A conspiracy theory is a story. Stories are created through a selection process: selecting what fits the story-line and ignoring what does not.
Conspiracy theorists believes their own stories and that is the problem. Instead of the most plausible explanation, they settle for the one which best fits the pre-existing narrative. This cognitive bias is what leads the conspiracy believer down the rabbit trail slippy slope path of harmful misinformation.
Those of us who deconstruct stories, both mainstream media and alternative media, are not conspiracy theorists. We aren't positing stories of our own. Instead, we are conspiracy analysts.
You can describe what we do as anti media. Conspiracy theorists are not antimedia; they are a subset of alternative media. The antimedia breakdown of MSM lies is the opposite of storytelling. It would be better described as story-untelling.
