Yes:: They turned it into the WikiPEDIA version :

"A conspiracy theory is the fear of a non-existent conspiracy[2] or the unnecessary assumption of conspiracy when other explanations are more probable.[3] Evidence showing it to be false, or the absence of proof of the conspiracy, is interpreted by believers as evidence of its truth, thus insulating it from refutation.[4][5]"

I think some people actually think that convoluted way. :(
