<p>Because numbers are physcological - a way to measure people's intelligence. I agree it's wrong and all that jazz, but think about it. If one person walks up to you and tells you he has a 2400 and another comes over and says he has a 1700, which are you going to automatically assume, if you don't know either, is the more intelligent? </p>
<p>Anyways - yes, all forms of education love tests...</p>
