Skull/forehead Theory!

Hi ladies! Out of pure boredom on this Friday night, I'm reading up on gender wives tails. Just heard about the skull theory and supposedly its 92% accurate. According to this, boys have a more square shaped head and flat forehead- girls are suppose to have a more rounded head and pronounced forehead... Anyone familiar with this and wanna take a guess? I know it's hard to tell but this is just for entertainment šŸ’™šŸŽ€
