Regarding actual tests of the Explanatory Filter (EF)…
I’d like to ponder this for a liddle bit.
Dembski sez (p. 96 of Design Revolution: “Where direct, empirical corroboration is possible, design actually is present whenever specified complexity is present.”
So far all tests of the EF have been done on human design. Extending the EF to non-human design may not be valid. Quite how we would get an agreed example of non-human design presents a problem for ID.
As far as I am aware almost all tests of Dembski’s EF were done in the early days of ID. I will admit to having done a couple of examples of the EF myself:
here and
here. I am not aware of any recent developments of the EF to automatically process RNA or DNA sequences, to take an obvious example. It is absurdly easy to produce designed and non-designed DNA or RNA sequences for testing. There are even examples of living organisms with designed DNA sequences in them - many genetic engineering laboratories write their names in the DNA of the organisms they produce to mark them in case of dispute.
As a simple example, here are two RNA sequences, one designed and the other not:
Code:
Designed: ACUCAUAUAUCCUAGAGAAAUGCCUAAAUUUCGUGAGACCAAAGUAUCGGUAACCAGGAU
Random : AUGUAUAAGUGGCCCUUUCCAGCUAAGAUUGCAGUGCUUAACACAACAAGAUUGAUCUUG
The ID side need to work on the EF so that we can automatically apply it to RNA sequences such as the two above.
ID therefore asserts that we can infer design any time we find SC, even when we don’t have access to the causal history.
We do not always have full access to the causal history, nevertheless we can make reasonable assumptions about it. So far ID has failed in all of its attempts to show that certain organs, or organelles, could not have evolved. We do not know who Seth’s wife was, nevertheless we can reasonably infer her existence from the genealogies in Genesis. Unless we have some very strong evidence to the contrary we can reasonably assume that Seth fathered Enosh in the usual way. ID needs similarly strong evidence to overturn the reasonable assumption that evolution produced the whole variety of life on earth from simple beginnings about 4.5 billion years ago.
So this suggests two lines of attack against ID. First, you attack the premise. Set up experiments in which something with a known causal history is only apparently designed.
Snowflakes are a good example, and one where the known causal history is of crucial importance. Without a knowledge of their causal history it is possible that snowflakes, with their high degree of symmetry, would register as designed.
Let the ID guys apply the EF to it, and, after they make their design inference, bring out the proof that it was produced only by chance and necessity.
That requires a lot of work on the ID side to refine and develop the EF. I have not seen much development of it since Dembski first proposed it some years ago. There has been more recent work from the ID side on Behe’s IC than there has been on Dembski’s EF.
Second, with respect to actual biological phenomena, you produce the causal history which shows how it was produced by purely natural processes.
Unlikely, because you are asking for more detail than is available. We may well all be descended form Adam, but none of us can produce a precise genealogy, complete with birth certificates, proving our descent from Adam.
