The condition of having a short, broad skull, or the state of being brachycephalic; a measure of skull proportions.
From Greek brachys (short) + kephalē (head) + -y (suffix forming nouns), the base term for this cranial characteristic.
Brachycephaly was the hot scientific obsession of the 1800s, but turned out to be a natural human variation with no meaningful connection to intelligence or ability—a cautionary tale of how science can create authority for bad ideas.
