C9: Misuse of an inductive argument by the assertion of no false positives. also CI111.1 Specified complexity is a reliable criterion for detecting design. from the index of creationist claims by Mark Isaak
Hat tip to Wesley Elsberry
Biologists worry about attributing something to design (here identified with creation) only to have it overturned later; this widespread and legitimate concern has prevented them from using intelligent design as a valid scientific explanation.
Though perhaps justified in the past, this worry is no longer tenable. There now exists a rigorous criterion—complexity-specification—for distinguishing intelligently caused objects from unintelligently caused ones.

Compare this with
I argue that we are justified asserting specified complexity (and therefore design) once we have eliminated all known material mechanisms. It means that some unknown mechanism might eventually pop up and overturn a given design inference.
These two claims seem to be contradictory, so which one should we take as relevant? The one which claims that there exists a rigorous mathematical criterion which reliably (no false positives) detects design? Or the one which admits that there is the possibility of false positives, rendering the reliability criterion of this ‘rigorous concept’ invalid and making the concept of the eliminative filter useless
“On the other hand, if things end up in the net that are not designed, the criterion will be useless.”
