New Word: Doubtiness

Judging from the current political climate of the United States, I have determined the need for a new word.  The word is "doubtiness". It works the same as the word "truthiness" coined by Stephen Colbert but in reverse.

Doubtiness: Doubting something is true, no matter how much logic and proof is shown, because it just "feels" untrue.

Example: Birthers and Climate Change Deniers.
