Intelligent design can't be studied scientifically, because it is not science. There is no way to test it.

According to the NAS, intelligent design is not science because it cannot be tested by the scientific method. Intelligent design does “not offer hypotheses that are subject to change in light of new data, new interpretations, or demonstrations of error.” Rather, the concept makes observable data inferior to doctrine. Intelligent design reverses the scientific process by setting forth an assumed conclusion — an intelligent designer is responsible for the universe — and only seeking evidence in support of this conclusion. In contrast, a scientific theory “always remains subject to the possibility of rejection or modification in light of new knowledge.”
