How are the scores determined?

To determine a person's score I assign the following bullshit value to each ruling type:

True = 0% full of shit
Mostly True = 25% full of shit
Half True = 50% full of shit
Mostly False = 75% full of shit
False = 100% full of shit
Pants On Fire = 200% full of shit

I then add all of their scores together and divide by the total number of rulings, easy as pie!

Due to the extreme untruthfulness of a Pants On Fire statement each one not only counts as a falsehood but also annihilates a truthful rating as well, making it possible for certain habitual liars to score over 100% full of shit.
