Okay, the thread of discussion needs to pick up from here on.

To motivate discussion, let me clip here comment no 795 in the continuation thread, which I have marked up:

KF (783):

At this point, with all due respect, you look like someone making stuff up to fit your predetermined conclusion.

I know you think so.

[a –> Jerad, I will pause to mark up. I would further with all due respect suggest that I have some warrant for my remark, especially given how glaringly you mishandled the design inference framework in your remark I responded to earlier.]

{Let me add a diagram of the per aspect explanatory filter, using the more elaborated form this time}

The ID Inference Explanatory Filter. Note in particular the sequence of decision nodes

 

You have for sure seen the per apsect design filter and know that the first default explanaiton is that something is caused by law of necessity, for good reason; that is the bulk of the cosmos. You know similarly that highly contingent outcomes have two empirically warrantged causal sources: chance and choice.

You kinow full well that he reason chance is teh default is to give the plain benefit of the doubnt to chance, even at the expense of false negatives.

I suppose. Again, I don’t think of it like that. I take each case and consider it’s context before I think the most likely explanation to be.

[b –> You have already had adequate summary on how scientific investigations evaluate items we cannot directly observe based on traces and causal patterns and signs we can directly establish as reliable, and comparison. This is the exact procedure used in design inference, a pattern that famously traces to Newton’s uniformity principle of reasoning in science.]

I think SETI signals are a good example of really having no idea what’s being looked at.

[c –> There are no, zip, zilch, nada, SETI signals of consequence. And certainly no coded messages. But it is beyond dispute that if such a signal were received, it would be taken very seriously indeed. In the case of dFSCI, we are examining patterns relevant to coded signals. And, we have a highly relevant case in point in the living cell, which points to the origin of life. Which of course is an area that has been highlighted as pivotal on the whole issue of origins, but which is one where you have determined not to tread any more than you have to.]

I suppose, in that case, they do go through something like you’re steps . . . first thing: seeing if the new signals is similar to known and explained stuff.

[d –> If you take off materialist blinkers for the moment and look at what the design filter does, you will see that it is saying, what is it that we are doing in an empirically based, scientific explanation, and how does this relate to the empirical fact that design exists and affects the world leaving evident traces? We see that the first thing that is looked for is natural regularities, tracing to laws of mechanical necessity. Second — and my home discipline pioneered in this in C19 — we look at stochastically distributed patterns of behaviour that credibly trace to chance processes. Then it asks, what happens if we look for distinguishing characteristics of the other cause of high contingency, design? And in so doing, we see that there are indeed empirically reliable signs of design, which have considerable relevance to how we look at among other things, origins. But more broadly, it grounds the intuition that there are markers of design as opposed to chance.]

And you know the stringency of the criterion of specificity (especially functional) JOINED TO complexity beyond 500 or 1,000 bits worth, as a pivot to show cases where the only reasonable, empirically warranted explanation is design.

I still think you’re calling design too early.

[e –> Give a false positive, or show warrant for the dismissal. Remember, just on the solar system scope, we are talking about a result that identifies that by using the entire resources of the solar system for its typically estimated lifespan to date, we could only sample something like 1 straw to a cubical haystack 1,000 light years across. If you think that he sampling theory result that a small but significant random sample will typically capture the bulk of a distribution is unsound, kindly show us why, and how that affects sampling theory in light of the issue of fluctuations. Failing that, I have every epistemic right to suggest that what we are seeing instead is your a priori commitment to not infer design peeking through.]

And, to be honest, the only things I’ve seen the design community call design on is DNA and, in a very different way, the cosmos.

[f –> Not so. What happens is that design is most contentious on these, but in fact the design inference is used all the time in all sorts of fields, often on an intuitive or semi intuitive basis. As just one example, consider how fires are explained as arson vs accident. Similarly, how a particular effect in our bodies is explained as a signature of drug intervention vs chance behaviour or natural mechanism. And of course there is the whole world of hypothesis testing by examining whether we are in the bulk or the far skirt and whether it is reasonable to expect such on the particularities of the situation.]

The real problem, with all respect, as already highlighted is obviously that this filter will point out cell based life as designed. Which — even though you do not have an empirically well warranted causal explanation for otherwise, you do not wish to accept.

I don’t think you’ve made the case yet.

[f –> On the evidence it is plain that there is a controlling a priori commitment at work, so the case will never be perceived as made, as there will always be a selectively hyperskeptical objection that demands an increment of warrant that is calculated or by unreflective assertion, unreasonable to demand, by comparison with essentially similar situations. Notice, how ever so many swallow a timeline model of the past without batting an eye, but strain at a design inference that is much more empirically reliable on the causal patterns and signs that we have. That’s a case of straining at a gnat while swallowing a camel.]

I don’t think the design inference has been rigorously established as an objective measure.

[g –> Dismissive assertion, in a context where “rigorous’ is often a signature of selective hyperskepticism at work, cf, the above. The inference on algorithmic digital code that has been the subject of Nobel Prize awards should be plain enough.]

I think you’ve decided that only intelligence can create stuff like DNA.

[h –> Rubbish, and I do not appreciate your putting words in my mouth or thoughts in my head that do not belong there, to justify a turnabout assertion. You know or full well should know, that — as is true for any significant science — a single well documented case of FSCO/I reliably coming about by blind chance and/or mechanical necessity would suffice to break the empirical reliability of the inference that eh only observed — billions of cases — cause of FSCO/I is design. That you are objecting on projecting question-begging (that is exactly what your assertion means) instead of putting forth clear counter-examples, is strong evidence in itself that the observation is quite correct. That observation is backed by the needle in the haystack analysis that shows why beyond a certain level of complexity joined to the sort of specificity that makes relevant cases come from narrow zones T in large config spaces W, it is utterly unlikely to observe cases E from T based on blind chance and mechanical necessity.]

I haven’t seen any objective way to determine that except to say: it’s over so many bits long so it’s designed.

[i –> Strawman caricature. You know better, a lot better. You full well know that we are looking at complexity AND specificity that confines us to narrow zones T in wide spaces of possibilities W such that the atomic resources of our solar system or the observed cosmos will be swamped by the amount of haystack to be searched. Where you have been given the reasoning on sampling theory as to why we would only expect blind samples comparable to 1 straw to a hay bale 1,000 light years across (as thick as our galaxy) will reliably only pick up the bulk, even if the haystack were superposed on our galaxy near earth. Indeed, just above you had opportunity to see a concrete example of a text string in English and how easily it passes the specificity-complexity criterion.]

And I just don’t think that’s good enough.

[j –> Knocking over a strawman. Kindly, deal with the real issue that has been put to you over and over, in more than adequate details.]

But that inference is based on what we do know, the reliable cause of FSCO/I and the related needle in the haystack analysis. (As was just shown for a concrete case.)

But you don’t know that there was an intelligence around when one needed to be around which means you’re assuming a cause.

[k –> Really! You have repeatedly been advised that we are addressing inference on empirically reliable sign per patterns we investigate in the present. Surely, that we see that reliably, where there is a sign, we have confirmed the presence of the associated cause, is an empirical base of fact that shows something that is at least a good candidate for being a uniform pattern. We back it up with an analysis that shows on well accepted and uncontroversial statistical principles, why this is so. Then we look at cases where we see traces from the past that are comparable to the signs we just confirmed to be reliable indices. Such signs, to any reasonable person not ideologically committed to a contrary position, will count as evidence of similar causes acting in the past. But more tellingly, we can point to other cases such as the reconstructed timeline of the earth’s past where on much weaker correlations between effects and putative causes, those who object to the design inference make highly confident conclusions about the past and in so doing, even go so far as to present them as though they were indisputable facts. The inconsistency is glaringly obvious, save to the true believers in the evo mat scheme.]

And you’re not addressing all the evidence which points to universal common descent with modification.

[l –> I have started form the evidence at the root of the tree of life and find that there is no credible reason to infer that chemistry and physics in some still warm pond or the like will assemble at once or incre4mentally, a gated, encapsulated, metabolising entity using a von Neumann, code based self replicator, based on highly endothermic and information rich macromolecules. So, I see there is no root to the alleged tree of life, on Darwinist premises. I look at the dFSCI in the living cell, a trace form the past, note that it is a case of FSCO/I and on the pattern of causal investigations and inductions already outlined I see I have excellent reason to conclude that the living cell is a work of skilled ART, not blind chance and mechanical necessity. thereafter, ay evidence of common descent or the like is to be viewed in that pivotal light. And I find that common design rather than descent is superior, given the systematic pattern of — too often papered over — islands of molecular function (try protein fold domains) ranging up to suddenness, stasis and the scope of fresh FSCO/I involved in novel body plans and reflected in the 1/4 million plus fossil species, plus mosaic animals etc that point to libraries of reusable parts, and more, give me high confidence that I am seeing a pattern of common design rather than common descent. This is reinforced when I see that ideological a prioris are heavily involved in forcing the Darwinist blind watchmaker thesis model of the past.]

We’re going around in circles here.

[m –> On the contrary, what is coming out loud and clear is the ideological a priori that drives circularity in the evolutionary materialist reconstruction of the deep past of origins. KF]>>

GP at 796, and following,  is also a good pick-up point:

__________

>>796

  1. Joe:

    If a string for which we have correctly assesses dFSCI is proved to have historically emerged without any design intervention, that would be a false positive. dFSCI has been correctly assessed, but it does not correspond empirically to a design origin.

    It is important to remind that no such example is empirically known. That’s why we say that dFSCI has 100% specificity as an indicator of design.

    If a few examples of that kind were found, the specificity of the tool would be lower. We could still keep some use for it, but I admit that its relevance for a design inference in such a fundamental issue like the interpretation of biological information woudl be heavily compromised.

  2. If you received an electromagnetic burst from space that occurred at precisely equal intervals and kept to sidereal time would that be a candidate for SCI?

  3. Are homing beacons SCI?

  4. Jerad:

    As you should know, the first default is look for mechanical necessity. The neutron star model of pulsars suffices to explain what we see.

    Homing beacons come in networks — I here look at DECCA, LORAN and the like up to today’s GPS, and are highly complex nodes. They are parts of communication networks with highly complex and functionally specific communication systems. Where encoders, modulators, transmitters, receivers, demodulators and decoders have to be precisely and exactly matched.

    Just take an antenna tower if you don’t want to look at anything more complex.

I am fairly sure that this discussion, now in excess of 1,500 comments, lets us all see what is really going on in the debate over the design inference. END

Petrushka: I keep forgetting. What is the procedure for correctly calculating or assessing dFSCI? What test or procedure rules out the possibility tha a protein domain started as a “random” string with a weak function and became optimized in just a handful of steps? No problem, I keep reminding it to you. It's not me who have to rule out an imaginary mechanism. It's you who have to show a real mechanism. Show the random string, demobstrate that it is common enough in a random library, and give us the naturally selectable intermediates, each giving a reproductive advantage in some living system.gpuccio

Yes, how many times have we all asked them to define ID without resorting to a negative position on evolution.
Yet another great example of the sorts of things we have to deal with. ID claims to offer a better explanation for some features of living things. A better explanation than what? I'll give you one guess. So of course ID has to H into account. But P(H) is non-negative. Even keiths knows that! We give Darwinian evolution credit for what it can do. It just doesn't appear that it's able to do all that much. Now, just to see if you can get back on topic, in what way has gpuccio defined dFSCI in such a way as to resort to a negative position on evolution?Mung

Joe (33):
You just don’t get it. If your position could substantiate its claims then we wouldn’t be having this discussion as Newton’s Four Rules of Scientific Investigation say we do not add entities unnecessarily.
We can quit having this discussion any time. I'm happy to admit I'm right whenever you are.
Also we do not know that humans designed Stonehenge. We may infer it because allegedly they were around when it was built, but that doesn’t mean they did it. And if it wasn’t for Stonehenge’s existence we wouldn’t think that the people of that island could construct such a thing.
Are you serious? Really? Joe, you really, really need to read up on archaeology and stone circles. Seriously. Before you embarrass yourself.
No one has found any plans, nor documentation nor lab experiment.
Pertaining to independent evidence ofr a designer- the evidence for a designer from biology is independent from the evidence for a designer from cosmology with is independent from the evidence for a designer in astronomy which is independent from the evidence for a designer from physics, etc (chemistry, geology)
But they all suffer from the same common fallacy: inferring a cause with has not been proven to been in existence at the time. Joe! Guess what? I think alien astronauts designed the statues on Easter Island. I haven't got any evidence of aliens being around at the time except for these big statues which i can't explain. And I can't say for sure that the local humans weren't able to do it but I don't personally know how they did. What do you think? If we can't explain it within so many years then can we say it's ancient aliens?Jerad

Toronto: I am ot sure I understand your points, that seem to derive from discussions you had with others, and that I had not the time to follow. Your question: "Is “dFSCI” a characteristic of “information” or is it a characteristic of its source?" has no meaning for me, and no correspondence im ,y terminology. For me, dFSCI is a property od the object. Empirically, it is found only in designed objects. If you want to call that "a source", be my guest, but I can't see why. Least of all I can understand what you mean with being "independent of the source". Coud you explain, please? Finally, I would say that dFSCI is a metric only of itself. It is a categorized assessment of the information necessary to express a function. kairosfocus and Upright BiPed both claim “all possible strings of length x”. It would be interesting to see if gpuccio agrees with that. Yes, I agree, but it is an approximation. In principle, shorter or longer strings can express the function. But we assume that length x represents well enough the target space/search space ratio. To evaluate all possible strings, of any length, that can express the funtion as a target space, and all possible strings of any length as search space would be rather intractable. Only “a” depends on the string. No. The function, the target space and the search space all depend on the string. The threshold essentially depends on the probabilistic resources of the system (the time span by te number of states that can be tested for unit of time). Again, I don't understand what you mean with "the source". So if two strings, both of them complex, specific and functional enough to qualify as “dFSCI” before their origins are specified, with the only difference being one’s source was a “designer” and the second was a result of a “necessity mechanism”, they would both qualify as having “dFSCI”, even though only one was the result of an “intelligent designer”. They would both be assessed as having dFSCI. The first would be a true positive. The second (that has never happened) would be a false negative. dFSCI is assessed form the object (and the system). If the two objects are the same, and they appear in the same system, the assessment of dFSCI must necessarily be the same for both. If independent facts can attest a different origin for the two objects, thatwould imply what I have said: one is a true positive, the other a false positive.gpuccio

Joe (30):
And for DNA functional redundancy? And for transposons? And for redundant pseudogenes? And for ERVs? All those things are consistent with universal common descent. And that’s only part of the genetic evidence.
How do you know that is evidence for universal common descent? What part of UCD mandates protein functional redundancy?
I'm not about to spend post after post teaching you basic genetics. If you really want to know go do some reading.
What about the bio-geographic evidence? Why are lemurs naturally endemic to one island? I know you think lots and lots of life was pre-coded so . . . where is that coding and how does it limit lemurs to one island?
Your position can’t explain lemurs. So perhaps you should stop with your “Gish Gallop” and focus on that.
Absolutely my position can explain lemurs. A population of primates migrated to Madagascar and evolved in isolation from the mainland from which they were separated. Easy.
And if you don’t have any idea on the number of mutations it takes, then you don’t have science.
Do you know how many mutations it takes?
The point is there isn’t any evidence that any amount of mutational accumulation can account for the transformations required.
Hang on. You raised a challenge, I turned it back on you, and you punted. You don't have an answer either Joe. Best to just admit it really.
What about my other, simple question: if a signal from space was detected that was on a constant frequency at a constant interval from a single location would it be a candidate for being SCI?
If it was a nice sine wave, it would be a good candidate.
Thank you for that clear and direct answer. It conflicts with KF's but reasonable people disagree at times.Jerad

Mark: In what sense was the protein correctly assessed? You thought there was no necessity mechanism and it turns out there was! How can this be a correct assessment? Please, read again my post #20. And read all! "I will be more clear. But I must say, before going on, what I consider a correct assesment of dFSCI: a) The function must be defined explicitly, and must be objectively measurable. b) The threshold must be appropriate for the sytstem being considered, and for its probabilistic resources. c) The target space/search space ratio must be approximated as well as possible, and must be credible. d) All strings that exhibit high regularity and compressibility should not be considered as exhibiting dFSCI, just to be cautious. Those output can be very likely explained by necessity mechanisms. e) For all strings whose formal appearance is of the “pseudo-random” type, with no apparent order or regularity, we can usually infer dFSCI with safety, if all other conditions are present. However, a thorough consideration of the laws that act in the system must be done, and we must be reasonably sure that those laws have no special connection with the specific string we are considering. If all these conditions are well satisfied, I consider the assessment of DFSCO as correct. As you can see, there is a lot of work to be done to assess a property that you label as “redundant” and “unnecessary”. Now, I do believe that if all those properties are satisfied, no future explanation will ever be found for that dFSCI, except obviously design. That is not a defintion, nor an inference, nor a fact, just to be clear. Let’s call it “a prediction”. Empirical experience will confirm that prediction, or will falsify it. It is not so strange, after all. Even Mark has admitted that he does not really believe that any future necessity mechanism will ever be found to explain that sonnet. Let’s say that I am as sure that no mechanism will ever explain protein domains, as Mark is that no mechanism will ever explain the sonnet. So, let’s say that if such a mechanism is credibly shown, I will consider my theory falsified." This is the sense in which the protein is correctly assessed: we must follow the procedures as I have outlines them. We are confident that, if those procedures are sollowed, no necessity mechanism will be discovered in the future that can explain the string that was assessed as exhibiting dFSCI. Obviously, if that should happen, it is a falsification of the concept or the procedure (or both). What's your problem?gpuccio

Keiths: Are you completely mad? What you say has no meaning.
You only infer design when RV and ‘necessity mechanisms’ have been ruled out. That will create some false negatives, but it’s better to have false negatives than false positives, as you have pointed out. So every functional sequence falls into one of three categories: 1) simple enough to have been produced by RV (and, of course, design) 2) too complex for RV, but could have been produced by ‘necessity mechanisms’ (and, of course, design) 3) out of reach for RV and ‘necessity mechanisms’, so could only be produced by design
But what are you saying here? This is nonsense! A thing is designed if, and only if, a conscious intelligent agent outputted his representation to the object to purposefully shape it! This is the definition of design. A thing is not considered designed if it is "out of reach for RV and ‘necessity mechanisms’, so could only be produced by design". What stupid definition is this? A thing is designed if someone designs it. It is not designed if nobody has designed it. Period. Being designed has nothing to do with RV, necessity or anything else. Design is only inferred if the tests for #1 and #2 are not satisfied, meaning we “fall through” to the default, which is #3 — design. Absolutely not! Again, you must be mad. After all, you could not be a liar, and I eill have to apologize. In the tests, the origin (design or not design) is not inferred: it is known before the tests, becaise the history of the strings is known. So again, are you simply mad?
Now look at your criteria for establishing the presence of dFSCI: a) High functional information in the string (excludes RV as an explanation) b) No known necessity mechanism that can explain the string (excludes necessity explanation) So dFSCI is attributed to a sequence if it can’t be explained by RV or necessity mechanisms.
That's correct. But it must also be functional, let's remind that too.
But we saw earlier that design is attributed to a sequence if it can’t be explained by RV or necessity mechanisms.
No. Absolutely not. You said those silly things, because apparently you have understood absolutely nothing of the discussion, and still go on patronizing everyone! I don't know if you are mad, but you are certainly very arrogant. It's only you, in your confused mind, that attribute design in the same way that I attribute dFSCI. Of course you conclude that it is circular! This is a farce. The origin of a string is a fact, that can be observed. In the testing phase, we only use strings whose origin has been observed to test the specificity of dFSCI (obviously, in blind). It's only in the application of dFSCI to strings whose origin is not known that we make an inference: from the property of dFSCI (observed in the object) to an inference of a design origin (inference of a fact). No circularity. And if you really don't understand it now, what should I think of you? Please, answer to this and only to this, next time.gpuccio

In which case there could have been multiple meteors and multiple aliens with lunchboxes, and life could have been seeded on earth at independent times and places, and evolutionary theory is perfectly consistent with that. Yes. We know that. Now think about what that means for your argument.
It could have happened that way. The important thing is that a basic replicator got a foothold on earth. It doesn't really change anything to be honest. What have you got in contrast? Aside from bitching and moaning?Jerad

Mung: So evolutionary theory includes a theory about how body plans develop? Do tell. Jerad: Yes it does. What is it? Do tell. Jerad:
Why are you asking me really basic questions about evolutionary theory when I thought you were well versed in the topic?
Because I don't believe you. All this talk from kf asking about where body plans come from and this is the first time I can recall seeing you say evolutionary theory explains where body plans come from. That and that new body plans aren't all that hard to come by because they are all very close together in the configuration space. I'm just really curious about where you're getting this information from and why you haven't brought it up before.
Living systems don’t do random searches across whole configuration spaces to find new body plans.
So how much of the space do they need to search in order to find a new body plan and how do you know?Mung

Well, duh! Living systems already have a body plan. So they don’t need to go off looking for one. Are you saying you believe in special creation? If not, where did those body plans come from?

Joe: The elimination of obvious necessity mechanisms is necessary to eliminate compressible strings, or any other ordered output that can be explained by necessity. It is the first step in KF's algorithm, it is an essential part of Dembski's explanatory filter. My idea is that what can be explained by necessity is not complex. That's why I put point 3 in the definition. KF puts it at the beginning. There is no difference. This has nothing to do with the philosophical question that darwinists pose: but if one day a necessity mechanism were found... For pseudo-random strings, that mechanism will never be found, because necessity cannot generate that kind of strings. And, as I have explained, if it were found it would falsify the whole dFSCI procedure. The complexity in pseudo random strings is tied to the fact that they cannot be generated by any simple computation, and therefore a high number of bits is required to express the function. I insist that a string of 500 heads does not exhibit dFSCI: it is highly compressible, and it can easily be generated in a natural system. In the same way, a gene made of 300 identical nucleotides does not exhibit dFSCI: it can be easily generated in the lab, from a pool with only one nucleotide available. So, necessity mechanisms must be excluded in the definition, because otherwise we are not sure of the complexity, and we cannot make the inference.gpuccio

Yes it does. Why are you asking me really basic questions about evolutionary theory when I thought you were well versed in the topic? You tell me: is there a configuration space? Is there a random walk? And why haven't you answered my simple question: if we detect a periodic signal from space at a constant frequency and location is it a candidate for SCI?Jerad

Sure, if you know there’s deer around at the time.
Here you are once again being intellectually dishonest. If you can't be trusted to be honest there's not much point in debating you. You wrote:
I’m happy to draw inferences to causes known to be operating at the given time or reasonably likely to have been operating at the given time.
You flip flop back and forth in order to immunize yourself against reason. Given deer tracks, it's reasonably likely there was s deer around at the time. Given your own words, this should be enough for you. But when it comes to ID, you want to change the rules.
Do you know there was a designer around when you’re inferring one?
Who said anything about inferring a designer? Here's what I wrote:
So yes, you can infer the cause if you observe the effect.
Do you disagree that a cause can be inferred by it's effects? Have you ever seen gravity? How do you even know it exists?
But you don’t know if there was a designer around at the pertinent time.
So? I don't need to know a designer was around. I look up in the sky and see a contrail. Do I need to know a jet was around at the time before I can make an inference as to what caused the contrail? Do I need to go find independent proof that a jet was around? The answer is no, I don't. You know it, I know it, and everyone reading this thread knows it. Your requirements are bogus.
Prove the cause exists AND is present at the given time if you want to compete with theories which don’t require special pleading.
There's no alternative theory that I'm aware of. Do you have one that you're willing to put forward and defend? We all already know the answer to that question. So, again, intellectual dishonesty. And as I said, even if there is a competing theory that doesn't invalidate the inference we've made. Do you have a counter-argument?
You’re assuming there was a designer around with no independent evidence for one.
That's simply false. I'm making no such assumption. So I don't need independent evidence for some assumption I'm not making.
Show me some physical evidence that a designer was present. Some artefacts. Some living quarters. Some lab equipment. Some documentation.
Those things are not causes. So how on earth would they provide independent proof? I've got no physical evidence that you exist. You've produced no artifacts. I've never seen your living quarters. I've never seen your computer or any documentation proving you exist or even have an internet account. Like I said earlier, you are being completely unreasonable.Mung

Jerad, You just don't get it. If your position could substantiate its claims then we wouldn't be having this discussion as Newton's Four Rules of Scientific Investigation say we do not add entities unnecessarily. Also we do not know that humans designed Stonehenge. We may infer it because allegedly they were around when it was built, but that doesn't mean they did it. And if it wasn't for Stonehenge's existence we wouldn't think that the people of that island could construct such a thing. No one has found any plans, nor documentation nor lab experiment. Pertaining to independent evidence ofr a designer- the evidence for a designer from biology is independent from the evidence for a designer from cosmology with is independent from the evidence for a designer in astronomy which is independent from the evidence for a designer from physics, etc (chemistry, geology)Joe

You can’t infer to something if you’re not sure it was there…
Yes, you can. If you observe the effects, you can infer something was there. e.g., deer tracks.
Sure, if you know there's deer around at the time. Do you know there was a designer around when you're inferring one?
You can’t infer to something if you’re not sure it was there…
We’re not inferring some thing. We’re inferring a cause known to be capable of producing the effect. So yes, you can infer the cause if you observe the effect. That’s how science works.
But you don't know if there was a designer around at the pertinent time.
You can’t infer to something if you’re not sure it was there when there’s other theories which explain the phenomena which do not require that assumption.
What assumption? No one is making any assumption here.
You're assuming there was a designer around with no independent evidence for one.
You can’t infer to something if you’re not sure it was there when there’s other theories which explain the phenomena which do not require that assumption.
So if there’s no competing theory which explain the phenomena, you can in fact infer to something, even if you’re not sure it was there? And what’s the competing theory for the system KF described, the system that must have been in place for your common descent theory to even be tenable? And if there is none, we’re warranted in inferring design for OOL?
If there's no competing theory then you can try but it's still just a hypothesis and one that needs more evidence. The competing theory is the modern evolutionary synthesis.
You can’t infer to something if you’re not sure it was there when there’s other theories which explain the phenomena which do not require that assumption.
Yes, you can. Then you’d just have two competing theories. But I can’t imagine what that other theory would look like if it too wasn’t operating on inference from effect to cause. Can you give an example?
Of course you'd be operating on effect to cause but to a cause known to be present at the time!!
I’m happy to draw inferences to causes known to be operating at the given time or reasonably likely to have been operating at the given time. As you say, that’s a common method of reasoning in many fields.
If the effect is there, then the cause is known to have been operating at the given time or reasonably likely to have been operating at the given time.
Nope. Erich von Daniken hypothesised ancient astronauts. Wrong. N-rays. Wrong. Ether. Wrong. Prove the cause exists AND is present at the given time if you want to compete with theories which don't require special pleading.
But only in ID are people inferring to a cause that has no independent proof of being in existence at the time in question.
Independent proof? That’s your standard? So in addition to being able to infer the cause from the effect you need independent proof? Proof of what? How do you propose that we separate the cause from the effect such that we can establish independent proof of the cause? You are being completely unreasonable. Once again, your intellectual dishonesty is showing through.
Show me some physical evidence that a designer was present. Some artefacts. Some living quarters. Some lab equipment. Some documentation. We separate the cause from the effect all the time. I'm not being unreasonable when you're asking me to accept an undefined and unobserved designer who did something at some undefined time at some undefined place for some undefined reason. Hey, Mung! I think there's an alien spacecraft that's shadowing the Voyager spacecraft which is exerting a small gravitational pull on it which explains why it's travelling slightly slower than we expect it to. Would you buy that explanation? We know that kind of gravitational effect would work. We know how to build spacecraft. It's a hypothesis. Hey, Mung! I've detected a regularly occurring radio signal from a constant point in space at a fixed frequency. I think it's an alien distress call, a homing beacon. It's the kind of homing beacon our ships and craft send out. We can conceive of doing that kind of thing. It's a hypothesis. Erich von Daniken convinced a lot of people that the lines at Nazca were created by alien astronauts. We have astronauts. We can make spaceships and flying craft. It's a hypothesis. I'm gonna need more evidence before I buy into those things.Jerad

So, what is in the definition? 1) A functional specification 2) High digital complexity linked to that specification 3) No known necessity mechanism that cam explain that complexity Is that OK?
I would think 3) should be in the inference. If we see 1) and 2) we infer design because of 3) and 4) If we observe 1) and 2) and it turns out that some necessity mechansim produced it, it does not stop having "a functional specification and High digital complexity linked to that specification"- a bacterial flagellum is still a specified functional thingy regardless of how it came to be that way. It doesn't stop exhibiting dFSCI if natural selection didit. However dFSCI does stop being a design indicator if that is ever demonstrated. It would either be dFSCI is no longer a design indicator of dFSCI doesn't exist. Because if you say that if a necessity mechanism produced it, it ain't dFSCI even though it meets the criteria, then you do have a circular definition.Joe

No genetic evidence?
Non that supports the transformations required are even possible. Do try to stay focused.
So what’s your explanation for protein functional redundancy?
What does that have to do with what I said about the transformations required?
And for DNA functional redundancy? And for transposons? And for redundant pseudogenes? And for ERVs? All those things are consistent with universal common descent. And that’s only part of the genetic evidence.
How do you know that is evidence for universal common descent? What part of UCD mandates protein functional redundancy?
What about the bio-geographic evidence? Why are lemurs naturally endemic to one island? I know you think lots and lots of life was pre-coded so . . . where is that coding and how does it limit lemurs to one island?
Your position can't explain lemurs. So perhaps you should stop with your "Gish Gallop" and focus on that. And if you don’t have any idea on the number of mutations it takes, then you don’t have science.
Do you know how many mutations it takes?
The point is there isn't any evidence that any amount of mutational accumulation can account for the transformations required.
What about my other, simple question: if a signal from space was detected that was on a constant frequency at a constant interval from a single location would it be a candidate for being SCI?
If it was a nice sine wave, it would be a good candidate.Joe

Like I’ve said: as far as evolutionary theory is concerned, that first basic replicator could have ridden in on a meteor. Or fallen out of a alien visitor’s lunch box.
In which case there could have been multiple meteors and multiple aliens with lunchboxes, and life could have been seeded on earth at independent times and places, and evolutionary theory is perfectly consistent with that. Yes. We know that. Now think about what that means for your argument.Mung

Wishful thinking is no a substitute for evidence and arguments. You'd certainly like them to be more likely. In fact you need them to be more likely. But what is your evidence that they are more likely? Please provide independent proof! You're wishing it was so does not make it so.Mung

Your argument is based on a random search of a whole configuration space. And that’s NOT how new body plans are developed according to evolutionary theory so the argument is not applicable for anything after the first basic replicator as an argument against universal common descent with modification.
So evolutionary theory includes a theory about how body plans develop? Do tell. (Not by intelligent design doesn't count as a theory.) Is there a configuration space? Is there a random walk?
Your argument is based on a random search of a whole configuration space.
It's not possible to search the whole space! So no, that's not his argument.
...and so there’s no need or cause to search the whole configuration space then either.
Given random mutations, what is constraining the search to only a small subset of the configuration space?
Living systems don’t do random searches across whole configuration spaces to find new body plans.
Well, duh! Living systems already have a body plan. So they don't need to go off looking for one. Are you saying you believe in special creation? If not, where did those body plans come from?Mung

Forgot, a signal that is regular would most plainly be attributed to unknown natural cause as the contingency is low. What would be attributed as designed by the EF is a complex aperiodic and plainly functional signal. Remember, false negatives would be cases of design not detected on grounds that there is not sufficient indication of design. Better to toss the little ones back. Back to crashes, incidents and reports, sigh.
Thank you for giving a direct and clear answer. I agree with you and I left out functional intentionally obviously. I hope things are starting to calm down. We're having a big upheaval here in England regarding a now deceased (rather famous) individual who apparently was a serial abuser and he was for decades without anyone getting his behaviour looked into.

How many times have I had to point out to you that if you opt for a blindly selected subspace, then you are looking at searching, not the original space blindly, of magnitude W, but its POWER SET, of magnitude 2^W. For the space of 1,000 bits, there are W = 1.07*10^301 possibilities. The search in the power set, gives you the need to explain searching a secondary space so big that its log to base 2 is 1.07*10^301, expressed in decimal digits.
Good thing I'm not opting for that then eh?
In short, you have substituted a much harder second order search. Compared to that, the original search is a conservative estimate.
Good thing I'm not making that substitution then.
The alternative is to already be in the target zone, which leaves the zone unexplained, or to have intelligent choice of the zone of search, which is what you do not want.
The first basic replicator wouldn't be the first basic replicator if it weren't already in a 'target zone', exactly. You don't have to do a search for a zone of search! Like I've said: as far as evolutionary theory is concerned, that first basic replicator could have ridden in on a meteor. Or fallen out of a alien visitor's lunch box. I think those options just push the problem back but they are possibilities. Whatever, first basic replicator that uses our genetic code appears. . . you're on a big island of function (if there is more than one) and life starts covering it with life forms. Simple. No 'islands of function'. Just universal common descent with modification. How did the first basic replicator arise? I don't know. I don't think you have to search a huge configuration space (or it's power space) to get there though. Some chemical bonds aren't gonna happen. Not all configurations are 'sampled'. Some bonds will build on themselves and each other. It's a problem, I agree. People are working on it. They haven't figured it out yet. But I disagree that it's time to throw in the towel and say it couldn't have happened via necessity. Or chance. We don't know yet. I am not dodging the issue, I am saying we don't know. We don't even know what that first basic replicator looked like. You envision it to be too complicated to have arisen via chance or necessity but how do you know that if you don't know what it was? The alternative to design is NOT random searches on huge configuration spaces. You can make that argument as long as you like but you're not attacking evolutionary theory. That's not what evolutionary theory is saying. As far as I know no one is making that argument for the very reasons you lay out.Jerad

Petrushka: All that is necessary to invalidate gpuccio’s claim regarding diabetes is one false positive. Same for dFSCI. Which is why I think he is reluctant to give a specific example. The state of research is shifting rapidly, and protein evolution is at the center of a lot of research. Well, I am not affirming that glycemia has exactly 100% specificity. I made that example just to ahow that there in no circularity in that kind of statement. They can be right or wrong, but they are not circular. I don't really believe that hyperglicemia has 100% specificity for diabetes, but at that thershold (300 mg/dl, if I remember well) it must be pretty near. This is another important point: the high specificity can in many cases easily be obtained by setting the diagnostic threshold, but that implies having more false megatives. That's exactly what we do in ID with CSI. That's what I was suggesting with my example of a 100 mg/dl threshold for diabetes. It seems rather odd that gpuccio would cite medical diagnosis as the prototype for diagnosing design. It has not been too long since medical conditions were considered caused by spirits or were punishment for sin. Diagnosis is a poster child for leaky bucket classification. Maybe because I am a medial doctor? However, I can probably share with you many criticisms about my category :) _____ GP you have more than earned the recommendation of all concerned at UD as a first rate practitioner. And BTW, judging by differences in Luke's diagnostic remarks [which distinguish natural and supernatural causes of similar complaints], it seems P is at least 2,000 years out of date attributing such diagnoses across the board to physicians.

Joe Felsenstein: Thank you for a post that makes sense (I don't think your previous one did). The definition of dFCSI is not circular. Something has dFCSI if it has enough functional information that this cannot have arisen by random processes like mutation, and if that functional information cannot be explained by deterministic processes (which include natural selection). So far nothing circular about that. I am happy that somebody can still use reason correctly.
Drawing from the presence of dFCSI a conclusion that a genotype is the result of Design is * redundant. We already concluded that it cannot be explained by nonintelligent natural processes, which leaves only Design, * unnecessary. For the same reason. * circular, because we used property X of a genotype to conclude that dFCSI was present in it, but then used the presence of dFCSI in that genotype to conclude that it has property X. (Property X is the our inability to explain the genotype’s presence by random or by nonintelligent deterministic means).
Well, the first points are frankly nonsense: a) We infer design exactly because we have concluded that dFSCI is present. The fact that something is unlikely as a random output and is not explained by a necessity mechanism does not logically imply that it is designed. Many designed things could in theory originate for RV, or from a necessity mechanism, if they are simple enough. And we don't know hoe a designer generates things with high functional complexity. Therefore, the connection between dFSCI and a design origin cannot be given fro granted on logical grounds: it must be based on empirical observation, the observation that DFSCI detects design with 100% specificity in all cases where the true historical origin can be ascertained. For the same reason dFSCI is not unnecessary at all. WE must distinguish between simple biological molecules, that can be explained by RV or bnevessity, and highly complex polymers that cannot. We cannot just look at them and decide, we need a metrics. Now, the "circular". You have alredy conceded that the definition is not circular. Thank you for that. So, what is in the definition? 1) A functional specification 2) High digital complexity linked to that specification 3) No known necessity mechanism that cam explain that complexity Is that OK? Now, what is in the inference? 4) The empirical observation that all strings for which we assess dFSCI as present have a designed origin. What in 4) is logically implied by the definition? Nothing. To have a design origin us a fact that is ascertained by empirical observation. It is not a property of the object. It is not an inference. It is not a deduction. It is an observable fact. We observe, by experience, a strong connection (with 100% specificity) between the property of exhibiting dFSCI (that is, point 1,2 and 3), and the fact of having origin in a design process. No circularity, as everybody can see. Now, please, if you go on using the word "circularity", please explain what is wrong in what I have said. As everyone can see, your statement: "but then used the presence of dFCSI in that genotype to conclude that it has property X." is completely wrong. We use property X to infer origin O. Why do you say something completely different, after I have cleraly specified this point a lot of times in the last few days? Is it a misunderstanding on your part? Simple mental confusion on your part? A simple lie on your part? I don't know any more. You tell. I see that gpuccio is quite angered by characterizations like the above and is calling some of the people who make them liars. Yes, I am. If we could come up with even one case in which there was a “known” case of dFCSI that resulted from natural selection, then this would be a Big Problem for the use of dFCSI to infer Design. That's true. But “known” to who? I would say that a simple GA case with enough genes will bring about dFCSI. (But gpuccio rejects GAs as examples, on what I think are insufficient grounds). Yes, I reject them. But that's not the point. I have inferred dFSCI explicitly for many protein domains (all those that, in Durston't paper, exhibit more than 150 bits of functionla information). I am taking my risks. If you can show a credible, detailed explanation for any of them, I will promptly admit that all my theory about the application of dFSCI to biological information has received a very hard, maybe mortal, blow. In any case, if someone does come up with a natural selection mechanism to explain the presence of a putative case of dFCSI, does that case then automatically become not a case of dFCSI? This is a good question, and it deserves a clear answer, also because I have seen a lot of discussion about that, most of it very confused. First of all, I must say that dFSCI is for me a property of the object, which cab be objectively assessed in the object. However, it is not just "observed" in the object, because it is a complex property that needs an assessment through an integrated judgement. If that judgment is given correctly, according to the definition, I would say that any successive falsification of that judgement is a falsification of the utility of dFSCI itself, IOWs, the demonstration of a false positive. I will be more clear. But I must say, before going on, what I consider a correct assesment of dFSCI: a) The function must be defined explicitly, and must be objectively measurable. b) The threshold must be appropriate for the sytstem being considered, and for its probabilistic resources. c) The target space/search space ratio must be approximated as well as possible, and must be credible. d) All strings that exhibit high regularity and compressibility should not be considered as exhibiting dFSCI, just to be cautious. Those output can be very likely explained by necessity mechanisms. e) For all strings whose formal appearance is of the "pseudo-random" type, with no apparent order or regularity, we can usually infer dFSCI with safety, if all other conditions are present. However, a thorough consideration of the laws that act in the system must be done, and we must be reasonably sure that those laws have no special connection with the specific string we are considering. If all these conditions are well satisfied, I consider the assessment of DFSCO as correct. As you can see, there is a lot of work to be done to assess a property that you label as "redundant" and "unnecessary". Now, I do believe that if all those properties are satisfied, no future explanation will ever be found for that dFSCI, except obviously design. That is not a defintion, nor an inference, nor a fact, just to be clear. Let's call it "a prediction". Empirical experience will confirm that prediction, or will falsify it. It is not so strange, after all. Even Mark has admitted that he does not really believe that any future necessity mechanism will ever be found to explain that sonnet. Let's say that I am as sure that no mechanism will ever explain protein domains, as Mark is that no mechanism will ever explain the sonnet. So, let's say that if such a mechanism is credibly shown, I will consider my theory falsified. You ask: but then, has the protein still dFSCI? The answer is, this time, really useless. The protein had dFSCI correctly assessed. With all the available knowledge, it exhibited dFSCI. If a non design explanation is found, this is and remains a false positive. I hope the answer is clear enough. That is what the explanation above, immediately after gpuccio’s question, was assuming. My guess is that the answer is “yes”. And if so, then the argument really is circular. Well, I have not answered "yes", but I would like to add that if I had, the argument would not have become "circualr", but certainly "weaker". dFSCI is a disgnostic procedure. We must assess its specificity by applying it as it is. Any future development that can come into existence can only affect our judgement on that evaluation. I must remind you that we assess the specificity of dFSCI by strings whose origin is known. When we apply it to strings whose origin is not know, we can only "assume" that it will show the same specificity. IOWs, we are making an inference, not a deduction. Ther is not absolute certainty in an inference. If future developments undermine the validity of our inference, we have to admit that our tool did not show, in the applied field, the same specificity we observed in the testing phase. Just wanted to give my own answer to gpuccio’s question. I am saddened that all that gpuccio could make of my previous comment was that “Joe Felsenstein, I must say with great regret, is beyond any sense.” That was referred to your previous post. With all respect, I will maintain that judgement. I am well aware of the limitations of my ability to explain things, but I have written textbooks, including the standard text on inference of phylogenies. Reviews of my writings usually call then “clear” even when I’d prefer to have them called “elegant” or “inspiring”. But “clear” is the adjective people use most often. I fancy my previous couple of comments to have been clear, and am sorry if gpuccio thinks that they are “beyond any sense”, or that I myself am “beyond any sense”. We can have different opinions. This last comment of yours was very clear. I’m also grateful for gpuccio’s conclusion in an earlier case that “At least you have avoided an explicit lie.” Gee, thanks. You're welcome!gpuccio

No, it doesn’t. There isn’t any genetic evidence that suports the alleged transformations. The fossil evidence shows fish->tetrapods-> fish-a-pods- out of sequence.
No genetic evidence? So what's your explanation for protein functional redundancy? And for DNA functional redundancy? And for transposons? And for redundant pseudogenes? And for ERVs? All those things are consistent with universal common descent. And that's only part of the genetic evidence. What about the bio-geographic evidence? Why are lemurs naturally endemic to one island? I know you think lots and lots of life was pre-coded so . . . where is that coding and how does it limit lemurs to one island?
And if you don’t have any idea on the number of mutations it takes, then you don’t have science.
Do you know how many mutations it takes? What about my other, simple question: if a signal from space was detected that was on a constant frequency at a constant interval from a single location would it be a candidate for being SCI?Jerad
