Kurt Vonnegut, “Breakfast of Champions; or, Goodbye Blue Monday”

Agreeing machines

Patty Keene was stupid on purpose, which was the case with most women in Midland City. The women all had big minds because they were big animals, but they did not use them much for this reason: unusual ideas could make enemies, and the women, if they were going to achieve any sort of comfort and safety, needed all the friends they could get.

So, in the interests of survival, they trained themselves to be agreeing machines instead of thinking machines. All their minds had to do was to discover what other people were thinking, and then they thought that, too.
