You can apply evolution and meme models to it. Every piece of info on Twitter is an idea fighting for survival. You'd think having 'fact' as a property of a tweet would be beneficial. But it's the opposite- the truth is often unpleasant and people don't want to hear it. This gives 'factual' tweets a survival disadvantage on Twitter. If a fake tweet makes people 'happy' (by way of confirming their innate belief), by evolution they'd out-compete other tweets.
