Aggressively-Ignorant 

(Adjective) - A category of person or organization that goes out of their way to avoid knowing or learning about something so as to avoid responsibility or duty to act.

Usually associated with someone who exhibits either a general lack of intellectural curiosity or just plain burned out in their careers so they don't even try to improve themselves. These individuals are motivated by a strong desire to be the opposite of the "go-to-guy" so as to discourage requests for help or challenging assignments.
