Female Coders Are “More Competent” Than Males, According to a New Study

Add a new academic study to the growing body of evidence that gender bias is rampant in the world of computer programming.

Computer scientists from California Polytechnic State University and North Carolina State University gathered publicly available information about roughly four million GitHub users who logged in to the service on April 1, 2015. GitHub, a repository for programming code, doesn’t require that users reveal their gender, but the researchers were able to use other information and what they call a “novel gender-linking technique” to identify the gender of just over 35 percent of those users, or around 1.4 million.  

An analysis of pull requests, or users’ submissions of new code to the projects of other software developers, revealed that code written by women was accepted 78.6 percent of the time. For men, the figure was 74.6 percent. But when female coders did indicate their gender, they were far less likely to have their code accepted, with their approval rate plummeting to 62.5 percent.
