The Discovery Institute started the intelligent design movement bankrolls it and is it's paycheck. So...Wow, this ID argument is just going on and on, and in circles too. Let me put in my two cents.
The way I see it, creationism and ID are different things. ID is associated with the cause of life. Creationism is associated with the method of life.
A person can believe in ID as a cause and evolution as a method, or they can believe in ID as a cause and creationism as a method. Or they can believe in evolution as a cause and method. It depends on what seems to make more sense.
No cause is actually supported by scientific evidence. Even evolution as a cause, is not supported by actual evidence, but rather by mathematical correlations, analogy and theoretical ideas.
But when it comes to the method, evolution is supported by evidence, especially micro evolution, and in many cases it can be argued that micro evolution becomes macro evolution in the long run. Creationism as a method however, is not supported by any scientific evidence.
The Discovery Institute tries to use ID and creationism interchangeably. They try to assert creationism as a cause and method. Their particular brand of creationism is that the Christian god done it. To base ones definitions on the Discovery institute would be nothing but a sad waste of time battling a strawman anyway.
All this is meaningless the DI is the cause of ID so DI=ID
add the wedge document ,
DI+ID+Wedge Document= Intelligent Creationism
