I recently found out about Marilyn vos Savant, the smartest person in the world, who became quite a big deal back in the 1980s (I didn't watch much T.V. in the 1980s, so I can see how I could have missed this). Maybe the Bonnie situation is inspired by her.
Yes, we were backward back in the 1960s--but think of who all the smartest people in the world have been in very recent comics--it's a sausage party! So maybe not everyone has come such a long way baby.
