Scientific racism. it has to be the out of if not the most influential form of pseudoscience. Pseudoscience consists of statements, beliefs, or practices that are claimed to be both scientific and factual but are incompatible with the scientific method. Theses can range from a silly internet "joke" said a thousand times. Such as flat earth, or something life threatening to young children. Anti-vaccination, or something as negatively impactful throughout civilization across cultures and centuries, and is the very foundations of racism. Scientific Racism. During the Age of Enlightenment (an era from the 1650s to the 1780s), concepts of monogenism and polygenism became popular, though they would only be systematized epistemologically during the 19th century. Monogenism contends that all races have a single origin, while polygenism is the idea that each race has a separate origin. Until the 18th century, the words "race" and "species" were interchangeable. These incredibly biased ideas ranged from stating that whites are the superior race, to comparing the skull structure of black people to monkeys. Which makes no sense what so ever since everyone has a different skull structure and labeling it to race is pretty ignorant.
