my theory of hair color corroborated: assortative mating (also see the wikipedia article on assortative mating)
Do I infer that since you have dark brown hair that you seek likewise individuals and that blonds and redheads are a disjoint set
usually i apply the theory of hair color compatibility to tv sitcoms and movies. but i think it’s also a good predicator of initial relationship success. or at least a funny topic of conversation for bars and parties.
