In a comment to a recent thread I made the following challenge to the materialists:

Show me one example – just one; that’s all I need – of chance/law forces creating 500 bits of complex specified information. [Question begging not allowed.] If you do, I will delete all of the pro-ID posts on this website and turn it into a forum for the promotion of materialism. . . .

There is no need to form any hypothesis whatsoever to meet the challenge. The provenance of the example of CSI that will meet the challenge will be ACTUALLY KNOWN. That is why I put the part about question begging in there. It is easy for a materialist to say “the DNA code easily has more than 500 bits of CSI and we know that it came about by chance/law forces.” Of course we know no such thing. Materialists infer it from the evidence, but that is not the only possible explanation.

Let me give you an example. If you watch me put 500 coins on a table and I turn all of them “heads” up, you will know that the provenance of the pattern is “intelligent design.” You do not have to form a chance hypothesis and see if it is rejected. You sat there and watched me. There is no doubt that the pattern resulted from intelligent agency.

My challenge will be met when someone shows a single example of chance/law forces having been actually observed creating 500 bits of CSI.

R0bb responded not by meeting the challenge (no surprise there) but by suggesting I erred when I said CSI can be “assessed without a chance hypothesis.” (And later keith s adopted this criticism).

I find this criticism odd to say the least. The word “hypothesis” means:

A proposition . . . set forth as an explanation for the occurrence of some specified group of phenomena, either asserted merely as a provisional conjecture to guide investigation (working hypothesis) or accepted as highly probable in the light of established facts.

It should be obvious from this definition that we form a hypothesis regarding a phenomenon only when the cause of the phenomenon is unknown, i.e., has not been actually observed. As I said above, in my coin example there is no need to form any sort of hypothesis to explain the cause of the coin pattern. The cause of the coin pattern is actually known.

I don’t know why this is difficult for R0bb to understand, but there you go. To meet the challenge, the materialists will have to show me where a chance/law process was “actually observed” to have created 500 bits of CSI. Efforts have been made. All have failed. The now defunct infinite monkeys program being just one example. It took 2,737,850 million billion billion billion monkey-years to get the first 24 characters from Henry IV part 2.

 

UPDATE:

R0bb  responds at comment  11:

That’s certainly true, but we’re not trying to explain the cause of the coin pattern. We trying to determine whether the coin pattern has CSI. Can you please tell us how to do that without a chance hypothesis?

To which I responded:

1. Suppose you watched me arrange the coins. You see a highly improbable (500 bits) pattern conforming to a specification. Yes, it has CSI.

2. Now, suppose you and I were born at the same time as the big bang and did not age. Suppose further that instead of intentionally arranging the coins you watched me actually flip the coins at the rate of one flip per second. While it is not logically impossible for me to flip “all 500 heads,” it is not probable that we would see that specification from the moment of the big bang until now.

So you see, we’ve actually observed the cause of each pattern. The specification was achieved in scenario 1 by an intelligent agent with a few minutes’ effort. In scenario 2 the specification was never achieved from the moment of the big bang until now.

The essence of the design inference is this: Chance/law forces have never been actually observed to create 500 bits of specified information. Intelligent agents do so routinely. When we see 500 bits of specified information, the best explanation (indeed, the only explanation that has actually been observed to be a vera causa) is intelligent agency.

To meet my challenge, all you have to do is show me where chance/law forces have been observed to create 500 bits of specified information.

I didn’t say I wouldn’t investigate. I’ve been very clear about that.
Right, but I'm arguing that you can go straight from the 500-head observation to the conclusion that something fishy is going on. In other words, even if you couldn't investigate and couldn't repeat the trial, you would still be justified in concluding that the coin and/or the flipping weren't fair.
BUT you would need the same number of coins to be sure to force any other sequence of 500 Hs and Ts. You could force any sequence you want with the same approach.
Sure. That's why I wrote this:
We know that the under the fairness assumption, the probability of getting a “special” pattern is only n in 2^500, where n is the number of patterns that you would consider special.
The probability of each 500-flip sequence is the same. The "content" only matters for deciding whether the sequence falls into the "special" category or the "not special" category. The "special" category can be quite fluid. If I sit down at my computer and use it to generate a pseudorandom 500-flip sequence, and then proceed to run the actual 500-flip experiment, I will know something fishy is going on if I flip the same sequence that my computer just gave me. In other words, a completely random-looking sequence can become "special" simply because I choose to designate it as special. As long as the "special" category is small enough relative to the "not special" category, we can conclude that something fishy is going on every time we get a "special" 500-flip sequence.keith s

Joe, Dr Dembski has made a claim. It's up to a claimant to uphold and defend their position. As Dr Dembski has abandoned his position (for the most part) and now spends most of his time, as far as I understand it, teaching theology it would seem that the hypothesis presented in his 2005 paper is now an orphan dying a death of attrition and neglect. Regardless, biologists and mathematicians are under no obligations to provide anything to uphold or defend or explain their fields or views because of this one, defunct outpost. Dr Dembski planted a flag and then neglected to protect it. If you want to rally around it then it's up to you to find the evidence and prove its validity. Can you do that? Time to put up or shut up.Jerad

Our position has to match Dr Dembski’s definition?
LoL! It isn’t Dembski’s definition. Your position is the chance hypothesis. Deal with it.
Dr Dembski defined an assumption, a hypothesis without running it past evolutionary biologists (or mathematicians for that matter) and now you expect the biological world to even care? Do you realise how arrogant that sounds? I've already pointed out that natural selection is not a chance/random process. Perhaps if Dr Dembski wanted to come up with a viable model of evolutionary processes he should have spoken to some people who know those processes. I shall also point out that his paper has been reviewed by biologists and mathematicians and they found it to be incorrect in many ways. Maybe you should deal with that eh?
Dembski got it from peer-reviewed evolutionary biologists.
Did he speak to them or just use his own interpretations of their work? If he mis-interpreted their work then . . .
Natural selection does not operate by chance.
Sure it does. Just because the probability of being eliminated is not equal doesn’t mean it isn’t driven by chance
Too bad the entire filed of evolutionary biology disagrees with you. Maybe you should deal with that eh?
See this is why several of us are trying to figure out what kind of probability distribution you think P(T|H) is.
Then you should try to figure out what natural selection really is. It is a result that has chance components as inputs. The variation is all chance. What will be inherited is partly chance. What will be eliminated is also partly chance.
So, evolutionary biology should respond to a non-published, non-peer reviewed paper based on your mis-interpretation of natural selection?
You haven’t shown any ability at all…
Let them with eyes, see. Do you even know what a probability density function is? Without looking it up on Wikipedia.Jerad

Let’s put it this way: If every particle in the observable universe were a coin, you would still need about 10^70 such universes to have enough coins to get you to 500 heads. Now do you see why we can be certain, even after only one 500-flip trial, that something fishy is going on?
I didn't say I wouldn't investigate. I've been very clear about that. BUT you would need the same number of coins to be sure to force any other sequence of 500 Hs and Ts. You could force any sequence you want with the same approach. So, on a single trial of 500 flips, why wouldn't you say something fishy was going on when one of those other sequences shows up? Because some outcomes more closely match your expectation of roughly half Hs and half Ts? But a sequence of exactly alternating Hs and Ts would set off your alarm bells correct? So it's not just the proportion of Hs and Ts that might cause you consternation. It's the 'pattern' in the sequence as well. Let's say I got the following sequence of flips: HHHTHHHHTHHHHHTTTTTTTTTHHTTTTTTHHHHHTTTHHHHHTTTTTTTTHHHHHHHHHTTTTTTTHHHHHHHHHTTT and quite a lot more. Would that one make you go hmmmmmm? It sure would me. I'll tell you why if you wish. It's not because of the clumps of Hs and Ts, randomness is clumpy. How about this one? HHTTTTTTTHTTTTTTTTHHTTTTTTTTHTTTTTTTTHHTTTTTTTTHHHHTTTTTHHHHHHHHHTTTTHHHHH Also sets my pattern recognition bells a'ringing. People are good at spotting patterns but not at spotting randomness. So the patterns become suspicious when we think there shouldn't be any.Jerad

Jerad #147:
As I said before you can pretty much guarantee getting 20 Hs in a row by doing the following: Start with 2 million coins. Flip them all. Take out the ones that come out Ts. Repeat. By the time you get down to 1 coin left that coin should have 20 or more Hs in a row. If it were me I would carefully examine that coin but the mathematics is correct. If you use 2 million fair coins you can force 20 Hs in a row. (Thanks to Neil deGrasse Tyson for the idea.) 500 Hs in a row would take a lot more coins obviously. I’ll leave it up to the readers to figure out how many.
Let's put it this way: If every particle in the observable universe were a coin, you would still need about 10^70 such universes to have enough coins to get you to 500 heads. Now do you see why we can be certain, even after only one 500-flip trial, that something fishy is going on?keith s

So P(T}H) is just a conditional probability function- that is the probability of T given H, where H is are the chance hypotheses that our opponents need to but cannot provide.

If by H, they mean any proposed hypothesis, including evolution, then the calculation is not only intractable, but it is entailed also in phi_S, meaning the terms are no longer independent.

No Jerad, I am sick of discussing this with people who are obviously on some moronic agenda.
Just trying to see if you understand Dr Dembski's paper. I can see that you did eventually copy and paste a pertinent paragraph.
It is up to YOU to provide H- period. You can’t and you want to try to blame us.
We're not the ones that came up with the formulation!! Give me an example of the kind of chance hypothesis Dr Dembski is referring to.
P(T|H) is just ONE of several formulas by Dembski. It is not about calculating CSI. It is about using specification to provide a design inference.
P(T|H) is a conditional probability.
What I said: P= probability. T= the rejection region (of an event, object or structure) and H are the chance hypotheses. Your position = H And Jerad sed I was wrong…
Dr Dembski defines H in his paper. So I guess he provided it eh? And on page 18 Dr Dembski uses a different definition for T. Do you think they are equivalent?Jerad

More formally, the problem is to justify a significance level ? (always a positive real number less than one) such that whenever the sample (an event we will call E) falls within the rejection region (call it T) and the probability of the rejection region given the chance hypothesis (call it H) is less than ? (i.e., P(T|H) < ?), then the chance hypothesis H can be rejected as the explanation of the sample.

Jerad: Find me where in Dr Dembski’s paper it says that someone has to ‘provide’ the chance hypothesis. Absent anything else, we might suppose a uniform probability distribution, which is what kairosfocus and others who mess with it seem to be doing. We would appreciate it if they were explicit. If so, we can discuss William's Victorian house. If by H, they mean any proposed hypothesis, including evolution, then the calculation is not only intractable, but it is entailed also in phi_S, meaning the terms are no longer independent.Zachriel

I have now pointed out enough times that the transformation by log reduction allows us to access direct and statistical measures of information. Which, we do routinely observe, e.g. most readily in DNA and proteins.
`I am specifically interested in why you chose to replace P(T|H) in Dr Dembski's formulation with another term.
At this point, I have to view the continued harping on any number of cogently answered talking points (including the continued misrepresentation of the design inference process on signs, through rain fairy talking points and whatnot) as question-begging agit-prop message dominance tactics, that have nothing to do with serious thought on the merits, an important matter.
I'm not sure you've understood and interpreted Dr Dembski's work correctly.
As for Joe’s point, he is right to point out that the chance-driven theories do need to logically justify, articulate and empirically warrant their claims.
I don't believe you've properly interpreted Dr Dembski's work on this.
Let us not forget, that starts with the root of the tree of life, origin of living cells in Darwin’s pond or the like environment driven by the physics and chemistry at work. We do know a fair amount about that, and as design thinkers since Thaxton et al have pointed out, the thermodynamics and chemical kinetics are not favourable to blind chance and mechanical necessity coming even close for putting together life forms. That is the reason why Orgel and Shapiro came to mutual ruin some years ago.
What does this have to do with P(T|H)?
The only reasonable, empirically wrranted answer for the FSCO/I in the living cell, the root of the tree of life, is design. Only design — on trillions of examples — is empirically warranted as a causal source of FSCO/I. And if you want to play at the game of dismissing that reality, I again point to a world around us full of functionally organised complex entities where the functionality arises from interaction per a Wicken wiring diagram. The 6500 C3 reel, is a case in point, and using the nodes-arcs form of the wiring diagram to generate 3-d meshes, the gear train is a further subset that by itself is another case.
Many, many, many people disagree with you.
If you want to push the talking point that oh life forms reproduce, chemicals don’t. ANd that is where you must start.
Can we not change the subject? Let's make sure we're clear about P(T|H) first.
Indeed, as part of the ongoing, two years standing unanswered darwin essay challenge, you need to address the origin of a code and algorithm using von Neumann kinematic self replicator joined to gated, encapsulated, metabolising automata, as an integral part of the claimed blind chance and mechanical necessity origin of life assertions.
And that means I can't ask you about P(T|H)?
Where, I beg to remind you that Paley in 1804, in Ch II of his Nat Theol, moved on to the time keeping self reicating watch, and highlighted that the origin of that system is itself a major challenge and is credibly a further instance of artifice and design. This part of his argument of course has been generally not brought up in debates and assertions by darwinists over the past 150 years. But it is material, tot he point that the omission looks suspiciously like a strawman tactic.
I'm not interested in debating Paley's argument actually.
So, right from the root, FSCO/I points to the viability of design as a vera causa plausible explanation of life and the tree of life insofar as a tree is a valid representation.
So, when can we get back to P(T|H)?
When we move on to chance variation plus culling by differential reproductive success leading to descent with modification held to incrementally account for the tree of life above the root, that too runs straight into major challenges.
A worthy discussion but some other time please.
Notice, something vital: the vaunted natural selection is not a creative source of information, but instead it describes the after the fact loss of information by culling out varieties that go extinct as they are sufficiently less viable in niches to die off.
Mutations give and mutations take away.
This means that the source of creative information is chance variations. This is held to incrementally, slowly, climb a tree pattern across a continent of viable forms, to get to the branching tree of life.
Sounds pretty good to me.
While that is commonly taken for granted, it is in fact poorly founded. FSCO/I naturally leads to islands of function; as the simple exercise of putting 6500 c3 reel parts in a bag and shaking to explore the space of clumped configs. Predictably it will fail to find the ones that make a viable reel. Too deeply isolated for the search resources to credibly chance upon it by a 4andom walk or a scattered dust or a combination.
But, descent with modification does NOT lead to islands of function. We've had this discussion before.
So, it is utterly unsurprising to see how systematically, after 250k+ fossil species and millions of specimens in museums with billions in the field, we have not got the many, many, many missing links that mark the key branching points in the tree. A few circumpolar species and the like are not enough, starting from the Cambrian revolution and origin of major body plans onwards.
Good thing we've got other lines of evidence then eh?
Where, at foundation, after trillions of observed cases of origin of FSCO/I and many attempts, there is no current observational evidence that reasonably points to blind chance and mechanical necessity being an actual cause of FSCO/I.
I disagree. Anyway, that's enough of my responding to your off-topic lecture. We were specifically asking you about P(T|H). You chose to ignore those fundamental and fairly basic queries. So noted.Jerad

So, it is utterly unsurprising to see how systematically, after 250k+ fossil species and millions of specimens in museums with billions in the field, we have not got the many, many, many missing links that mark the key branching points in the tree. A few circumpolar species and the like are not enough, starting from the Cambrian revolution and origin of major body plans onwards. Where, at foundation, after trillions of observed cases of origin of FSCO/I and many attempts, there is no current observational evidence that reasonably points to blind chance and mechanical necessity being an actual cause of FSCO/I. (That, I suspect, is a big reason why so much effort was futilely invested in trying to dismiss the validity of he concept and/or to suggest that it cannot be quantified. Both have collapsed, and for years the facts have been on teh table, but were brushed aside. Now, we have it right there from 1973 and 1979, not form those despised de3sign thinkers, but from Orgel and Wicken. In the case of Orgel, he specifically used the common method of state identification and measuring the y/n chain of q's to specify state. Much as Shannon did in his well known 1948 paper.) Blind chance and mechanical necessity cannot be shown to be an observed cause of FSCO/I. It fails the vera causa test. So, the attempt to insist that the tree of life is a proof of such blind chance and mechanical necessity producing life and its forms from microbes to man, has failed to ground its causal force claims on actual observations adequate to explain a critical feature of life forms, FSCO/I. Which precise feature is a routine product of design. All the huffing and puffing about injecting supernatural into science, and on despising theism and denigrating theists collapses. The root issue is that we have an imposition of a priori materialism on science, and it cannot pass the empirical observation, vera causa test. Question-begging, in the teeth of where inductive logic points. FSCO/I is a reliable sign of design, inductively and on analysis of the challenge of sparse needle in haystack search, given the scope of config spaces vs atomic and temporal resources. Issues that are routinely derided and brushed aside, but have not been adequately answered. Until blind chance and mechanical necessity can pass the vera causa test of being observed to cause FSCO/I, it is not a reasonable candidate to explain FSCO/I as observed in traces from the past of origins of life and of body plans.

Clueless until the end, eh. Your position is the chance hypothesis, duh. And as such needs to provide H or admit that it has nothing. Oops we already know that.
I tell you what, just to be sure we're understanding each other, why don't you explain what the expression P(T|H) (as written by Dr Dembski) means. You've taken some math classes and have a high IQ so it should be easy. After that we can work on 'providing' H.Jerad

LoL! @ keith:
For literally years I’ve been pointing out that he can’t calculate P(T|H) correctly, because like Dembski and everyone else, he doesn’t have the required knowledge.
keith admits that unguided evolution is based on our ignorance. Nice own goal, again.Joe

I rather suspect he doesn't really understand what P(T|H) means. I also suspect that the reason that Dr Dembski no longer pushes his notion is that he realised it was a dead end. I know that KF starts off citing Dr Dembski's original expression but generally, on this forum, he uses a modified version where P(T|H) does not appear. The blog post you linked to is one of his endless regurgitations of his reasoning for doing so. He's got the same thing up on a website somewhere and he usually just copies and pastes it. I have read through it many times. His ability to lay out a mathematical case is sadly lacking clarity.Jerad

keith s - #153 I completely agree that one coin coming up heads 500 times is a row is highly suspicious. Clearly that deserves inspection. As I've said many times: if it happened to me I'd check things out. As you say flipping one coin 500 times is really 500 trials. I think my statement: try it again is better applied to a situation where 500 coins are flipped. That could be thought of as one trial. Sort of. Regardless, I completely agree that scrutiny is required. I am not saying, in either case, that I wouldn't be suspicious and highly skeptical. I would examine all aspects of the case as thoroughly as possible. I would not refer to that skepticism as inferring design however as that phrase has connotations which are best avoided (and unnecessary). We're not really disagreeing. We're just saying things a bit differently. And I'm trying to show the lack of rigour in KF's attempts at his kind of design inference. Material flaws or plain, old fraud are much more likely to be explanations than some undetected, undefined, non-material intelligent designer. It is interesting to think of the scenario of flipping a couple million fair coins and throwing out the ones that come up tails. Repeat. At the end you will get a fair coin that came up heads quite a few times in a row. No sleight of hand. No cheating. Nothing fishy at all. Just probabilities. Nothing to investigate. No design to infer.Jerad

Jerad,
P(T|H) is not part of any supposition of mine. It was part of a paper written by Dr Dembski. KF has eliminated that term in his restatement of Dr Dembski’s conjecture. It’s not up to us to explain why he did that or to help by ‘providing’ H. Why doesn’t KF just work with P(T|H)?
KF does use P(T|H) in his "chi_500" expression. See here, for example. For literally years I've been pointing out that he can't calculate P(T|H) correctly, because like Dembski and everyone else, he doesn't have the required knowledge.keith s
