There’s new software that proves what we’ve believed all along: Female actresses don’t get as much time on the big screen as their male counterparts. The tool is called the Geena Davis Inclusion Quotient (GD-IQ), named after the actress famous for Thelma & Louise and A League of Their Own. Davis is a proponent of fair gender representation on screen.

GD-IQ can analyze a 90-minute film in 15 minutes. That job takes longer when humans do it. The automated software quickly and accurately combs through every line and scene in order to calculate how much time a female character is on screen and how often she speaks compared to male characters.

The software was developed by the Geena Davis Institute on Gender in Media at Mount Saint Mary’s University in Los Angeles, and funded by Google.org. Researchers combined audio-visual processing technologies with Google’s machine learning technology to develop GD-IQ.

Watch our video to find out what researchers learned after running the 100 top-grossing films from 2015 through the software.

Correction: An earlier version of this article said the Geena Davis Institute on Gender in Media is based in Emmitsburg, Maryland instead of Los Angeles.
