How do Intelligent Design People act?

Yes, just like it is possible to pursue astrology using the scientific method. Unfortunately for them, they both do badly.Unfortunately, "ID People" tend to ignore these problems and proclaim victory anyway. Occasionally they'll recant, but it often takes a lot of time and effort to get them to accept even rudimentary mistakes. Not usually by high school teachers, for obvious reasons. However, evolutionary biologists do use this method (though the method you describe is obviously simplified), and some of them teach at university.

They construct an experiment and make a prediction based on their hypothesis, then run the experiment and see if the results match what they expected. Pretty much how any scientific test works.I carried out one such test in Message 17 if you wanted a specific example, but you just go read some evolutionary biology science papers - they are filled with more more precise tests than that. Either way, you need to go to a different thread to get into detail.

I made a summary of ID over the course of 2006 which might be of interest to posters here A year in ID (2006)It includes the beginning of acceptance of common descent from the ID group, premature claims of the destruction of the neo-synthesis of evolution, accusations of Darwinian fascism as a reason no research is being carried out (as well as claims to the 'fact' that they had spent $4,000,000 on research!?).And lets not forget making an animation of Judge Jones with fart noises. That was important ID work.
