听Gender bias can be beaten, 彩民宝典 researchers found in research with far-reaching applications.
听Researchers looked at several years of applications for time on the Hubble Telescope, finding male-led projects were historically overrepresented.
听When all personal data was removed from project proposals, women performed better than men.

The (HST) is helping find new ways to combat gender bias, according to new research from the 彩民宝典鈥檚 .
Stefanie K. Johnson, associate professor at the Leeds School of Business, worked with coauthor Jessica F. Kirk, assistant professor at the University of Memphis, to analyze 16 application cycles for time on HST. Johnson and Kirk can nearly eliminate gender bias from application processes, likely across industries beyond science.
The committee in charge of granting time on the telescope approached Johnson back in 2016. The Hubble Space Telescope Time Allocation Committee (HST TAC) was looking for ways to level out the acceptance rate between male lead scientists and female lead scientists who proposed projects using the telescope.
The cycles Johnson and Kirk analyzed had 15,545 applications. Among those, only 3,533 proposals had a female lead scientist. Male lead scientists had an acceptance rate of 23%. Female lead scientists had an acceptance rate of 19%.听
鈥淭he director of the Space Telescope Science Institute was looking for a solution to that gender gap,鈥� Johnson said. 鈥淥ur business research background was a perfect fit for finding insights.鈥�
Dual-anonymization
Johnson and Kirk found male reviewers in HST TAC were rating female scientists鈥� proposals significantly worse than male-led proposals.
From the 2013 to 2018, the committee tested several methods of masking the gender of lead scientists, including taking scientists鈥� names off of the front page of the proposal, using a first initial instead of a full name and listing all scientists on a proposal in alphabetical order to hide the lead scientist.
Finally, all scientists鈥� information was removed, and applicants were instructed to write their proposals in a way that would make it difficult for the committee to know who wrote it. This is known as 鈥渄ual-anonymization.鈥�
Female lead scientists performed slightly better than men when the proposals were completely anonymized. Johnson and Kirk found reviewers rated male and female lead scientist鈥檚 projects equally well鈥攎eaning dual-anonymization eliminated the gender bias.
鈥淵ou鈥檙e making the fairest decision based on the science,鈥� Johnson said. 鈥淚t鈥檚 not proof that women will always do better, but hopefully the gender balance will be closer than in years past.鈥�
Johnson said companies and organizations have been using dual-anonymization for decades, but the idea has gained visibility since the launch of the women鈥檚 movement in 2016. Johnson believes the data from her new study shows dual-anonymization could work for nearly any group looking to combat gender bias, not just telescope projects.
鈥淯ntil now, there hasn鈥檛 been a lot of data on whether it works or not,鈥� said Johnson. 鈥淲hat this shows is that taking gender out of the equation does allow women to perform better.鈥�
