No. The way I perceive it is not that 'people cling desperately to what they believe', rather it is 'people cling desperately to what they want to believe. Even when there is no genuine evidence to support what they want to believe. So they settle for unsupported evidence as being good enough so they can continue to believe what they want.
Believing in facts is only one form of belief.
I'm aware of the Coelacanth, awesome story. Got to see moving pics of one that was caught live and the folks tried to rescue, but being a deep water fish it eventually succumbed, but watching it use the limbed fins was such a unique experience, quite unlike any other fish I've seen.
I am essentially in agreement with you, but I'm going to go out on a limb and take Joe's side for a moment, in support of my statement.
I presume by "facts" you mean so-called "evidence," which implies science. At least that is pretty well how it typically breaks down. Included in that science is the belief in evolution. (I can already hear the cringing, so bear with and hear me out) I am going to presume a belief in evolution as it is commonly taught...and here I get all sorts of "excuse" answers as well, when I say "one species gradually becoming another," which draws fire as if I am saying a tabby cat becoming a wombat, which I am vociferously *NOT* saying. I am saying, for example, like an ape-ish animal to become human through transitional species.
Now...the trouble is that even among those who are *well* versed in the subject, there is no clear distinction on what *precisely* defines a species. First up I usually hear about the finches in Galapagos getting stronger beaks. So, does a bigger nose constitute a new species? Then I hear about the moths in Industrial England turning from grey to black. So, does skin color constitute a new species? And when I mention how different a Great Dane is from a Chihuahua...so are different breeds of dogs different species? I can go on, at length, and have on more than one occasion here, I'm welcome to point to them if you wish, gone toe to toe with very learned people...point is, grade school evolution as taught is chock full of holes. It is a belief, a functional belief that works *to a point,* after which various anomalies have to be accounted for (and are, in the field). And quite frankly most people never get beyond grade school evolution, even if they hold PhDs. For them, that is sufficient belief, and sufficient to scoff at any others who don't agree with their POV on the subject, behaving as if *all* "facts" and "evidence" were on their side...when in point of fact they are not.
So I feel justified in my statement as is, "people cling to what they believe," even when they are ultimately faced with challenges and contradictions. What do we hold as scientific truths today that will be scoffed at a hundred years from now?
Religion is another belief set (that works *to a point*), philosophy yet another (that works *to a point*)...and while there is nothing to stop a person from holding multiple belief sets, usually one dominates over the others in a person's mind. All belief sets have shortcomings...hence my comment.
