Analysis of OWS Psychological Types Shows Rank and File To Be Lost Souls Looking To Lose Themselves In Something Bigger, and “Leadership” Animated By Need For Validation and Control
This is probably not surprising to you, so much as it is a sharpening of your gut-level vibe.
A group called “Frontier Lab” employed market-research type surveys, peering beyond surface-level questions that pollsters usually asks, to get at what really animates OWS.
First, that many of the rank-and-file occupiers feel isolated in their lives, and appear to lack basic community ties such as are provided by participation in clubs, churches, and strong families…. They thus attach to their political causes with something like a religious fervor. For many, a commitment to “social justice” is “not the end, but rather a means to an inflated sense of self and purpose in their own lives.” Crucially, involvement with others who agree with them provides an “overwhelming feeling of being part of a family.” I noticed this on my first trip down to Zuccotti Park, when I saw a telling sign adorning the entrance to the tent city: “For the first time in my life, I feel at home.” On subsequent visits I was struck by the importance of the commune to the project. As much as anything else, vast swathes of occupiers were simply looking for a new club. This group, Frontier Lab dubs the “Communitarians.”
Hat tip: McCain, the Other Smitty 
We humans are social animals, and have a natural desire, indeed need to belong. We need to be part of something bigger. The left has waged relentless war on those very institutions that gave life meaning and structure. such as the family and the church. Now wayward souls are driven to join movements dedicated to public defecation Are you shocked?
