I really can't understand why they didn't take into account the cultural bias tided to the different races. I would guess that Asian people are looking for different values in their partners than Caucasians. And even if I were wrong, I don't think that they should dismiss that proposition without even checking, or citing a relevant paper on the subject.

No. UBC is known, at least in British Columbia, for having an abnormally large percentage of Asians relative to other ethic groups.

In BC? Yes it is.
