Rationalist Community
The rationalist community is a 21st century movement that formed around a group of internet blogs, primarily LessWrong and Astral Codex Ten (formerly known as Slate Star Codex). The movement initially gained prominence in the San Francisco Bay Area. Its members seek to use rationality to avoid cognitive biases. Common interests include transhumanism, statistics, effective altruism, and mitigating existential risk from artificial general intelligence. Beliefs The community began with a simple idea: "Each day, we aim to be less wrong about the world than the day before." They refer to rationality as the art of thinking in ways that result in accurate beliefs and good decisions. Public perception and media coverage focus on the group's use of Bayesian inference, which some adherents claim is the "least imperfect" way to think. Tara Burton wrote in ''The New Atlantis (journal), The New Atlantis'': "Central to the rationalist worldview was the idea that nothing — not social niceti ...

Scientific Racism
Scientific racism, sometimes termed biological racism, is the pseudoscience, pseudoscientific belief that the Human, human species is divided into biologically distinct taxa called "race (human categorization), races", and that empirical evidence exists to support or justify racial discrimination, racial inferiority, or racial superiority.. "Few tragedies can be more extensive than the stunting of life, few injustices deeper than the denial of an opportunity to strive or even to hope, by a limit imposed from without, but falsely identified as lying within". Before the mid-20th century, scientific racism was accepted throughout the scientific community, but it is no longer considered scientific. The division of humankind into biologically separate groups, along with the assignment of particular physical and mental characteristics to these groups through constructing and applying corresponding Scientific modelling, explanatory models, is referred to as racialism, racial realism ...

Ziz LaSota
The Zizians are an informal group of rationalists with anarchist and vegan beliefs who also believe the hemispheres of the brain can have conflicting interests and identities. They are allegedly involved in six violent deaths in the United States, three in 2022 and three in 2025. Federal prosecutors say the Zizians are associated with persons of interest in the murders of four people: David Maland in Vermont (a U.S. Border Patrol agent), Curtis Lind in California (a landlord), and Richard and Rita Zajko in Pennsylvania (the parents of one of the group members). In addition, Ophelia Bauckholt (a German citizen) and Emma Borhanian, both associates of the Zizians, were killed during altercations with Maland and Lind. The term ''Zizians'' is derived from the name of Ziz LaSota, who is sometimes characterized as their leader. They themselves do not use this name or consider themselves to have a clearly identified leader, or even to be members of a group. Beliefs The Zizians, a sma ...
