The era of blind faith in big data must end | Cathy O'Neil

Algorithms decide who gets a loan, who gets a job interview, who gets insurance and much more -- but they don't automatically make things fair. Mathematician and data scientist Cathy O'Neil coined a term for algorithms that are secret, important and harmful: "weapons of math destruction." Learn more about the hidden agendas behind the formulas.

5:51 "Algorithms don't make things fair... They repeat our past practices, our patterns. They automate the status quo. That would be great if we had a perfect world, but we don't." The perfect summary of the talk

[@coolbuddyshivam]

That's bullshit. There was an experiment with AlphaGo. The AI was set to compete with itself and it started generating new patterns after sometime. Her Arguments are all over the place. While Black Box algorithms should be banned but algorithmic biases are removed from AI after sometime automatically as it learns more datasets.

[@edawg792]

@@coolbuddyshivam I don't think you understand the kinds of algorithms she's talking about. AlphaGo is not remotely the same thing and you can not generalize patterns you observe in that very limited use case to algorithms in general.

[@galacticthreat1236]

I agree, if algorithms are just echos (pun-intended) of how we think, how does that represent the maker or user of it?

Her message is, as she said, "a blind faith towards the algorithm only sustains the status quo". This is not promoting any feminist or sjw ideas, it's an inconvenient truth that we should wake up to.

I worked as a graduate math teaching assistant at a very ethnically diverse university. I am not proud of it but I should admit that came to the US with an unfounded idea that some ethnic groups are not as good at math as other groups. However, what I found out through firsthand experience was that I was very wrong. I only find one thing that is correlated with an increment in math proficiency that is how much you are willing to try to master the subject. It is the most valuable lesson for me as a potential math teacher. And I am also glad for myself that I was able to be open and humble, and didn't perpetuate my unfounded idea through my mental algorithm to differentiate my students.

[@jhonshephard921]

there is also the issue of who is enrolling in STEM classes and the cost barrier to entry. Before I started spending my own money on the stuff I had been using to for both school and personal projects, I didn't know it was that expensive. Right down to the gaming laptop I was using vs some crappy dell ones other students used(and yes some did have a desktop at home or in a dorm). Since we know there is a historical economic gap among races in the US dating back to stuff like the Tulsa massacre by the KKK, we should know why there are fewer black students in Computer Science with us. And I admit I was racist because I didn't like that those people weren't garbing the opportunities offered in this field and joining me in class.

[@thatgui88]

So you basically admit you had a bias against certain races? Thank you for confirming that, I'll keep an eye out for racist teachers

[@mnaftw]

I work with big data and the exact same algorithms she's talking about - and she's right. This isnt perfect data we work with and the code isnt made by divine objective superhumans - its just us - a team of overworked underpaid data scientists who are all flawed human beings and honestly, the kinds of ways you are pressured to simplify or fix code at the last moment, you don't always have the time, the computing power or the straight up permission of higher ups to do the job 100% perfectly every time. Data can be a good tool, but it's as imperfect as anything out there. Maths and statistics arent gods, they are developed by humans and are less perfect than you might think. Also, maths isnt objective or subjective - it isnt a complex living mind, and we are far from making it one. We cant even agree on what that mind should behave like, let alone how to make it. So just, trust big data as much as you trust any salesman, for example.

[@admagnificat]

Thank you. As someone who works in a very human field where so-called "Value Added Measures" (VAM) are used to rate the vast majority of employees, I can corroborate that this practice can lead to some very, very unexpected and very, very unjust outcomes. I think that people are starting to realize this now, but I'm not sure how ratings will be handled as we move forward -- especially when the rating systems are often encoded into state law (which means that they can be very hard to change, and can stick around long after their fairness has been called into question).

[@MrGiovaneGuerreiro]

I don't take her message as "we cannot trust algorithms", but as an alert to the risks of someone not using them properly.

[@johannesstandoft760]

Her point is that you should look at statistics with the same skepticism and critisism as you whould do news or anything else. Being aware that statistics can be manipulated or even be unintentionally biased because of how data was collected is an important critical thinking skill.

[@thealayaseverus]

From the past. They are not made to predict the future, they are made to highligh peaks and lows and trends. And nobody can make a sober decision based on that =/ Not even the algorithm

[@Wombat7777777]

algorithms use statistics or data in general to predict stuff. Statistics and data are just as biased as algorithms a problem which stems from their creators, us.

[@summertime69]

Giovane Guerreiro but that's it, isn't It? If someone uses them wrong. Algorithms are a science and if you use that science poorly, you get bad results. Math and science are tools that can be used for ill or for good. She srates that all these algorithms are bad and math is scary. Weapons of math destruction? Bah!. She said bad people use neutral tools and we should stop using the tools because she can't think of a time when algorithms are good.

[@nileab5717]

Just to remind you that she holds a PhD in math from Harvard and she is not biased or anti science at all. She might sound like feminists and post modernists but don't forget she is talking about fairness. I'm not mathematician but I know there is always a level of subjectivity in modeling/algorithm and it comes from variables used or omitted, methods used vs alternative methods, etc.

[@torvaderon]

When it comes to reality you should consult a physicist not a mathematician.

[@SummaPlusANumberGrrr]

Sure, but she's just very bad at forming a strong and consistent argument. Therefore it's not clear what her message is, which is surprising since the "TED way of talking" is to have one very clearly shared message. In this talk, there's tons of half-thoughts and half-examples, and therefore her "big conclusions" appear on wobbly ground.

[@shooshydooshy]

Wow! I'll admit, when I saw the thumbnail I was afraid this would be some sort of weird speech from the deep depths of tumblr. Then I listened, no bias in between and... she's right! Machines work like they're told to work. And who tells a machine how to work? Humans. So if that human doesn't think about their own prejudices, or about past prejudices as well... the machine won't, either. And the algorithm that human made will act accordingly to how it was told to act.

I once worked for a company taking calls from customers. They used to judge the customer's satisfaction by a follow up call to the customer and an automated survey. Sure customers who were angry were more likely to take that survey but you were hearing it from them. Then they decided to turn this over to an algorithm that listened to the calls and scored the worker based on that. It was utter garbage, demonstratively inaccurate. A customer could profusely thank you for your help at the end of the call and this junk code would say they had a bad experience. We employees and local management had no access to the algorithm, very little data on what it was actually looking for, we were just supposed to trust the process. What it came up with factored into our performance scores and ultimately our raises. It wasn't long before I left.

[@KateLate____]

There's an assumption here that a single algorithm is being used, and that it's simple enough to be written on a piece of paper. Algorithms are very complex now, and cannot be evaluated by "eyeballing" them. Whoever developed them would need to disclose their full data set and their approaches. Maybe this should be done. But it's not as simple as sending an email.

[@docskate4312]

The era of blind faith in big data should end. But it won't. The stuff this speaker spoke about is the key to making big money in our days, where making ends meet has become more and more difficult. Algorithms are the tools to extract more money out of people and will always be shaped for this purpose. All aspects of the matter, socially and also politically can be broken down to this one goal. Money. If we don't change - why not picture our species ending up in some skynet-like crap? Control over data is an ongoing war not just since yesterday. Here in Germany I sometimes get the feeling that we have already lost this fight by simply obeying and just continue walking our path, consuming all offers and giving away all of our personal data thankfully. And yes - I use the internet, but hate social media.

Within 3 months after being on Obama care our coverage increased 68% for no reason. We couldn't afford to stay on this coverage so she went back to work in the private sector. This left us with a gapping hole with or management. After running the business by myself for 18 month I ran the business into the ground and my health started to suffer.

[@mikehart4172]

While some of the terminology and presentation of Cathy's argument were polarizing for many viewers (explained by the like/dislikes ratio). Her point about how data collection and interpretation can be skewed is a valid point and needs to addressed. While I cannot say I am a good source to rely on, I am an informed person who understands the validity of correcting skewed data. I support her view on having more oversight over the input-output of these algorithms since many companies will not change them unless someone can prove that it is losing them money or force them to correct it. As for the presentation itself Ms. O'Neil should have went for a more objective/ more informative title to increase viewer-ship and prevent political/social bias from factoring. This problem also arose from her dress and terminology causing viewers to ignore her point which could have been remedied by her having more xp talking publicly (but she is a scientist not a speaker) so that she could properly trim and present her point without appearing nervous or bias.

9:28 Most people confuse US racism and thoughts of supremacy to mean Neo-nazism; most of the time it doesn't, as that is only the extreme end of the spectrum. The concepts refer to outcomes based on widespread attributions of both conscious and primarily unconscious propensities for treatment based on visual cues relative to someone's background. That is either a sense of someone deserving full services, being given unearned trust, and being shown respectful, appreciative, friendly interaction OR contrarily any thoughts of unworthiness, seeking excessive control over the behavior of someone (mistrust), corner cutting when servicing someone, and/or dismissal of someone based on traditional visual stereotypes.

This is excellent. Many of the crappy decisions I see everyday in buisness are based on terrible data. Not only that people that depend on them use them are basically lazy. Logic is about laziness. Using a system instead of actually thinking. We didn't get this far using data or algorithms. We used our collective and individual brains and experience. People are lazy thinkers. They prefer systems because they don't want to begin to actually think. Logic is about excluding data. Not including data or information, leads to all the really poor decision making around me. It is also about the past, not present , not the future. The past. And it is a terrible narrowing of human thought.

If we input garbage the computer outputs garbage. But that is why smart people tackle this problem. If society reaches a point when it depends to much on stupid algorithms lawmakers should intervene but in this scenario we likely have stupider lawmakers as they are a part of the society that allowed those stupid algorithms to happen. So we need to be careful but if it happens we ar screwed.

[@EANTYcrown]

Being fair the point she is making is not wrong is just, in my opinion, poorly expressed due to its deliberate political agenda wich clouds a solid argument, Badly designed algorithms will lead us to bad results (not the most insightful idea but a logical one nonetheless). As a result i think that a more useful conclusion is that we must all work together in order to make sure that the algorithms we use are properly designed, so we can manage to make them not repeat the mistakes of our past, but rather to improve in the future, defining with greater accuracy what we deem as success and improving our methods, as a result eventually achieve a methodology that decides based only on the expected results and capabilities of people, instead of who they are.

[@Wegnerrobert2]

I dont really see her point... She is effectively stating that machine learning algorithms/big data usage is being badly implemented. An algorithm should only be used knowing what it can do and what it cant do, how it was trained and what it didnt see during training. But this seems like a very basic and obvious concept to me. In the cases where it was violated I'm dure the people that did it would have done a better job if it was just that easy. But even if the algorithm wasnt "perfect" it probably returned better results than previous methods. It's not like human judgement isnt frequently biased too, so thinking by using algorthms we can expect objectivity is naive but that's ok, everything is a progress and the quality of big data processing will only increase. This talk is way to aggressive for my taste (weapons of math destruction cmon)

[@NizarElZarif]

The problem is not the learning algorithm, SVM, neural network, HMM and others are meant to be meant to give the highest accuracy classification or prediction. it is based on the data, generally, the larger the dataset the more accurate the result would be. however, the problem might be how the data was gathered. These Machine learning algorithm aren't meant to replace human, but to make their work easier. for example a algorithm can reduce the time of doctor to give a diagnosis. or help facilitate the amount of interset a bank or an insurance might have. i never heared someone was fired because an algorithm told them so. so the main point is how we gathere the data rather the Machine leanrning algorithm selfselves. and generally, the most popular datasets are clear on how they gather the information

This has aged unexpectedly well

The algorithms she is talking about are designed to do one thing only. Look at correlations. Ah I see you have has two car wrecks. Statistically speaking people that have had two car wrecks are more likely to have a third, so your insurance goes up. Algorithms look at one thing and see if there is a correlation in another thing. It isn't causation but it is significant. Everyone uses these. Stereotypes are a great example, they may not represent everyone, but they go represent a fair portion of that population. Just another algorithm. The hard part is to use enough data to get enough correlations and make it more accurate. Compare 2 people. One is black, another is Asian. Who is more likely to succeed. statistics would probably say the Asian if you only use that data. Now add more data. The black went to college and the Asian didn't. Now the black has a statistically higher chance of succeeding. It is all about the data, usually the more relevant data, the better.

Can we just forget political Ideologies for now and use the comments system properly instead of fighting like arrogant children?

[@EagleZtoTheGrave]

THE GREY MAN NOPE... lol

[@imskiller99]

I would like to refer you to 12:52. Also youtube comments tend to be cancer.

[@NathanGatten]

THE GREY MAN the KZbin comment system is pretty much literally made to influence people toward arguing with eachother. Unfortunately the negativity in the comments is simply a by-product of the faultiness of KZbin's own comment system.

[@brendarua01]

What political ideology do you see here?

[@brownpepe806]

How do you "properly" use a comment section? You don't

[@imapollard7857]

She's right.

I saw the caption and picture and immediately knew this will be a fun ride.

[@tronerman]

No

[@JanPospisilArt]

0:38 That's not how you use "begs the question". That's not what it means. Stop.

Isn't it a great thing then that Fox News doesn't use a learning algorithm for the hiring process

[@kashatnick]

And the problem is that she complains about over simplified metrics being an incomplete model of the world, yet her presuppositions are based on the very same over simplification, things like the wage gap are based entirely on crude algorithms comparing apples to oranges. On policing, the crime stats are simply damning once you look at them, simply the prevalence of suspects willing to shoot back at the police at rates several times more than other groups will skew the data in a way I'm sure she wouldn't accept. She's right in a way, but I'm sure her ilk simply wish to skew the data to paint an incomplete picture in the way they prefer.

Big data says not to match your hair with your sweater with your shirt....

[@Wanderers-Bulgaria]

Q: - Can it be created an algorithm based on a near perfect past? Abstract thought: - If algorithms repeat past practice, past patterns, then to me the universe is a one source of algorithm. Repeated events on regular basis (super volcano eruption, asteroid impact, mass extinction) and the universal algorithm presumes what will be success, and sends us an asteroid. For this algorithm success would be: every once and awhile, mass extinction. That is its success. Kind of sci-fi thoughts, or perhaps the matrix 🤔 😎 👀 😉 😳 😏

BRAVOOOO!!!!!!!!! I cannot cheer enough this overdue discussion!

[@sikaychung8140]

OMG, nice to meet u here Vera~

[@skoky76]

Algorithmology studies?

[@ruizhenmai1194]

Algorithms are often based on past statistics. But humans are not

[@rhysmcgreal8786]

No I loved what you say. But saying that top companies use this is so so wrong...

[@rhysmcgreal8786]

I can be truthful in this modern age. I am biasedly discriminated because I am a male. My problem is we shouldn't look at genda. I am all for Equal rights but equal of opportunity. Not outcome x
