You should always assume you might be being lied to.
Today, with the internet, you can only blame your own laziness for being fooled. The truth is out there if you care dig for it. It usually isn’t pristine, you'll might have to wipe the dirt off and there may be stains from being reproduced, but it’s there.
And there are biases everywhere. You can easily find them in Wikipedia and Snopes of all places. I don’t care how “intellectually honest†you are, you’re going to do some cherry picking of your numbers. That’s why people here used to get off their asses to show with citation, (not declaration and dismissal) where someone was wrong.
