That Dembski uses 'standard' probablities does not help the fact that
he is mostly arguing a biological strawman.
Let's look at this from a different perspective. According to Dembski
most any protein larger that about 1100 the designer will be quite
busy..
As Wesley Elsberry and Jeffrey Shallit in Information Theory,
Evolutionary Computation, and
DembskiÕs ÒComplex Specified InformationÓ 2003 argue http://
www.talkreason.org/articles/eandsdembski.pdf
<quote>Even if DembskiÕs intuition concerning the values he assigned
to these factors was proven to be uncannily precise, there remains
an interesting observation concerning the application of a
perturbation probability to the calculation of porig for a particular
protein. Dembski utilizes an analogy of a supermarket stocked with
plenitude of different grocery products.
Each of those products, he argues, may have its own porig value [19,
p. 301]. Given DembskiÕs
values for the perturbation tolerance and identity factors, what one
finds without much
difficulty is that porig for any individual protein of length ³ 1153
is less than DembskiÕs
Òuniversal small probability.Ó Further, any collection of proteins
with a combined length
³ 1153 also has porig less than DembskiÕs Òuniversal small
probability.Ó Dembski elsewhere
tags biological function as a sufficient stand-in for
Òspecification.Ó The result is that, using
DembskiÕs proffered values and equations, any functional protein of
length ³ 1153 has CSI
and must be considered to be Òdue to design.Ó This is already a low
bar for finding CSI
in biological systems, but the Òuniversal small probabilityÓ is not
in any sense a threshold.
Dembski merely argues that a probability below the Òuniversal small
probabilityÓ obviates
the need to justify a Òlocal small probability.Ó By doing so, many
shorter proteins may also
be found to have CSI and be classed as Òdue to design.Ó A Dembskian
designer intervening
in biology would appear to be exceedingly busy over the course of
lifeÕs history.

What van Till argues, and what Dembski does not address is that the
processes mimicked by Dembski have NO relevance to how things
actually happen and or evolutionary processes.
One cannot blame Dembski for his unfamiliarity with biology but one
should realize that whenever Dembski speaks about such issues, one
should take care to ask the question if Dembski's portrayal of the
scenario relevant from a biological perspective.
Both van Till and Miller have pointed out much of the same problems
with Dembski's arguments, as have others:
In his response to Miller Dembski argues
<quote>But in fact they do. My point in section 5.10 was not to
calculate every conceivable probability connected with the stochastic
formation of the flagellum (note that the Darwinian mechanism is a
stochastic process). My point, rather, was to sketch out some
probabilistic techniques that could then be applied by biologists to
the stochastic formation of the flagellum. As I emphasized in No Free
Lunch (2002, 302): "There is plenty of biological work here to be
done. The big challenge is to firm up these numbers and make sure
they do not cheat in anybody's favor."</quote>
So by calling Darwinian mechanisms a stochastic process, one can thus
take a strawman version of a stochastic process and say see... it
won't work. But remember that a in Dembski speak, while looking at
'stochastic formation' it was purely based on chance alone. No
attempt to take into consideration biologically relevant data. There
is indeed much work to be done especially since the data surely
cheated in favor of ID. As such at most we can conclude is that
according to Dembski's flawed strawman, evolution and indeed protein
formation is impossible. In other words, we have a very busy designer
focusing on such irrelevant concepts as putting proteins in their
right location etc...
Is that the kind of designer we have in mind?
