One of the four rebuttals fed the facial morphology of three species of monkey (grivets, crab-eating macaques and tufted capuchins) into Joel's methodological model and found that only 1 to 5% of the individuals' faces were "internally consistent" with those of their species. 

Her methodology couldn't even identify a tufted capuchin as a tufted capuchin more than 5% of the time. I doubt it could differentiate a tortoise from a teacup. In other words, it was designed specifically to avoid detecting what it was ostensibly seeking to find: patterns consistent with male brains and female brains.
