mobsense 

Mob + (lack of common) Sense. Foolish mob-mentality/group-think. The educational system, social media, and the mainstream media are responsible for creating mobsense people. The masses are perfect examples of Mobsensical people, they lack common sense and follow group-thinking and mob-rule; and they are often detrimental to civilizational preservation and stability.

"From my college class to CNN, I am surrounded by a lot of mobsense."

"Sounds like a lot of mobsense to me!"
