Extreme Cynicism Equals Extreme Gullibility

How do you con someone to support you, either by them giving you their money, their vote, or adopting your cause?  I would answer, after having witnessed numerous examples of successful confidence schemes in the media, marketplace, and politics over the years, that first you need to establish that whatever you're promoting is outside the realm of the "establishment"...the forces that be per se...and that "they" not only cannot be trusted, but also are in opposition to your own agenda...which of course is only for the greater good and "truth".  This goes for selling alternative health food/supplements, claims about alien abductions/Roswell/chemtrails/bigfoot/ancient aliens/etcetera, denial of established science about evolution, ecology, and/or climatology, conspiracy theories such as Truthers, Birthers, and those with an anti-Semitic foundation, historical revisionism....and what the current president-elect, a fixture of the financial elite establishment for decades, has managed to accomplish by identifying himself as coming from "outside" that establishment in favor for the ordinary citizen.  To be suckered into following any of the aforementioned requires in advance a cynical rejection of established norms and an accompanying uncritical gullibility in favor of alternatives...as far-fetched and distant from believability and accountability as they may be...

I might also add that this cynicism/gullibility dualism is not just a phenomenon of America or the Western world.  I see this in the Islamic culture as well, where some people raised in the Muslim faith will cynically reject the well-developed, stable social structure within that society in favor of jumping uncritically into violent Jihadism, meekly buying into whatever lies their new masters tell them.  So cynicism and gullibility going hand-in-hand is not culture-centered...it probably spans all of humanity.  But I never hear anyone discussing it...what do you think?
