If something is designed, what is left for the scientist to do, right? For one thing, it would stop unnecessary millions of dollars going for research to generate stories to account for the origin of the eye (as one example) through a gradual succession of undirected natural causes.
Second, science could move immediately to reverse engineering: investigating how objects are designed, how they work, and how to create applications of the design to improve society. Intelligent design application is human intelligence determining what a higher Intelligence has already done.
As a result, intelligent design is not a science-stopper. It can foster inquiry where traditional evolutionary approaches have obstructed it. For example, evolution discourages looking for a function for “junk DNA” because it is alleged to only be the remnant of a past evolutionary process. Design encouraged looking for a function and nearly all formerly “junk DNA” is now known to have a function.
Another example is that evolution said the human appendix was a remnant of past evolution without any current function. Design said, “No” and encouraged further study. Indeed, functions for the appendix have since been found which prove it to be an important organ.
