing up false identities and other errors in our data? The answer: not nearly enough. Humans in the data economy are outliers and throwbacks. — Cathy O'Neil
Thanks in part to the resulting high score on the evaluation, he gets a longer sentence, locking him away for more years in a prison where he's surrounded by fellow criminals - which raises the likelihood that he'll return to prison. He is finally released into the same poor neighborhood, this time with a criminal record, which makes it that much harder to find a job. If he commits another crime, the recidivism model can claim another success. But in fact the model itself contributes to a toxic cycle and helps to sustain it. That's a signature quality of a WMD. — Cathy O'Neil
This is a point I'll be returning to in future chapters: we've seen time and again that mathematical models can sift through data to locate people who are likely to face great challenges, whether from crime, poverty, or education. It's up to society whether to use that intelligence to reject and punish them - or to reach out to them with the resources they need. — Cathy O'Neil
Big Data processes codify the past. They do not invent the future. Doing that requires moral imagination, and that's something only humans can provide. We have to explicitly embed better values into our algorithms, creating Big Data models that follow our ethical lead. Sometimes that will mean putting fairness ahead of profit. — Cathy O'Neil
The privileged, we'll see time and again, are processed more by people, the masses by machines. — Cathy O'Neil
This creates a pernicious feedback loop. The policing itself spawns new data, which justifies more policing. And our prisons fill up with hundreds of thousands of people found guilty of victimless crimes. Most of them come from impoverished neighborhoods, and most are black or Hispanic. So even if a model is color blind, the result of it is anything but. In our largely segregated cities, geography is a highly effective proxy for race. — Cathy O'Neil
In WMDs, many poisonous assumptions are camouflaged by math and go largely untested and unquestioned. — Cathy O'Neil
The result is that we criminalize poverty, believing all the while that our tools are not only scientific but fair. — Cathy O'Neil
This is unjust. The questionnaire includes circumstances of a criminal's birth and upbringing, including his or her family, neighborhood, and friends. These details should not be relevant to a criminal case or to the sentencing. Indeed, if a prosecutor attempted to tar a defendant by mentioning his brother's criminal record or the high crime rate in his neighborhood, a decent defense attorney would roar, "Objection, Your Honor!" And a serious judge would sustain it. This is the basis of our legal system. We are judged by what we do, not by who we are. And although we don't know the exact weights that are attached to these parts of the test, any weight above zero is unreasonable. — Cathy O'Neil
My love for math eventually became a passion. I went to math camp when I was fourteen and came home clutching a Rubik's Cube to my chest. Math provided a neat refuge from the messiness of the real world. It marched forward, its field of knowledge expanding relentlessly, proof by proof. And — Cathy O'Neil
Baseball also has statistical rigor. Its gurus have an immense data set at hand, almost all of it directly related to the performance of players in the game. Moreover, their data is highly relevant to the outcomes they are trying to predict. This may sound obvious, but as we'll see throughout this book, the folks building WMDs routinely lack data for the behaviors they're most interested in. So they substitute stand-in data, or proxies. They draw statistical correlations between a person's zip code or language patterns and her potential to pay back a loan or handle a job. These correlations are discriminatory, and some of them are illegal. — Cathy O'Neil
I have no reason to believe that the social scientists at Facebook are actively gaming the political system. Most of them are serious academics carrying out research on a platform that they could only have dreamed about two decades ago. But what they have demonstrated is Facebook's enormous power to affect what we learn, how we feel, and whether we vote. Its platform is massive, powerful, and opaque. The algorithms are hidden from us, and we see only the results of the experiments researchers choose to publish. — Cathy O'Neil
However, when you create a model from proxies, it is far simpler for people to game it. This is because proxies are easier to manipulate than the complicated reality they represent. — Cathy O'Neil
Simpson's Paradox: when a whole body of data displays one trend, yet when broken into subgroups, the opposite trend comes into view for each of those subgroups. — Cathy O'Neil
The government regulates them, or chooses not to, approves or blocks their mergers and acquisitions, and sets their tax policies (often turning a blind eye to the billions parked in offshore tax havens). This is why tech companies, like the rest of corporate America, inundate Washington with lobbyists and quietly pour hundreds of millions of dollars in contributions into the political system. Now they're gaining the wherewithal to fine-tune our political behavior - and with it the shape of American government - just by tweaking their algorithms. — Cathy O'Neil
Racism, at the individual level, can be seen as a predictive model whirring away in billions of human minds around the world. It is built from faulty, incomplete, or generalized data. Whether it comes from experience or hearsay, the data indicates that certain types of people have behaved badly. That generates a binary prediction that all people of that race will behave that same way. Needless to say, racists don't spend a lot of time hunting down reliable data to train their twisted models. And once their model morphs into a belief, it becomes hardwired. It generates poisonous assumptions, yet rarely tests them, settling instead for data that seems to confirm and fortify them. Consequently, racism is the most slovenly of predictive models. It is powered by haphazard data gathering and spurious correlations, reinforced by institutional inequities, and polluted by confirmation bias. — Cathy O'Neil
The math-powered applications powering the data economy were based on choices made by fallible human beings. Some of these choices were no doubt made with the best intentions. Nevertheless, many of these models encoded human prejudice, misunderstanding, and bias into the software systems that increasingly managed our lives. Like gods, these mathematical models were opaque, their workings invisible to all but the highest priests in their domain: mathematicians and computer scientists. Their verdicts, even when wrong or harmful, were beyond dispute or appeal. And they tended to punish the poor and the oppressed in our society, while making the rich richer. — Cathy O'Neil

At the federal level, this problem could be greatly alleviated by abolishing the Electoral College system. It's the winner-take-all mathematics from state to state that delivers so much power to a relative handful of voters. It's as if in politics, as in economics, we have a privileged 1 percent. And the money from the financial 1 percent underwrites the microtargeting to secure the votes of the political 1 percent. Without the Electoral College, by contrast, every vote would be worth exactly the same. That would be a step toward democracy. — Cathy O'Neil
There's a paradox here. If we return one last time to that '50s-era banker, we see that his mind was occupied with human distortions - desires, prejudice, distrust of outsiders. To carry out the job more fairly and efficiently, he and the rest of his industry handed the work over to an algorithm. Sixty years later, the world is dominated by automatic systems chomping away on our error-ridden dossiers. They urgently require the context, common sense, and fairness that only humans can provide. However, if we leave this issue to the marketplace, which prizes efficiency, growth, and cash flow (while tolerating a certain degree of errors), meddling humans will be instructed to stand clear of the machinery. — Cathy O'Neil
Here we see that models, despite their reputation for impartiality, reflect goals and ideology. When I removed the possibility of eating Pop-Tarts at every meal, I was imposing my ideology on the meals model. It's something we do without a second thought. Our own values and desires influence our choices, from the data we choose to collect to the questions we ask. Models are opinions embedded in mathematics. — Cathy O'Neil
In a system in which cheating is the norm, following the rules amounts to a handicap. — Cathy O'Neil
The human victims of WMDs, we'll see time and again, are held to a far higher standard of evidence than the algorithms themselves. — Cathy O'Neil
I was forced to confront the ugly truth: people had deliberately wielded formulas to impress rather than clarify. — Cathy O'Neil
Just imagine if police enforced their zero-tolerance strategy in finance. They would arrest people for even the slightest infraction, whether it was chiseling investors on 401ks, providing misleading guidance, or committing petty frauds. Perhaps SWAT teams would descend on Greenwich, Connecticut. They'd go undercover in the taverns around Chicago's Mercantile Exchange. — Cathy O'Neil
Opaque and invisible models are the rule, and clear ones very much the exception. We're modeled as shoppers and couch potatoes, as patients and loan applicants, and very little of this do we see - even in applications we happily sign up for. Even when such models behave themselves, opacity can lead to a feeling of unfairness. — Cathy O'Neil
The trouble is that profits end up serving as a stand-in, or proxy, for truth. — Cathy O'Neil
