ID is a science as it predicts evidence that suggests we did not find ourselves in the universe by chance. It is testable from a couple avenues.

I'm also looking for a chapter from a guy's PhD dissertation in biology, I believe. I'll tack it on if I can find it later.
I'm afraid that I'm going to have to side with jfern on this one, at least from the angle of holding the opinion that intelligent design is not science due to my belief that it is not, in fact, testable. That article you posted is very long and impressive-sounding, but I did not detect a whole lot of real meat to it, and it seems to be attacking evolution a lot more than promoting intelligent design.
It doesn't do a very good job of presenting both sides of the argument, either, something I consider absolutely crucial for me to consider it an objective article. While this obviously does not immediately refute anything, it does put doubt in my mind initially regarding its credibility. It does make the admission that intelligent design predicts nothing, but really, you can't very well make any sort of argument whatsoever that it does. I will nonetheless give it credit for that, though. However, I still got the sense that that article displays the age old problem of having a conclusion in mind and then going to look for evidence - a very unscientific approach.
Taken section by section, here's my analysis of what it has to say in its attempt to show that intelligent design is testable:
FalsifiabilityEssentially, stripping away everything else, the article appears to be claiming that Occam's Razor can be used to falsify intelligent design. This is a completely false claim; Occam's Razor is not a scientific theory and is merely a statement about what Occam felt was common sense: that the simplest theory, or in his words, the theory that requires the least amount of assumptions, is most likely to be the correct one. One should note the presence of the qualifier "most likely" - Occam's Razor says nothing about what
is correct, only what is most likely to be correct. It offers no proof for this claim, which is, of course, perfectly allowable because, it's not supposed to be something scientists use to verify scientific theories.
Quite frankly, I can't see how intelligent design is falsifiable. Even if you can show that everything in the entire universe
can be produced through a series of mutations, that doesn't prove that it
was produced in that fashion. It may well have been created by some intelligent designer even so. We really can't know (at least at this point in time), and it's debatable if we can ever know for sure.
The rest of this section is committing one gigantic
burden of proof fallacy by making numerous attacks on evolution and those who believe in evolution, ignoring the fact that evolution's merits (or lack thereof) say nothing about intelligent design's merits.
ConfirmationHere's this section in a nutshell:
Blah, blah, blah,
Contact, SETI, blah, blah, complexity, intelligent-sounding names.
I'm being facetious, of course, but really, this section says both a ton and extremely little at the same time - somewhat of an
argumentum ad vis (argument by quantity), if you will. The only actual important bit that it offers is the idea that finding something irreducably complex would be confirmation of intelligent design. What it doesn't mention is whether it's possible to conclusively prove whether or not something is irreducably complex. In the section on falsifiability, he states that evolution is not falsifiable because it's impossible to prove beyond a shadow of a doubt that something is irreducably complex. Then, in this section, he merrily asserts that finding something irreducably complex will confirm intelligent design.
Unfortunately for the writer, this is a blatant contradiction, and, sadly, he can't have his cake and eat it too. Either evolution is unfalsifiable, or intelligent design is not confirmable. He has quite effectively shot himself in the foot without even batting an eyelash. Asserting these two mutually exclusive ideas to both be true seriously damages his ability to appear to have written a completely objective article.
Regarding which one of the two is true, I personally currently feel that intelligent design is not confirmable, barring the chance of actually finding the creator and having him give you a demonstration. I say this not simply because I want it to be true, but because I can't see how it's otherwise possible to prove a biological construct to be irreducably complex. It seems to me that it could very well be the case that we simply don't understand the evolutionary steps that led to the construct.
I will concede that this does imply that evolution is not falsifiable, which
is certainly an argument against evolution as a scientific theory, but I am not going to fall into the trap that the writer of this article fell into so many times of considering an argument against evolution to be an argument in favor of intelligent design. It's not. The truthfulness of the two theories are entirely detached and unrelated from one another, and his article would be a lot more effective if he purged it of all irrelevant material attempting to disprove evolution.
The rest of this section is essentially a lot of irrelevant mindless chatter that need not be discussed.
PredictabilityThe article displays multiple paragraphs to essentially just concede the point that intelligent design does not predict anything. There's no point in attempting to show what it already admits.
Explanatory PowerYeah, okay, I'll concede this point. Intelligent design does explain a lot of things if it's true. I can't really dispute this point.
What I
can note, however, is that this quality, while necessary for something to be a scientific theory, is not nearly sufficient for something to be a scientific theory. Intelligent design is not falsifiable, is not confirmable unless someone can show how you can prove absolutely conclusively that something is irreducably complex, and does not predict anything. The fact that it would explains things if it were true is, therefore, entirely irrelevant. All things considered, I maintain that intelligent design is not a scientific theory.
