Preface: This scale is meant as a jumping-off point for discussion. Please feel free to critique or make your own list. It is my hope that, one day, there will be a definitive list achieved through collaboration.
“Nerdy” is a term bandied about, willie nillie, affixed to many things. My intent is to establish a definitive list of nerdiness.
Is Spaceballs as nerdy as Firefly? Is Spaceballs as nerdy as Star Wars? No, it is not. So, we will take Spaceballs to be our baseline. All items will be measured in Spaceballs (SB).
The main facet of our measurement is level of divorcedness from Reality. For example:
aliens > (Cylons > androids >) robots > spaceships
So Star Trek is nerdier than Battlestar Galactica which is nerdier than Firefly
0 SB: Sports
0.01 SB: "Hans Solo? Isn't he that guy from Star Track?" THIS CAUSES NERDS TO DIE.
0.1 SB: Harry Potter
1 SB: Spaceballs
1.1 SB: Ghostbusters
2 SB: Jeopardy.
2.5 SB: Twilight Zone
3 SB: Star Wars
3.5 SB: Futurama.
4 SB: Firefly
4.5 SB: Star Trek VOY,
5 SB: Sar Trek TOS,
6 SB: Battlestar Galactica
7 SB: Star Trek TNG/DS9

This, sadly, is where my expertise in nerddom ends. I wanted the list to go to ten, but alas, I am uninspired and unknowledgeable past here. FAIL.
