紐約時報2011年2月8日科學版的這篇報導，描繪了在自由派居絕對統治地位的美國社會人文科學界存在的政治偏見，尤其是對保守派學者、學術觀點的偏見，值得一讀。
人人皆有偏見，要克服偏見，就要仔細傾聽不同的意見尤其是針鋒相對的意見。索羅斯說得很對。
此文要點如下﹕
弗吉尼亞大學社會心理學家Jonathan Haidt在今年美國個性與社會心理協會年會上，調查發現1000名心理學家中，自由派占80%，中間派與自由主義派（libertarian）只有30多人，保守派只有3人。但美國整個社會中保守派占40%，自由派占20%。這就導致社會人文科學界對保守派及其學術觀點構成某種歧視。
作者說﹕任何一個以某種價值觀為中心的團體，會演變成一個減持某種部落道德觀的社群，對有利于其價值觀的學術觀點就支持，排斥相反的學術觀點。
最後作者舉出1965年Daniel Patrick Moynihan 研究黑人未婚家庭問題遭到學術界排斥，和前哈佛大學校長桑莫斯因為對自然科學界女科學家較少現象的解釋而被迫辭職為例子。

Social Scientist Sees Bias Within
By JOHN TIERNEY
SAN ANTONIO — Some of the world’s pre-eminent experts on bias discovered an unexpected form of it at their annual meeting.
Discrimination is always high on the agenda at the Society for Personality and Social Psychology’s conference, where psychologists discuss their research on racial prejudice, homophobia, sexism, stereotype threat and unconscious bias against minorities. But the most talked-about speech at this year’s meeting, which ended Jan. 30, involved a new “outgroup.”
It was identified by Jonathan Haidt, a social psychologist at the University of Virginia who studies the intuitive foundations of morality and ideology. He polled his audience at the San Antonio Convention Center, starting by asking how many considered themselves politically liberal. A sea of hands appeared, and Dr. Haidt estimated that liberals made up 80 percent of the 1,000 psychologists in the ballroom. When he asked for centrists and libertarians, he spotted fewer than three dozen hands. And then, when he asked for conservatives, he counted a grand total of three.
“This is a statistically impossible lack of diversity,” Dr. Haidt concluded, noting polls showing that 40 percent of Americans are conservative and 20 percent are liberal. In his speech and in an interview, Dr. Haidt argued that social psychologists are a “tribal-moral community” united by “sacred values” that hinder research and damage their credibility — and blind them to the hostile climate they’ve created for non-liberals.
“Anywhere in the world that social psychologists see women or minorities underrepresented by a factor of two or three, our minds jump to discrimination as the explanation,” said Dr. Haidt, who called himself a longtime liberal turned centrist. “But when we find out that conservatives are underrepresented among us by a factor of more than 100, suddenly everyone finds it quite easy to generate alternate explanations.”
Dr. Haidt (pronounced height) told the audience that he had been corresponding with a couple of non-liberal graduate students in social psychology whose experiences reminded him of closeted gay students in the 1980s. He quoted — anonymously — from their e-mails describing how they hid their feelings when colleagues made political small talk and jokes predicated on the assumption that everyone was a liberal.
“I consider myself very middle-of-the-road politically: a social liberal but fiscal conservative. Nonetheless, I avoid the topic of politics around work,” one student wrote. “Given what I’ve read of the literature, I am certain any research I conducted in political psychology would provide contrary findings and, therefore, go unpublished. Although I think I could make a substantial contribution to the knowledge base, and would be excited to do so, I will not.”
The politics of the professoriate has been studied by the economists Christopher Cardiff and Daniel Klein and the sociologists Neil Gross and Solon Simmons. They’ve independently found that Democrats typically outnumber Republicans at elite universities by at least six to one among the general faculty, and by higher ratios in the humanities and social sciences. In a 2007 study of both elite and non-elite universities, Dr. Gross and Dr. Simmons reported that nearly 80 percent of psychology professors are Democrats, outnumbering Republicans by nearly 12 to 1.
The fields of psychology, sociology and anthropology have long attracted liberals, but they became more exclusive after the 1960s, according to Dr. Haidt. “The fight for civil rights and against racism became the sacred cause unifying the left throughout American society, and within the academy,” he said, arguing that this shared morality both “binds and blinds.”
“If a group circles around sacred values, they will evolve into a tribal-moral community,” he said. “They’ll embrace science whenever it supports their sacred values, but they’ll ditch it or distort it as soon as it threatens a sacred value.” It’s easy for social scientists to observe this process in other communities, like the fundamentalist Christians who embrace “intelligent design” while rejecting Darwinism. But academics can be selective, too, as found in 1965 when he warned about the rise of unmarried parenthood and welfare dependency among blacks — violating the taboo against criticizing victims of racism.
“Moynihan was shunned by many of his colleagues at Harvard as racist,” Dr. Haidt said. “Open-minded inquiry into the problems of the black family was shut down for decades, precisely the decades in which it was most urgently needed. Only in the last few years have liberal sociologists begun to acknowledge that Moynihan was right all along.”
Similarly, Larry Summers, then president of Harvard, was ostracized in 2005 for wondering publicly whether the preponderance of male professors in some top math and science departments might be due partly to the larger variance in I.Q. scores among men (meaning there are more men at the very high and very low ends). “This was not a permissible hypothesis,” Dr. Haidt said. “It blamed the victims rather than the powerful. The outrage ultimately led to his resignation. We psychologists should have been outraged by the outrage. We should have defended his right to think freely.”
Instead, the taboo against discussing sex differences was reinforced, so universities and the National Science Foundation went on spending tens of millions of dollars on research and programs based on the assumption that female scientists faced discrimination and various forms of unconscious bias. But that assumption has been repeatedly contradicted, most recently in a study published Monday in the Proceedings of the National Academy of Sciences by two Cornell psychologists, Stephen J. Ceci and Wendy M. Williams. After reviewing two decades of research, they report that a woman in academic science typically fares as well as, if not better than, a comparable man when it comes to being interviewed, hired, promoted, financed and published.
“Thus,” they conclude, “the ongoing focus on sex discrimination in reviewing, interviewing and hiring represents costly, misplaced effort. Society is engaged in the present in solving problems of the past.” Instead of presuming discrimination in science or expecting the sexes to show equal interest in every discipline, the Cornell researchers say, universities should make it easier for women in any field to combine scholarship with family responsibilities.
Can social scientists open up to outsiders’ ideas? Dr. Haidt was optimistic enough to title his speech “The Bright Future of Post-Partisan Social Psychology,” urging his colleagues to focus on shared science rather than shared moral values. To overcome taboos, he advised them to subscribe to National Review and to read Thomas Sowell’s “A Conflict of Visions.”
For a tribal-moral community, the social psychologists in Dr. Haidt’s audience seemed refreshingly receptive to his argument. Some said he overstated how liberal the field is, but many agreed it should welcome more ideological diversity. A few even endorsed his call for a new affirmative-action goal: a membership that’s 10 percent conservative by 2020. The society’s executive committee didn’t endorse Dr. Haidt’s numerical goal, but it did vote to put a statement on the group’s home page welcoming psychologists with “diverse perspectives.” It also made a change on the “Diversity Initiatives” page — a two-letter correction of what it called a grammatical glitch, although others might see it as more of a Freudian slip.
In the old version, the society announced that special funds to pay for travel to the annual meeting were available to students belonging to “underrepresented groups (i.e., ethnic or racial minorities, first-generation college students, individuals with a physical disability, and/or lesbian, gay, bisexual, or transgendered students).”
As Dr. Haidt noted in his speech, the “i.e.” implied that this was the exclusive, sacred list of “underrepresented groups.” The society took his suggestion to substitute “e.g.” — a change that leaves it open to other groups, too. Maybe, someday, even to conservatives.
