Big public infrastructure projects used to be synonymous with corruption, including bid rigging. Super-smart professors Jim McClave and Tom Rothrock figured out a way to detect bidding irregularities and catch cheaters. As a kid, Jim loved solving puzzles and did well at school, but suffered from bad “comportment” according to his teachers.  Tom, a farm boy from Missouri, went to a one-room schoolhouse in a town of 100. “Not a lot of education took place” so he struggled in school, but “math came easy” to him.  In 1977, Jim and Tom formed a business called InfoTech and have been collaborating ever since. *This episode was originally released on February 13, 2019.*
