//Machiavellianism is a female instinct and a male art form.//

//For women, absent of physical prowess, Machiavellianism was nature’s way of ensuring their continued survival.//

//Women on the other hand are Machiavellian as water is wet. You’d be hard pressed to find a woman who isn’t Machiavellian.//

I have been searching for evidence on this issue since this article does not have citations in it. So far the evidence I have gathered suggests the opposite. I hope anyone here could give me relevant sources to back this claim up. The following quotes were the contradicting evidence I've found:

//The most pronounced group difference is in sex: numerous studies have shown that men tend to score higher than woman on narcissism,[57] Machiavellianism,[58][59][60] and psychopathy,[33][34][61][62] although the magnitude of the difference varies across traits and the measurement instruments used. One interesting finding related to narcissism—albeit one based on non-representative samples—is that while men continue to score higher than women, it seems that the gender gap has shrunk considerably when comparing cohort data from 1992 and 2006. More specifically, the aforementioned findings indicate that there has been a general increase in levels of narcissism over time among college students of both sexes, but comparatively, the average level of narcissism in women has increased more than the average level of narcissism in men.[63]//

//Measured on the Mach - IV scale, males are, on average, slightly more Machiavellian than females.[9][11]//
