I'll never forget my junior year in college when a course called, "The Exceptional Child," was part of our curriculum. Of course, "exception" ran the spectrum to studying the child with developmental difficulties all the way to the gifted child (the latter, an area of study that had previously been ignored). The chapter on the gifted child and the professor's lecture was fascinating. "Back in the day" the stereotype of the gifted child was that this child was most likely very inept at sports and other such activities. The statistic that I remember from that class is that when you are gifted, often you are gifted across the board. Thus the child who is consistently stellar on the football field or volleyball court is also gifted in the classroom.
My favorite, favorite, favorite show, "The Big Bang Theory," of course, plays out your example loud and clear in the character of Penny, and on the flipside with the guys. J)ohnny Galecki and Simon Helberg are certainly no Ryan Goslings although Simon Helberg does have amazing eyes.)
It's been my observation, having been always attracted to really smart men in my youth, that the stereotype is definitely wrong. Initially I had been attracted to these men because of their looks or how they moved, only LATER to find out that they were really, really smart - one a nuclear engineer, 2 electronic engineers, and 1 a software programmer.
Of course the use of the term "ugly" is never appropriate, and it's important to realize that standards for physical beauty are cultural and change with the time. Many women and men who are in the movies now and considered "beautiful people" would NEVER be considered in the 20s when beauty meant symmetry of the face, high cheek bones, and other criteria. And lips plumped up with Botox? People would have thought that a sad condition that one had to endure.
No matter what, it is clear that beauty emanates from the inside. Whether intelligent or not, a person is perceived as beautiful if they are truly centered, and if they are genuinely unselfish, thinking more of the person they are talking to than of themselves. A person is perceived as intelligent if their grammar and vocabulary are correct, if they are well-read, and if they make logical arguments. Intelligence is also a nebulous concept and has a huge number of facets as Guillford's Cube of Intelligence indicates.
So, all in all,only one thing is clear - no one likes to be thown in the box labled "stereotype."
