'1-drop rule' appears to persist for biracial individuals

09.12.2010
People consistently view biracials as members of their lower-status parent group

The centuries-old "one-drop rule" assigning minority status to mixed-race individuals appears to live on in our modern-day perception and categorization of people like Barack Obama, Tiger Woods, and Halle Berry.

So say Harvard University psychologists, who've found that we still tend to see biracials not as equal members of both parent groups, but as belonging more to their minority parent group. Their research appears in the Journal of Personality and Social Psychology.

"Many commentators have argued that the election of Barack Obama, and the increasing number of mixed-race people more broadly, will lead to a fundamental change in American race relations," says lead author Arnold K. Ho, a Ph.D. student in psychology at Harvard. "Our work challenges the interpretation of our first biracial president, and the growing number of mixed-race people in general, as signaling a color-blind America."

In the U.S., the "one-drop rule" -- also known as hypodescent -- dates to a 1662 Virginia law on the treatment of mixed-race individuals. The legal notion of hypodescent has been upheld as recently as 1985, when a Louisiana court ruled that a woman with a black great-great-great-great-grandmother could not identify herself as "white" on her passport.

"One of the remarkable things about our research on hypodescent is what it tells us about the hierarchical nature of race relations in the United States," says co-author James Sidanius, professor of psychology and of African and African American studies at Harvard. "Hypodescent against blacks remains a relatively powerful force within American society."

Ho and Sidanius, along with co-authors Mahzarin R. Banaji at Harvard and Daniel T. Levin at Vanderbilt University, say their work reflects the cultural entrenchment of America's traditional racial hierarchy, which assigns the highest status to whites, followed by Asians, with Latinos and blacks at the bottom.

Ho and colleagues presented subjects with computer-generated images of black-white and Asian-white individuals, as well as family trees showing different biracial permutations. They also asked people to report directly whether they perceived biracials to be more minority or white. By using multiple approaches, their work examined both conscious and unconscious perceptions of biracial individuals, presenting the most extensive empirical evidence to date on how they are perceived.

The researchers found, for example, that one-quarter-Asian individuals are consistently considered more white than one-quarter-black individuals, despite the fact that African Americans and European Americans share a substantial degree of genetic heritage.

Using face-morphing technology that presented a series of faces ranging from 5 percent white to 95 percent white, they also found that individuals who were a 50-50 mix of two races, either black-white or Asian-white, were almost never identified by study participants as white. Furthermore, on average black-white biracials had to be 68 percent white before they were perceived as white; the comparable figure for Asian-white biracials was 63 percent.

"The United States is already a country of ethnic mixtures, but in the near future it will be even more so, and more so than any other country on earth," says Banaji, Richard Clarke Cabot Professor of Social Ethics at Harvard. "When we see in our data that our own minds are limited in the perception of those who are the products of two different ethnic groups, we recognize how far we have to go in order to have an objectively accurate and fair assessment of people. That's the challenge for modern minds."

The team found few differences in how whites and non-whites perceive biracial individuals, with both assigning them with equal frequency to lower-status groups. The researchers are conducting further studies to examine why Americans continue to associate biracials more with their minority parent group.

"The persistence of hypodescent serves to reinforce racial boundaries, rather than moving us toward a race-neutral society," Ho says.

The research was supported by the Harvard University Anderson Fund.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
