This summer I've been doing research in the field of holographic optical traps. As part of my preparation I did some literature review on the published papers in this area. It was interesting to find that there was a core group of people, about ten or twenty strong, whose names always came up. You couldn't find a good paper on optical traps that didn't have them as a co-author.
Sociologically, that's an interesting phenomenon. Are there only twenty people in the world who work on optical traps? (How on Earth did I get one of them for my supervisor? XD) Surely there are more. Is it that the others don't publish papers? That their work is not good enough to be published in a journal? Maybe journals take a look at the author list, think to themselves "If this article was really any good it would have David Grier or Jennifer Curtis on it" and throw it out?
The question seems academic. ("Academic"! Heh heh.) What matters is that the papers I
do see report phenomena that I can directly duplicate right here in my own lab with my own dinky little holographic optical trap setup. Journal papers may
communicate science but they
aren't science.
The fact that there aren't any YEC papers (not papers authored by YECs, but papers which specifically show evidence for YEC theories) in respectable journals shows that YECs aren't able to communicate their theories to mainstream science effectively through journals. Does this show that what they're doing isn't science? Or just that journals don't accept what they're doing as science (even if it is)? Of course I happen to believe the former, but I don't think that journals can settle it one way or the other. When laptoppop says:
I would of course postulate a third option: that YEC really
is junk.

But I don't see how you can distinguish between those options just from the fact that YEC papers don't get published.
Personally, of course, I think the whole "establishment control" argument is quite silly. Why should a peer reviewer be offended if an article attempts to state that the Earth is six thousand years old? I can believe that the earth is young and still be an atheist, or a Muslim, or a Christian, or whatever. I can believe that the earth was once covered by a global flood that nearly wiped out all life and not give a whit about the Bible. The same people who think a global flood unlikely believe that 650 million years ago an asteroid hit the Earth and nearly wiped out all terrestrial life. It's silly to say creationists are silly simply because they believe in a global flood (in much the same way that it is silly for creationists to call conventional geology "uniformitarian" - how uniformitarian is a meteor strike?).
But I don't actually know any peer reviewers. And as much as there are closed-minded creationists who simply don't consider alternative viewpoints, there are also closed-minded evolutionists who certainly would dismiss any YEC paper offhand without even giving it a read. Who knows, maybe they're the real reason that YEC papers don't get published?
As for me personally, YECism just doesn't explain anything well. The fact that it doesn't have journal publishings to its name is really just coincidental.
