A New York Times oped:
Diversity Makes You Brighter
By SHEEN S. LEVINE and DAVID STARK DEC. 9, 2015
AFFIRMATIVE ACTION is back before the Supreme Court today. The court has agreed to hear, for the second time, the case of Abigail Fisher, a white applicant who claims that she was rejected by the University of Texas at Austin because of her race. Ms. Fisher invokes the promise of equal protection contained in the 14th Amendment, reminding us that judging people by their ancestry, rather than by their merits, risks demeaning their dignity.
Upholding affirmative action in 2003, in Grutter v. Bollinger, Justice Sandra Day O’Connor argued that it served the intellectual purpose of a university. Writing for the majority, she described how the University of Michigan aspired to enhance diversity not only to improve the prospects of certain groups of students, but also to enrich everyone’s education.
As you can see from this video, everyone’s education is enriched by Diversity. Intellectual discourse thrives when everybody is hyperaware of their racial grievances.
Ms. Fisher argues that diversity may be achieved in other ways, without considering race. Before resorting to the use of race or ethnicity in admissions, the University of Texas must offer “actual evidence, rather than overbroad generalizations about the value of favored or disfavored groups” to show that “the alleged interest was substantial enough to justify the use of race.”
Our research provides such evidence. Diversity improves the way people think. By disrupting conformity, racial and ethnic diversity prompts people to scrutinize facts, think more deeply and develop their own opinions.
As we all know, only conformists are skeptical about the value of diversity. Everybody who is anybody believes that diversity is awesome.
Our findings show that such diversity actually benefits everyone, minorities and majority alike.
This is the kind of assertion that everybody wants to believe these days. You can have your cake and eat it too: diversity and rake in the dough. We saw it with the Housing Bubble, which was concentrated in highly diverse neighborhoods. It eventually turned out that opinions on the value of houses in highly diverse neighborhoods were disastrously stupid, but who can remember what happened way back in the last decade.
To study the effects of ethnic and racial diversity, we conducted a series of experiments in which participants competed in groups to find accurate answers to problems. In a situation much like a classroom, we started by presenting each participant individually with information and a task: to calculate accurate prices for simulated stocks. …
We assigned each participant to a group that was either homogeneous or diverse (meaning that it included at least one participant of another ethnicity or race). To ascertain that we were measuring the effects of diversity, not culture or history, we examined a variety of ethnic and racial groups. In Texas, we included the expected mix of whites, Latinos and African-Americans. In Singapore, we studied people who were Chinese, Indian and Malay. (The results were published with our co-authors, Evan P. Apfelbaum, Mark Bernard, Valerie L. Bartelt and Edward J. Zajac.)
The findings were striking. When participants were in diverse company, their answers were 58 percent more accurate. The prices they chose were much closer to the true values of the stocks. As they spent time interacting in diverse groups, their performance improved.
In homogeneous groups, whether in the United States or in Asia, the opposite happened. When surrounded by others of the same ethnicity or race, participants were more likely to copy others, in the wrong direction. Mistakes spread as participants seemingly put undue trust in others’ answers, mindlessly imitating them. In the diverse groups, across ethnicities and locales, participants were more likely to distinguish between wrong and accurate answers. Diversity brought cognitive friction that enhanced deliberation.
For our study, we intentionally chose a situation that required analytical thinking, seemingly unaffected by ethnicity or race. We wanted to understand whether the benefits of diversity stem, as the common thinking has it, from some special perspectives or skills of minorities.
See. Diversity makes you rich. Only idiots doubt that.
What we actually found is that these benefits can arise merely from the very presence of minorities.
They’re like sacred totems. You should make sure to have some around.
In the initial responses, which were made before participants interacted, there were no statistically significant differences between participants in the homogeneous or diverse groups. Minority members did not bring some special knowledge.
The differences emerged only when participants began interacting with one another. When surrounded by people “like ourselves,” we are easily influenced, more likely to fall for wrong ideas. Diversity prompts better, critical thinking. It contributes to error detection. It keeps us from drifting toward miscalculation.
And that explains why Obama was beaten so badly by Romney in 2012: just look at the nondiverse Obama 2012 Brain Trust.
Ethnic diversity is like fresh air: It benefits everybody who experiences it.
These researchers have no doubt used their discovery that diversity makes for better stock picking to make billions as hedge fund managers.
They have made billions off their discovery, haven’t they?
