Why are conspiracy theories so appealing to otherwise intelligent and informed individuals? Sometimes the answer to that is because everything can be cast in clear light to some people. Can there be no more grey areas and there will only be contrast of black and white, right and wrong, or truth and lies? There's simply no great neccessity to understand the complexities of western foreign policy or the roots of Islamic fundamentalism when clear-cut ideological motivations are invented.
Sadly, this world isnt simple. It is more like a web of interconnections. With so much going on and so little time to take it all in by its reality and the media, it can be shocking to try comprehending it all. This in the very core is where conspiracy theories fit in. It simply means that there is no need to comprehend when one can simply explain away .
It is also about power. Conspiracies can be made easily to make people feel subsumed by economoic realities, political systems or social conventions far beyond our control and thus leaving many of us feeling completely powerless. Through gaining knowledge, not given by the media nor available to the public, one can create his own power. Like those who carry out these conspiracies that the average truth seeker wants to uncover, it makes one feel his own elite- the privileged few who have access to the truth. It automatically makes a person feel better than the ignorant and uninformed masses that thrive on the sense of superiority .
One may imagine, does it really sound that bad? I guess, with a conspiracy theory on your side, everything can be made simple and this can instantly make you become better than everyone else in a matter of uttering a few words.
