This unfortunately refers to Ziz as 'her' throughout - Ziz is male - but it is still an interesting article about the Zizians and what the cult believes.

The thread about the Zizians on the Farms (thanks to Coo Coo Bird for the quote below) has this explanation of terms which might also be helpful. There is a lot of information on there which I cannot post here, but I do recommend reading the first post on the Farms thread (easy to find by searching for 'Zizians' on that website).
"Rationalism - In theory, rationalism is the view that reason is the most important source of knowledge, as opposed to faith or experience. In practice, this means self important nerds acting like they know everything already because they got high SAT scores. The Bay Area and Silicon Valley is full of rationalist cults, especially concerning AI, which they believe will bring about the Singularity.
Effective Altruism (EA) - A belief that it's mathematically more beneficial to amass large sums of money to donate to ending poverty than to volunteer to help people in person. In other words, it's an excuse to pursue money and power "for the good of mankind". See: Sam Bankman-Fried.
Harry Potter and the Methods of Rationality (HPMOR) - The Bible for rationalists is Eliezer Yudkowsky's fanfiction retelling Harry Potter using rationalism. Other "essential rationalist literature" includes Luminosity, a Twilight fanfic, and Friendship is Optimal, a My Little Pony fanfic. The only 'original' work of rationalist literature seems to be Worm, which is an edgy capeshit webnovel.
Infohazard - Sometimes called "cognitohazard". As rationalists define it, information that is considered dangerous enough to drive someone insane. This is used as a cope for how many rationalists commit suicide: "We're not mentally ill, we just deal with knowledge too dangerous for ordinary mortals!" and an excuse to censor/obscure information.
Roko's Basilisk - The concept that a superintelligence will punish people who did not contribute to its existence by making a hyperrealistic simulation of them and torturing them. Just a lamer Pascal's Wager.
Singleton - The concept of a single intelligence ruling the world, usually an AI. Rationalists believe their research will determine if the Singleton will make the world Computer Heaven or Computer Hell.
The Singularity - The technological singularity is a hypothetical future where computer intelligence grows uncontrollable and changes humanity forever, possibly even destroying it. The Rapture for nerds."
