Normalcy is a relatively new concept, which arose in 1800-1850 in western Europe and its North American colonized spaces. The word “normal” did not enter the English language until around 1840. Prior to the conept of normalcy there was the concept of the ieal, perceived as inachievable and everyone was on a continuum of imperfection. [..] Normalcy began with the creation of measurements and statistics. […] Almost all the early statisticians were also known eugenicists. It is not surprising perhaps since the notion of the norm and the average divided the populace into standard and substandard populations. Difference is thus projected onto stigmatized populations so all others can strive for the illusive normalcy.
