I worked for over 40 years at a major corporation with engineers in every discipline; nuclear, mechanical, electrical, civil, computer, robotics -- you name it. At that same company I also worked with a fair number of corp lawyers over the years. They just had different jobs to do. I even knew one who had both an engineering and a law degree. He could do both very well.
I would never put one over the other in intelligence. I have know some of each who were brilliant, most competent, and a small number of others who I always wondered how they found their way to work in the morning.
