The Use of Faces to Represent Points in k-Dimensional Space Graphically

This is my new favorite thing.

Herman Chernoff’s 1972 paper, “The Use of Faces to Represent Points in k-Dimensional Space Graphically.” The name is pretty self-explanatory: it’s an attempt to represent high dimensional data…through the use, as Chernoff explains, of “a cartoon of a face whose features, such as length of nose and curvature of mouth, correspond to components of the point.”

Here’s an example:

I just find this hilarious.

But, as crazy as this approach may seem – there’s something really interesting about it. Most standard efforts to represent high dimensional data revolve around projecting that data into lower dimensional (eg, 2 dimensional) space. This allows the data to be shown on standard plots, but risks loosing something valuable in the data compression.

Showing k-dimsional data as cartoon faces is probably not the best solution, but I appreciate the motivation behind it – the questioning, ‘how can we present high dimensional data high dimensionally?’

Don’t Mourn, Commonify! The European Commons Assembly Convenes

Across Europe, a vision of the commons has been emerging in the margins for many years.  But now, as the credibility of conventional politics and neoliberal economics plummets, commoners are becoming more visible, assertive and organized. The latest evidence comes from the first meeting of a newly formed European Commons Assembly. More than 150 commoners from 21 countries across Europe gathered in Brussels for the three-day event, from November 15 to 17.

The Assembly was organized by Sophie Bloemen and David Hammerstein of the Berlin-based European Commons Network, in collaboration with other commons advocates and organizations. Two sets of Assembly meetings were held at the Zinneke collective, based in an old stamp factory in Brussels that the nonprofit collective had reclaimed.  Another meeting was held in the stately European Parliament building, hosted by supportive members of the European Parliament who sit on the Working Group on Common Goods, within the Intergroup on Common Goods and Public Services.

Bloemen and Hammerstein recently wrote about the meetings:

This movement of commoners has been growing across Europe over the last decade, but last week it came together for the first time in a transnational European constellation. The objectives of the meetings were multiple but the foremost goal was to connect and form a stable but informal transnational commons movement in Europe. The political energy generated by bringing all these people together in this context was tremendous.

don’t confuse bias and judgment

“Even good and, at bottom, worthy people have, in our time, the most extraordinary fear about making judgments. The confusion about judgment can go hand in hand with fine and strong intelligence, just as good judgment can be found in those not remarkable for their intelligence.” — Hannah Arendt to Karl Jaspers, Dec. 29, 1963, translated by Elisabeth Young-Bruehl.

The best lack all conviction, while the worst
Are full of passionate intensity.
–W. B. Yeats

(Dayton, OH) A bias is a manifestation of cognitive limitations or weaknesses. It reveals that a person has failed to see the whole picture, to weigh evidence appropriately, to revise prior assumptions, to counter the influence of self-interest, or to grasp other perspectives. We are all subject to bias, constantly. It is wise to scrutinize our own and other people’s positions and opinions for signs of it. Certain professionals–reporters, researchers, teachers–are taught to acknowledge bias and to counter it. They are held accountable for any bias they appear to show. Anyone who writes in a public forum and purports to be a scholar or a teacher will sooner or later see the comment: “You’re biased!” (Or, just as likely, “Your bias!”, since grammar is not always the strong suit of the affronted.)

At the same time, each of us must make good judgments. Faced with almost any situation of any consequence, we can judge wisely and well, or judge badly, or fail to judge at all and thereby display negligence. Even journalists, scholars, and educators who advertise themselves as minimally biased must make constant judgments: what to cover, study, and teach, how to present information, whom to address, whom to take seriously, what counts as a legitimate position in a debate, and so on.

It’s essential to separate the language of bias from the language of judgment. They have different grammars: for instance, we say “good judgment” but not “good bias.” We accuse people of bias but not of judgment. A person can make the right judgment despite being biased; in fact, her bias may alert her to what really is the right conclusion. Or a person can somehow counter his own biases and yet make poor judgments. A typical example of the latter is a person who decides that taking a position would evidence bias and therefore fails to act–e.g., in response to a presidential candidate who is violating fundamental norms. Bias is empirically demonstrable, but demonstrating it does not prove that the speaker has reached the wrong conclusion. Judgment is wise or poor, but the difference is not empirically demonstrable in a straightforward way.

I think confusion between bias and judgment is one of the reasons that “even good and, at bottom, worthy people have, in our time, the most extraordinary fear about making judgments.” And that leaves the worst of us to display the most passionate intensity.

Join the NCDD Confab on Conversation Café, 12/19!

We’re excited to announce our next NCDD Confab Call will be featuring the co-creators of Conversation Café! Join us on Monday, December 19th from 1-2pm Eastern/10-11am Pacific for this one-hour call where we will learn more about this simple but powerful dialogue tool from the people who made it.convo-cafe-logo

This Confab will be an opportunity to learn all about the Conversation Café (CC) process, connect with people already doing Cafés, understand the basics of being a host, and share with NCDD how we can be of support to the CC network. Conversation Café is supported by a bank of resources for conversations and a wide network of CC hosts and groups, many of whom will be on the call. Register today to be part of the discussion!

The Confab will feature insights from NCDD supporting members Susan Partnow and Vicki Robin, two of the three original co-creators of the process. They will share with us how CC was started, their experience developing the process, and even run a miniature host training!

reg-button-2

Conversation Cafés are open, hosted conversations held in public spaces – not just in cafés! The CC process is elegantly simple – it’s nimble, accessible, and easy enough to be used very quickly by many people. As a process that moves participants from “small talk to big conversation,” our vision for CC, in part, is that it will be used to help communities address national and local crises that call for the immediate, real dialogue which we need in so many cc_cardsways today. We invite you to join this call to find out more about how you can start using CC today!

NCDD recently became the steward of the Conversation Café process because we are particularly well equipped to help new CC groups use other forms of dialogue and deliberation when the time is right, and we know that it’s a wonderful model for dialogue that can and should be widely adopted across the U.S. and the globe. NCDD would love to see more people in more places joining the CC network and engaging regularly in conversations that matter – register today to find out how you can be involved!

AllSides

From AllSides…

Unlike regular news services, AllSides exposes bias and provides multiple angles on the same story so you can quickly get the full picture, not just one slant.allsides_logo

At AllSides, we believe the way society gets its news and information affects the world around us. And lately it hasn’t been going well. News, social media and even search results have dramatically changed in the last several years, becoming so narrowly filtered, biased and personalized that we are becoming less informed and less tolerant of different people and ideas.

This is how it happens, and what we can do about it.

Blasted with the overwhelming 24-hour news noise of today, which is often loud, extreme, partisan and rude, we tend to do one of the following:
Disengage from trying to understand or solve society’s problems.
Block out different perspectives, becoming more close-minded and less tolerant of other people and ideas.

There’s a better way… AllSides sees a strong connection between our ability to comprehend and tolerate different opinions, and our ability to develop better schools, more jobs, more wellbeing, and less violence. So we decided to address the core problem – the overwhelming and often one-sided information flow.

How? Change the way we get information so it is easy to sort through the noise and see different perspectives. Armed with a broader view, we can resist attempts to manipulate us in one direction or the other. Instead, we can truly decide for ourselves:

Understand and appreciate different perspectives and people. We’re creating a better informed, less polarized world.

AllSides delivers technology and services to provide multiple perspectives on news, issues, and topics – and the people behind the ideas. With it, we get a broader, deeper understanding of the issues and each other so together we can build a more perfect union.

About the AllSides Bias Rating
The AllSides Bias Rating TM reflects the average judgment of the American people. Bias is normal. If you’ve got a pulse, you’ve got a bias. But hidden bias misleads and divides us. That’s why we have the AllSides Bias Rating.

Bias ratings can be a powerful tool. With it, we can easily look at a news story or issue from different perspectives just by looking at articles on the same topic but from sources that have different bias ratings. By understanding bias, we can understand topics and each other better.

Join us in making bias more transparent everywhere. Rate your own bias, learn how you compare to others (options on this page to the right), and help us rate the bias of other news sources.

How AllSides Calculates Bias
The AllSides patented bias detection and display technology drives arguably the world’s most effective and up-to-date bias detection engine. It’s powered by a combination of wisdom-of-the-crowd technology and the best statistical research and methodologies.

You drive the bias ratings. What you do at AllSides affects our bias ratings. That includes how you rate your own bias and how you rate the bias of news sites, especially through our blind bias surveys. All of this is added to our crowd data, which is statistically normalized to represent a balance of the American public.

Multiple methods for calculating bias. Our blind bias surveys, described in the graphic below, is our most complete and robust method for rating the bias of the source. That is not the only method we use, and often we don’t need anything as robust as that. The source itself might openly share its own bias, 3rd party research may have already determined the bias, an independent review might be decisive, or a broad consensus could be sufficient. Take a look at the variety of methods we use to measure bias.

allsides

Our bias detection engine gets smarter as time goes on. We are constantly evolving the bias engine. And, the more you participate, the better our ratings will be and the more sources we can rate. We also ask you to rate your own bias. We’re continuing to improve ways to help you get the most accurate bias self-rating so you can participate on AllSides and in life with transparency and self-awareness. Make the world a better place by understanding and sharing your own bias openly!

perspectives on identity politics

One of the many debates that has intensified after the 2016 election concerns “identity politics.” Some liberals blame it for the Democrats’ loss. Mark Lilla writes, “If you are going to mention groups in America, you had better mention all of them. If you don’t, those left out will notice and feel excluded. Which, as the data show, was exactly what happened with the white working class and those with strong religious convictions.” Others, like German Lopez, reply that politics is always about identity, that racial and sexual oppression are inescapable issues requiring explicit attention, and that the alternative to progressive identity politics is simply white nationalist identity politics.

The syllabus of my current philosophy class–planned months ago–concludes with a unit about identity and justice that we are entering right now. It follows a set of readings from political philosophy that are all egalitarian–in their various ways–and against discrimination, but that don’t delve deeply into questions of identity. And most (not all) of those writers have been White men. Now we turn to:

Some arguments from these readings in favor of identity politics:

People from oppressed groups must speak for themselves, not be the subjects of research or help from advantaged groups. Meanwhile, more differences need to be recognized. In current terms, justice requires acknowledging the “intersectionality” of race, class, gender, sexual orientation, national origin, etc., and hearing directly from people at each intersection. These two themes come together in a sentence by Lorde: “It is a particular academic arrogance to assume any discussion of feminist theory without examining our many differences, and without a significant input from poor women, Black and Third World women, and lesbians.”

People from oppressed groups need their “own strong solidarity,” built in somewhat separate spaces that are free from domination, so that they can “respond as a cohesive group” (Biko). Note that Biko uses “the black man” as a category that explicitly encompasses Zulus, Xhosas, Vendas, and South Africans of Indian origin, and implicitly includes black women. The logic of identity politics would suggest that he acknowledge more differences.

It’s not the job of oppressed peoples to educate their oppressors. “This is an old and primary tool of all oppressors to keep the oppressed occupied with the master’s concerns.” For instance, to say that women of color must educate white women “is a diversion and a tragic repetition of racist patriarchal thought” (Lorde). White women must educate themselves. This point seems somewhat in tension with Biko’s argument that “no group, however benevolent, can ever hand power to the vanquished on a plate. … No amount of moral lecturing will persuade the white man to ‘correct’ the situation.” Biko implies that oppressors will never educate themselves about oppression. But the two authors may agree that White people can and will change in the interests of their own liberation.

Oppressed peoples demonstrate better values than their oppressors. Biko celebrates traditional African religion (in the singular–presuming a unity across ethnic/national lines), in contrast to the “irresponsible people from Coca-cola and hamburger cultural background” who dominate South Africa. Identity politics of this type is not a form of cultural relativism but rather a call for better values.

Oppression is internal, psychological, implicit, and internalized by the oppressed. It’s not mainly about explicit power and rights. Therefore, changing explicit power and rights won’t solve matters. Biko depicts Black Consciousness as “the realisation by blacks that the most potent weapon in the hands of the oppressor is the mind of the oppressed.”

Identity politics is a path to deep transformation and revolutionary change for all. It is not a matter of “diversity, equity, and inclusion,” to use the current terminology popular in corporations and universities–i.e., accommodating or serving more people more fairly. Lorde might call that approach “the grossest reformism.” True identity politics is about liberation from current institutional arrangements. It is creative and innovative, “seek[ing] new ways of being” (Lorde).

What critics of identity politics hear as resentful complaints is often actually the sound of human beings flourishing. “Far from being constituted solely by their oppression and exclusion, group identities may be cherished as a source of strength and purpose [that] sustains us in struggle and makes political action possible” (Bickford.

Identity claims challenge supposedly universalist understandings of justice and the common good, since those were always “particular, biased, and selfish” (Bickford).

Oppressed peoples must devote attention to their own communities rather than mainly studying and seeking to change the dominant group. “Let us talk more about ourselves and our struggles and less about whites” (Biko). One reason is that there is simply much to learn and celebrate when one begins to look more closely at the marginalized group, its history and values.

Some arguments from these readings against identity politics:

Emphasizing differences divides people politically and prevents the construction of large coalitions. For that reason, it is simply a losing political strategy (unless, like Biko, one happens to live in a country where one oppressed group constitutes the majority). Further, no one will join a coalition for change as a result of being told that he or she is an oppressor. Being reminded of one’s privilege usually reinforces a desire to protect it. A winning strategy is to offer explicit benefits to all members of a large majority. That is the main argument of both Gitlin (1993) and Lilla (2016); and cf. Bayard Rustin, “From Protest to Politics: Future of the Civil Rights Movement,” Commentary (February, 1965).

The left is the heir to a tradition of explicitly universalistic values, whether those are liberal, Marxist, or Christian-inflected (e.g., in the Civil Rights Movement). “Universal human emancipation” (Gitlin) is the core of all authentically revolutionary and reformist politics. Its enemy is the kind of conservatism that prizes traditions, indigenous values, and social differences. Identity politics is a version of that kind of conservatism. Yes, progressive movements must address injustices related to sexuality, gender and color–not merely economics–but always in the explicit pursuit of a common good.

Identity politics has become apolitical because its practitioners are disconnected from elections, parties, unions, and reform movements and focus more on “symbolic representation” in places like universities and Hollywood (Gitlin). Also, they tend to depict “the oppressed [as] innocent selves defined by the wrongs done to them” and therefore demand protection from the government or institutions like universities and companies. That stance overlooks their own potential power and encourages them to ask others to manage and administer fairness, understood as a set of rules and regulations. Instead, they should be building power (Bickford, summarizing a view that she doesn’t hold).

Identity politics treats a short list of socially constructed labels as fixed, and thereby (ironically) reinforces the power of these labels. Identity is a “term thick with meanings” whose definition is rarely clarified (Bickford). It’s very unlikely that any particular identity is stable, uniform, or exclusive. Yet one sees in works like Biko’s a tendency to treat a given identity as essential. (However, as Bickford notes, wrestling with this problem has been a central focus for feminism for half a century now.)

I’d add some thoughts of my own:

First, we must consider the ways that identities, interests, and opinions can diverge. A person may have the identity of a woman, an objective interest in equal pay for equal work, and the opinion that this would make a just policy. These three things may be related in various ways, but they are also separable. Likewise, groups can be defined by identities, interests, or positions on issues.

Interests are valid and important. In fact, whose interests are served in a policy domain like health care can determine who lives and who dies. Nevertheless, we recognize that interests will conflict, that they require negotiation and compromise, and that, even in a reasonably just society, everyone’s interests will sometimes be outweighed.

In contrast, to assert an identity is to imply a right to be recognized and treated accordingly. After all, you can’t change your identity, yet you have a place in the society. No one should ask you to compromise your identity, only the interests that you assert. Finally, you are supposed to take other people’s interests and identities in mind as you critically reflect on your opinions. Most people should probably adopt opinions that are less predictably related to their identities and interests.

Interests, identities, and opinions are all “constructed” and malleable, but we are supposed to be maximally open to revising our opinions, yet protected against having to change our identities. The hard part is deciding whether a given claim is an expression of identity, interest, and/or opinion. The lines are very unclear, even to the person who makes a claim.

To make matters even more complicated, an identity can be something mostly embraced or mostly imposed. And it can be a name for a group that gives you strength or for a group to which your fate is tied, or both (Bickford, p. 120).

Second, practitioners of identity politics can miss the chance to be citizens in a particular sense. In this fascinating dialogue between Black Lives Matter leader Julius Jones and Hillary Clinton, Jones echoes Lorde’s argument that African Americans shouldn’t have to tell White people how to change. Complaining that the oppressed haven’t proposed specific solutions–as Clinton does–is “blaming the victim.”

The difference that is salient in Jones’ mind (understandably) is race: he is Black and Clinton is White; and she is asking him to solve the problems that White people have caused. But I think Clinton has a different difference in mind when she asks Jones to state his policy demands. She sees him as a citizen, and herself as a would-be leader. Citizens petition government for the redress of grievances–it even says so in the First Amendment.

To be sure, Jones is both a Black man and a citizen, so both perspectives are valid. But a danger inherent in identity politics is the suppression of one’s identity as a citizen. It is both a responsibility and a power of every citizen to advocate solutions to problems that others have created. As Biko argues, creators of injustice are unlikely to invent solutions themselves. It’s a political act to say what must be done.

Third, “intersectionality” can take forms that are hyper-individualistic. If many different factors constitute one’s identity–not just a short list like race, gender, and class, but also occupation, denomination, country of origin, region, linguistic dialect, birth order, party identification, age, generation, body type, and more–then each person has the grounds to assert a unique intersectionality. Perhaps nobody’s array of characteristics is actually unique in a nation of 323 million people, but within a given small group, everyone can claim her own niche.

In a culture that is generally individualistic, this potential is both attractive and a pitfall. As the concept of identity broadens beyond characteristics that have been used for brutal oppression, intersectionality offers an excuse to focus on everyone’s uniqueness at the expense of political solidarity and the distribution of basic rights. However, it’s hard to limit the characteristics that constitute identity when a huge range of factors do cause implicit bias. For instance, the same methods that demonstrate the pervasiveness of racial bias also show that we’re biased by partisanship, body type, age, etc. So why stop with race–or anywhere else? (This isn’t a rhetorical question. I’m inclined to think that we should stop with race, gender, and sexual orientation, and treat other differences as ones of opinion and interest, not of identity. But I would owe a defense of that view.)

Finally, we may need to think about new constructed identities. When historically marginalized people achieve hard-won and deeply valuable recognition, the traditionally dominant group is often left with an identity crisis. To take a foreign example: as Scots, Welsh people, Irish people, British West Indians, British Asians, and others assert–appropriately–their separate identities within Great Britain, Englishness is left to mean being a person whose ancestors lived in England. Since that group was exclusively White and traditionally dominant, it’s hard to celebrate one’s Englishness without being racist and xenophobic.

My point is not that we should sympathize with older White men who are struggling with their identities for the first time. Rather, we are all at risk unless they find identities that they can celebrate inclusively. A common response is to retell our national narrative so that everyone can feel inspired. This seems to me Barack Obama’s strategy and one of his great gifts as a national leader. But nations are awfully large and abstract. A different possibility that intrigues me is a city or metro area, because many people already feel loyal to their own cities, which are internally diverse. In the US, states with smaller populations may have the same value for rural people. So maybe we can reinforce identities as New Yorkers or Montanans, not to the exclusion of other identities, but as the basis of broader political coalitions.
