I agree that that qualification suggests his view on the contribution of biology to the gender gap is weaker than his otherwise definitive framings suggest. [Edit: Sentence here removed because I’m too tired and my thoughts are not in order, will get sleep before responding to any more comments. Replacement: He’s still presenting it as a black-and-white issue if he’s only presenting one side.]
Google may have had that conversation on prejudice going, but he is very oversimplistic and offers the essentialist view as so definitive that his solutions are the right ones, that Google is the “biased” party for talking about prejudice, and that it isn’t worth even mentioning that evidence demonstrating a bias against women exists (if he even knows or believes that), not to mention that the evidence for the real-world effect of prejudice is far more vast and robust than his evidence for biological causes. And he does all this when the essentialist view has been so dominant and people are only talking so much about prejudice because they’re trying to overcome the essentialist thinking that so inhibits people. (Sure, there are differences, but there are even more misconceptions, as well as oversimplistic and deterministic assumptions about what real differences mean.)
[Edit for clarification and additional analysis: In a context of prejudice, presenting stereotypes is a delicate matter even if you think them sufficiently biologically valid and are content to make simplistic inferences about their real-world effects. Doing so without acknowledgement of the prejudices people experience which line up with these stereotypes and which harm them serves to reinforce those stereotypes and prejudices.]
So it’s not an appropriate way to contribute to the conversation—at best it’s reacting to perceived overshooting by retreating to a flawed status quo.
I see, we’re just thinking of “combative” differently.
