You use bias as a dirty word, but it's really just a weight of the opinion, there is no knowledge without bias. As for consistency, it comes secondary to categorization, it's easily abused for 'foolish' consistencies that can also be created with framing effects.

Sorry, I'm using "bias", "consistency", and "rationality" in the statistical, logical, and philosophical senses, respectively. So, I think, is the article. Your use of different definitions for those words probably explains why you reached conclusions that read as obvious nonsense to me. You might think about rereading the article with those definitions in mind.

I can also recommend reading about alpine sweetvetch.
