This is Scientific American's 60-second science. I'm Christopher in Taliatta.

If you attend science conferences, ever pay attention to who in the audience ask questions?

Geneticist Natalie Tellis did, and she noticed something off.

The entire first day of the conference, I was the only woman to ask a question.

And I thought, wow, that's kind of weird, right? So being a scientist, she decided to systematically study who asked questions at

scientific conferences. Together with colleagues at Stanford University, where she was based at the time,

and others at Emory University in Atlanta, she recorded more than 2,000 questions from hundreds

of talks at eight different scientific conferences. After assigning either male or female

designations to question askers, which the researchers acknowledge in the paper doesn't fully

capture the spectrum of gender identity, they found that women ask far fewer questions than a

representative result based

on their numbers. In fact, you need about 85 to 90% of your room to be women before 50%

of your questions come from women. But Tellis did identify a possible solution. Halfway through

the Biology of Genomes conference in 2015, TELUS started

tweeting some of her preliminary findings about how few women had been asking questions

compared to their relative numbers at the meeting. That information sparked a public discussion

and a policy change from the conference organizers, who instituted a new rule that the first
