Question: Conspiracy Theorists, in *my* opinion, are people I don't like except for some exceptions. However, this question will not be answered with my irrelevant opinions on said people..

Now, here is the question:

* Why do conspiracy theorists become conspiracy theorists?
* Why do they get the ideas that they do?
* Are they looking for attention?
* What are the mechanics behind their minds/thought process?

Some conspiracies:

* "Tupac is still alive, he will come back in year 20(12,13,14)"
* "The New World Order is going to take over the world."

Do these people warp things like the Illuminati into a conspiracy? What is behind the minds of these people? Is there any prevalence of mental (conditions, disease) among them? Is there any different type of parenting or environment they are raised in?

All of these questions don't need to be answered, but those are the questions running through my mind.

Answer: 
Interesting question, I am glad that you stated that it is not going to be opinion-based (grounds for closure), as there is some research being done in this field.

A couple papers and details of their research for you:

["Social Psychological Origins of Conspiracy Theories: The Case of the Jewish Conspiracy Theory in Malaysia"](http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3412387/) (Swami, 2012) states that in some cases, such as the case study presented in the title of this article, it is a 'state-based' conspiracy theory, where:

> 
> in which state-directed conspiracism as a means of dealing with **perceived** external and internal threats
> 
> 
> 

(emphasis mine).

This could also be extended to why individuals take on the conspiracy theories themselves.

This, in a way relates to the next article:

["The Sarrazin effect: the presence of absurd statements in conspiracy theories makes
canonical information less plausible"](http://www.experimental-psychology.de/ccc/docs/pubs/RaabAuerOrtliebCarbon_inpress.pdf) (Raab et al. 2013), which is best summed up in one of their concluding paragraphs:

> 
> It is these dynamics of reception, alteration and propagation that account for the many-faceted
>  phenomenon we call conspiracy theory. The cognitive effort, i.e., considering information in
>  the eventuality space, might be rewarding and satisfying in itself; just like an aesthetic

Essentially, it is almost like the first example, where the state propagates a conspiracy theory to try to comprehend and cope with perceived threats, the same can apply to the individual.

I hope this helps.
In my opinion the main reason of conspiracy theory is lack of information. As in rumors.
In this wikipedia page you can find a lot of research on rumors:
<http://en.wikipedia.org/wiki/Rumor>. When people dont have enough information they tend to confabulate because of Gestalt princioles.

But also there is quality of conspiracy theory and amount of truth, not all conspiraci theories are bogus.
