Metta World Peace -- Girls Are Smarter than Boys

He coaches BOYS high school basketball ... and GIRLS high school basketball ... and when it comes to brains, Metta World Peace says it's all about the XX chromosomes.

MWP is an assistant coach for both teams at Palisades Charter High School in Los Angeles -- and says he LOVES being able to pass on his basketball knowledge to the kids.

But when it comes to absorbing that knowledge ... Metta says it's become perfectly clear -- the women are just smarter.
