Wesley R.

The title here is "Unacknowledged Errors"; part of the reason for this thread is to watch for when, if ever, the errors in the Marks and Dembski paper become acknowledged by the authors. The Marks and Dembski essay, in PDF format: Quote Abstract How do genetic systems gain information by evolutionary processes? Schneider [14] asks this question and then purports to answer it by simulating the evolution of nucleotide binding sites with an algorithm called ev. Upon examination, ev's structure is algorithmically equivalent to the inversion of a perceptron neural network. We show that ev is able to evolve binding site locations only because it is prestructured to do so. The difficulty of the problem is 131 bits. The perceptron search structure adds about 122.2 bits of information, leaving only about 8.8 bits to the search procedure. Although the perceptron structure smuggles in an enormous amount of information, ev squanders it with the evolutionary search. The evolutionary algorithm in ev required over 45,000 fitness queries to achieve success. Based on query count, repeated random queries outperform the evolutionary algorithm by over 10,000%. The simulation of evolutionary processes using ev illustrates a larger problem in interpreting the results of evolutionary simulations. Interpretations of simulation results, if they are to be credible and inspire confidence, should (a) identify the inherent difficulty of solving the problem and, (b) measure the amount of information about the solution provided by the search structure and the search procedure. Tom Schneider responds to criticism: Quote Considering 439 queries as 3 orders of magnitude, Dembski's estimate is off by about 13 orders of magnitude. Schneider provides several different methods to arrive at the conclusion that Marks and Dembski are off, way, way off. So, how long will the erroneous claims of Marks and Dembski be headlining "Baylor's Evolutionary Informatics Laboratory"? -------------- "You can't teach an old dogma new tricks." - Dorothy Parker

For anyone interested, the error in the results can be traced to an easily discovered bug in one of their MATLAB scripts (now removed from their site).  The error is so big that putting a number on it is dicey.  My method of estimating it is different than Tom's, and I come up with 20 orders of magnitude as opposed to Tom's 13 orders of magnitude. It should also be noted that the erroneous results are still reported in one of M&D's other papers, and that both Marks and Dembski have repeated their now-falsified conclusion in interviews.  Also, Gil Dodgen included the erroneous results in one of his UD articles. -------------- -- Rob, the fartist formerly known as 2ndclass

From wikipedia: Quote A universal probability bound is a probabilistic threshold whose existence is asserted by William A. Dembski and is used by him in his works promoting intelligent design. It is defined as "A degree of improbability below which a specified event of that probability cannot reasonably be attributed to chance regardless of whatever probabilitistic resources from the known universe are factored in."[1] The notion that such a degree of improbability actually exists, and is specifically 1 in 10^50, is known in the informal Creationist literature as Borel's Law.[2] What does a miss of 65 orders of magnitude tell us about, erm, god? -------------- "Richardthughes, you magnificent bastard, I stand in awe of you..." : Arden Chatfield "You magnificent bastard!

Quote But in a recent guest column, Mark Ramsey, the founder of Texans for Better Science Education, called the dispute "a giant leap backward" for Baylor. "This censorship is based not on poor scholarship or bad data but on a disagreement about the research's conclusions. The conclusions were not deemed to be particularly favorable to the notion that Darwin was right and no intelligence was required in the creation of the world and everything in it," he wrote. This just goes to show how commentators like Mark Ramsey have no clue whether any of this stuff is based on good, bad, or no data at all. The "ev" critique paper was based on bogus data. Garbage in, garbage out. Actually, GIGO is a step forward for Dembski, who for years has been stuck in "garbage out" mode. Actually trying to pay some attention to data at all probably must be credited to Robert Marks. This was the stuff that was supposed to wipe the MSU Devolab off the map? -------------- "You can't teach an old dogma new tricks." - Dorothy Parker

I entered the following comment over at William Brookfield's weblog in the thread where he whines about critics not responding on his schedule to EIL online essays. Quote The "Unacknowledged Costs" paper critiquing Schneider's "ev" has unacknowledged errors. The conclusions in another of the essays are tainted by reliance on the bogus numbers in the "ev" critique. Tom Schneider had responses up back near the beginning of August in his usual place for such responses. It doesn't seem that Brookfield's search could be described as assiduous. I've been awaiting substantive replies from Dembski on several of my critiques for years. Will Brookfield draw a conclusion about Dembski from that datum? Wesley R.

Quote Of course, looking at another of the papers that is listed on the EIL site, I noticed that it includes a clear error that I informed Dembski of long ago. In fact, today is the seventh anniversary of the unregarded notification of that error. This is the standard for unacknowledged errors that Dembski has set.

Wesley R. Elsberry Posts: 4991 Joined: May 2002 (Permalink) Posted: Oct. 09 2007,12:42    I've entered another comment at the ICON-RIDS site...   Quote Amusingly enough, today turns out to be the seventh anniversary of my notifying William Dembski of errors in his description of Dawkins's "weasel" program. If Dembski had heeded that (much less acknowledged it), he might have restricted the damage to the online text originally containing the error. Instead, it now contaminates at least one of his published books, and can even be seen in one of the two remaining EIL essays online. If the paper which is claimed to be under review does get published with the error in it, I look forward to publishing a letter noting the error and its long, long history in the same publication. While Dembski's attitude toward plain errors discovered by critics seems to be ramping up the recalcitrance, it could be the case that Dembski's co-author, Robert Marks, may not wish to take that ride. Time (and plenty of it) may tell. Wesley R. Elsberry -------------- "You can't teach an old dogma new tricks." - Dorothy Parker

Honestly, I don't see how Dembski can avoid saying something.  The errors are so widely publicized and so well described that even I -- an English professor -- can understand them.  Further, what remains of Dembski's credibility is entirely hung on the thin nail of his collaboration with Marks.  Is it possible that he'll just keep his fingers in his ears?  Am I being naive? -------------- "I am not currently proving that objective morality is true.

Wesley R. Elsberry Posts: 4991 Joined: May 2002 (Permalink) Posted: Oct. 09 2007,16:23    I've emailed Robert Marks to inform him that the EIL paper that relies upon critiquing Dawkins's "weasel" program has a problem. Dembski and Marks say partitioned search contributes a lot of information to "weasel". The problem? "Weasel" does not use partitioned search. This is the upshot of the seven-year-old notification I sent Dembski. I've very clearly said that I plan to submit a corrective letter if they manage to get the paper published as it stands.

Marks just pulled in a NSF grant, for example.  Unlike Dembski, Marks has a career. I just don't see Marks flushing his reputation down the crapper for the likes of Dembski, unless his ambition is to run against Behe for Mayor of Cranksville. I vote he'll pull the paper and the EIL will quietly become boojumized.

The heavy lifting was done by Schneider, Secondclass, and vun Kannon. It's gratifying, though, that something I noted so long ago may be of great relevance to that other paper on the EIL site. I'm still somewhat amazed by the coincidence on dates. I had a draft of the PT post put together last week, got some comments for changes from Rob last Wednesday or so, and got a little time to finish it off today. When vun Kannon's comment sent me off to the EIL website again, that's when I realized that the other paper was passing along that tired old error of Dembski's. Then I looked up my email and discovered the date match. -------------- "You can't teach an old dogma new tricks." - Dorothy Parker
