(Press-News.org) COLUMBUS, Ohio - Black players in the NBA have 30% greater odds of leaving the league in any given season than white players who have equivalent performance on the court, a new study finds.
The results were driven mostly by bench players, who are the majority of those in the league, but who average less than 20 minutes of action per game.
These findings suggest that even in the NBA - a league in which Black players make up 70-75% of those on the court - African Americans face discrimination, said Davon Norris, lead author of the study and a doctoral student in sociology at The Ohio State University.
"If there is going to be anywhere in America where you would expect there wouldn't be racial disparities, it would be the NBA," Norris said.
"But even here we find there is an advantage to being white for most."
The disparity is not obvious if you look at raw data on career lengths, because Black and white players leave the league at similar rates, said study co-author Corey Moss-Pech, a PhD graduate of Ohio State who is now a postdoctoral research fellow in sociology at the University of Michigan.
"We see the effects when we account for performance," Moss-Pech said.
"Black players tend to be better than white players, according to the data. They should have longer careers, but they don't."
The study was published recently in the journal Social Forces.
The researchers analyzed the career lengths for all NBA players beginning their career in or after the 1979-80 season through the conclusion of the 2016-17 season.
The final sample included 2,611 players, who were considered for the purposes of the study as either Black, white or international.
The average career length in the NBA is only five years, Norris said, most likely because most players are cut by teams before they would choose to leave.
In the main analysis, the researchers evaluated performance using the same advanced metrics that NBA teams use, including player efficiency rating, offensive win shares and defensive win shares.
These measures combine stats like points scored, rebounds, steals and blocks into succinct comprehensive measures of performance.
They separated players into starters/key players (more than 30 minutes on the court per game), role players (between 20 and 30 minutes per game) and bench players (fewer than 20 minutes per game).
After taking on-court performance into account, there were "stark differences" in how long equally effective Black and white players stayed in the league.
For example, take the defensive win shares statistic, which measures the ability to prevent opposing teams from scoring. The researchers compared career length for white and Black players who were identical on this statistic, at the 50th percentile.
The proportion of white players at this level who left the league by their fifth season was 26%, significantly lower than the 33% of Black players who performed just as well but were no longer in the league after five years.
Not all in the NBA were treated similarly.
For those who were starters, there was no significant difference in career length based on race. For role players, Black players were at a disadvantage, but the difference was not large enough to be statistically significant.
However, there was a significant difference in bench players based on race, Norris said. About half of Black players and 65% of white players in the NBA are classified as bench players in this study.
"For those on the bench, being white really gives you an advantage," he said. "We have these cultural stereotypes that white men distinctly lack ability at basketball, but our analysis shows that this has little bearing on how long they last in the league."
The question becomes why. It doesn't appear to be associated with the race of the coach. The study found similar results whether there was a Black or white coach.
While the data in the study can't explain the disparity, Moss-Pech said, it may be that Black players are viewed differently from their white teammates off the court.
"Bench players may be more valued for their 'locker room presence' or for being a 'good teammate' than for their in-game performance. But concepts like 'good teammate' are likely racialized in a biased way that benefits white players," he said.
"White players may fit more comfortably into these team and organizational roles. We need more research that directly examines whether white and Black bench players are perceived differently in the media, by fans, by players or by decision makers."
The results have implications beyond the NBA, Norris said. They suggest that efforts to objectively measure employee effectiveness won't be enough to eliminate discrimination.
"NBA teams have all these stats available to measure productivity, and distinguish good from bad players, and yet we still see that disadvantages persist," he said.
"There are underlying structural and organizational processes at work that can undermine even the best efforts to objectively measure performance."

TROY, N.Y. -- Envisioning an animal-free drug supply, scientists have -- for the first time -- reprogrammed a common bacterium to make a designer polysaccharide molecule used in pharmaceuticals and nutraceuticals. Published today in Nature Communications, the researchers modified E. coli to produce chondroitin sulfate, a drug best known as a dietary supplement to treat arthritis that is currently sourced from cow trachea.
Genetically engineered E. coli is used to make a long list of medicinal proteins, but it took years to coax the bacteria into producing even ...
Tokyo, Japan - Humans are largely omnivores, and meat in various forms has always featured in the diet of most cultures. However, with the increasing population and pressure on the environment, traditional methods of meeting this fundamental food requirement are likely to fall short. Now, researchers at the University of Tokyo report innovative biofabrication of bovine muscle tissue in the laboratory that may help meet escalating future demands for dietary meat.
With global urbanization, the economics of animal husbandry are becoming unsustainable. From an environmental viewpoint, the land and water costs of modern mega-scale ...
In a world first, an international team of researchers has read an unopened letter from Renaissance Europe - without breaking its seal or damaging it in any way.
The research, published in Nature Communications, describes how an X-ray scanner used in dental research and 'virtual unfolding' allowed the interdisciplinary team to read the contents of a securely and intricately folded letter which has remained unopened for 300 years, while preserving its valuable physical evidence.
A highly sensitive X-ray microtomography scanner, developed at ...
A volcanic eruption in the Galápagos Islands has given scientists a fresh insight into how volcanoes behave and provided vital information that will help to predict future hazards on the islands.
Irish scientists, based at Dublin Institute for Advanced Studies (DIAS) and Trinity College Dublin respectively, were members of an international research team from Ireland, United Kingdom, United States, France and Ecuador that made the discovery.
The research published today (02.03.21) in Nature Communications reveals the first ever detailed description of a volcanic eruption from Sierra Negra - one ...
Hours before the 2018 eruption of Sierra Negra, the Galápagos Islands' largest volcano, an earthquake rumbled and raised the ground more than 6 feet in an instant. The event, which triggered the eruption, was captured in rare detail by an international team of scientists, who said it offers new insights into one of the world's most active volcanoes.
"The power of this study is that it's one of the first times we've been able to see a full eruptive cycle in this detail at almost any volcano," said Peter La Femina, associate professor of geosciences ...
A large proportion of the benefit that a person gets from taking a real drug or receiving a treatment to alleviate pain is due to an individual's mindset, not to the drug itself. Understanding the neural mechanisms driving this placebo effect has been a longstanding question. A meta-analysis published in Nature Communications finds that placebo treatments to reduce pain, known as placebo analgesia, reduce pain-related activity in multiple areas of the brain.
Previous studies of this kind have relied on small-scale studies, so until now, researchers did not know if the neural mechanisms underlying ...
In June 2019, an international team brought the complete skull of the 3.67-million-year-old Little Foot Australopithecus skeleton, from South Africa to the UK and achieved unprecedented imaging resolution of its bony structures and dentition in an X-ray synchrotron-based investigation at the UK's national synchrotron, Diamond Light Source. The X-ray work is highlighted in a new paper in e-Life, published today (2nd March 2021) focusing on the inner craniodental features of Little Foot. The remarkable completeness and great age of the Little Foot skeleton makes it a crucially important ...
Publishing in peer-reviewed scientific journals is crucial for the development of a researcher's career. The scientists that publish the most often in the most prestigious journals generally acquire greater renown, as well as higher responsibilities. However, a team involving two CNRS researchers* has just shown that the vast majority of scientific articles in the fields of ecology and conservation biology are authored by men working in a few Western countries. They represent 90% of the 1,051 authors that have published the most frequently in the 13 major scientific journals in the field since 1945. ...

Charlottesville, VA (March 2, 2021). Researchers in the Perelman School of Medicine at the University of Pennsylvania conducted a prospective cohort study utilizing their technique of delayed near-infrared imaging with high-dose indocyanine green (called "second window ICG" or "SWIG") in the identification of brain metastases during surgery. In this study, all metastatic lesions enhanced under near-infrared light with application of SWIG. The researchers compared near-infrared SWIG images obtained at the end of tumor resection with postoperative gadolinium-enhanced MRIs, considered the gold standard for imaging. The comparison demonstrated that SWIG can be used to predict the extent of gross-total resection and, ...
