Do you believe non “academic” people are dumb?

In a recent Jamaicans.com forum discussion the memory of a classmate I had in Jamaica.  One person accused a group of people  of not  being smart mainly bases on academics . I realized why I don’t like the term “mediocre” or “dumb” because it tends to label people based on our expectations. This classmate was called dunce. His nickname was “Duncebat” and because he did not excel in the “traditional academic school work”. Today he is an acclaimed artist with many accolades.
