At CMU, it is very important to become familiar with something called, "CMU goggles." Similar to beer goggles, the longer you wear your CMU goggles, the more attractive the campus becomes. Obviously, these are not literal "goggles"; however, the longer students are at CMU, the more frequent that a 5 or 6 in the outside world becomes an 8 or 9 (usually if people would describe someone as a 10, they really are—there's no hiding hotness like that). The reasons for these goggles are varied. Some would say it's because you get used to the people and decide that if you can't beat 'em, join 'em. However, most are pretty optimistic about their fellow students. CMU goggles exist for most students because they have just come to know the people behind the looks. Students agree that everyone here is driven, talented, and intelligent, and a large portion are truly friendly and outgoing—you'll find that the looks don't matter as much after a few years.
This is not to say that CMU is a campus of ogres. The typical response is that there are some hot guys and equally hot girls, but most of the campus is pretty average looking. It is probably because students would first describe themselves as "nerds" before describing themselves as "sexy" people. Assuming you've seen enough teen movies and TV shows, though, nerds aren't always that bad. Like any other campus, CMU has its fair share of people who turn heads in a not-so-good way. It is probably because these cape-wearing, vampire-teeth-donning, singing-out-loud-by-themselves students are just so far out of the norm, that CMU has garnered a reputation for weirdos. It's really not that bad—it is what makes CMU unique—and students will often conclude by telling you that there is someone for everyone.
