I have been curious about photoreading misinformation in books. What if an author just doesn't know what he is talking about and prints incorrect facts. Or a book contains half-baked theories or something. Will the subconscious just take all of that to be true or is it able to discern between good information and bad.

Also what if a book has a bunch of negative themes or limited thinking in it could that possibly effect a persons belief structure negatively?
