Our struggle against half-wits

If my email correspondence is any indication, this ACW field is rich in readers struggling against the negligence and ignorance of "experts." Today, John Robb offers a turn of phrase from his sphere that captures the problem in ours:
I agree with John Boyd in [that] the term "expert" is akin to "half-wit" since expertise in a rapidly evolving field of knowledge is only valid on the first day it is attained. After that, you become a dogmatist unless you are constantly engaged in the synthesis necessary for updating your ideas.
We look at the great names in Civil War publishing and we see no updating. Dogma galore, though.
