Let's face it the ONLY thing they care about is ratings. 2) no one in the world has the facilities or the interest to check up on every fact in a documentary. Because we all know you can find experts to disagree on every single thing. So just for laughs let's assume that someone is making a documentary about Egyptian heiroglyphics. They start with ubiquitous Nefer symbol. The producers hear that the nfr. symbol is the heart and lungs. But they decide to fact check a little further and find out that there are two other opinions on what the Nfr. symbol one says it's a 'boat oar' and another group thinks it's a musical instrument. So who do they go with? Who's right and who's wrong? Then something happens the producers 2'nd cousin who's backing the venture, tells them that it's actually a spoon. Well we know the 'spoon' thesis is making it into the movie for an absolute fact, but what else? So we make the movie knowing that it's going to be scrutinized by the board of fact checking. So they play it safe. The announcer says "The nfr symbol could be the heart and lungs of a man, or a boat oar, or a musical instrument, though there are some who think that it could be the pharaoh's spoon. Next up the ntr symbol. Some people think it's a flag others that it's an axe, others think that its the flag on a mailbox." It's fair, even handed, presents all sides and is about as interesting as reading a shopping list. And except for the handful of Egyptophiles watching it everybody else has changed channels to watch "Dancing with the Stars."
