Spectrum of theistic probability

http://en.wikipedia.org/wiki/Spectrum_of_theistic_probability

This is a very useful tool in identifying your own position about God's existence. It breaks away from the idea that individuals are either theists or atheists. This gives more flexibility for people who aren't certain of both sides; it allows for the possibility that people many not feel one way or other about god's existence. The  positions made available by this scale is anything from De facto theist to De facto atheist.
