Believing in Conspiracy theories is a part of an Extreme Victim Mentality

 It's important to understand this in the first place. Why do people believe in Crazy Conspiracy theories?

Mostly because these people have either been seriously victimized in their lives or they believe they have been seriously victimized during their lives. And Believing in Conspiracy theories is a way to cope with one's victimizations that they don't have any useful way of dealing with.

Also, people like this often would NEVER go see a counselor like an MFT or Psychologist or Psychiatrist 

simply because their friends and relatives might think them crazy for doing so. It's a little like Police and Firemen and soldiers constantly lie to psychologists after serious things happen that WILL cause PTSD because they don't want to lose their jobs.

This is the main reason by the way that cops shoot black men in the back, PTSD. In other words all police lie to keep their jobs even if they are waylaid by horrible experiences where they see dead people or maimed people all the time in their jobs.

So, people like this are often blue collar people who have never been to college and learned Critical thinking or if they have it has been undermined by PTSD causing experiences.
