Over the last several years, conspiracy theories have drawn increasing media attention. From birtherism to QAnon, from pandemic disinformation to lies about the outcome of democratic elections, conspiracy theories have been openly embraced by politicians who seek to use them to influence the electorate.

But, first of all, I will provide a definition of the term conspiracy theory in order to avoid ambiguity and confusion. "Stop The New World Order" by Christian Cable, lic
