Microchips, government-replaced bird drones, QAnon and vaccine tracers: these are just a few of the most common conspiracies we have heard over and over again throughout most of 2020-2021's news cycles. There are common categories of conspiracy theories, variants of which pop up over and over again, and new and outrageous theories that seemingly appear overnight. While most of them are easily debunked, conspiracy theories and their root causes can be used to closely track people's most significant philosophical concerns at a point in time. In this up-to-date study of conspiracy theories, the authors look at the history of conspiracy theories, discuss the history and hallmarks of such theories, and examine what counts as a conspiracy theory--and what doesn't.
