Absolutely.
We can acknowledge evidence, form plausible hypotheses, and point out possible inferences along with their caveats, of course. But no, we can’t draw firm conclusions about the relative effects of intertwined causal factors that we can’t meaningfully isolate from one another.
Why on earth would you imagine that we could? That’s like asking “Do you think we can read what’s written on the piece of paper sealed in this impermeable unbreakable unopenable opaque container?” No, we can’t, because we simply can’t access the crucial data.
What we can do is form some plausible hypotheses based on the evidence we do have surrounding the crucial data, of course. “Let’s see, we know that piece of paper came from Uncle Humphrey’s desk, and we can’t ask him about it because he’s dead, but we know he was very upset about the sprinkler malfunction, and he often liked to write letters to the newspapers about things he was upset about, though he was also very prolific with his shopping lists.”
There’s a hell of a lot of practical difference between “We can’t tell what’s written on the paper in the impermeable unbreakable unopenable opaque container, but it seems very likely that it was written by Uncle Humphrey, and if so it seems plausible that it was either a shopping list or a letter about the sprinkler malfunction” and “We are convinced that there cannot possibly be any writing at all on the paper in the impermeable unbreakable unopenable opaque container, because that sort of paper is incapable of being written upon”.
In terms of actual cast-iron certainty about the content of the writing, there may be no effective difference between the two positions. But I don’t think that any researcher would agree that there’s “little practical difference” between them.
I’m certainly not accusing you of advocating “race realist” positions, or similarly bigoted positions about gender, if that’s what you mean.
I’m just pointing out that you’re overstating the certainty of hypotheses about innate biological influences on gender differences, just as “race realists” overstate the certainty of hypotheses about innate biological influences on racial differences. And, ISTM, for fundamentally the same reason (minus the bigotry): You really want there to be definite concrete answers about exactly how, and how much, biology contributes to these phenomena, because you would like to know what the answers are. And you’re frustrated that those definite concrete answers simply don’t exist—not yet, and maybe not ever.
Yup, I’ve been doing that too, as have Riemann and other posters in the thread.
