Expertise vs Scholarship

I came across this article on Ars Technica “First, Kill All The Experts” and I was reminded of the importance of language.

The gist of the article is that people distrust experts leaving us vulnerable to the dangers of global warming, privatized health care, etc.  The confusion is that of scholarship vs expertise.  Seemingly if you can’t run tests or repeat the same experiments over and over you’re just well versed in the theories and literature.  Seemingly one would give more credence the the predictions of a structural engineer about a structure than a climatologists about the climate (or a macro-economist about the economy) .
