Urban Legend
There are different types of Nobel Prize. The Peace Prize goes to the flavor of the month personality, usually a politician of some sort, and politicians even lie on their IQ tests lol! The Literature Prize is also different because a fiction writer needs to be able to empathize with readers, and very-high-IQ people have problems understanding the way that ordinary people think.
For Physics and Medicine, try winning a Nobel with an IQ under 150.
The range 125 to 130 IQ must be a good "money-making" level as you are smart enough to solve difficult puzzles yet still able to communicate with the average person. Most CEO's and political presidents fall into this bracket.
