manipulation

This is from an online guide to seeking consensus. It describes techniques for manipulating or hijacking a democratic process:

"Exhibiting stress, anxiety or grave worry is a common way for manipulators to exert influence, since most of us are conditioned to want to help someone in distress, and we may be so eager to do so that we will overlook other priorities just to ease the discomfort as quickly as possible. By appearing fretful at the possibility that something might not get done or put upon by having to do so much himself, a de-facto leader can galvanize people to act without attention to previously agreed-upon parameters. Similarly, acting hurt, shocked, or giving the appearance that one is seething with righteous indignation in the face of a concern that has been raised is a quick way to silence inconvenient dissent.

"The group's most common reaction to a faction or individual who seeks to sway the collective's will is not, as one would hope, calling the authoritarian manipulators to task, but gratitude that someone is taking on the difficult work of running the group and its activities. These members become complicit in the power-grabbing tactics of the self-appointed leader(s). Oftentimes, collective members actually offer these self-appointed elites their loyal support and become openly distrustful or disdainful of those who question the actions or authority of the leadership. At this point, the group is not only no longer operating collectively or by consensus, it has effectively become a private club."
