Consider the alien source of life hypothesis or ASL:
Life evolved on another planet and developed an intelligent space-faring race. This race travelled around the galaxy seeding life on various planets, including Earth. Suppose that the aliens have visited Earth every few million years and added new organisms, and that all diversity above the level of genera was created by this alien species. That is, evolution has led to the diversity of genera and species, but that all levels above that were created by the alien race.
Suppose that the ASL were true. Suppose further that strong evidence of the ASL were available to modern science in the form of
Evidence based on genetics and chemistry that diversification above the level of genus requires so many simultaneous mutations that it is astronomically unlikely to have occurred even once in the history of life.
Evidence in the fossil record that many higher level categories seem to arise spontaneously, without precursors, and that it is common for many of these new categories to arise at about the same time.
Engineering analysis that suggests life was assembled from a toolkit with certain standard tools, materials, and techniques.
Would today's atmosphere of hostility towards any suggestion of design make it impossible for science to ever acknowledge and seriously consider the evidence 1, 2, and 3, and therefore make it impossible for science to ever discover the truth of ASL?
Note that there have already been arguments made for 1 and 2 by the ID community, but any scientist who takes this evidence seriously or any editor of a scientific journal who publishes an article that takes this evidence seriously can expect to have his career destroyed. Under such conditions, how can the evidence ever be seriously evaluated? And does the impossibility of having a serious discussion about these issues represent a failure of science?
Related considerations: teleological framing reportedly seems ineliminable from biology in general. As Kant argues:
The highest formal unity, which is based upon ideas alone, is the unity of all things—a unity in accordance with an aim or purpose; and the speculative interest of reason renders it necessary to regard all order in the world as if it originated from the intention and design of a supreme reason. This principle unfolds to the view of reason in the sphere of experience new and enlarged prospects, and invites it to connect the phenomena of the world according to teleological laws, and in this way to attain to the highest possible degree of systematic unity. The hypothesis of a supreme intelligence, as the sole cause of the universe—an intelligence which has for us no more than an ideal existence—is accordingly always of the greatest service to reason. Thus, if we presuppose, in relation to the figure of the earth (which is round, but somewhat flattened at the poles),[30] or that of mountains or seas, wise designs on the part of an author of the universe, we cannot fail to make, by the light of this supposition, a great number of interesting discoveries [emphasis added]. If we keep to this hypothesis, as a principle which is purely regulative, even error cannot be very detrimental. For, in this case, error can have no more serious consequences than that, where we expected to discover a teleological connection (nexus finalis), only a mechanical or physical connection appears. In such a case, we merely fail to find the additional form of unity we expected, but we do not lose the rational unity which the mind requires in its procedure in experience. But even a miscarriage of this sort cannot affect the law in its general and teleological relations. For although we may convict an anatomist of an error, when he connects the limb of some animal with a certain purpose, it is quite impossible to prove in a single case that any arrangement of nature, be it what it may, is entirely without aim or design.
With respect to the issue of anti-creationist bias: although the SEP article on creationism itself is openly hostile to intelligent-design theory (calling it scientifically worthless, philosophically confused, and theologically "blinkered beyond repair"), a generally related SEP article on fine-tuning questions in cosmology is more sympathetic (or at least nonconfrontational). Moreover, the article on teleological arguments for the existence of God says:
We will not pursue that dispute here except to note that even if the case is made that ID could not count as proper science, which is controversial,[12] that would not in itself demonstrate a defect in design arguments as such. Science need not be seen as exhausting the space of legitimate conclusions from empirical data. In any case, the floods of vitriol flowing from both sides in the current ID discussion suggest that much more than the propriety of selected inferences from particular empirical evidences is at issue.
ADDENDUM
I'll point to the three downvotes on this question in about an hour as evidence of the extraordinary hostility expressed towards anything that might in any way lend any oblique support for creationism. Even a discussion about whether this reflexive anti-creationism might have harmful side effects on science is met with hostility.
