The 'study' you linked is a shitty article so this dude can sell his book. He doesn't even link the study in the article. Just some random fuck saying 'our study showed this'. 
  
 MIT is one of the top schools in the world.

The book is about the study, written by a dude with a Ph.D in business admin. 
  
 Regardless if it is MIT, simulation is a laughable excuse for real world data, especially something as np-hard as this question.
