On page 10 of his book "
Voodoo Science", Robert Park writes:
What may begin as honest error, however, has a way of evolving through almost imperceptible steps from self-delusion to fraud. The line between foolishness and fraud is thin.
And on page 211:
...But most of the scientists and inventors we met started out like Joe Newman, believing that they had made a great discovery overlooked by everyone else. While it never pays to underestimate the human capacity for self-deception, they must at some point begin to realize that things are not behaving as they had supposed.
Like all those who have gone down this road before them, they will have reached a fork. In one direction lies the admission that they may have been mistaken. The more publicly and forcefully they have pressed their claim, the more difficult it will be to take that road. In the other direction is denial. Experiments may be repeated over and over in an attempt to make it come out "right," or elaborate explanations will be concocted as to why contrary evidence cannot be trusted. Endless reasons may be found to postpone critical experiments that might settle the issue. The further scientists travel down that road, the less likely it becomes that they will ever turn back. Every appearance on national television, every new investor, every bit of celebrity and wealth that comes their way makes turning back less likely. This is the road to fraud.
Unfortunately, I think Cornell is now headed directly down the road to fraud.
Why do I say that? For now, here are just a few specific reasons:
1. Cornell's
rejection of Sibley's so-called "wing-twisting hypothesis" is nothing short of astonishing.
A Pileated's wing-twisting is not a "hypothesis"; it is an indisputable
fact. This fact is borne out by clear photographic proof right in Sibley's paper (see the
manybirds.com Pileated); yet another good example is on the Stokes Birding Blog
here.
In the face of the clear photographic proof of Pileated wing-twisting, Cornell's continued defense of their stiff-winged "model" birds is preposterous.
2. As I mentioned here recently, Cornell is currently using a
bogus "wingbeat frequency" argument; what's more, they must
know that their claim is bogus. I don't see how anyone can actually see anywhere near 38 wingbeats in the Luneau video, regardless of the amount of "Ivory-bill Kool-Aid" consumed.
3. Cornell's illustration of the Luneau bird's position (see below) is completely and utterly absurd. Cornell's illustration is in the middle (from Figure 2 of Sibley's rebuttal paper).

I fail to see how any knowledgeable person could still defend that drawing, given the clear portrayal in Sibley's paper of the bird's actual position and movements.
4. Cornell's proposal and defense of the "
six-pixel bird" is ludicrous. In their response to Sibley's paper, they now actually claim that this "bird" is "leaning away" from the trunk!! (the bold font is mine):
Contrary to the interpretation of Sibley et al.(2), the black and white object apparent in the Luneau video 26 s before the bird flies is consistent in size (35 to 45 cm), shape (vertically elongate, leaning away from the trunk), and pattern (black with white central patch) with a perched ivory-billed woodpecker...
