    Hi Cathy! Sara Billey just publicized your blog at the Nebraska Conference for Undergraduate Women in Mathematics. I didn’t know about it before but I’m looking forward to getting caught up on it. I still have your PhD thesis sitting on my bookshelf by the way….

    Hi, Cathy,
    Great blog! I’m a Comm. College math teacher in suburban Chicago, typical bald white male, and your take on issues of women in math fully dovetails with my own experience. I thought I’d just give you a couple additional perspectives, if you’re interested.

    In my classes, I have students write a “math autobiography” at the start, telling me their past experiences in math. The single most common trope is that of women saying “I loved math up until ___ grade”, with 5,6, or 7 most often in the blank, though sometimes up to 8 or 9, “when Mr. X, my new teacher, refused to answer our questions or help us, thought we were dumb, but passed us anyway.” Of course, the sequential nature of math means these students are now unable to understand or catch up in later grades, and rapidly come to hate math, with good reason. A single bad (usually male) teacher has much more effect in math than in, say, English or history. The real locus of effective educational change in this country in math and in all aspects of critical thinking has to be at the K-12 level, where intellectual skills are as likely to be dulled as honed by allowing opportunity for real creativity and enthusiasm.

    Secondly, you are rightly suspect of the “nature” side of the nature vs. nurture argument–but, in my opinion, not strongly enough. Evolutionary biology is a side-interest of mine, and particulalry the political misuses of bad science involving “biological superiority” claims. I first got into this several decades ago via the book “The IQ Controversy”, which I highly recommend. It showed that claims that minorities (largely blacks) had hereditarily lower IQ’s were both empirically false (unsubstantiated by properly controlled scientific evidence, or, worse, involving outright fraud) and conceptually incoherent. Ever since, I carefully follow similar claims about other inherent biological superiority, including, of course, that of men in math, to see if the same critique applies–and it simply always does. You could be quite confident of being right in simply saying that any such claims are almost certain to involve data that have not been adequately controlled for, and to never give them any credence in advance. Your point about the null hypothesis is thus extremely apt–but, frankly, there is virtually no real (adequately controlled) evidence at all even challenging the null hypothesis.

    The main reason for this is simply that culture is a far more pervasive and uncontrollable influence than virtually any scientists allow. Even a two-year old has had over ten-thousand hours of absorbing cultural data non-stop every waking moment–for Summers to claim his kids demonstrate any of his claims just shows that he doesn’t understand controlled scientific experiments. It is virtually impossible to do an adequately controlled scientific experiment in any realm that involves culture in any way–which is every important realm!

    In The IQ Controversy, Noam Chomsky makes a different point, which is worth considering as well–it wouldn’t matter if math (though he refers to IQ) skills WERE completely hereditary or biological, if we established a just society. Swimming “skills” are fairly biological, but no one finds it problematic–because society does not use swimming ability as an unjust criteria to differentially reward or oppress people. Average group differentials in swimming ability lead to no general unhappiness, and don’t prevent any individual from deploying their particular skills as they wish–we need to establish the same sort of society regarding all intellectual skills. If fewer (or more!) women then display math skills, so what, even if they are biologically based, as long as all who have them can develop them to the extent they wish.

    Finally, your take on the collaborative nature of math is slowly becoming more common practice, at least in my classes. I let students do hands-on review problem sets before tests, and they can work together. Women have always been more likely to do so in pairs and small groups, for obviousl cultural reasons, but nowadays my male students take advantage of that almost as much, as opposed to “lone wolf” types struggling through it themselves. At least, this is true up through 1st Semester Calculus, which has lots of pharmacy, pre-med, and other non-math, non-engineering students in it who will never take Calc 2, and which is about 50-50 male/female. It’s true that Calc 2 reverts to more traditional form genderwise, but even there the trend is towards more women, and more males who work in collaborative fashion. It is still true there, though. that I occasionally have women who wish to work “alone”, not out of anti-social tendencies, but just because they really, really like the “challenge” and satisfaction of getting it on their own–a feeling I am extremly familiar with… 🙂

    At any rate, keep up the truly excellent work–your blog is now, along with NC and a few others, a highlight of my net surfing!

    • May 8, 2016 at 11:10 am

      While I generally agree with your comments, there is one fairly significant factual problem. Turns out, the Marine Corps DOES in fact use swimming skills as a selection criteria and for reasons no one fully understands, many minority groups underperform in quantitative metrics. I suggest juggling skills might make a good replacement in your argument.


      • Paul
        September 12, 2016 at 10:13 pm

        John, one likely reason minorities tend to underperform in swimming is that swimming is expensive. Poverty tends to be higher among minority groups. Affluent people can afford to pay swimming memberships. Poor people cannot, and therefore do not have the opportunity to practice swimming. Thus, I’d expect to see under representation of minorities at high levels of swimming competition, and that is what I observe. Further, I’d expect the same at all levels of achievement in swimming.

        Juggling, however, only requires a few balls and the ability to concentrate well. 🙂

    Just discovered your blog, Cathy, and love it.

    I note that you teach at a “math camp” in the summer. Even though one of my prior, brief “careers” was teaching 7th & 8th grade English, my real love is math. [I was a math major in college until “chased out” by disparaging comments about women in the field. This was the late 60s.]

    I’m currently assisting a 3rd grade teacher in our local school, in particular working with the slowest learners on mastering their “math facts.”

    Two questions for you: can you suggest books, materials, web sites, etc. that provide guidance to folks like me who are attempting to tutor in this area? Obviously I use the teacher’s materials, but I’m interested in what else might be out there.

    Second: I’ve always thought that someone should establish a Tutor For America program to recruit and train folks to work in public schools. I’m thinking about having folks tutor on a small scale [an hour or two per day/ a day or two per week], nothing like the larger commitment that’s required by TFA. I’m particularly mindful of this because of the larger number of folks who will be retiring and looking for some way to contribute.

    I would emphasize the “train” part of that equation, since I have a number of misgivings about Teach for America, the main one being their apparent belief that “we can just throw a bunch of ‘bright’ kids into the schools and they’ll provide more for the students than the current crop of ‘crappy’ teachers.”

    Anecdotally, a friend whose daughter is just getting her degree from Tulane in elementary education reported to me that the parishes around New Orleans have fired their “regular” teachers and brought in TFA people, because they can save so much money in doing so. Obviously no job there for this young person who desperately wants to teach.

    And, re the discussion re Harvard grads above, doubt that Harvard is pushing its folks to enter teaching as a “meaningful” career. [My MAT is from there.]

    I feel like I ran into a column or a blog post or article of some sort very recently written by a conservative, pos. a Repub congresswoman, about fed gov student loan help as the reason for higher admission costs. I only skimmed it, cause the vibe pissed me off since I thought she was advocating for no gov’t help for college tuition, but that was b4 I saw you piece on collage or even college debt.

    i would like to know if the OWS movement is gaining traction . as more skilled blue collar trades poeple find a common ground here ?

    You say we can reform banking, just as we did in the great depression. It seems to me every reform has to be reformed. How about if we just let it go wild? No government intervention whatever. Let it bleed. Let banks fail and investors get burned. Disband the SEC and Federal Reserve. Too Libertarian?

    I am oddly compelled to chime in another “Wow” after seeing the Frontline interview – oddly, because I don’t feel (dare I say it?) “smart enough” to even participate beyond lurking within your blogsphere!!!

    As one of those “people persons” who graduated from a fairly un-glam state college in CA with a fuzzy studies degree, landing work in corporate education, I had the opportunity to work with CapitalOne Financial between ’00-’02. I got my share of eye-rolling from better educated peers, but frankly I didn’t “get” what these smug, highly-recruited whizkids were actually DOING until years later.

    I’ve been intimidated by math all of my life, but adore mixing it up with intelligent, opinionated folks like those flocking to this site. The attraction/repulsion tickles me to no end and frankly, you simply rock it.

    You have a new follower in me. While I’m overwhelmingly challenged with much of the content, I certainly feel your intelligent and spiritual underpinnings and that comfort and inspires me.

    Hello Cathy,
    After listening to the extended video of your Frontline interview I knew your blog was going to be goldmine.
    A couple of years before the crash I resolved to get smart about the financial world, but at the end of my WSJ and The Financial Times subscriptions I realized my mental runway was not long enough for most of what was being discussed to land. Hopefully after reading everything posted on your blog I’ll be a bit smarter and be able to sort the wheat from the chaff. OWS has a 1/2 hour show on WBAI everyday. A show devoted to the work of your working group would give the program a nice shot in the arm. I’m going to recommend that the Program Director contact you and you can take it from there. As understanding increases, opportunities for exploitation diminish. The work you are doing is proof that generosity is truly the mother of all virtues.

    Meant to be my reply to the above, sorry for my indefinitiveness:

    Umm, that would be very much like once again allowing any “patent” medicine back on the market, no matter how poisonous, then letting “the market” decide which ones should be outlawed after some level of death is reached. Only with financial chaos, the level of deaths may be far higher!

Do you have any suggestions for going about that or sources that might talk about it? Thank you very much!

    Hello Cathy: I teach at a small liberal arts college (~1700 students) with a successful and (relatively) sizable mathematical sciences department (my department has ~7-8% of all students). This includes majors in mathematics (including ed.), cs, and actuarial science. Most of our majors are in actuarial science, because a recently deceased faculty member spent decades building a quality program with word-of-mouth eventually bringing us more and better students. All of our actuarial students must pass exams before graduation and 100% of our graduates complete paid internships and land actuarial jobs immediately out of college.

    I am a new faculty member, and I dream of continuing this growth and success. I am intrigued by data science — you have already posted about things someone should know to be a data scientist and about your indecision about whether there should be such programs. If you think it worthwhile, I would love a refinement of these ideas in a post about 1) some sort of clarification of the definition of “data science”, and how it is different, if at all, from business analytics, etc., or 2) what you think an undergraduate degree should entail at a minimum. I would hope that mandatory internship(s) would allow students to be introduced to actual big useful data, but perhaps companies are too concerned with security to let a summer intern have at it? It sounds like there are too many skills required of a seasoned professional to fit into a reasonably-sized major. But I wonder if there is some underlying list of fundamentals you can think of that could constitute a feasible and coherent program that would lead to success in a graduate program or immediate work in data science. Also, is there or do you think there will be, like in actuarial science, some credentialing program that will allow people a structured path to continue down while developing more of the necessary skills after graduation?

    Thank you for your consideration.

    P.S. I’m also a number theorist. Go number theory!

    Dear Cathy,

    I recently saw your interview on Frontline. I was very much impressed with your analysis and with your oh-so-true comments. I am also sympathetic to your desire to ‘clarify’ – to break things down and demystifiy all the jagon and idle talk that passes itself off as serious yet which is, frankly, evidence of poor thinking – if any at all. And this poor thinking that is masked in seriousness is evidence, moreover, that the culture is in a dire place. Much more to say, but, for the meantime, bravo.

    Hi Cathy. I’m a fellow Karaoke fan who also discovered you on Frontline. It goes without saying that TED is flawed, since you would be a major TED star if it wasn’t.

    I’d be interested in your reaction to two TED talks:

    One talk argues for greater focus on statistics in the teaching of pre-college math. I must say I’m appalled at how few people have the most basic understanding of statistics.

    The other talk is about the dangers of hyper-specialization in the liberal arts. Lack of hyper-specialization strikes me as one of your strengths: For example, you seem able to hold mathematical AND ethical considerations in your mind at the same time. I believe this has been outlawed in several states.

    I hope I get to thoughts on these topics. Until then, have fun at math camp.

    Cathy, and others on this blog articulating your passions for American economic discourse, you might be very interested in attending a program taking place tomorrow Tuesday 7/24 at 6:30p at Museum of the City of New York.

    Cornell University professor Louis Hyman is author of the new book, “Borrow: The American Way of Debt,” which examines how the rise of consumer borrowing in the 1920s, just before the Great Depression, altered our culture and economy. Tomorrow evening, Professor Hyman will explore New York’s role as a center of this financial innovation, which allowed lending to grow more and more profitable, but in turn, displaced funds available for business borrowing—a reconfiguration that set our economy on an unsustainable course. He will offer an historical perspective on the temptation to live beyond one’s means; and offer suggestions for change moving forward. Reception to follow.
    Reservations required. $6 Museum members; $8 students/seniors; $12 adults.

    Museum of the City of New York is located at 1220 Fifth Avenue, corner of 103rd St, in Manhattan.

    The connection between Wall Street, academia and mathematics is complex. One element of that connection may well be a foundational error in mathematics (that has not been rooted out by academia, so you could say that it is supported by academia), which could possibly bring the most natural explanation of some of Wall Street’s chief idiosyncrasies. The foundational error is detailed in my preprint introduced at http://limitstomaths.com . The connection may simply be that an error in foundation may permit errors (including biases, and high cartel like behaviors) everywhere else to manifest more straightforwardly. The intriguing message for the future, however, is that all systems involving the globalization of a coherent pressure — just like the boiling of water, leading to the infinite phase transition from liquid to gas phase in a finite global volume — have, evidently, a characteristic of self-transformation.

    There is definitely something here, and since this seems right up your alley at the intersection of mathematics and the real world, I would love to have you investigate and comment! : )

This is as “hard math” as you can get, and two women – is it politically correct to say “babe” ? – laureate.

    Hi Cathy…I just got done reading your article “Economist don’t understand the Financial System” an I thoroughly enjoyed it. My name is Liam McDermott and I used to be an institutional Eurodollar and Energy broker. I also dealt in market data. I have been off the street for a number of years, but I have recently written an original economic theory based on placing serial numbers onto electronic dollars. I have been having difficulty getting it out there because of my lack of academic credentials. You seem to be someone who is more open minded, so I wanted to share it with you to see what you think. If you enjoy it and would like to contact me my email is liamalan@gmail.com. Thx!
    Serial Number Transparency
    If American’s vote to force Congress to assign individual serial numbers to electronic dollars, the global economy will undergo a renaissance.
    All private and business bank accounts retain the exact same amount of cash, but by placing individual serial numbers on these electronic dollars they become “real” in the same sense that paper ones are. Trillions of “derivative dollars” currently present on large investment banks Off Balance Sheet books become worthless because they are derived and by definition, not real. The remaining pool of money is clean, reliable and transparent. Since this new pool of money is much smaller, the value of each individual dollar is greatly increased.
    In order to protect the purity of this new pool of money, the Federal Reserve will no longer be able to arbitrarily create money. The majority of Americans would be outraged to learn that the Federal Reserve Bank is actually a private corporation, owned and operated by twenty one, MOSTLY FOREIGN banks. These banks currently use the Fed to create cash for themselves while paying interest to themselves. The Fed operates cloaked in secrecy, with total autonomy, creating money with no oversight from the Federal Government. Serial numbers would make the 7.7 trillion dollars the Fed fabricated out of thin air for their 2008 bailout disappear, restoring the value of the dollar to its pre-crash levels. Serial numbers wrest control of the American Dollar from the clutches of unregulated foreigners and places it back in the hands of the American people whom it is supposed to represent.
    When banks need more cash they would now petition Congress. Bankers would present their case for a cash auction and it would be put to a vote. Banks would now pay interest to the government for their cash, lessening the burden of the American Taxpayer. The economy will be well served by having a static amount of cash to represent the goods and services it has the ability to produce. As the capacity of the economy grows, more money would be injected into the system by Congress reflecting an increase.
    Banks’ secret electronic trading platforms now would be replaced by open outcry trading pits, effectively ending backroom market manipulation. A system of three main pits where brokers openly trade equities, debt and commodities would be outfitted with cameras broadcasting real time, worldwide for free. This will ensure all market participants equal access to information. Imagine the world’s greatest reality show that everyone can bet on from home.
    Politician’s campaign dollars serial numbers will make all of their allegiances instantly visible. Regardless of where on the political spectrum they lie, every American has a right to know what his candidate is going to do once elected. A politician’s true agenda is shaped in the interests of their contributors, not their constituency. Democracy is muddled into a sham when it lacks this transparency.
    Serial numbers will cripple the finances of terrorist and criminal organizations by stopping electronic black money flows. Any illegal activity would become an all cash business. While this would not end crime, it would destroy enterprise criminal corruption, while at the same time making money real for honest people who really work for their money.
    This new form of naked capitalism will insure pure liquidity through pure transparency. Regulation will come about organically, based on the simple fact that everyone can see what everyone else is doing. Serial numbers enable the American economy to work the way it was intended, honestly, transparently and with equal access to information.
    The American Dollar is based on accountability whether it is on a computer server, or printed on a bill in your wallet. No institution should have the power to create, manipulate and devalue the dollar bill for which millions of people have put in an honest day’s work. A true American, capitalist democracy demands its financial, political and criminal framework to be illuminated by serial numbers.

      Liam, your ideas sound sound enough; however, if as you state the system is perhaps rigged to manipulate macro monetary policy, then in a practical, tangible view it may be highly implausible that the system will ever voluntarily stop doing it without a violent and protracted revolution.

      What’s your ideas on this issue?

    The beautiful thin about America is that it is a democracy. We all have the power to change the system in non-violent means. I am currently making a documentary on my theory and money creation. It is my hope that once people are made aware of the situation, we will be able to garner the political will to change the system. I used to work in institutional trading on Wall Street. I have pitched this idea to many people over there and gotten an overwhelmingly positive response. If I can convince the people on Main street to agree with me as well, all we have to do is vote people into power that agree with our position.
    Take care.

    On Being a Data Skeptic

    Before reading this book, I would have classified myself as a skeptical cynic on the subject of data. But now I think I am a data heretic. Although this book points out important factors to consider when working with data, if taken in its entirety the recommendations could be summed up in one conclusion “trust no data”. Considering the fact that data is not facts and adding to this the non-transparent manipulations and assumptions we apply to data, it remains surprising that we can derive any semblance of reality from data.

    Data and data analysis is story telling. We tell stories with data. In my experiences most of the data story telling is fictional, something I refer to as “datatainment”. Much of what is being written about the subject of data such as big data and data science is a story and also fictional. It reminds me of the liar’s paradox; “this sentence is false”. What is the truth?

    The most important factor to consider when working with data is do you trust those who are presenting the story about the data. Are those involved in selecting and manipulating the data trustworthy? Look at the history of these people; their experiences and their motivations. Is the story they are telling with data trustworthy? Is it fiction or fact? Do they substantiate their arguments or are they bloviating. Are they transparent about what the data means, what assumptions were made and the way their models manipulate the data?

    Of course once you consider the factors outlined in the book and these factors you too may become a data heretic.

I initially did programming in Lotus Notes, which is basically extinct, although someone may yet discover a Lotus Notes programmer trapped in amber… I am hyperintrigued (I made that up) by Data Science, and am considering applying to a Data Science Boot Camp, although the one I have in mind charges $14,000.

    Do you have any opinions about the cost vs. benefit of such programs?

    Kind Regards,


    • July 19, 2017 at 11:25 pm

      $14,000 for a boot camp is a scam. For a bit more you might cover the costs of a masters degree at a decent university (excluding the fancy ones). Also, if you have Weapons of Math Destruction, check out page 64 talking about the four-day boot camp that costs $16,000.

    This has been a pet peeve of mind for a while. It just came back up because I’m in the process of purchasing a home, and my home insurance quotes have been all over the place. About 8 years ago I found a report about insurance scores written by an analyst at progressive insurance. The report admitted that the insurance scores, although they were good predictors of if someone would file a claim(not have an accident/there is a difference) that there was some overlap with the other factors ie if you lived in an area with high claims, maybe that area also has lower credit scores, so in many cases it is possible to get dinged twice. This is why I liked your statement about “price discrimination”, which is a marketing technique taught to me in school. Make no mistake these techniques are not so much to provide pricing relative to the risk (which is what is told to us consumers and why we go along), but as to create complex pricing strategies to maximize revenue. The more factors you come up with the more potential you have for revenue. The only way around this is to end the information asymmetry. We should have legislators mandate that insurers must share their “prime rate”; their best rate for each product so consumers can have a way to easily gauge weather they are ok with the extra risk premium they are being quoted. Just as there is a prime rate for bank loan rates. But this is where insurance companies want us, in the dark with little power.


  88. July 12, 2015 at 12:30 pm

    I like Slate Money panels, especially Cathy’s observations and questioning. Regarding the Occam Razor approach on technical glitches and complexity of software, empirical evidence suggests one more level of simplicity. Vandals are cutting the wires. Whatever their reasons, this is happening, really, I can attest.

    February 25 2015 Northern Arizona 5 hour outage

    and other attacks over the past year

    In the AZ attack, commerce and support services halted. Most Local cell and land calls did not go through. Banks locked their doors. 911 was flaky. The national rural Code Red emergency notification system could not send messages. An observer might find this outage an excellent test case on disruption and citizen reactions. Bad weather or an extended outage could have caused fatalities. It was scary.

    What was learned? A single company, CenturyLink, serves all Northern AZ. with no redundancy. Vandalism was easy enough in the desert. There are no citizen protection groups for this type of disruption versus, for example, wildfires. For me, personally, the local taxi drivers with their redundant dispatch services and demographic knowledge offer the most immediate and reliable information.

    We should all be asking about vulnerability of our physical infrastructure and share the answers.

Since 1988 my work in university is related to statistical packages and I often argue against the idea that software replace mathematical formation.

    Hi Cathy,

    I just finished Weapons of Math Destruction in two intense reading periods because of the compelling writing. I was especially fascinated with how prescient you were about the effects of social media on US elections as was clearly seen in the 2016 election. Facebook still needs to answer for it’s part in allowing all the Russian ads that favored Trump.

    I graduated with a math degree up here in Alberta Canada over ten years ago but haven’t really used it since I’ve been teaching English abroad mostly. I’m now considering getting into a master’s program at the University of Alberta in data science. However I’d like to work afterwards for either non profits that are trying to improve society or in the service of animal conservation in the world.

    If you have any recommendations or suggestions it would be greatly appreciated.

    Looking forward to your next book!

    I searched your site for references to IHME, and didn’t find any so I’m assuming this hasn’t crossed your radar yet. If I’m not mistake, his critique is right up your alley. This is a ‘machine learning’ type approach that eschews fundamentals of epidemiology and just uses a bunch of open-loop highly unreliable fitting tools. I won’t presume to explain this further, I’m sure you will come to your own (far more accurate) conclusions far more quickly than I could summarize it for you.

    I hope you find this relevant. Even if you don’t I think what you are doing is great. Keep fighting the good fight, sister!

      Oh the power of hindsight! Bahamas was COVID free by May of last year and rather than follow common sense and open up to other COVID free nations it took poor advice from “experts” and opened up to a US COVID rampage ! Stupid is as stupid does.

    Cathy , there was an article from Australia on a spike of indigenous children being taken into government care. It found was found later that the government department was using an off the shelf risk assessment algorithm from the US , and had little to do with conditions in Australia.

    Hey Cathy – I started listening to the audiobook version of “Weapons of Math Destruction” and it’s been really interesting so far. Not sure if you’re aware but your book is assigned reading for one of my classes at Georgia Tech – “CS-8803-O10 – AI, Ethics, and Society” https://omscs.gatech.edu/cs-8803-o10-ai-ethics-and-society

    As a side note – I found it funny that you were a quant on a futures team, I actually started a new software job recently at a big bank in the futures group, not as a quant though. Looking forward to listening to the rest of your book and learning from your unique perspective.

    Hello my name is Jeramie Huber. I’m from the Midwest and 33yrs of age. I have a background in Construction (Carpentry). I Love Mathematics, Physical Fitness, and Family.

    I have Multiple proofs for Mathematical Hypothesis. I beleive you would have interest in these after seeing your videos on Algorithms.

    I’m reaching out to you sense your familiar with the mathematical world. I could really use some help with making the mathematical world aware of these Proofs; It’s of use and doesn’t exist.

    Feel free to contact me by email or phone at: 219-781-4972

    If there are any other questions feel free to ask.

    Love, Respect, Peace and Patience.

    You are my superhero—–I wish (desperately) there was a way to excise Elumen and the idea that ‘measurement’ of SLOs (pushing a 70% attainment rate) is just a pernicious falsehood to my college administration—-but alas, like Rhee, they have attended some ‘conference’ where the ‘data scientists’ have created algorithms and packaged them in a nice box so as to ensure the information produced can be easily digested by folks who left the classroom YEARS ago (assuming they were ever in one, to begin with). Thanks, Cathy—-you have validated even my rudimentary statistical skills and reassured me that, in fact, I am not crazy and the inability of those in the “head shed” simply fail to recognize grade inflation will be the ‘hedge’ they will actually witness. Three years to retirement and counting——-

    You’re the smartest person in the room, especially related to CDS and many derivatives. I have a math problem. I created a formula for BTC cost to mine one, proof of work, and I consider this to be intrinsic value of one bitcoin. There is a huge flaw in the Bitcoin system. If the value intrinsic of BTC is based on the power of miners, the Compute, then what if the market price drops in tandem with instrisic value based on people stopping mining it? Is there a downward spiral crash to near zero dollars? I’d like the opinion of a doctorate in math. Thanks!!! Jim

    Hi Cathy. I just wanted to let you know that I really appreciate you being out there and starting conversations about Shame. I’m a psychologist who’s not intending to write a book, but if I were to, I would want to do it on shame, because I feel that it’s the most psychologically damaging thing going right now. Just know that your message is appreciated.

    We are trying to replicate flawed “intelligent” systems namely us. The machines are performing as planned.
    What is required is an ontology that is not based on humanity but then it would be alien to our being.

    Has this website been hacked? clicking on the yellow-red pic of the “weapons of Math destruction” book, one gets a Canadian cannabis site. (8/19/2022 evening)

    Dr. O’ O’Neil, my children are in college and are well. But it is haunting to me that some children have a block to understanding math. Some children so well in Calculus while others stall on algebra. I would gladly donate if you could change this small aspect of the world and alleviate the inadequate feelings these children feel. Best Bill
