First off, it bears repeating that whatever differences there may be between SETI and ID, the principle remains.
(((Mick: 1. Mathematical models of what kinds of signal are NOT intelligently designed.. ___ID, on the other hand, has no clear model of what biological "noise" looks like, so ID researchers are unable to falsify a claim that a signal is intelligent.)))
This shows a lack of knowledge or a lack of understanding of ID. There have been very clear and specific criteria laid out very clearly.
(((2. Mathematical models of what kind of signal IS intelligently designed ___ID researchers, on the other hand, do not have a model of what intelligent design in the biological world would look like. )))
Of course they do. I suggest you study up on the subject.
(((3.3. An empirical research program based on falsification ___ID researchers, on the other hand, are not engaged in gathering empirical data from the world which can be used to falsify the hypothesis of intelligent agency.)))
==> The data they use is well known. If you learn what the assertions are, you can attempt to falsify them. In general, those who could have tried, have instead avoided trying, using the ruse of rejecting the idea based on either the implications, or based on some theological point.
