Daniel Peterson wrote:The fundamental value of a scholarly work is intrinsic to it, and does not depend even slightly on the size of its audience or its degree of acceptance. Gregor Mendel's pioneer article on genetics was no more sound when it was noticed by other scientists than it had been during its decades of obscurity. Alfred Wegener's theory of continental drift was just as true when he first began to advocate it publicly in 1912 as it was in the 1950s when it finally began to gain general acceptance. (Unfortunately, Wegener died in 1930 during an expedition to Antarctica, when his theory was still generally rejected.)
The "just because no one else believes it, does't mean it's not true" argument always gets a lot of play by those endorsing fringe science. As the argument itself presents no reason to actually put any stock in it other than new ideas warrant investigation, a useful ratio to look at in these cases is the amount of energy expended in that argument relative to the energy spent on expounding on the evidence for the alternative view. Not a terribly good one so far.
The two examples above (Mendel and Wegener) are also quite poor in justifying the "just because no one believes it, doesn't it's not true" argument. Mendel was not discounted - his obscurity came from publishing in obscure places that people that would have been in a position to recognize its worth were unlikely to see (and didn't for quite some time). His work was readily acknowledged when it surfaced in scientific circles. Diffusional models of Maya-Near East communication definitely does not suffer from Medellian like obscurity in that no one has encountered it.
In contrast, Wegener's Continental Drift was discounted on very strong grounds - the mechanism of continents plowing through oceanic crust like icebergs through the sea is entirely unfeasible. But given the evidence he marshaled for the continents once being together, it was not long after plate tectonics was proposed that plate tectonic theory (not Continental Drift) became widely accepted. In the diffusional model case, Sorenson is ultimately hoping to provide an implicit mechanism (Book of Mormon voyages) to explain a model with a continually shrinking number of adherents as more evidence for the workings of Mayan culture amassed - not a promising situation for his "results of research that, because of its unconventional or controversial nature, might otherwise go unpublished."
ETA: Wegener died in Greenland, not Antarctica. And it is unfortunate that he did not live long enough to see the advent of plate tectonics. I suspect he would have been quite thrilled with it, even if it wasn't exactly what he was proposing.
