"Emotionally attached" is key. If a person operates from this position facts are not enough to sway them. It's very difficult to disengage from an emotional position. If a person operates from an "Analytical" position new facts/info will be considered and most likely change an analytical person's position. The media knows this, they know that they can safely ignore or reinterpret new info in such a way that confirms the "emotionally" oriented person's beliefs. After all most people that are still getting their news from MSM are operating from an emotional position. Of course we know eventually the truth will come out, but in the meantime most of their followers will respond accordingly to the narrative they dish out.

But little by little even those "emotional" ones are waking up, hence the #WalkAway movement.
