Conspiracy Theories, Cults, & Crimes

In 2009, at a science fiction convention in Atlanta, a paranormal researcher named Fiona Broome discovered that strangers shared her vivid memory of Nelson Mandela dying in prison in the 1980s. Mandela walked free in 1990 and died in 2013. Broome named it the Mandela Effect, and the catalogue grew: a children's book spelled wrong, a logo with a horn that never existed, a Sinbad genie movie nobody made. Believers concluded that reality had been edited and their memories were souvenirs of a lost timeline. Then in 2022, University of Chicago researchers put the phenomenon in a lab, confirmed that huge numbers of strangers share the same specific false memories, and reported no clear explanation for why. In this episode of Conspiracy Theories, Cults, & Crimes, Vanessa examines the false memories millions of people share, the parallel-universe and CERN theories built to explain them, and the uncomfortable question underneath all of it: is it scarier to live in an edited universe or to have a mind that cannot be trusted?

Long before the name Jack the Ripper struck fear into Victorian England, a respectable-looking widow named Mary Ann Cotton was quietly killing her way through the north of the country. By the time investigators caught up with her in 1872, she had outlived four husbands, a lover, and eleven of her own children, nearly all of them poisoned with arsenic and many insured for cash. Hiding in plain sight behind the mask of a grieving mother and wife, she is now considered Britain's first known serial killer, and one of its most overlooked. In this episode of Conspiracy Theories, Cults, & Crimes, Vanessa Richardson uncovers the chilling story of Mary Ann Cotton, the string of deaths that followed her from town to town, and how a woman managed to murder on such a staggering scale for so long before anyone noticed.

In 1954, a housewife in Oak Park, Illinois named Dorothy Martin began taking down messages from beings she called the Guardians, and told the small circle around her that a flood would destroy the middle of North America before dawn on December 21st. Flying saucers would collect the believers first. The group, who called themselves the Seekers, gave away possessions and quit jobs, and on the night of the 20th pulled every scrap of metal off their clothes and sat down to wait. Three social psychologists led by Leon Festinger were sitting in the room under false names. Their 1956 book about that night, When Prophecy Fails, gave the world the phrase cognitive dissonance and is still assigned in classrooms. In this episode of Conspiracy Theories, Cults, & Crimes, Vanessa Richardson examines the prophecy Dorothy Martin took down from the Guardians, the researchers who joined under false names, and the private archive that undid a study taught in classrooms for 70 years.

In 2021, an anonymous forum post floated a theory that sounded absurd: the internet effectively died around 2016, and most of what we now see online, the posts, comments, arguments, and trends, is generated by bots and AI designed to manipulate what we think, buy, and believe. People laughed, until the evidence started piling up. Bots surpassed human traffic online for the first time in 2024, more than a third of new websites are now AI-generated, and state actors run thousands of fake accounts to shape public opinion. With every passing month, the idea that the internet is fake looks less like a conspiracy theory and more like a description of reality. In this episode of Conspiracy Theories, Cults, & Crimes, Vanessa examines the Dead Internet Theory, the mounting signs that much of the online world is no longer human, and the unsettling question of what happens to a society that can no longer tell the difference.
