Affirmative Action around the World

By Thomas Sowell

Thomas Sowell recently concluded a study of affirmative action programs around the world, from India and Malaysia to Nigeria and the United States. His findings? Such programs have at best a negligible impact on the groups they are intended to assist.

Empirical Evidence on Affirmative Action


For example, after many years of affirmative action policies in favor of New Zealand’s Maori minority, a Wellington newspaper reported in November 2000: “Extraordinarily, there appears to be little or no research into whether teaching kids the standard curriculum, but in Maori, has improved their educational outcomes.” The paper adds: “Nobody knows, because nobody seems to be asking.” Unfortunately, such disinterest in empirical consequences is not confined to New Zealand.

Quotas on trial


[...]

The late Justice Lewis Powell's much-praised opinion in the Bakke case said many worthy and thoughtful things. But the bottom line was that colleges and universities could keep on using racial quotas -- so long as they didn't call them racial quotas.

The dishonesty that is incidental to other policies is central to affirmative action. Most of what is said in support of this policy is either wholly unsubstantiated or demonstrably false.

What about the notion that affirmative action has helped blacks rise out of poverty? The black poverty rate was cut in half before affirmative action -- and has barely changed since then.

What about the notion that blacks would not be able to get into colleges and universities without affirmative action? After group preferences and quotas were banned in California's state universities, the number of black students in the University of California system has risen.

Fewer are attending Berkeley and more are attending other universities, whose normal admissions standards they meet. These students are now more likely to graduate, which is the whole point. Before, they were being used like movie extras to create a background -- until most either dropped out or flunked out.

What about the magic benefits of "diversity" -- a word repeated endlessly, without a speck of evidence of those benefits? If diversity is so essential, how does a nation like Japan, with a homogeneous population, manage to get its students educated (better than ours), its work done, and its people living in more harmony than we have?

The assumption that there is something strange about not having different groups "represented" in various occupations and institutions in proportion to their share of the population will not stand up to the slightest scrutiny. Massive scholarly studies of countries around the world have failed to turn up a single country in which the different racial or ethnic groups are proportionally represented in occupations or institutions -- except where governments have imposed quotas

[...]

Affirmative action has been tried in many countries around the world and has existed in India and Sri Lanka, for example, longer than in the United States. Seldom has it helped the poor and more often it has benefitted those who were already more fortunate.

Affirmative action has a track record of polarization in many countries, including lethal mob violence in India and a decades-long civil war in Sri Lanka. Do we need to continue down the road that these countries have traveled?



Quotas on trial: part II

[...]
People who are for or against affirmative action are usually for or against the theory of it. What actually happens under this policy gets remarkably little attention.

There is one study, however, that is virtually certain to be cited as evidence by those defending racial preferences and quotas, because it is regarded by liberals in the media and academia as definitive -- at least by those who confuse voluminous with definitive.

That study is titled "The Shape of the River" by former university presidents William Bowen and Derek Bok. While this book has lots of statistics, none of those statistics is specifically about the ostensible subject of the book -- black students who are admitted to colleges and universities with lower qualifications than white students, as a result of racial preferences or quotas.

[...] Bowen and Bok lump together those black students who were admitted under the same standards as white students with those black students who were admitted under lower standards. [...]

Other studies have confronted that issue. At universities where the test scores of black and white students are similar, their graduation rates have been similar. At universities where there are wide gaps between the average test scores of black and white students, there are usually wide gaps between their graduation rates.

At the flagship University of Colorado campus at Boulder, where the average SAT score of black students was more than 200 points lower than that of white students, only 39 percent of the black students graduated, compared to 72 percent of the whites.

At the University of Colorado at Denver, however, where the difference in SAT scores was only 30 points, half of all black students and 48 percent of all white students graduated within a six-year span. Where there were negligible differences in qualifications, there were negligible differences in results.

Comparisons of other institutions with large and small racial gaps in test scores show very similar patterns -- except for the Bowen and Bok study, in which affirmative action seems to have no negative effects. But one of the remarkable things about the Bowen and Bok study is that the raw data from which their statistics were compiled, and from which their many tables and graphs were put together, remain secret and off-limits to other researchers.

[...]

The sample used in the Bowen and Bok study was as questionable as their methods. That sample consisted of 24 private colleges and universities -- and only four state institutions. But only 9 percent of black college students attend private institutions, which constitute the bulk of the Bowen-Bok sample.

Nearly two-thirds of the black students in the study by Bowen and Bok had at least one parent who had graduated from college, which is by no means the norm for black students attending college. What all this shows is that highly atypical blacks attending a highly atypical sample of institutions have a different pattern from most blacks attending most institutions.

The 14th Amendment's requirement for equal treatment should not be overthrown or evaded because of one contrived "study."

Empirical Evidence on Affirmative Action

For example, after many years of affirmative action policies in favor of New Zealand’s Maori minority, a Wellington newspaper reported in November 2000: “Extraordinarily, there appears to be little or no research into whether teaching kids the standard curriculum, but in Maori, has improved their educational outcomes.” The paper adds: “Nobody knows, because nobody seems to be asking.” Unfortunately, such disinterest in empirical consequences is not confined to New Zealand.

 

[...]The implicit assumption, tenaciously held, is that great statistical disparities in demographic “representation” could not occur without discrimination. This key assumption is seldom tested against data on group disparities in qualifications. For example, as of the year 2001, there were more than 16,000 Asian American students who scored above 700 on the mathematics SAT, while fewer than 700 black students scored that high—even though blacks outnumbered Asian Americans several times over. Data such as these are simply passed over in utter silence—or are drowned out by strident assertions of “covert” discrimination as explanations of a dearth of blacks in institutions and occupations requiring a strong background in mathematics.

[...] Such data as can be gleaned from a variety of private sources in the United States suggest that the more fortunate American blacks receive a disproportionate share of the benefits going to blacks as a whole in the United States, just as the more fortunate Malays tend to benefit most from affirmative action in Malaysia or the more fortunate untouchables benefit from affirmative action in India.

Affirmative action programs also generate major social costs that fall on the population as a whole. Losses of efficiency are among these costs, whether because less-qualified persons are chosen over more-qualified persons or because many highly qualified members of non-preferred groups emigrate from a society where their chances have been reduced. However, the cost of inefficiency is overshadowed by the cost of intergroup polarization, violence, and loss of lives. Bloody and lethal riots over affirmative action in India are the most obvious examples, but there have also been young brahmins who have died by setting themselves on fire in protest against policies which have destroyed their prospects.

As the country which has had preferences and quotas for the less fortunate longer than any other, India presents the clearest historical picture of their consequences, as well as the clearest statistical picture. Its history is not one to encourage other countries to follow in India’s footsteps, much less the footsteps of Sri Lanka.

The history of Sri Lanka is even more chilling to those who are concerned about what actually happens in the wake of affirmative action policies, as distinguished from what was expected or hoped would happen. Sri Lanka’s well-deserved reputation as a country with exemplary relations between its majority and minority populations in the middle of the twentieth century has become a bitter mockery in the course of a decades-long civil war, marked by hideous atrocities. Despite Sri Lanka’s being a much smaller country than the United States, the number of Sri Lankans who have died in its internal strife exceeds the number of Americans killed during the long years of the Vietnam War.

The history of blacks in the United States has been virtually stood on its head by those advocating affirmative action. The empirical evidence is clear that most blacks got themselves out of poverty in the decades preceding the civil rights revolution of the 1960s and the beginning of affirmative action in the 1970s. Yet the political misrepresentation of what happened—by leaders and friends of blacks—has been so pervasive that this achievement has been completely submerged in the public consciousness. Instead of gaining the respect that other groups have gained by lifting themselves out of poverty, blacks are widely seen, by friends and critics alike, as owing their advancement to government beneficence.

[...]

Among black students in colleges and universities, those admitted under lower standards face a higher failure rate and those admitted under the same standards as other students graduate with their credentials under a cloud of suspicion because of double standards for minority students in general.

[...]


There is, however, some empirical evidence on the consequences of preferential admissions of individuals from privileged groups. When the president of the University of the Philippines had discretionary powers to admit particular students without regard to the usual academic criteria, the results were that (1) the great majority admitted this way were offspring of “the rich and powerful” and (2) “those admitted by presidential discretion performed worse than the rest of the audience.” At Harvard, back during the era when more than half of all alumni sons were admitted, those special admittees were disproportionately represented among students who flunked out.

[...]


Misleading Tactics

One of the unquantifiable, but by no means unimportant, consequences of affirmative action has been a widespread dishonesty, taking many forms. The redesignation of individuals and groups, in order to receive the benefits of preferences and quotas intended for others, has been common in various countries. In the United States, a special dishonesty has been necessary to square group preferences and quotas with the requirement of the American Constitution for equal rights among individuals. This has involved both concealment of the existence of preferential treatment and claims that such treatment is only a remedial response to existing discrimination. This adds insults to people’s intelligence to the injuries they may have received, or perceived themselves as receiving, and can only add to the backlash. There is all the difference in the world between saying that you have not had an even chance in life and saying that a particular individual or institution with whom you dealt has discriminated against you.

Another widespread kind of dishonesty, in both India and the United States, is the use of hazy, unverifiable criteria to conceal group preferences in college and university admissions [...]

In the United States, nebulous factors like “leadership” or “overcoming adversity” have likewise served as automatic offsets whose validity or lack of validity is not subject to proof or disproof. State bans on affirmative action in California and Texas public universities set off a wave of creative proposals for non-objective criteria for admissions, echoing what had happened in India decades before, where the state government of Mysore “suddenly exhibited an enhanced concern for the extra-curricular accomplishments of applicants to professional colleges.” Nothing is easier than to come up with rationales for non-objective criteria. In India’s state of Madras, for example, one supporter of such criteria argued that such criteria would “eliminate puny creatures with no personality from becoming engineers and doctors.”

[...]

History itself has been misrepresented as a way of strengthening the case for particular policies. The history of the aboriginal population in Australia has also been misrepresented in the quest for more current government benefits. In country after country, deception has been an integral part of the case for affirmative action. One of the most common forms of deception is the use of rationales which bear little or no relationship to what has actually been done. No sufferings by black Americans, past or present, can justify admitting white students to an elite San Francisco public high school over better-qualified Chinese American students who applied. Yet, once a policy of racial quotas has been authorized, the floodgates have been opened to such things, wholly at odds with the rationales for these quotas.

[...]


Alternatives to Affirmative Action

Concern for the less fortunate is entirely different from imagining that we can do what we cannot do. Nor is the humbling admission of our inherent limitations as human beings a reason for failing to do the considerable number of things which can still be done within those limitations. In America, at least, history has demonstrated dramatically that it can be done because it has already been done.

Americans need only look back to the beginning of the twentieth century to see what enormous social and economic progress has been made by some of the poorest and apparently least promising segments of the population. At the beginning of the twentieth century, only about half of the black population of the United States could read and write. Jews lived packed into slums on the lower east side of New York, with more overcrowding than in any slums in America today. As late as the First World War, the results of mass mental testing of American soldiers led a leading authority on mental tests to conclude that it was a myth that Jews were highly intelligent. The situation of Chinese Americans looked so hopeless that a popular expression of the time described someone facing impossible odds as having “not a Chinaman’s chance.”

Not even most optimists would have predicted at that time how much all these groups would rise over the next half century—before there were preferences or quotas. Even for blacks, at the center of current controversies about affirmative action, the decline in their poverty and their rise in the professions were both more dramatic before the federal government created affirmative action in the 1970s. With all these American ethnic groups—and others—what happened was not a transfer of benefits from the rest of the population, but a rising contribution from these minorities to the growing prosperity of American society as a whole, from which both they and the larger society benefited, as the less educated became more educated, as farm laborers and domestic servants acquired the skills and experience to take on more challenging work. This was not a zero-sum process, while redistribution is at best a zero-sum process, if it somehow manages to avoid disincentive effects and intergroup turmoil.

Why is this social process, with a proven track record, so little appreciated, or even noticed—and sometimes dismissed as a policy of “doing nothing”? Perhaps that is because, whatever its economic and social benefits, it offers few rewards to politicians, activists, and intellectuals or to those who wish to seem morally superior by denouncing society. The heroes of these groups’ rise are anonymous individuals, not public figures. Here is some history worth repeating—but only if the goal is the advancement of the less fortunate, rather than the aggrandizement of those who would be their guardians or spokesmen or elected officials.

 

Summary and Implications

[...] Nor can behavioral and other differences among the various populations themselves be arbitrarily banished from discussion by such pat phrases as “stereotypes” or “blaming the victim.” Causation is not blame and whether they are victims or not is precisely the question.

Are the Malay majority “victims” of the Chinese minority in Malaysia, the northern Nigerian majority victims of the Ibo minority, the Sinhalese majority victims of the Tamil minority in Sri Lanka, and numerous local majorities victims of the Chettiar or Marwari minorities in various parts of India? Are the white majorities in Canada and the United States victims of Japanese minorities? Or do these minorities simply perform more successfully in the competition of the marketplace and educational institutions? The dogma that statistical disparities demonstrate discrimination assumes an equality of performance that is virtually impossible to find in the real world.

Indeed, some of the same groups that are said to be discriminated against, on the basis of statistical disparities, show the same patterns of statistical dominance over the majority population in such fields as sports and entertainment—fields in which individual talents and efforts can produce success without the kind of cultural prerequisites, such as higher education, required in many other fields. Yet no one seriously believes that Maoris can keep white New Zealanders off that country’s sports teams, except by outperforming them on the field. Nor can black baseball players in the United States keep white players from hitting home runs, even though four of the top five totals of career home runs were hit by black players. Statistical disparities prove nothing about discrimination because they are common even in situations where those who are statistically dominant have no way to discriminate.

[...]

Despite a tendency to think of group preferences and quotas as transfers of benefits—a zero-sum process—there are in fact many ways in which these transfers can be negative-sum processes, in which what is lost by one group exceeds what is gained by another, making the society as a whole worse off. For example, when a group in which 80 percent of the students admitted to college succeed in graduating loses admissions to a group in which only 40 percent of the students graduate, then the first group must lose 800 graduates in order for the second group to gain 400 graduates. Moreover, it has been common in various countries around the world for groups whose students have lower qualifications to specialize in easier and less remunerative fields, as well as performing less well academically. Therefore the first group may lose 800 graduates, largely concentrated in mathematics, science, and engineering, while the second group gains 400 graduates largely concentrated in sociology, education, and ethnic studies.

This does not even take into account the intergroup polarization which group preferences and quotas provoke, and which can take many forms, including lethal riots, as in India, or outright civil war, as in Sri Lanka. By contrast, the gains made by less fortunate groups as a result of becoming better educated and better equipped with skills can be not only a net benefit to society as a whole, but also a source of greater respect for the group by others who see them as becoming more productive contributing members of society. In the case of blacks in the United States, much of their advancement has been of this sort, but the existence of affirmative action, and of particular horror stories growing out of it, has meant that blacks’ actual achievements have often been underestimated or disregarded. Affirmative action has meant almost a moratorium on recognition of the achievements of those designated as its beneficiaries, however few tangible benefits these groups may in fact have received.

Another way in which affirmative action can be a negative-sum process is by a withdrawal of members of non-preferred groups and the loss of their contributions to the society at large. A study of preferential policies in Malaysia reports the “emigration of non-Bumiputera professionals and the outflow of Chinese capital.” In post-apartheid South Africa, with affirmative action for blacks, many white government workers have taken early retirement and thousands of whites have emigrated annually. Those on the wrong side of preferential policies have likewise emigrated from Fiji, from Soviet Central Asia, from East Africa, and from other places where the skills and experience of these emigrants were sorely needed.

The empirical consequences of affirmative action preferences and quotas have been paid remarkably little attention—with hard data being sparse to nonexistent in some countries—while controversies surrounding these policies have been discussed in terms of the vision and the rationale behind them and the counter-vision and counter-rationales of critics. Vague, emotional, confused, and dishonest words, which are incidental aspects of many controversial issues, are central to discussions of affirmative action in countries around the world. Few such programs could stand on the basis of their actual empirical consequences. Nor are their moral bases any more solid.

[...]

Even when serious moral questions surround the past or present mistreatment of groups such as the untouchables in India or blacks in the United States, the remedies proposed rapidly spread far beyond redress of the misfortunes used to justify those remedies. Not only has the internal distribution of compensatory benefits borne little relationship—or even an inverse relationship—to the degree of misfortune within the affected groups, such benefits have spread to other groups far beyond the scope of the moral rationale and far exceeding in size the intended beneficiary groups.

Innumerable principles, theories, assumptions, and assertions have been used to justify affirmative action programs—some common around the world and some peculiar to particular countries or communities. What is remarkable is how seldom these notions have been tested empirically, or have even been defined clearly or examined logically, much less weighed against the large and often painful costs they entail. Despite sweeping claims made for affirmative action programs, an examination of their actual consequences makes it hard to support those claims, or even to say that these programs have been beneficial on net balance—unless one is prepared to say that any amount of social redress, however small, is worth any amount of costs and dangers, however large.

Excelente. Mas infelizmente estamos a anos-luz de ter a capacidade de debater este tema com maturidade aqui no Brasil.

Sabe o que isso me lembra, aliás? "A Revolução dos Bichos". Cada vez que alguém sugeria que os porcos estavam sendo tão maus quanto os humanos que administravam a fazenda antes, as ovelhas começavam a balir e abafar o discurso contrário com palavras de ordem. É bem parecido com o que acontece por aqui...

Do mesmo texto mencionado pelo Rodion:

The multicultural passion for hyphenation is not simply a fondness for syntactical novelty. It also bespeaks a commitment to the centrifugal force of anti-American tribalism. The division marked by the hyphen in African-American (say) denotes a political stand. It goes hand-in-hand with other items on the index of liberal desiderata—the redistributive impulse behind efforts at “affirmative action,” for example. Affirmative action was undertaken in the name of equality. But, as always seems to happen, it soon fell prey to the Orwellian logic from which the principle that “All animals are equal” gives birth to the transformative codicil: “but some animals are more equal than others.”

Total idiotice essa conversa de ações afirmativas!

Aqui no Brasil querem aprovar o tal estuto da igualdade racial (que tá mais pra estatuto da desigualdade racial). Esse tipo de coisa só faz aumentar cada vez mais, não só a impressão, como a desigualdade de fato.
O problema não é a cor das pessoas e sim as oportunidades que o estado é capaz de lhes proporcionar.
O governo tem é de melhorar os serviços públicos, principalmente propiciando uma educação (inclusive a técnico-profissionalizante) de qualidade aos mais probres, sejam estes brancos, negros, amarelos, verdes ... (a pobreza não escolhe cor).

A UNB já adota essa inbecilidade através de um absurdo sistemas de cotas. Chegou ao ridículo de considerar um irmão gêmeo branco e o outro negro, o que acabou sendo motivo de chacota nacional.

De mal a pior esse país aqui.

Ótimo texto. Já tinha lido partes dele antes, mas sempre é bom divulgá-lo.

Aliás, só pra botar lenha na fogueira, interessante que um tópico que traga evidências empíricas a respeito de um assunto controverso gere menos debate do que o que discute a suposta "justiça" por trás de uma medida sobre a qual não se pode dizer se é eficiente ou não...
