what the Facebook mood experiment says about current research ethics

(Washington, DC) Our ethical rules and procedures now badly fit the actual practices of research–burdening some inquiries that should be treated as free while allowing other studies to do real damage without any oversight at all. The Facebook “mood experiment” exemplifies these problems.

The case is well known, but I will summarize: Advised by a small group of academic researchers, including Cornell professor Jeffrey Hancock, Facebook experimented by changing the algorithms that select posts for users’ newsfeeds so that some users saw more happy material, and others saw more sad material, than they would have seen otherwise. It turned out that seeing happy stories led people to post more happy content of their own (contrary to some previous findings that happy news makes us feel resentful). The Cornell University Institutional Review Board (IRB), which is charged with pre-reviewing “research,” did not review this study because the professors were deemed to be insufficiently involved, e.g., they would not see the users’ data. Hancock et al. published the results, prompting an international outcry. Both the scholars and Facebook were denounced (and the former even threatened) for manipulating emotions without consent or disclosure.

I believe that the scholars were involved in “research” and so should have been reviewed by Cornell’s IRB. Given current principles of research ethics (as I understand them), the IRB should have required more disclosure and consent than Facebook actually provided. (But see a contrary argument here.) The key point is that users were influenced by the experimental manipulation—to a very small degree, but the magnitude of the impact could not be known in advance and was not actually zero. People were affected without being asked to participate or even told afterward what had been done to them. The scholars should have made sure that research subjects gave consent. Otherwise, they should have dropped their association with Facebook.

But I also believe that current IRB rules and procedures now poorly fit the realities of research.

On one hand, I am concerned about some over-regulation by IRBs. I start with the presumption that when we ask adults questions or observe them and publish our thoughts, that is an exercise of free speech protected by the First Amendment. IRB review of a research study that involves asking questions seems akin to prior censorship of a newspaper. In both cases, the writer could violate rights or laws, but then the affected parties should seek legal remedies. The IRB should not pre-review research that merely involves talking to or watching adults and writing what one observes.*

I realize that academic research based on mere conversation or observation can be harmful. Consider the “super-predator” theory of violent crime, which led to terrible social policies. But the problem with that research was its conclusion, not its method. An IRB has no purview over conclusions (or premises, or ideologies). We must respond to bad ideas with counter-arguments, not with prior censorship.

By the way, I have no complaint about the actual oversight of our own very capable and efficient IRB, which approves about a dozen studies of my team each year. My point is rather an abstract, principled one about the right to ask questions and write whatever one concludes.

On the other hand, manipulating people without their consent is problematic, and that is happening constantly and pervasively in the age of Big Social Science, microtargeting, and “nudges.” When academics experiment on people, they are generally subject to prior review and tough rules. But most social experiments are not done by academics nowadays. If Hancock et al. had chosen to stay clear of the Facebook study, Facebook might well have gone ahead anyway—with no review or scrutiny whatsoever.

One might argue that professors should be regulated more than companies are, because the former receive federal support and may have tenure, which protects them even if they act badly. But I am more worried about companies than about professors, because: 1) companies also frequently receive government support; 2) they may conduct highly invasive experiments without even disclosing the results, whereas professors like to publish what they find; and 3) some companies have enormous power over customers. For example, quitting Facebook over an ethical issue would impose a steep cost in terms of missed opportunities to communicate. Networks have value proportional to the square of their users, which implies that you cannot just decline to use an incumbent network that has more than a billion users. Agreeing to its “terms and conditions” is not exactly voluntary.

Philosophically, I’d be in favor of removing IRB review of research unless the research involves tangible impact on subjects, while regulating corporate research that involves experimental manipulation so that disclosure and consent are always required. I am not sure if the latter could be done effectively, fairly, and efficiently–and I am not holding my breath for anyone even to try.

*Notes: 1) I am not arguing the IRB review is literally unconstitutional. The IRB’s legally legitimate authority flows from contracts between the university and the government and between the university and its employees. My point is that First Amendment values ought to be honored. 2) When academics pay research subjects, that creates a financial relationship that the university should probably oversee on ethical grounds. 3) I am not sure about minors. The First Amendment argument still applies when subjects are minors, yet there seems to be a case for the university’s protecting human subjects who are under 18.

summit on civic engagement and higher education

MEDFORD/SOMERVILLE, Mass.—In collaboration with the White House, Tufts University’s Jonathan M. Tisch College of Citizenship and Public Service will convene higher education leaders to examine the important topics of civic engagement and active citizenship at a Civic Learning and National Service Summit to be hosted at Tufts this fall. Tisch College is a leader in civic learning, political engagement and service among young people.

The upcoming summit at Tufts, which was unveiled during the AmeriCorps 20th anniversary celebrations, will address two key topics: the value of civic engagement and how to measure civic engagement commitments and outcomes. The meeting is expected to include national policy makers, higher education scholars and practitioners, and other thought leaders in the fields of education, philanthropy, business, community and government.

Alan D. Solomont, Pierre and Pamela Omidyar Dean of Tisch College, said, “More than ever before, young people today are eager to serve and they are looking for support and inspiration. We welcome this opportunity to work with the White House, leaders in higher education, and others to assess how civic engagement and service can address pressing national challenges.” Solomont, former U.S. ambassador to Spain and Andorra also chaired the bipartisan board of directors of the Corporation for National and Community Service, the federal agency that oversees such domestic service programs as AmeriCorps, Learn and Serve America, VISTA and Senior Corps.

Peter Levine, associate dean of research at Tisch College who is spearheading the upcoming summit, added, “Many colleges and universities offer excellent programs that educate their students for democracy, but there is an urgent need to make these experiences expected for all colleges and students, and to assess the outcomes.”

Tisch College will announce further details of the Civic Learning and National Service Summit in the coming weeks.

The 4th International Degrowth Conference: New Convergences

In a sign of the growing convergence of alternative economic movements, the Degrowth movement’s fourth international conference in Leipzig, Germany, last week attracted more than 2,700 people.  While a large portion of the conference included academics presenting formal papers, there were also large contingents of activists from commons networks, cooperatives, the Social and Solidarity Economy movement, Transition Town participants, the “sharing economy,” and peer production. 

By my rough calculation from browsing the conference program, there were more than 350 separate panels over the course of five days. Topics ranged from all sorts of economic topics (free trade, business models for degrowth, GDP and happiness) to alternative approaches to building a new world (Ivan Illich’s “convivial society,” permaculture, cooperatives, edible forest gardens). 

Degrowth?  For most Americans, the idea of a movement dedicated to non-growth, let alone one that can attract so many people, is incomprehensible.  But in many parts of Europe and the global South, people see the invention of new socio-economic forms of production and sharing as critical, especially if we are going to address climate change and social inequality. 

Some degrowth activists are a bit defensive about the term degrowth because, in English, it sounds so negative and culturally provocative.  (The French term décroissance, meaning “reduction,” is apparently far less jarring than its literal transation as “degrowth.”)  One speaker at the conference conceded this fact, slyly noting, “But unlike other movements, it will be exceedingly hard for opponents to co-opt the term ‘degrowth’”!

In a 2013 paper, “What is Degrowth:  From an Activist Slogan to a Social Movement” (pdf), Frederico Demaria et al. write:  “”’Degrowth’ became an interpretive frame for a new (and old) social movement where numerous streams of critical ideas and political actions converge.  It is an attempt to re-politicise debates about desired socio-environmental futures and an example of an activist-led science now consolidating into a concept in academic literature.”  A new beachhead of this academic inquiry is a book Degrowth:  A Vocabulary for a New Era, due out in November.

academic freedom and the Steven Salaita case

I want to draw additional attention to the case of Steven Salaita, because it poses a threat to academic freedom. Here is the Change.org petition to reinstate him, which I have signed.

Last year, the University of Illinois granted professor Salaita a tenured faculty position as a professor of American Indian Studies, subject only to a vote of the Board of Trustees, which was described to him as a formality. He did what you’re supposed to do and resigned his position at Virginia Tech as he prepared to move to Illinois to start teaching this fall. He then composed a series of tweets against the Israeli invasion of Gaza.

With support of the Board of Trustees, the Illinois Chancellor revoked the position offered to Prof. Salaita. They made no bones about the fact that his tweets were the reason for their decision. In an explanatory letter, the Trustees endorsed freedom of speech but went on to say:

Our campuses must be safe harbors where students and faculty from all backgrounds and cultures feel valued, respected and comfortable expressing their views.  We … write today to add our collective and unwavering support of Chancellor Wise and her philosophy of academic freedom and free speech tempered in respect for human rights – these are the same core values which have guided this institution since its founding. … The University of Illinois must shape men and women who will contribute as citizens in a diverse and multi-cultural democracy. To succeed in this mission, we must constantly reinforce our expectation of a university community that values civility as much as scholarship.

Disrespectful and demeaning speech that promotes malice is not an acceptable form of civil argument if we wish to ensure that students, faculty and staff are comfortable in a place of scholarship and education. If we educate a generation of students to believe otherwise, we will have jeopardized the very system that so many have made such great sacrifices to defend. There can be no place for that in our democracy, and therefore, there will be no place for it in our university [emphasis added].

I have argued that a university may assess the quality and content of a professor’s public communications in deciding whether to hire her, publish her, or invite her to speak. “Civility” could be relevant to those judgments. (Jennifer Saul makes that point well.) However, it is very hard to see Prof. Salaita’s tweets as uncharacteristically lacking in civility or as especially demeaning. What they are is critical of Israel.

The Brown University professor Bonnie Honig interprets his tweets as the opposite of uncivil:

Here is a man of Palestinian descent watching people he may know, perhaps friends, colleagues, or relatives, bombed to bits while a seemingly uncaring or powerless world watched. He was touched by violence and responded in a way that showed it. In one of the tweets that was most objected to (Netanyahu, necklace, children’s teeth), Salaita commented on a public figure who is fair game and who was promoting acts of terrible violence against a mostly civilian population. I found that tweet painful and painfully funny. It struck home with me, a Jew raised as a Zionist. Too many of us are too committed to being uncritical of Israel. Perhaps tweets like Prof. Salaita’s, along with images of violence from Gaza and our innate sense of fair play, could wake us from our uncritical slumbers. It certainly provoked ME, and I say “provoked” in the best way – awakened to thinking.

Prof. Salaita is also a strong supporter of the “boycott of Israeli academic institutions,” which I happen to oppose. I would reject any academic boycott, and I disagree that the one country in the world to single out this way is Israel. But if Prof. Salaita was “unhired” because he supports the boycott, that is a clear violation of his freedom of speech and association. He is entitled to advocate a boycott; I just don’t endorse it.

As Michael Dorf explains, it’s a little bit complicated whether Prof. Salaita had a legal right to his position. Illinois was not obligated to hire him in the first place. It did, however, extend him an offer. He was told that the Trustees’ vote was a formality, and, as Brian Leiter writes, “Such approval clauses … had, previously, been pro forma at Illinois, as they are at all serious universities: it is not the job of the Board of Trustees of a research institution to second-guess the judgment of academics and scholars.” Thus, arguably, the University was constrained to hire him.

One could argue the reverse–that the Trustees’ vote is precisely meant to be a check on the decisions of the faculty and administration, to be used rarely but at the Board’s discretion. That would be a legal defense of the Trustees’ decision (I cannot say how plausible), but it is not a moral justification of this particular choice, whose basis appears clear enough.

I am not sure I would go far as to say that the University of Illinois has “repealed the First Amendment for its faculty.” Professors already in place there cannot be unhired. This case actually reinforces the value of tenure. But it is a problem if you can lose your academic freedom during a period of transition. And the bigger problem is: a major state university cannot seem to tolerate criticism of Israel.

hackademia

A university provides amazing resources and assets. I would even defend its overall structure to a degree. For one thing, it is robust against faddish ideas. If a university could change more easily, then a discipline like classics would have been shut down long ago. But classics is an exciting and generative field today (see this and this). It has survived the tough times because universities have institutionalized tenure, credentials, and departments to resist change.

Still, these structures frustrate many valuable innovations, especially when academia might interact better with the outside world. Courses must last for about 13 weeks even though real-life projects continue far longer than that. Professors must demonstrate regular results, but some especially worthy projects cannot yield publications quickly enough. Faculty must teach students who happen to be enrolled at their own institutions, even if more appropriate groups could be assembled by drawing on many colleges and including non-students.

These are just examples of the ways in which academia is “kludgy.” When you face a jury-rigged mechanism that still works for many purposes, you can just go with it, you can reject it and try to build something new, or you can add hacks: “inelegant but effective solutions.” Many of my favorite academics make hacks because they love the university but don’t think it quite works for their purposes. For instance, they teach their classes in state prisons. Or they assemble a set of “semi-formal learning groups” within a large state university and actually name it “hackademia.” Or they start meeting weekly for discussions of political economy and 30 years later have a virtual international network. Or they build tools with and for lay partners and reflect critically on the results. Or they create a Summer Institute without tuition, grades, credits, or official enrollment, and teach it off season at (for example) Tufts.

the commencement speaker controversies

IMF chief Christine Lagarde, former secretary of state Condoleezza Rice, activist Ayaan Hirsi Ali, and Colorado state Sen. Michael Johnston (D) are among the commencement speakers who have drawn objections from students this year. Several have withdrawn from speaking or been disinvited in the face of such criticism.

Compared to the people who decry student bigotry in these cases, I take a relatively complex, three-part view.

First, protesting a commencement speaker is not a violation of free speech; it is an act of free speech. Joel Whitney argues that point well in The New Republic. A commencement podium is not an open forum like Hyde Park Corner or a public access cable channel. It is allocated as a high honor to one person whom the institution explicitly endorses. Students may contest that endorsement.

For example, in announcing the choice of Johnston to be the Harvard Ed. School’s speaker, the dean said, “As a teacher, principal, and entrepreneur, Mike’s leadership has made a real difference in the lives of countless students.” (I can’t resist noting that the previous sentence contains a dangling modifier.) Dean Ryan continued, “As a legislator in the Colorado State Senate, [Johnston] is a nationally recognized advocate for school finance reform, fair teacher evaluations, and education equity. I believe that our community will be inspired, as I have been, by his passion and his willingness to find solutions to notoriously difficult challenges in education.”

That was a substantive statement and a prediction. The dean stated that the invitee was great and the whole community would be inspired by him. I have no objection to Sen. Johnston, but students are entitled to contest these claims.

Smith President Kathleen McCartney is right that “an invitation to speak at a commencement is not an endorsement of all views or policies of an individual or the institution she or he leads. … Such a test would preclude virtually anyone in public office or position of influence. Moreover, such a test would seem anathema to our core values of free thought and diversity of opinion.” But an invitation to speak at a commencement is a claim that the invitee is excellent in some respect, and the institution should expect objections if members of the community are known to disagree.

Second, when students protest a commencement speaker, neither the invitee nor the institution should back down. To withdraw in the face of criticism is to frustrate free speech. After Smith College invitee Lagarde, and some students objected, the IMF chief withdrew, saying, “In the last few days, … it has become evident that a number of students and faculty members would not welcome me as a commencement speaker. I respect their views, and I understand the vital importance of academic freedom. However, to preserve the celebratory spirit of commencement day, I believe it is best to withdraw my participation.”

If a commencement is just a celebratory occasion, spoiled by controversy as easily as a picnic by rain, then colleges should invite completely uncontroversial figures to share pabulum from the podium. If a commencement is an opportunity for learning, then it will draw dissent, and both the institution and the speaker should expect that. If they drop the speaker to avoid controversy, they don’t care about free speech.

Third, being exposed to views you disagree with is valuable. It’s educational and challenging. It is most valuable when the views are forcefully expressed by someone who genuinely holds them. Thus liberal students may benefit from hearing Lagarde, Rice, Ali, and Johnston, even if they don’t enjoy these talks all that much on their graduation day. There is a valid principle implied in the claim that these speakers have “free speech,” even if it’s wrongly interpreted to mean that they have some kind of individual right to give a commencement address. (If we have such a right, I’m cashing mine in and speaking next year at the University of Hawaii). “Free speech” doesn’t mean a right to give a commencement address, but it is shorthand for the value of exposure to challenging views.

Therefore, I don’t think students should express their objections in this form: “We despise the invitee and demand that she not speak here at all.” Instead, I think they should say, “We despise the views of the invitee for the following reasons and plan to make our arguments known during commencement.” That reflects an embrace of free speech rather than a fear of it. One model is the critical letter that Catholic University professors wrote to John Boehner after he was invited to speak there. They first offered a strong, substantive, moral critique:

Mr. Speaker, your voting record is at variance from one of the Church’s most ancient moral teachings. From the apostles to the present, the Magisterium of the Church has insisted that those in power are morally obliged to preference the needs of the poor. Your record in support of legislation to address the desperate needs of the poor is among the worst in Congress. This fundamental concern should have great urgency for Catholic policy makers. Yet, even now, you work in opposition to it.

That was actually a devastating rebuke. But the professors went on to welcome him to campus and held out hope that the interchange might influence him:

We congratulate you on the occasion of your commencement address to The Catholic University of America. It is good for Catholic universities to host and engage the thoughts of powerful public figures, even Catholics such as yourself who fail to recognize (whether out of a lack of awareness or dissent) important aspects of Catholic teaching. We write in the hope that this visit will reawaken your familiarity with the teachings of your Church on matters of faith and morals as they relate to governance.

I wouldn’t go so far as to say that every group of angry students must use exactly this model, but it is one worth considering. And then they should get their money’s worth on graduation day by engaging an interesting speaker, actively and critically.

become a professor, see the world

They say that academia is an ivory tower, sheltered from the tumult of human experience. But I’m fortunate, thanks to my job, to meet a very wide range of people in highly diverse settings. In fact, I don’t think many people in other walks of life are as fortunate in that respect. Within the past month, in the line of duty (so to speak), I have

  • Heard a “legalese-hatin’, cowboy-boot-wearin’, unafraid-to-admihuit-it liberal judge who rules from the [Arkansas federal] bench in a rocking chair” tell hootin’-and-hollerin’ jokes at the expense of his own profession.
  • Done a windshield tour of the poorest neighborhood in Champaign (IL), where the small decaying frame houses are scattered on the edge of the prairie.
  • Sat in the hushed office of the president of Duke, amid rubber trees, leaded Gothic windows, and framed honors, discussing the place of the humanities in public life.
  • Visited a game-design studio in Madison, WI, where hip young coders sit on stools of different heights and take breaks playing with Nerf balls and huge inflatable bowling pins.
  • Lectured in the Grecian rotunda of Mr. Jefferson’s University, a World Heritage Site.
  • And heard up-and-coming country singers in a bona fide Nashville honky-tonk on a Friday night.

We may be on the verge of wrecking it–and we certainly need better institutions to govern it–but it’s still a great country and a privilege to be able to see so many facets of it.

a day of two provosts

Today is the board meeting of the Jonathan M. Tisch College of Citizenship and Public Service at Tufts, where I work. Immediately after that meeting, I will fly to Durham, NC, to begin chairing the external review of Duke University’s Kenan Institute for Ethics, which plays a somewhat similar role to Tisch College. It’s a day of thinking about strategic plans for scholarly/activist centers at fine universities.

the Midwestern public universities

(Madison, WI) I am here very briefly for a meeting, having come from this morning from Urbana/Champaign. My calendar for this six month period also shows days in Ann Arbor, Indianapolis, Bloomington, Chicago, and Detroit.

I don’t think the full glory of our Midwestern state universities is sufficiently appreciated. As an academic myself, I am prone to overestimate the importance of higher education. But in my mind, this region is a prairie studded with fine research institutions, like Greek city states or walled Renaissance towns, each boasting its famous thinkers and its cosmopolitan reach, each tied to the state that sustains it (and each, unfortunately, ready to send a mercenary army into symbolic battle with the others). Champaign, IL–just for example–houses the second biggest university library in America, whose 13 million volumes put it behind only Harvard. I am reminded of what the late Tony Judt once wrote:

By far the best thing about America is its universities. Not Harvard, Yale, e tutti quanti: though marvelous, they are not distinctively American—their roots reach across the ocean to Oxford, Heidelberg, and beyond. Nowhere else in the world, however, can boast such public universities. You drive for miles across a godforsaken midwestern scrubscape, pockmarked by billboards, Motel 6s, and a military parade of food chains, when—like some pedagogical mirage dreamed up by nineteenth-century English gentlemen—there appears…a library! And not just any library: at Bloomington, the University of Indiana boasts a 7.8-million-volume collection in more than nine hundred languages, housed in a magnificent double-towered mausoleum of Indiana limestone.

I am not as critical as Judt of the “scrubscape” and its people. But I agree that there’s something miraculous about these huge intellectual conglomerates rising from the fruited plain at the command of their state legislatures. Hopping around the region on commuter planes, you see professorial types with the New York Review spread on their knees and kids in college hoodies. I know that the universities’ funding is now mostly private and their students come increasingly from a global elite. I know they can be ivory towers or tools of Monsanto or the NSA. And yet, when people assess our era centuries from now, I think the great Midwestern public universities will warrant respect.

free speech at a university

(Charlottesville, VA) From Mr Jefferson’s University, here are some thoughts about free speech in academia.

This may seem a simple topic: students and faculty should be able to express themselves freely. But I think it is quite complicated, for two reasons.

First, the university is all about adjudicating and rewarding quality, which conflicts with freedom. Every admissions letter, grade on a paper or a class discussion, decision about hiring or promotion, peer-review, invitation to give a lecture, or choice to acquire a book for the library is a decision about quality. The First Amendment gives you the right to say what you like. But if you write a weak argument for a paper, or express yourself on an irrelevant topic, you will get a lower grade. An institution thoroughly dedicated to making high-stakes assessments cannot also be a free-speech zone.

Second, educators and students both have claims to freedom of speech, and those claims may conflict. Duke Provost Peter Lange was once presented with this scenario:

In the Jan. 25 issue of the Chronicle, a Duke student complained about what he perceived as propagandizing in one of his classes: “One of the most insulting moments of my Duke education occurred in an ancient Chinese history class in spring 2003, when the U.S. was preparing to invade Iraq. Our teacher took a break from Confucius and the Han Dynasty to stage a puzzling “teach-in” about Iraq in conjunction with some national organization. During this supposedly neutral discussion, she regaled us with facts and assertions suggesting that the Iraq war was scandalous, foolish and doomed to fail …”

Of course, the Iraq war was scandalous, foolish and doomed to fail. But the teach-in, if accurately described, sounds improper to me. This kind of complaint leads to the provision in the “Academic Bill of Rights” that “Faculty will not use their courses for the purpose of political, ideological, religious or anti-religious indoctrination.” But that clearly trades off against a different provision in the same document: “Academic freedom consists in protecting the intellectual independence of professors …” An intellectually independent professor could choose to indoctrinate (or could speak in a way perceived as indoctrination by students who disagree). As Lange said, to ban that kind of expression limits the professor’s freedom of speech.

Perhaps professors have no valid claim freedom within their classrooms. Let them talk freely on their own time; when on the job, their purpose is to educate the students in their charge. That argument presumes that the value of free speech accrues to the speaker alone–it is about protecting her liberty, dignity, or sheer preference. But free speech also benefits the listeners, including listeners who sharply disagree. As J.S. Mill argued, you cannot test an idea unless you can hear it forcefully expressed by someone who actually believes it. To prevent professors from expressing their own ideas is to take those ideas off the table. In a famous statement from 1894, the University of Wisconsin Regents claimed that professorial freedom would lead toward truth:

We cannot for a moment believe that knowledge has reached its final goal, or that the present condition of society is perfect. … In all lines of academic investigation it is of the utmost importance that the investigator should be absolutely free to follow the indications of truth wherever they may lead. Whatever may be the limitations which trammel inquiry elsewhere we believe the great state University of Wisconsin should ever encourage that continual and fearless sifting and winnowing by which alone the truth can be found.

That is an eloquent expression of one side of the debate, but we should not ignore the other side: the rights of the students. A professor has the power to set the agenda and can assign grades for what students say and write. Untrammeled liberty by professors can definitely “chill” the freedom of expression of their students. I think the evidence that professors actually indoctrinate on any substantial scale is weak.* But it could happen.

To make things even more complicated, educators talk to educators; and students, to students. They should all be able to express themselves freely, and yet one’s expression can hamper another’s freedom and flourishing. That is especially true when the balance of power among them is unequal: for instance, when one side outranks or outnumbers the other or has more social clout. “Microaggressions” are exercises of speech that suppress the welfare–and perhaps the liberty–of others. To those who are wholeheartedly committed to confronting microaggressions, I would recall the importance of the speakers’ freedom. Unless people are permitted and even encouraged to say what they think, their ideas cannot be debated, and we can pursue the truth. On the other hand, to those who see the language of “microaggression” as oppressive political correctness, I would argue that some statements really do undermine the standing of our peers and are incompatible with the demanding norms of speech in a university. That doesn’t mean that rules against demeaning speech are wise, but we should be able to denounce a verbal aggression when it occurs.

Since I am here as the guest of the Jefferson Literary and Debating Society, among other sponsors, I will end by quoting Jefferson: “I would rather be exposed to the inconveniences attending too much liberty, than those attending too small a degree of it.” But he was also the author of the Senate’s “Manual of Parliamentary Practice,” with its elaborate rules to promote civility and mutual respect. That balance is difficult but crucial.

*(As I noted in a previous post, Yates and Youniss find that a powerful dose of Catholic social doctrine does not convert predominantly Protestant African American students, but provokes them to reflect on their own values. McDevitt and colleagues (in a series of papers including this one), find that political debates in school stimulate critical discussions in the home. Colby et al. find that interactive political courses at the college level, although taught by liberal professors, do not move the students in a liberal direction but deepen their understanding of diverse perspectives. Evidence of the effects of college ideological climates is ambiguous because of students’ self-selection into friendly environments.)
