Absolutely tons of false positives, but the bar is set very very high for me to actively voice my support or share information. That might even be the more important skill because of shear volume of information being generated and shared across the world. Very rarely do I voice my disagreement with stories or ideas, not supporting or sharing them seems to be good enough. Very few things are true/false, most knowledge is drifting around on an infinite scale between [0,1.0].
