There are far more crazy belief systems in existence than the “treasure” and “heresies” of Abbé Bérenger Saunière and Rennes-le-Château.

Take for example headlines such as “NYT conservative warns Trump put religious MAGA supporters in spiritual peril” and “Social Media Influencer Claims Space Aliens Helped Egyptians Colonize Kentucky” – the mad beliefs of the Human Race never cease to amuse serious-minded and level-headed people!

The idea that “mad” or irrational beliefs are not always increasing, and that they do not inherently define human history, can be supported by analyzing how beliefs function. While “mad” beliefs – defined as strongly held, inaccurate, or unsubstantiated thoughts – can appear widespread, they are often entrenched in the social identity and personal psychology of a group, rather than experiencing a linear increase in prevalence.

“Mad” or deeply irrational, bizarre, and non-normative beliefs have indeed existed throughout human history, taking various forms from supernatural explanations of health to widespread conspiracies. These beliefs are often rooted in a need to explain the unknown, manage fear, or conform to social conditioning.

In 1900 BC, Mesopotamian and Egyptian texts described the “wandering uterus” (hysteria) as the cause of mental illness, believing the uterus could move around the body. In the Middle Ages, mental illness was frequently attributed to demonic possession or divine punishment.

In 1795, astronomer William Herschel believed the sun was cool and inhabited by life.

Historically, it was widely believed by the upper classes that women were too delicate for work, despite evidence of working-class women working 16-hour days in coal mines.

Conspiracy theories, such as the 2020 election being stolen or that the moon landings were faked, are staples of modern culture. Other examples include the belief in witches/familiars, which currently exist into the modern era.

These beliefs often persist because they provide emotional security or are heavily influenced by peers, rather than being based on evidence. Research into conspiracy theories shows that such beliefs are not necessarily increasing over time but are consistent, enduring features of human psychology.

Never underestimate the sheer stupidity of Humanity!
