The term conspiracy theory was created by the FBI and pushed through the media during the cold war to discredit people who questioned things like the JFK assassination or discussed things like MK Ultra.

They muddy the waters by pushing angles like tinfoil protecting you from mind control rays so that if anyone questions the narrative they will be discredited by association. The most recent example of this is in Maui where they are pushing the angle that the government is using energy weapons to start the fire so that in the minds of normal people anyone bringing up that the government allowed it happen will be seen as mentally ill.
