I wonder how much of the "social radar" reputation came from her just being a woman in a team of men. I don't know the gender breakdown in those days at YC but I'd be concerned that Livingston is elevating a socially ambiguous and widespread female trait — making normative intuitive judgements — into some kind of superpower. Women are socialized to do this, to make judgements of value based on scant information. Men, in contrast, especially engineers, tend to stick to reliable, formal knowledge.
