Specifically, those who have an IQ between 0 and 25 are idiots; IQs between 26 and 50 are considered imbeciles; and those who have an IQ between 51 and 70 are considered morons.

These terms were popular in psychology as associated with intelligence on an IQ test until around the 1960s.

In my opinion all the aforementioned IQ ranges are still far above what is, at times, displayed in the US.

There’s no advice that’s going to be effective in stopping poop in those circumstances…
