ID Garbage: CSI as Non-Computability

An alert reader pointed me at a recent post over at Uncommon Descent by a guy who calls
himself “niwrad”, which argues (among other things) that life is
non-computable. In fact, it basically tries to use computability
as the basis of Yet Another Sloppy ID Argument (TM).

As you might expect, it’s garbage. But it’s garbage that’s right
up my alley!

It’s not an easy post to summarize, because frankly, it’s
pretty incoherent. As you’ll see when we starting looking
at the sections, niwrad contradicts himself freely, without seeming
to even notice it, much less realize that it’s actually a problem
when your argument is self-contradictory!

To make sense out of it, the easiest thing to do is to put it into the
context of the basic ID arguments. Bill Dembski created a concept called
“specified complexity” or “complex specified information”. I’ll get to the
definition of that in a moment; but the point of CSI is that according to
IDists, only an intelligent agent can create CSI. If a mechanical process
appears to create CSI, that’s because the CSI was actually created by an
intelligent agent, and embedded in the mechanical process. What our new friend
niwrad does is create a variant of that: instead of just saying “nothing but
an intelligent agent can create CSI”, he says “CSI is uncomputable, therefore
nothing but an intelligent agent can create it” – that it, he’s just injecting
computability into the argument in a totally arbitrary way.

Another Cantor Crank: Representation vs. Enumeration

I’ve been getting lots of mail from readers about a new article on Google’s Knol about Cantor’s diagonalization. I actually wrote about the authors argument once before about a year ago.

But the Knol article gives it a sort of new prominence, and since we’ve recently had one long argument about Cantor cranks, I think it’s worth another glance.

It’s pretty much another one of those cranky arguments where they say “Look! I found a 1:1 mapping between the natural and the reals! Cantor was a fool!”

Shameful Innumeracy in the New York Times

I’ve been writing this blog for a long time – nearly four years. You’d think that
after all of the bad math I’ve written about, I must have reached the point where
I wouldn’t be surprised at the sheer innumeracy of most people – even most supposedly
educated people. But alas for me, I’m a hopeless idealist. I just never quite
manage to absorb how clueless the average person is.

Today in the New York Times, there’s an editorial which talks about
the difficulties faced by the children of immigrants. In the course of
their argument, they describe what they claim is the difference between
the academic performance of native-born versus immigrant children:

Whereas native-born children’s language skills follow a bell
curve, immigrants’ children were crowded in the lower ranks: More than
three-quarters of the sample scored below the 85th percentile in English
proficiency.

Scoring in the 85th percentile on a test means that you did better on that
test than 85 percent of the people who took it. So for the population as a
whole
, 85% of the people who took it scored below the 85th percentile –
by definition. So, if the immigrant population were perfectly matched
with the population as a whole, then you’d expect more than 3/4s the
score below the 85th percentile.

As they reported it, the most reasonable conclusion would be that on the
whole, immigrant children do better than native-born children! The
population of test takers consists of native-born children and immigrant
children. (There’s no third option – if you’re going to school here, either
you were born here, or you weren’t.) If 3/4s of immigrant children are scoring
85th percentile or below, then that means that more than 85% of
the non-immigrant children are scoring below 85th percentile.

I have no idea where they’re getting their data. Nor do I have any idea of
what they thought they were saying. But what they actually said is a
mind-boggling stupid thing, and I can’t imagine how anyone who had the most
cursory understanding of what it actually meant would miss the fact that
the statistic doesn’t in any way, shape, or form support the statement it’s
attached to.

The people who write the editorials for the New York Times don’t even
know what percentiles mean. It’s appalling. It’s worse that appalling – it’s
an absolute disgrace.

Dembski Stoops Even Lower: Legal Threats to Silence a Critic

For those who have slightly better memory of recent events than an average
gerbil, you’ll surely remember that not too long ago, the Intelligent Design
folks, with the help of Ben Stein, put together a whole movie about how
evilutionists are all a bunch of evil fascists, out to silence the poor,
hard-working IDers.

You’ll also remember that Bill Dembski has been talking up the fact that
he’s got two peer reviewed papers allegedly about intelligent design. So,
you’d think that after complaining about being locked out of the debate,
now that he has some actual papers to talk about, he’d be eager to, well,
talk about them!

Yeah, right. As it turns out, debate is the last thing that Bill
wants. When someone took a good look at one of his papers, and
posted a critique, Bill’s response was the threaten to sue them for
copyright violation. Knowing how utterly trustworthy the Disco gang
is, I’ve got a screen-capture of the post with the threat below the fold, in
case they try to change history by deleting it.

Berlinski – still pompous, still wrong.

An anonymous tipster sent me a note to let me know that on one of the Disco
Institute’s sites, my old pal David Berlinski has been arguing that all sorts of
famous mathematicians were really anti-evolution.

I’ve written
about Berlinski before.
In my opinion, he’s one of the most pointlessly
arrogant pompous jackasses I’ve ever been unfortunate enough to deal with. He
practically redefines the phrase “full of himself”.

This latest spewing of him is quite typical. It is mostly content free –
it consists of a whole lot of name-dropping, giving Berlinski a chance to talk
about all of the wonderfully brilliant people he’s close personal
friends
with. And, quite naturally, his close personal friends have told
him all sorts of things about what other famous mathematicians
really thought about evolution.

Free Energy From Air? Sorry, no.

After the
fiasco
that was my flame against the downwind faster than the wind
vehicle, you might think that I’d be afraid of touching on more air-powered
perpetual motion. You’d be wrong :-). I’m not afraid to make a fool of myself
if I stand a chance of learning something in the process – and in this case,
it’s so obviously bogus that even if I was afraid, the sheer stupidity here
would be more than enough to paper over my anxieties. Take a look at this –
the good part comes towards the end.

The Hallmarks of Crackpottery, Part 1: Two Comments

Another chaos theory post is in progress. But while I was working on it, a couple of
comments arrived on some old posts. In general, I’d reply on those posts if I thought
it was worth it. But the two comments are interesting not because they actually lend
anything to the discussion to which they are attached, but because they are perfect
demonstrations of two of the most common forms of crackpottery – what I call the
“Education? I don’t need no stinkin’ education” school, and the “I’m so smart that I don’t
even need to read your arguments” school.

Sloppy Dualism on Bad Astronomy

In the history of this blog, I’ve gone after lots of religious folks. I’ve mocked
lots and lots of christians, a few muslims, some Jews, some newagers, and even one
stupid Hindu.

Today, I’m doing something that’s probably going to get me into trouble
with a lot of readers. I’m going to mock a very well-known atheist. No, not PZ.
As much as I disagree with PZ, as far as I can tell, he’s consistent about his
worldview.

Over at Bad Astronomy, Phil Plait has been a major voice for skepticism and
a vocal proponent of atheism. He has, quite rightly, gone after people of all stripes
for foolishness and silly supernaturalism. He’s frequently talked about how silly he
thinks religion is. All well and good.

But Phil just really
screwed up
. And I’ve got to call him on it.

Bill Dembski Weasels Under Even My Low Expectations

A brief disclaimer before I start. I do not read Uncommon Descent. I didn’t check
it before writing my post yesterday. So I didn’t know about the content of Dembski’s
post there that I’m about to write about, until I saw Bob O’H‘s comment on my post this morning.

Yesterday, I explained how he used Dawkins’ “weasel” experiment as an example
of his and Marks’ approach to quantifying the information in search. I said that
it was a lousy example for what it was purportedly being used to demonstrate. And I
theorized that he wanted to claim peer-review approval for his “critique” of Dawkins.

Unbeknownst to me, before I even wrote those words, Dembski had already
done that, over on UD (as usual, I refuse to link to UD; you know where to find them
if you really must):

P.S. Our critics will immediately say that this really isn’t a pro-ID article but that it’s about something else (I’ve seen this line now for over a decade once work on ID started encroaching into peer-review territory). Before you believe this, have a look at the article. In it we critique, for instance, Richard Dawkins METHINKS*IT*IS*LIKE*A*WEASEL (p. 1055). Question: When Dawkins introduced this example, was he arguing pro-Darwinism? Yes he was. In critiquing his example and arguing that information is not created by unguided evolutionary processes, we are indeed making an argument that supports ID.

Umm… Bill, the reason that your critics say it isn’t a pro-ID article is because
it doesn’t talk about intelligent design. It’s a rather dull math paper
about how to quantify the information content of a search algorithm that that
allows it to perform well in a particular kind of search domain.

And the paper doesn’t critique Dawkins’ experiment at all! It
describes a variant of the “Weasel” experiment as an example of how
to quantify the landscape information in a partitioned search. It doesn’t
critique that at all; it just presents a straightforward analysis of it.
So it doesn’t actually critique anything.

But more importantly: as people have explained to you hundreds of times by now, Dawkins’ didn’t use locking. Dawkins’ search algorithm was not
partitioned search
. In fact, the algorithm that Dawkins’ used can’t be
modeled as a partitioning search at all.

So, as usual… Dembski is a liar. At this point, there’s just no way to
excuse him. I don’t consider him to be a particularly competent mathematician – but
ignorance and incompetence are no longer an adequate explanation of his rubbish. He’s
had the locking error pointed out to him numerous times; he’s had the difference explained
to him, demonstrated to him, proven to him numerous times – but he still keeps
harping on the incorrect version of the experiment, because it’s an easier target.

Disco Goes Digital

It sometimes seems like every day, some “intelligent design” bozo comes out with
another book rehashing the same-old crap. I usually ignore it. But this time, I felt
like the promotional materials for one of the new books really stepped right into my
part of the world, rhetorically speaking, and so I figured I should give it a
quick smackdown.

The book in question is Stephen C. Meyer’s “Signature in the Cell”. Meyer’s argument
basically comes down to one that is seems like we’ve heard and dealt with a thousand times already. There’s stuff in the cell which looks kinda-sorta like a machine if you look at it in the right way, and since machines were designed, therefore so were cells.

If that’s all he said, I’d just ignore him. Why rehash the same old shit? But no. This time, the DI needed to add a youtube video, which makes some amazingly strong, unsupported claims.

The official description of this is “This animation shows how the digital information encoded in DNA directs protein synthesis inside the cell and provides a unique look at the evidence for intelligent design as described in Dr. Stephen C. Meyers book Signature in the Cell”. The soundtrack, if you pay attention to it, repeats that claim several times in several ways: that DNA is specifically digital information, and that therefore the processes that operate on DNA are effectively digital computations, and since everyone knows that a digital computer required intelligent humans to design it, it’s impossible that the “digital computer” in the cell evolved.
