In traditional Jewish culture there is a large emphasis on education. In the most traditional sense, Rabbis are essentially scholars. They study the Torah. In ancient times they would sit around and do nothing but study the Torah and discuss its various interpretations--this was their primary purpose. You might consider them among the world's first pedants :) In traditional communities Rabbis are among the most respected members. Consequently, there is tremendous value placed on qualities of intelligence and conscientious study. Fast forward to current times and that still exists to a great degree in modern Jewish culture (in my experience).
