@Smilex Ejs and Ips are closed-loop thinkers; their filters narrow down data input (focus) so that rationalization processes can widen - hence, your first sentence is somewhat correct. One process has to be limited in order to allow another to run concurrently. Focus, which is essentially selective filtering, is important because the brain has limited processing capacity. However, I would propose that Ips are better at focus though they may often be less productive.....
