13. Negative Correlation Hypothesis Anthropologist Sara Blaffer Hrdy: “Female primates are just as competitive as male primates in that they seek status within their social order. So it would follow that women strive for status too. But there is a qualifier: When primates compete, they do so in ways that increase the survival chances of their offspring. In other words, they do it for their children. “At this moment in Western civilization,” Hrdy says, “seeking clout in a male world does not correlate with child well-being. Today, striving for status usually means leaving your children with an au pair who’s just there for a year, or in inadequate day care. “ “So it’s not that women aren’t competitive; it’s just that they don’t want to compete along the lines that are not compatible with their other goals.”
