When first looking at the title I was thinking some flat earthers or other pseudoscience group, but they were talking about individuals that were literally labelled under the category "MORONS". Really got me there.Not really sure whether to say that this was a product of that time as they inspired the eugenics movement and the Nazi massacres. Although I would argue that those movement would have happened with or without this so called "research". I totally agree with the ending statement where we might see the topic with disgust but back in the day it was groundbreaking science. Hopefully the advancement we have made thus far would not be viewed by our future generations as how we view the 'intellectually crippled' or 'eugenics' research.
