SAN FRANCISCO --A new report shows that Uber and Lyft drivers are profiling black passengers.
The research by M.I.T, Standford and the University of Washington shows that a passengers' race could determine how long a passenger waits for a ride.
"When the passengers used an African-American sounding name, they were canceled, the ride was canceled more than twice as frequently," explained Stephen Zoepf, with Stanford Center for Automotive Research.
Researchers found that black passengers waited between 29 and 35 percent longer than white passengers. They also found that drivers routinely took women on longer-than-necessary rides.
Researchers sent assistants into the field in Boston and Seattle to request rides from Uber and Lyft. They say they found discrimination in cancellations and wait times.
The study included almost 1,500 rides. Four black and four white research assistants-split evenly among men and women-ordered cars over six weeks in Seattle. All used their photos on the ride-sharing apps.
A second test was held in Boston with riders "whose appearance allowed them to plausibly travel as a passenger of either race," although they used either "African American sounding" or "white sounding" names, the researchers said.
The study found that Uber drivers disproportionately canceled on riders with black-sounding names, even though the company penalizes drivers who cancel frequently.
A statement from Uber reads in part: "We believe Uber is helping reduce transportation inequalities across the board."
Lyft issued a similar statement: "We are extremely proud of the positive impact Lyft has had on communities of color."
It's worth noting, Uber drivers have to accept a fare before they see the name of the passenger.
Lyft drivers see the name immediately.
"Our concern was that peer transportation systems weren't eliminating discrimination, but they might just be hiding it," said Zoepf.
Some suggested remedies from researchers is to not use names at all and to conduct periodic audits of drivers whose behavior appears discriminatory.
