New readers keep asking what HBD means. As I recently defined NAM, I take this opportunity to define human biodiversity.
Human biodiversity is a superset of race realism, which I defined in my blog post, an essay on race and intelligence.
Human biodiversity is an acknowledgment that humans differ from each other in various ways because of our different genotypes. Differences include, but are not limited to, physical appearance, athletic ability, personality, and cognitive abilities.
One especially significant genetic difference between humans is whether or not they have one X and one Y chromosome or two X chromosomes. In addition to looking different, humans with two X chromosomes have different behavioral and cognitive predispositions than humans with one Y and one X chromosome.
Even when humans are of the same race and sex, they can have vastly different cognitive and behavioral predispositions. This is also part of HBD.
HBD is the better term to use than “race realism,” even when the discussion is limited to that subset of HBD, because “race realism” sounds vaguely racist and everyone knows that racism is the most evil thing which exists in the world. HBD, on the other hand, sounds vaguely like “diversity,” which everyone knows is the most beneficent and blessed thing which exists in the world. People can celebrate human biodiversity, but no one will ever celebrate race realism.
