The reason I find it gratifying — far more so than I should, I'm sure — is that I am primarily a mathematical and scientific based person. In the comparison between mathematical and verbal reasoning skills, my verbal reasoning skills tend to get left behind.
I generally tend to think that I actually have very good verbal intelligence, but it's just that my mathematical side is even better. One is that due to my scientific vocation, I tend to have a dreadful lack of knowledge when it comes to the other side of things. The other is that I hang out with wonderfully intelligent people, which makes taking a baseline comparison rather more difficult.
As such, it's most gratifying that I can score 49 out of a possible 50 on a vocabulary test. Yes, I'm well aware that it's almost but not quite entirely meaningless, but I'm still feeling smug over it.
