Case in point: her claim that Brent Metcalfe, one of the most important Book of Abraham scholars in the world, isn't a credentialed handwriting analyst (or whatever her term was), so therefore his arguments don't matter, aren't valid, etc. For juliann (and many other Mopologists), credentials are critical, and can, in effect, be said to function as an emblem of a person's intelligence. (At least according to them.)
What do people think about this? How important are credentials for
1) Historians
2) Scientists
3) Inventors
This seems to be an easy question. Credentials are essential for any area where you expect me to trust that what you say is correct. If you expect me to take what you say when I don't have the required expertise, then you should convince me by the weight of your credentials that you know what you are saying.
Historians should therefore be able to present their credentials to establish that basis of trust.
What about their arguments? I constantly read books by credentialed historians which are full of mistakes. Let's take the case of a statement by a notable non-historian. Brad Parkinson is credited by many with being a co-inventor of GPS. Yet he has made important mistakes. He asserted that
Unlike the various Navy systems, 621B provided altitude, as well as latitude and longitude. "To the Navy, navigation is essentially a two- dimensional problem, but the Air Force was definitely interested in the third dimension," Parkinson said.

I proved this to be wrong in an article I had published last August.
1) In his Electronic and Aerospace Convention (EASCON) address about
Timation on October 29, 1969, Roger Easton said, This paper discusses the
genesis of a mid-altitude system for continuous 3 dimension navigation.‰
2) Buisson and McCaskill discuss in detail the 3D results for 105 different
constellations in this study
J. A. Buisson and T. B. McCaskill, TIMATION Navigation Satellite System
Constellation Study, NRL Report 7389, Naval Research Laboratory, Washington,
D.C., 27 June 1972.
3) Phil Klass wrote the following in "Plans for Defense Navsat Reached",
Aviation Week and Space Technology, August 20, 1973, 65-66
"As additional TIMATION satellites are deployed, it becomes possible to make
position determination on a three-dimensional basis (including altitude) on
a more frequent basis.
Finally, with a total of 27 spacecraft deployed, a full 3-D continuously
available position-fixing capability is provided."
4) Simple logic leads to the conclusion that Timation was 3D. The GPS
clocks on the satellites are from TIMATION. The basic orbital
configurations are from TIMATION. GPS's 12 hour orbits have slightly better
coverage than the optimal TIMATION proposal of 8 hour orbits. The only
major difference between TIMATION and GPS is the signal, which has no effect
on the dimensionality. Consequently, one can validly assert GPS is 3D,
therefore TIMATION was 3D.
Credentials are not the key element since frequently folks with strong credentials take opposing positions; good arguments are.
