As mass formation progresses, the group becomes increasingly bonded and connected. Their field of attention is narrowed and they become unable to consider alternative points of view. Leaders of the movement are revered, unable to do no wrong.
Left unabated, a society under the spell of mass formation will support a totalitarian governance structure capable of otherwise unthinkable atrocities in order to maintain compliance. A note: mass formation is different from group think. There are easy ways to fix group think by just bringing in dissenting voices and making sure you give them platforms. It isn’t so easy with mass formation. Even when the narrative falls apart, cracks in the strategy clearly aren’t solving the issue, the hypnotized crowd can’t break free of the narrative. This is what appears to be happening now with COVID-19. The solution for those in control of the narrative is to produce bigger and bigger lies to prop up the solution. Those being controlled by mass formation no longer are able to use reason to break free of the group narrative.
