Sometimes I think the urge to believe in our own worldview is our most powerful intellectual imperative, the mind's equivalent of feeding, fighting, and fornicating. People will eagerly twist facts into wholly unrecognizable shapes to fit them into existing suppositions. They'll ignore the obvious, select the irrelevant, and spin it all into a tapestry of self-deception, solely to justify an idea, no matter how impoverished or self-destructive.
