The Probability of God Test.

Well worth doing as believer or atheist. It looks at your logic and it requires you to detach from 'taking the test based on previously held views'. Only takes a few minutes.

The Probability of God Test
This test asks you to answer 11 questions about God, the universe and people, and from these answers estimates the strength with which you believe that God exists, using an established probability calculation known as Bayesian probability. This test can't tell you the objective truth, but it can help you understand the implications of your personal opinions.

Take the test here. The shorter version is here.

 I took the shorter test and tried to detach myself entirely from all previous thinking and just move into a logical position.

The result was startling.
