One expects built-in counter-biases where challenges are put to prevailing biases -- particularly when the challenger is the academic establishment, and the challenged is the establishment's fevered vision of what it thinks the academic establishment really is.
And we all know that what it really is is systemically biased against women. "Biased," in this case, means not rigged to produce a certain robust outcome: "more" women scientists and engineers. How much more? And why that particular amount? Silence! Bow thy head and ponder the vast evil of such institutional phenomena as this, propounded by the Panel Report of the National Academy of the Sciences: "anyone lacking the work and family support traditionally provided by a 'wife' is at a serious disadvantage."
