RationalWiki#Racialism (often "scientific racism" or "race realism" by its adherants) is the idea that humanity can be easily divided into well-defined biological categories ("races") that are both broad and clearly-defined. Racialism implies that these races are substantially physiologically different from each other and that these racial differences strongly determine the abilities and behavior of individuals and peoples.
This #pseudoscience is technically not the same as #racism, which is the belief that one or more of these various groups is "superior" or "inferior" to one or more others, usually in some vague, undefined way. But while racism and racialism are distinct concepts, their respective adherents do overlap a lot more than either would have you believe.
Racialism first developed in the 1700s. It remained virtually unchallenged until the 1930s-1960s, when genetics showed it to be erroneous.

Racialism
Racialism (also known as scientific racism) is a set of far-right pseudoscientific ideas which hold that humanity can at all be meaningfully divided into biological categories ("races") that are both broad (each category should include many humans, such as entire continents' populations) and clearly-defined (the categorization method should rarely misidentify someone's "race"). Racialism implies that these races are substantially physiologically different from each other to a degree which necessitates biological classification similar to or below the species level and that these racial differences strongly determine the abilities and behavior of individuals and peoples. In short, racialism holds that biology neatly divides humans.
