That what they then produce for publication is represented as science is laughable in the extreme. It is anything but science. It is a parody or mockery of actual science. In legitimate science you don't get to cherry pick only the data that you think might support your presumptions must must also examine the stuff that appears to contradict them.
And that is exactly what does happen. I already mentioned the example of the noted paleontologist and entomologist Michael Engel and how he reacted when shown that he had been wrong about honey bees weren't in North America millions of years ago but had (relatively) recently migrated here from Europe or Asia. He didn't throw a fit. He didn't ignore the evidence that refuted what he was sure was the correct view. Instead he was thrilled that he "got to overturn some of my own stuff."
And this is far from some isolated instance. Scientists reject cherished beliefs if and when enough evidence can be amassed against it.
As Carl Sagan noted back in 1987 in a speech:
In science it often happens that scientists say, "You know that's a really good argument; my position is mistaken," and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day.[1]
Donald Prothero in his book "Evolution: What the Fossils Say and Why It Matters" cites a couple examples of just such occurrences taking place, such as with the issue of continental drift and plate tectonics. He notes that
"The Old Guard" who had a lot of time and research invested in fixed continents tended to be skeptical the longest, and many held out until the evidence became overwhelming. Eventually, they all had to concede their cherished beliefs were wrong.
Prothero revealed how the famous geologist Marshall Kay, who had spent his entire life explaining the complexities of geology based on the assumption that continents did not move (even publishing a major book on the topic), ended up embracing plate tectonics when the evidence for it started to amass. Even though he was near retirement age Kay began redoing his life's work using the new concepts and his work ended up providing a good deal of the geological evidence used in support of the theory.
Everybody's favorite Richard Dawkins has repeatedly recounted one instance that he has witnessed:
I have previously told the story of a respected elder statesman of the Zoology Department at Oxford when I was an undergraduate. For years he had passionately believed, and taught, that the Golgi Apparatus (a microscopic feature of the interior of cells) was not real: an artifact, an illusion. Every Monday afternoon it was the custom for the whole department to listen to a research talk by a visiting lecturer. One Monday, the visitor was an American cell biologist who presented completely convincing evidence that the Golgi Apparatus was real. At the end of the lecture, the old man strode to the front of the hall, shook the American by the hand and said--with passion--"My dear fellow, I wish to thank you. I have been wrong these fifteen years." We clapped our hands red.
I can continue giving example after example of this including debates over whether humans were in the Americas prior to the Clovis culture; the megaflood in eastern Washington that resulted in the formation of the Scablands; how a champion of the idea that whales arose from mesonychids abruptly changed his mind and agreed they actually arose from artiodactyls (an idea he had adamantly opposed) when he discovered a bone that contradicted his presumptions.
And yes I can include examples specifically relating to evolution.
There have been numerous examples of what were initially considered to be controversial theories (as they accounted for observed biological changes that did not correspond to the expectations of the neo-Darwinian models derived from the New Synthesis -- which itself over-turned pure Darwinian thought and theory -- that was developed in the mid 1930s through the mid 40s) that have been accepted.
- Like when Conrad Waddington proposed developmental evolution (evo-devo) in 1942
- Like when Willi Hennig proposed phylogenetic systematics (cladistics) in 1950
- Like when Motoo Kimura proposed the neutral theory of molecular evolution (genetic drift) in 1968
- Like when Lynn Margulis proposed Endosymbiotic theory in 1970
- Like when Niles Eldredge and Stephen Jay Gould proposed punctuated equilibrium in 1973
- Like when Carl Woese proposed horizontal gene transfer in 1977
What none of the scientists who initially opposed any of the above mentioned items ever did was automatically reject the evidence that showed that their cherished ideas had been mistaken. They didn't dismiss it because they had signed an oath demanding that they unconditionally dismiss any and everything that didn't support what they had already concluded. And they certainly didn't throw a hissy fit and threaten those who questioned them with going to hell for daring to disagree as YEC John Baumgardner did as he ran off during a discussion about the RATE (Radioisotopes and the Age of The Earth) project with Kirk Bertsche and several others after just a few exchanges here at Tweb a few years back.
ETA: Another example of what I'm talking about can be seen in the different replies that Bill Nye and YEC leader Ken Ham provided during their debate last year when asked if there is anything that could get them to change their mind. Nye responded that evidence could whereas Ham intoned that nothing could.
1. As Sagan notes it doesn't happen enough and I'll add that there will always be holdouts but in general science advances when new information demonstrates an old view does not reflect reality. If it didn't we would still think that the earth was immobile and the sun revolved around it or the elements consist of air, earth, fire and water.
