Eugenics: positive vs negative

The distinction between positive and negative eugenics is perhaps the best-known distinction that has been made between forms that eugenics takes. Roughly, positive eugenics refers to efforts aimed at increasing desirable traits, while negative eugenics refers to efforts aimed at decreasing undesirable traits. Still, it is easy to fall into confusion in drawing and deploying the distinction in particular contexts. Clarity here is important not only historically, but also for appeals to the distinction in contemporary discussions of “new eugenics” or “newgenics”.
