(Black men must be rated better looking only because they aren't giving test subjects a full range to consider. And the ones who are mistakenly permitted to receive a blessing from deluded white women tend to have a white bone structure. That whole ape-like slack-jawed I'm-gonna-cut-choo appearance doesn't make the grade, apparently.)
Psychology would be fine, except that Jews insinuated themselves into it, wherein they deployed their model of sowing conflict and excessive word patterns, reducing objectivity. The early twentieth century saw a healthy push toward eugenic understanding, which included good ideas about raising children. Psychology is part of the current model, which results in denaturing and brainwashing.
Anyway, just saying yeah.
