If this was a conversation about whether a new drug worked, the conversation would be over.
In fact given that the article we're allegedly discussing is about how there is no pay gap in tech, there's reason to think that this sort of outcome may not apply across the board.
1 - more roleplay
2 - perceptions of women in management, says nothing about earnings, concludes people may actually prefer female managers.
3 - Says women who alter their behaviour in certain ways actually do better than men.
I'm not sure of the point you were trying to make, but they don't seem to support the idea that women are actively penalised for negotiating out in the real world.
