“”Try this experiment if you ever find yourself talking to a proponent of ID. Say, "OK, for the sake of argument let's say evolution is wrong and let's forget about it. Now tell me how intelligent design works." Having tried this a few times myself, I am confident that you will be met with nothing but an awkward silence.
Intelligent design creationism (often referred to as intelligent design or "ID") is a pseudoscience that maintains that certain aspects of the physical world, and more specifically life, show signs of having been designed, and hence were designed, by an intelligent being (usually, but not always, the God of the Christian religion). The concept is older than science, but only since the 1980s has the term "intelligent design" been in circulation. Supporters of intelligent design (termed design proponents, or, once, cdesign proponentsists) usually claim that the theory is not based on Christian creationism, although the existence of the Wedge Document is a pretty big hint that there is some link. Attempts to have ID taught in public schools have been defeated in court, and science papers proposing a "designer" usually cannot get past peer review - although not for reasons of prejudice against the subject matter. Intelligent design has been widely criticised for its failure to state what mechanism drives it, its lack of falsifiability, and many other problems that leave it lacking as a scientific theory.

The concept of the world and its creatures and people having been intelligently designed is a very old one, central to creationism and common to many of the world's religions. It is one of the oldest themes of philosophy, having been explored by Plato and Aristotle. In Christianity, the concept of intelligent design by a creator is perpetuated by the Biblical account of the creation. That the world and its creatures aren't just the product of, but actually evidence of intelligent design is known as the teleological argument or argument from design. It has been used more frequently in modern times than previously, particularly after the complexity of the biological cell was realised. One famous example was William Paley's 1802 use of the "watchmaker analogy," which posits that the complexity of natural life must be the product of an intelligent creator in the same way that a watch must be the product of a watchmaker - and specifically that it is possible to tell the difference between designed and non-designed objects intuitively.
The term "intelligent design" emerged much more recently than the design argument itself. It had been used occasionally during the twentieth century, but was popularized after the 1987 legal case of Edwards v. Aguillard, in which "creation science" was ruled to be a religious concept, and therefore unfit to be taught in public schools under American law. Subsequently, many aspects of creation science were rebranded as "intelligent design," which is ostensibly a non-religious concept since its adherents claim that it leaves open the question of who the designer might be.
The Discovery Institute has taken the lead in promoting intelligent design, and urging for it to be incorporated into public education. The Discovery Institute's Wedge Document specifically states that the intelligent designer is the Christian God, thus undercutting the claims that the intelligent design movement is not strictly religious. In the Kitzmiller v. Dover Area School District case (2005), the Court found that intelligent design was primarily religious and fostered unnecessary entanglement of church and state. The Court further found that intelligent design is not science.
 Designed by whom?
“”Possible candidates for the role of designer include: the God of Christianity; an angel--fallen or not; Plato's demi-urge; some mystical new age force; space aliens from Alpha Centauri; time travelers; or some utterly unknown intelligent being.
Almost all proponents of intelligent design have been theists, arguing that the creator must be God. ID is advanced by many "Young Earth creationists," who use it to rebut the theory of evolution, and, by extension, the facts that support it. Their position is generally that evolution through natural selection and physical forces and principles alone is not solely responsible for the current diversity of life on earth. However, some believers in "Old Earth creationism" believe intelligent design to be the guiding mechanism behind theistic evolution.
The intelligent design argument is not incompatible with atheism, since, even if one accepts that the complexity of nature proves an intelligent designer, this does not logically prove that the "designer" has the characteristics of a god or is worthy of worship. Some (largely obscure) intelligent design theories conjecture that life on earth could have been cultivated by intelligent extraterrestrial beings. Francis Crick is sometimes cited as an example of an atheist ID proponent, since his concept of directed panspermia arguably shared some concepts with ID. Crick later partially retracted his claim based on an what he called an overly pessimistic model for abiogenesis.
Some ID proponents honestly acknowledge that their critique is informed by a rejection of the methodological naturalism, by which physical science examines the world, and consequently cannot be science. Others are a bit more evasive, but the overwhelming majority of scientists dismiss intelligent design as being pseudoscience.
Ironically, most intelligent design proponents appear to consider the idea that aliens designed everything on Earth as "silly," which is strange considering extraterrestrial design has the following advantages over god-based design:
- Not scientifically impossible. (Assuming that FTL technologies exist). No superstitious or supernatural elements that couldn't be duplicated by any "normal" being are assumed.
- Doesn't necessarily conflict with evolution. Even in a designed ecosystem evolution could still occur and nothing prevents the aliens from having evolved normally themselves.
- A plethora of reported sightings, carvings, photographs, radar signatures, all of which (regardless of their authenticity) are a lot more evidence than the number of sightings and photographs of God.
- Explanation for mistakes, illness, nature's cruelty etc. Since physical beings do not have any obligation to be "all perfect" or "all loving," aliens get a free pass on that.
 The wedge strategy and the "Trojan horse" of creationism
Intelligent design has been strongly pushed by the Discovery Institute as part of the wedge strategy as outlined in the Wedge Document in their attempt to create a sciency-sounding version of creationism. It has been roundly rejected by most scientists on the grounds that it has no peer-reviewed publications of any standards, and has produced no positive evidence for its claims. The wedge strategy itself is to create a public furor over the concept of "teaching the controversy." In the real scientific world, of course, there is no such controversy over the facts and theories underlying modern concepts of evolution.
To date, intelligent design has been officially introduced into exactly one school district - and there, it tore apart the community, cost the school board millions of dollars, and was eventually thrown out after the Kitzmiller trial. Although intelligent design is always a "Trojan horse" for creationism - that is to say, creationism with a new name and a few obfuscating principles - there is a sliding scale of how egregious and visible the disguise is. Some people actually believe it to be real science (albeit erroneously), while others use it as a clear pretext for preaching, er, teaching creationism.
In the Kitzmiller case, the disguise was patently obvious. "Intelligent design proponents" there sought to have the book Of Pandas and People, a creationist screed, taught as part of a new "intelligent design" curriculum at the local Dover public high school. ID supporters hoped to prove at trial that the book was legitimate science, and not creationism. However, there was one slight problem - the book was a book about creationism, with the words "creator," "creationism," etc., merely replaced with "designer," "intelligent design," etc. by a basic word-processor "find/replace" function. The ruse was made glaringly obvious by spelling errors like "cdesign proponentsists."
 Legal issues in education
- For the main article on this important issue, please see Kitzmiller v. Dover Area School District.
No appellate precedent exists by which to judge the legality of teaching intelligent design in public schools. However, in the landmark district federal court case, Kitzmiller v. Dover Area School District, Judge John E. Jones III ruled that given that the policy of teaching intelligent design was supported by religious rhetoric, it amounted to a teaching of religion by the state, in violation of the First Amendment of the United States Constitution.
Intelligent design was "religion" because, in the legal language applied, a reasonable person (based on the events surrounding the policy's adoption) could have concluded that it had the purpose or effect of establishing a particular religion. In short, when a school board tries to teach intelligent design, the level of religious rhetoric is directly related to the likelihood of its unconstitutionality under the Lemon v. Kurtzmann test.
This precedent, and the correlation it establishes between religious rhetoric and the likelihood of any intelligent design policy being found unconstitutional, will be vitally important in heading off future school boards which attempt to teach intelligent design as "science." Intelligent design's "wedge" appeal rests on its attempt to characterize itself as non-religious, after all. Fortunately, the idea that intelligent design is non-religious is being rebutted on a practically daily basis... by its own proponents.
Consider a Kentucky schoolteacher who sought to teach intelligent design to her seventh grade biology class. The teacher curiously taught the "scientific theory" as something practically indistinguishable from creationism, complete with flood geology and young earth chronology. The school board, after being made aware of the same by the ACLU, and the likely legal troubles it would face, terminated its tacit approval of intelligent design.
Additionally, the leading light of intelligent design, Michael Behe, is only able to publish his pro-intelligent design theories in one scientific journal - Philosophia Christi - the proceedings of the Evangelical Philosophy Society.
And finally, the "movie" Expelled: No Intelligence Allowed, which bills itself as describing how intelligent design is systematically excluded from academia for no other reason than bias, describes intelligent design in its own advertisements as "creationism."
 Scope and definition
The theory of evolution by natural selection deals only with the question of how organisms develop and form new species. Logically it can have nothing to say about the origin of the universe or the origin of life. It appears that some of the more, shall we way, scientifically-minded believers in ID attempt to constrain themselves similarly and claim no more than
God somebody is controlling evolution. Others however go further and claim that ID explains not only the origin of life but even the origin of the universe. This expansion in the claimed scope of the theory is probably caused by two things:
- If you see ID as a code word for "God" then the temptation to ascribe all of existence to "ID" is very strong.
- There is a common misconception among fundamentalists about what evolution actually is. For many, any scientific theory is an example of evolution and, to compete, ID must be capable of including anything which they erroneously believe evolution includes.
There is also a difference of opinion about what is actually involved biologically in ID. Again, for the more scientifically-minded it is simply evolution which is guided by God and common descent is fully accepted. For the more fundamentalist believers it is equivalent to progressive creationism in which complete new species are periodically created by
God someone. It is patently absurd for something which is presented as a scientific theory to be so lacking in any clear definition of scope and definition. (A reader who takes a close look the pro-ID description of Expelled will notice a number of these contradictions.) The contradictions exist as a consequence of the fact that ID attempts to include so many creationist ideas under the guise of science.
During an interview with R. C. Sproul, Ben Stein defined intelligent design as the "hypothesis" that "an all-powerful designer" created the universe, including living things in their present forms. John G. West and Casey Luskin have compared this hypothesis to the theory of evolution by means of natural selection. They have concluded that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." They refer to their conclusion as "the scientific theory of intelligent design."
Does their conclusion transform the intelligent design hypothesis into a "scientific theory"? No. A scientific theory, by its own merit, cannot be based on "all-powerful designers" or other supernatural causes (unless their existence can be shown by evidence). Their conclusion that intelligent design is the "best" explanation is an example of a propaganda technique named "assertion."
 Scientific evaluation
An outstanding issue of intelligent design is what mechanism the hypothesized "designer" uses to initiate design diversity. According to the theory of evolution, this mechanism is genetic mutation resulting from environmental stresses and point mutations caused by the cellular chemical environment. As of this time intelligent design supporters have yet to offer a plausible mechanism to which diversity can be attributed that differentiates from the mechanisms listed by the theory of evolution. As such the intelligent design proponents have yet to offer any empirical evidence to support the claim of a designer.
ID proponents such as Michael Behe promote theories such as "irreducible complexity" as evidence for their ideas. Irreducible complexity posits that there are certain organs and structures found in nature that have no convincing gradual evolutionary pathway, and are too complex to have come about in whole by chance. These ideas are hotly disputed (or dismissed as non-science) by scientists, but regardless of their truth value they do not constitute evidence for an intelligent designer. Proponents of intelligent design make an assumption unwarranted by the evidence in that their logic goes along the lines of "The origins and diversity of the species cannot be accounted for by evolution and natural selection alone, therefore there must have been a designer involved."
The very lack of positive scientific evidence suggesting that there is a designer involved in creating life raises the question of how the design hypothesis came about. Opponents of the design hypothesis would suggest that proponents are religiously motivated, and that their ideas are not about understanding how life came to exist but rather about promoting a particular religious world view as espoused in the Wedge Document.
There has also been no attempt to specify the periodicity of the miraculous interventions by the hypothesized "intelligent designer". In other words, the hypothesis does not state if the miraculous interventions take place annually, monthly, daily, or only when the designer feels that miraculous intervention is necessary.
ID proponents have yet to demonstrate that their idea is even remotely scientific by identifying what they believe could falsify it.
In fact, we await with interest any submission from supporters of this concept which would elevate it to the realms of science. Our article on what could disprove intelligent design remains embarrassingly void of valid arguments.
Slightly better educated supporters of ID sometimes complain that the theory of evolution lacks any mention of, or generally accepted hypothesis about, abiogenesis. It is of interest, however, that versions of ID which pretend to be science also lack any such mechanism - though the unstated assumption is that it was the work of god.
The objection also betrays a fundamental misunderstanding of the theory of evolution, which does not propose an explanation of how life started. It merely describes what happens after some form of life is extant.
