That's great if your network is informed and perfect, but will fail to pick up on new info, especially if you reject it on instinct. 

You don't have to use social heuristics for everything, you can read the info and judge for yourself, then you BECOME one of those people that people "pull" from.

Anyway, if you aren't interested it's okay, I'm just not here to humor any narratives meant to protect ignorance.
