Similar to the beer goggles effect, a person which one would not find typically attractive is seen as attractive. This effect is a cause of the UC Berkeley bubble, where a lesser amount of typically attractive people exist. Another factor included is the envelopment of academia connected to a decline in one's social life.
Me: At first I didn't think (insert name here) was so cute, but there is something different about them this semester.
Friend: Looks like you're sporting the Berkeley goggles now. You've been in the Berkeley bubble too long. At least your option has a good personality.
When you first arrive in Berkeley, you don't think the people are very attractive, but as you notice how crappy the city is, you start to think that a 6 is 9, and then you find it even easier to hook up with people since outsiders look real good to them.
