I hear this on NPR this morning and thought it was interesting.
They do note that negotiating can backfire more for women but they don't say whether that is in how women tend to negotiate or a bias and they don't say how much that hurts a women's chances at getting the job
It seems some companies view the way to fix this is to prevent anyone from negotiating a better salary like Reddit has done

When it comes to negotiating salaries, the research is pretty clear: women are less assertive than men. It's one reason women who start their careers with a narrower pay gap see it widen over time.
Carnegie Mellon economics professor Linda Babcock, who studies the gender pay gap, says men are four times more likely to negotiate their pay. That keeps women at a disadvantage, though they're not always aware of it.
"The standard now is that people don't really know what each other earns, that some people negotiate and some people don't, and so there's tremendous inequities in salary," Babcock says.
Many people leapfrog into higher salaries when they switch jobs. But Babcock says the pay disadvantage follows women if their new employers use their old salaries as benchmarks, as is often done.
