Overview
Intelligent design (or "ID") is a direct creation theory which is often proposed as a valid alternative to the scientific theory of evolution, a.k.a. Darwinism. It is essentially creationism, but with any falsifiable claims (e.g. the creation of the earth being specifically pegged at approximately 4000 BC) removed, and only the claim of an "intelligent designer" – who might be God, but whose nature is left carefully unspecified and could just as easily be some form of extraterrestrial intelligence – remains.
ID is, then, basically a redress of the classical "argument by design" which has been debated for at least 2000 years (see Wikipedia), but stops before the assertion that God must be the intelligent being involved.
Intelligent Design treatises often spend considerable energy on criticizing Darwinism and debating the merits of ID over those of Evolution, rather than refining ID as a theory (e.g. attempting to determine the exact nature of the hypothesized interventions, at what points they happened, etc.). These criticisms and debates often raise valid (although not unanswerable) objections to Darwinism, but do not (despite the ID adherents' apparent belief to the contrary) present evidence actually in support of ID.
Scientific Claims
ID does make the following falsifiable claims:
- Certain organisms display what ID proponents call "irreducible complexity", i.e. organs which they claim would not function properly if even a small percentage of their components were absent or not functioning properly, and therefore these organs could not have evolved.
- The flagellum, which is actually a motor with "about 50 parts"
- Prediction: If ID is correct, the individual parts of the flagellum should be useless on their own.
- Dr. Kenneth Miller answers this by showing a sample organism which is missing 40 of the 50 parts and yet still functions "perfectly".
- Life could not have evolved by chance, according to mathematician Dr. William Dembski of Southern Baptist Theological Seminary, due to the vast improbability of functioning sequences of DNA happening to occur out of all the vastness (philosophy) number of possible alternatives
- This is based on two mistaken understandings:
- Error: The probability of any given genome (DNA sequence for an organism) happening to occur is the same as that of any other genome, i.e. they happen at random.
- Correction: This would only be true if organisms had been created as they are now in a single act. The theory of evolution posits that the genomes for each species evolved gradually over millions of years, starting from the shortest possible strands which could reproduce and gradually being edited over the eons by natural selection – adding on a bit here, trimming a bit there – until we arrive at all the different organisms there are today. Hence DNA sequences (like any engineering project, or like writing) tend to follow certain patterns which are a vanishingly small subset of all the possible patterns. Genomes which actually work as organisms are an even smaller subset of genomes which are constructed mainly of patterns in common use.
- Error: The DNA sequences found in organisms today were each created in their entirety, like a hand of cards being dealt, for the first organism to use them. There are only a vanishingly small number of "hands" (out of all the Vast number of possible hands) which might work as organisms, and the misunderstanding seems to be that we have from the beginning of life until now to "deal out" functioning organisms from a well-shuffled deck.
- Correction: Again, the patterns started out being relatively simple, and gradually evolved into the complex forms we see today.
- A legitimate question to ask is how that first pattern could have been created, since the "simplest pattern capable of copying itself" would seem to be quite complicated, but that discussion is outside the realm of evolution by natural selection (though not at all outside the realm of science).

- This is based on two mistaken understandings:
Behe and Dembski argued that there had to be an intelligent, deliberate influence in order to overcome these obstacles they thought they saw, but they would seem to have been clearly in error; one can only think that it is intellectual dishonesty which compels them (and other ID supporters) to continue making the case for ID without answering these points.
Origin: The Wedge Document
As a coherent theory, ID seems to have been created solely for the purpose of finding an argument which would be acceptable to Christians and yet would succeed where creationism, due to the illegality of teaching religion-based ideas as fact in US schools, had failed.
An apparently damning strategy paper generally referred to as The Wedge Document was written in 1998 by the Discovery Institute's Center for Science and Culture. The paper does not appear to be anywhere on DI's web site (currently only available on the AntiEvolution web site - "concise and accurate information for those who wish to critically examine the antievolution movement"), although there is one reply (available only in PDF at present) dated 2005-12-19 on DI's site. (This PDF should probably be transcribed at some point for easier access.)
The Wedge paper makes it clear that ID was created – at least, from the point of view of the DI/CSC – solely for the purpose of "[seeing] intelligent design theory as the dominant perspective in science", regardless of its veracity.

Comments
- If it is necessary to invoke a deity in order to explain gaps in the theory of evolution, why does ID stop there? For example, scientists are still trying to explain how galaxies are held together when the force of gravity seems to be insufficient; the current theory is that dark matter is responsible, but most scientists will admit that this theory is a bit lame. Why aren't the ID people arguing that God must be holding the galaxies together? And then there's the whole area of quantum physics... --Woozle, 17:20, 23 January 2006
- David Brin said (in Contrary Brin 2005-12-08), arguing that the repurposing of Creationism's arguments in the more scientific-sounding "Intelligent Design" guise, as cynical as it may seem, is actually a score for science:
Take a gander at so-called "Intelligent Design." Would they have retreated so far from older "Creationism"... using every trick to dress it up in scientific-sounding and rationalist language, eschewing every reference to religion and even dropping all mention of the age of the Earth/universe (!)... if they did not realize how deeply and strongly science and enlightenment still hold attraction to the American majority? |
