The weight of dead symbols

The photos in this post are mine, from my visit to Poland in late May and early June. The full set, annotated and viewable as a slideshow, is available here. I have provided English-language links where I could, but much of the information I used is only available in Polish. I marked those links with an asterisk, to save you a click if you do not speak the language.


The Polish-Soviet Friendship (officially, Brothership-in-Arms) Monument in Legnica was built in 1951*. It stands in the Słowiański Square, right in the city center. Two soldiers, one Polish and one Soviet, shake hands while a little girl held by the Pole embraces both of them. Poland, invaded by Germany and the Soviet Union acting in agreement, then devastated in the conflict between them, occupied and plundered by both even as its soldiers fought on every front they could find, finally claimed by Stalin for his Soviet empire, had to be represented as a little girl with no memory, history or trust issues, happy in the care of her saviours. Of course the child had to be a girl. A boy might not project the same naivetė, helplessness or passivity.

The monument is still there. I photographed it just a few weeks ago. The inscription, “To the Soviet Army heroes, from the people of the Legnica region,” had been removed in the 1990s and was never restored. The statue was vandalized repeatedly; past renovations notwithstanding, the neglect is palpable.

From 1952 until the end of the Cold War, Legnica was home to the headquarters of the Soviet forces stationed in Poland*. From 1984 to 1990, it also hosted the central command of the Western Theatre of Strategic Operations of the Warsaw Pact: had the Pact attempted to invade Western Europe, the military directions would have been issued from there. Estimates point* to 80-100K Russian soldiers and civilians stationed in town and at various unmapped bases nearby at any given time. The precise numbers and locations were classified, as was the exact layout of the Soviet-occupied parts of the city, surrounded by walls and guarded by armed soldiers posted at each entrance. The largest one, the “Kwadrat” [Square], measured 39 hectares and was a miniature city within a city, self-sufficient with its own shops, hospitals, cinemas, pools and sport venues. In total, the Soviets occupied about a third of the city’s pre-war area.


I grew up not far from that monument. I often walked past it on my way back from school but rarely thought about it. We acquired the skill of inattention in response to the relentless barrage of words and images that ranged from the hostile to the nonsensical*. “Workers of the world, unite!” “PZPR [the communist party] – the working class’s party, the leadership of the nation!” “We build socialism for people and through people!” Above all, invocations of friendship and brotherly love between Poland and the Soviet Union. Unlike ordinary human friendships that enter quietly and tie little knots here and there, that friendship could not be anything less than eternal, was written into the Polish constitution and had to be pledged and re-pledged every day in the streets of every city. We learned to tune it all out except to mock it. That skill continues to come in handy. Corporate language, often no less Orwellian than Soviet propaganda, washes off me like water off an oiled plate. I can look at ads and zap them off my computer screen without ever engaging with their content. (Sorry, Google and Facebook.)

Gender, conferences, conversations and confrontations

My departmental colleague Greg Martin has posted a paper entitled “Addressing the underrepresentation of women in mathematics conferences.” A comment and a bibliographical reference on page 9 of the text inform us that the paper is intended for publication in the Notices of the AMS. [Update, 3/20: I have been informed by the Notices of the AMS that they did not solicit the paper and will not publish it.] In the acknowledgement at the end, the author thanks “other friends and colleagues, too numerous to list here, for their encouragement and inspiration.” Given that we are employed in the same department, and that I often write here about gender, one might ask whether that large number included me. I would like to make it clear that it did not. Had anyone asked for my opinion, I would have discouraged it and, instead, encouraged the Notices to solicit a very different article.

I would have told them that such an article needs to be grounded in extensive firsthand knowledge of our practices related to conference organizing in mathematics. For that reason, it should be written by someone–better yet, by a group of authors–with broad experience in organizing conferences and an established record of promoting women and minorities in that context. It is not enough to point to the discrepancy between the gender proportions at the bottom and the top of the pyramid, and fall back on studies of gender bias in other fields for an explanation. It is necessary to diagnose the mechanisms that lead to it, addressing directly and specifically our actual practices. That requires experience and access to information including confidential and protected material. If a recommendation is made, it should first be tested in real-life conference organizing, and the results of such attempts should be analyzed. I would also insist that it should be written by a woman or a team of authors including women, and not only because women have direct knowledge of gender bias that men cannot have. Were the Notices to publish an article on the subject, it is likely that this would be suggested as a resource for prospective conference organizers; I know of at least one such attempt before the paper was even submitted. I do not believe that the article can have the necessary moral authority without a woman’s name on it.

Martin starts with, “In the context of mathematics conferences, the subject of gender is somewhat of a taboo. Certainly, bringing up the subject at all during a conference would be deemed outside the norm.” This is not true in my experience. I have organized many conferences. The NSF “broader impact” criteria include “broadening the participation of groups underrepresented in science, mathematics, engineering and technology,” and this carries disproportionate weight in mathematics as other ways of meeting these criteria are rarely available to research mathematicians. Mathematics institutes, in addition to being funded by the NSF and therefore accountable to it, often have their own diversity mandates. The organizers of conferences held under their auspices must report explicitly the number of women speakers and are often asked to increase that number. I have also attended many conferences. I have not found it uncommon, or outside the norm, for the participants to talk about gender-related issues in the space reserved for unstructured interactions. I have had many such conversations myself and have witnessed many more.

It is possible that Greg Martin’s experience has been different. He and I rarely attend the same conferences or talk to the same people. But these sentences point to a deeper issue, and not just with this article: the common belief that the gender problem in mathematics could be fixed if we only talked more about it. I disagree. I have said that I witnessed many conversations on gender at mathematics conferences. I did not say that they were all part of the solution. “Bringing up the subject” can mean complaining about the NSF diversity requirements, pointing out this woman or that one who was clearly only invited because of affirmative action, or explaining how we would all gladly invite more women if only they were a little bit better, even as we reassure everyone within hearing range that we totally believe in gender equality. We sure talk about gender. In terms of pure volume, we may be close to the saturation point already. It is not clear that this is helping.

There follows a long overview of literature on implicit bias and gender discrimination. None of these studies or findings are new to me. I’ve seen them on many feminist blogs and Twitter feeds, have linked to them and written about them here. Still, there is no shortage of people who are less familiar with the subject, and I will be glad if such a reading list is delivered to the mailbox of every mathematician in America and beyond. That is long overdue.

Unfortunately, the original research is problematic. It includes an analysis of the gender make-up of two conferences, the 2014 International Congress of Mathematicians in Seoul and the 2014 Joint Mathematics Meetings of the AMS and the MAA in Baltimore. For both meetings, Martin sets the target benchmark for female participation at 24%, based on the fact that at least 24% of doctoral degrees in mathematics at U.S. institutions were granted to women in each year since 1991.

The less complicated narratives

Steven Attewell makes good points about Selma:

Selma is definitely the best film yet made about the Civil Rights Movement. And I say this because it is, more than a biopic about Martin Luther King Jr. himself, a movie about movements. When King bursts into the kitchen of Richie Jean Jackson early in the film, he brings with him a large crew of experienced SCLC activists, who fiercely debate tactics and policy and who are shown doing the heavy lifting of activism – leading trainings, working with local activists, working phone banks, organizing supplies for the 50 mile march from Selma to Montgomery, organizing volunteers, working the media, and actually going out and marching and getting beaten to hell in front of the media. We also meet a diverse crew of activists outside of the SCLC crew, from local volunteers like Jimmie Lee Jackson and his family and Annie Lee Cooper, to SNCC activists like James Forman and John Lewis who have their own ideas about movement strategy, to Malcolm X, who shows up very much aware that his radical cred can be used to make King’s activism more palatable to whites. […]

However, the choice to depict Johnson as an opponent to the Voting Rights Act is one that has ramifications for the movie’s argument about how movements work. In this film, presidents like Johnson are shown as obstacles to be overcome.

And to me, that’s less interesting and arguably less radical than the story that even a president who’s actively preparing a Voting Rights bill and pushing it through Congress couldn’t get it passed without Selma giving the issue the “fierce urgency of now,” (or without the massive majorities he got in 1964 and would lose in 1966) as Julian Zelizer points out in his new, eponymous book. After all, it’s pretty conventional on the left to say that grassroots activists have to struggle against an uncaring establishment and force it to act – it’s more novel to point out that grassroots activists have to struggle, even with an establishment that’s on their side, and that sometimes the establishment might even seek out grassroots activists to cause a crisis for them to solve. Likewise, I think the point that legislation leads to long-term structural political change, and that winning the election after the march succeeds is a vital part of making sure that the success is lasting, needed more than a mention in the end credits.

Selma is excellent and you should see it if you haven’t already*. But I also promised a long time ago that I’d write one more post about Tony Judt’s Postwar, specifically about his treatment of the end of communism in Eastern Europe. This is a perfect opportunity to do that.

On proof and progress in feminism

The recent allegations against several celebrities have led to a broader conversation on how we, as a society, don’t believe women. In a “he said, she said” situation, we trust the man and assume that the woman is either mistaken or lying. “Taking us seriously” means that we are advised of such and offered an explanation for our dismissal instead of simply being dismissed outright. It’s not only personal bias, conscious or not; there are institutional mechanisms perpetuating this state of affairs. No proof is ever sufficient if it comes from a woman. Should she present multiple affidavits, all signed and notarized in triplicate, she’ll be informed that they do not prove her claim; she, on the other hand, probably violated multiple rules and procedures by collecting and presenting her evidence in the first place. She should stop before she gets into more trouble.

Meanwhile, there’s a growing crop of men who, having declared themselves as feminists, proceed to lecture women on how they should go about equity-related matters. At a recent tech conference, a panel of male allies told women that they should just apply themselves a little bit more; another male panelist implored them to wait quietly for their good karma. Closer to home, I’ve been told repeatedly and earnestly that sexism in math would be solved if we only had unmoderated comments on research articles, or anonymous journal submissions, or some such. We’re instructed on what level of anger befits a feminist (low to nonexistent), which fights we can pick without belittling our cause (not many, and most of them were in the past), and how to address men in order to not alienate them (politely and with due deference). We’re offered advice that’s worse than useless in that we have to spend our time rebutting it. We have policies and procedures pushed on us that promote, at our expense, some alien, estranged concept called “women” that does not include us.

This is all of a piece with the culture that casts men as leaders and experts, and women as supporting characters and understudies. In feminism, as in everything else, men believe that their superior knowledge and understanding bestows upon them a natural authority and responsibility. Our equality will be measured, apportioned and dispensed to us by polite, congenial men, men who will invite us to advise and support them as needed, but will always reserve the right to overrule us should they deem it necessary.

Basic things are basic. You spoke over women in committees, silenced them in faculty meetings, denied their requests, and then you don’t understand why they don’t accept your valiant leadership with gratitude? Golly gee, the world can be so unfair. That said, we do need allies. We could use more help. And there are men who, I’m sure, have all the best intentions. And that makes it so much more disappointing when these men dismiss our hard-earned insight in favour of their own solutionism, where each problem has an easy answer and those that do not are declared nonexistent.

Consider the large body of research on unconscious racial and gender bias. Have you also paid attention to the public responses to such studies? Most men, and some women, might read a study on gender bias with astonishment and disbelief, having had no previous intimation that this was going on. They might argue back that not all men do this, and that some women succeed in tech, and women have babies and girls play with dolls. Above all, they will demand more proof. If it’s a lab study, it needs to be repeated and checked against real life statistics. If it’s statistics, then individual cases must be examined for other possible explanations. If it’s individual stories, that’s just anecdata, we need statistics and/or a lab study. To ensure appropriate collegiality, all this must be provided without hurting men’s feelings or contradicting their beliefs.

Many women, meanwhile, respond to the results of the same study with a collective “duh” on social media. It’s hardly news to them that X happens, even if the numbers might still surprise them. They see it all the time; they also see Y, Z, W, and much more. They had talked about it between themselves, thought about it, written about it at length. Nonetheless, they are the first to point out the importance of the study, to praise and publicize it. They do so because it legitimizes their own experience in the eyes of others, opens up a window in which they might be permitted to speak out. It offers evidence other than the flimsy, useless threads of their own words.

None of their knowledge is available to those who insist on conducting every conversation as it if were a criminal trial. There’s no chance of normal discourse. Why did I say “they see it all the time” when there was this one time it didn’t happen? And that other time, too? Who are “they,” anyway? Can we have their names and institutional affiliations? Have we heard the other side of the story? And so women are studied as if we were baboons, endangered for some reason but incapable of articulating what it is that ails us, so that researchers have to rely on statistics, experiments and third-party accounts.

Do you care about proof, or about progress? You can read all the peer-reviewed research, attend all the official panels, and you’ll still only see the tip of the iceberg. You’ll see the isolated facts but you’ll have no idea how to connect them. You’ll see the molehill that can be proved in a scientific paper, but not the mountain that we are forbidden to talk about for confidentiality reasons, and not the one that we stopped talking about because nobody believed us, either.

This post, unlike most of what I write, has no hyperlinks. This is on purpose. There are many related links in my earlier posts, and more in my Twitter feed linked on the sidebar. It’s easy enough to google around and find more. Alternatively, you could entertain the possibility that what I’m telling you is the actual truth of my experience. That would be a good start.

ICERM postdoctoral positions

I’m co-organizing the program Dimension and Dynamics at the Institute for Computational and Experimental Research in Mathematics in Spring 2016. (Yes, this means that I hope to participate in the program. Details to follow when they are finalized.) ICERM has several postdoctoral positions associated with the program, one for the full academic year and four for the semester. Applications should be submitted via MathJobs. There is also funding for program visitors and workshop participants; the ICERM webpage has more details on that.

The program covers various aspects of dimension theory and dynamics, from ergodic theory to hyperbolic dynamics to computation. In my own research, I’ve been increasingly attracted to connections between dimension theory and dynamical systems on one hand, and harmonic analysis and additive combinatorics on the other. I look forward to doing more work in that direction in the next few years.

Diversity and mathematics

bell curve1

Mother Jones, last year:

According to a new psychology paper, our political passions can even undermine our very basic reasoning skills. More specifically, the study finds that people who are otherwise very good at math may totally flunk a problem that they would otherwise probably be able to solve, simply because giving the right answer goes against their political beliefs.

I was reminded of it while reading the article “Does Diversity Trump Ability? An Example of the Misuse of Mathematics in the Social Sciences” in the Notices of the AMS. The author, Abigail Thompson, takes on a well known and widely cited paper:

“Diversity” has become an important concept in the modern university, affecting admissions, faculty hiring, and administrative appointments. In the paper “Groups of diverse problem solvers can outperform groups of high-ability problem solvers” [1], L. Hong and S. Page claim to prove that “To put it succinctly, diversity trumps ability.” We show that their arguments are fundamentally flawed.

Why should mathematicians care? Mathematicians have a responsibility to ensure that mathematics is not misused. The highly specialized language of mathematics can be used to obscure rather than reveal truth. It is easy to cross the line between analysis and advocacy when strongly held beliefs are in play. Attempts to find a mathematical justification for “diversity” as practiced in universities provide an instructive example of where that line has been crossed.

Thompson proceeds to shred both the “mathematical theorem” and the numerical examples from the Hong-Page paper. The actual paper is available here, and I have satisfied myself that Thompson is not unfair in her mathematical analysis. Her article, however, does not exist in a vacuum. It will be read in mathematics departments, organizations and committees where “diversity” is viewed as a bureaucratic imposition made on them by distant administrators who don’t understand research, even as their few women faculty often find themselves alienated and sidelined. That’s why I would like to add a few things.

First, there are many sound reasons for diversity that have nothing to do the article in question. (I will restrict this post to the benefits of diversity per se, independently of how that diversity was achieved. Affirmative action has its own reasons and will get its own post soon.) It should be common sense, not a mathematical theorem, that there are advantages in having a wider perspective and more than one problem-solving approach. Continue reading
