Definition: Pseudo-arch is a term used to describe the concept of a fabricated or constructed alternative to existing reality, often involving pseudoscience or conspiracy theories. It is often associated with an underlying psychological or philosophical underpinning that goes against established knowledge or societal norms. The term "pseudo-arch" was first coined by historian David Lloyd in his book "Psychological Theories," and it refers to a type of pseudoscience or alternative theory that seeks to falsify existing scientific theories. It is often used by conspiracy theorists, activists, and other groups who seek to undermine established institutions and systems. The term "pseudo-arch" has been criticized for being a misnomer because it does not accurately reflect the nature of its use or significance. However, some individuals may see it as a convenient way to justify their beliefs without taking into account the underlying psychological or philosophical underpinnings of their pseudoscience.
