How does the AI distinguish fact from fiction?

Whoever decided to add "political bias" as a determining factor will lean people TOWARDS propaganda. To be clear; a fact is that cookies are made with eggs, flour and sugar (not complete list) bias is the opinion of liking or disliking cookies.

IOW, bias and accuracy are separate concepts. It has no bearing in sorting fact from fiction.

No matter how well trained the AI is, it cannot possibly deliver what is promised. Only provide information that makes it APPEAR to deliver on the promise.
