There are similarly competitive people in engineering disciplines, even. I think many of us know that person that when trying to argue why their problem solution is the best problem solution tend to try to be the loudest person in the room. (Some of us work to reform in college; others might be that way their entire lives.)

Back at university I went to dinner with one of those people who liked to talk loudly over other people, and another person who was normally soft-spoken but had been an officer in the Navy and therefore professionally trained in loudness.

The ensuing loudness war almost got us thrown out of the restaurant.
