That's a hypothesis. After you propose a hypothesis, you're supposed to go on to test it. Nothing in the rest of what you quote proposes a way of testing this hypothesis.
There are no experimental tests to determine either complexity or specification. As Dembski defines it, complexity is just improbability. No one knows how to estimate (much less measure) the probability of a complex (in the normal sense) feature arising by evolution, for example.
There is no logical connection between CSI and irreducible complexity. "Complex" here doesn't mean what it does for Dembski, and there's no reason that an irreducibly complex system has to have any particular amount of CSI.
If this is really how ID researchers proceed, then we should not be wasting our time considering their conclusions. Nothing in this logical train makes the slightest bit of sense.
There are experimental tests for CSI done by forensic scientists, fire inspectors, and people at SETI to name a few. The design inference by Dembski is validated all the time. It's only when people use unspecified complexity or specified simplicity are there false positives.
"The term “specified complexity” goes back at least to 1973, when Leslie Orgel used it in connection with origins-of-life research: “Living organisms are distinguished by their specified complexity. Crystals such as granite fail to qualify as living because they lack complexity; mixtures of random polymers fail to qualify because they lack specificity.” See Orgel, The Origins of Life (New York: Wiley, 1973 ), 189."

Dembski said this about the work of Hubert Yockey, Robert Sauer, Peter Rüst, Paul Erbrich, Siegfried Scherer, and Douglas Axe:
"I'm not enlisting these individuals as design advocates but merely pointing out that methods for determining specified complexity are already part of biology."

We can't go back in time to do experimental tests in biology, so a vera causa is used as an inference to the best explanation. Meyer laid out a vera causa in 'The Signature in the Cell'. Invariably intelligent agents cause long sequences of complex specified information. Using a known cause to explain past events was used by Darwin too. Using that known cause to explain the CSI in DNA is an inference to the best explanation. It can be falsified by showing undirected natural causes making long sequences of CSI.
Also, there is a connection between CSI and irreducible complexity. The irreducibe element of irreducible complexity is a specified pattern.
