US Officially Blames Russia

And that point has already been addressed.

Read the thread please.

What point do you have in mind?

Far as I can tell, Caveman1917 still claims every appeal to authority is a fallacy and, indeed, that real men don't use informal reasoning, but do a full Bayesian update every time a snippet of information comes in.

I don't see how pointing out to him that the exigencies of life require us all to appeal to authority on a regular basis, or else remain ignorant of well-settled scientific, historical and even mathematical claims. I believe that, for instance, FLT has been proved, Thales existed, four of Jupiter's moons were discovered by Galileo and even that Trump won the electoral vote on no basis other than multiple reliable sources told me each of these.

Until Caveman1917 agrees that some appeals to authority are reasonable, I'm sure examples like the vaccination and the ones I wrote above will come up.
 
Nah, it depends on the interpretation of probabilities. In Bayesianism, probabilities are interpreted as degrees of belief, the so-called subjective interpretation. Probability can certainly well model reasoning with incomplete information.

That's an example of using the same term for two different things (or three, if you count both the objectivist and subjectivist Beyesian interpretations). But Caveman specifically said "probability theory" which applies to the study of random distributions.
 
The fact that she is a proponent of conspiracy theories makes me distrust her reported quotes of CIA officials. I'm surprised you don't think similarly.

If anyone's a proponent of conspiracy theories it would be the US government and intelligence agencies. For goodness' sake, the claim under consideration is a conspiracy theory.

I believe you'll find the strongest thing I've said is that, in this case, where all of the agencies agree

Does the FSB agree? What about the MSS?

and a bipartisan group of congressmen find the evidence compelling

They'd probably find the evidence for a 6000 year-old Earth compelling as well.

(and, as someone pointed out, an independent private firm came to the same conclusion)

Do you have evidence that this private firm is "independent"?

I don't consider that conclusion to be advocacy of blind faith.

Here's the difference between advocacy of blind faith and skepticism:

You've mentioned this private firm (CrowdStrike) which "comes to the same conclusion". At least with its report it makes verifiable claims, as opposed to the intelligence agencies themselves.

Advocating blind faith would stop there and simply use that as a basis for believing the claims. Skepticism would be skeptical of it and attempt to investigate the claims. How about we try that approach for once?

CrowdStrike said:
In June CrowdStrike identified and attributed a series of targeted intrusions at the Democratic National Committee (DNC), and other political organizations that utilized a well known implant commonly called X-Agent. X-Agent is a cross platform remote access toolkit, variants have been identified for various Windows operating systems, Apple’s iOS, and likely the MacOS. Also known as Sofacy, X-Agent has been tracked by the security community for almost a decade, CrowdStrike associates the use of X-Agent with an actor we call FANCY BEAR. This actor to date is the exclusive operator of the malware, and has continuously developed the platform for ongoing operations which CrowdStrike assesses is likely tied to Russian Military Intelligence (GRU). The source code to this malware has not been observed in the public domain and appears to have been developed uniquely by FANCY BEAR.

Here, have the source code of X-Agent. That wasn't particularly hard, now was it? So much for that "exclusive operator of the malware" then.

CrowdStrike said:
Today CrowdStrike is releasing publicly an intelligence report which was circulated to CrowdStrike Falcon Intelligence customers detailing the use of the trojanized ‘Попр-Д30.apk’ application by the Ukrainian military and the deadly repercussions inflicted on that platform by Russian forces.

Interestingly the Ukrainian government denies this purported Russian hacking of their artillery outright, and explicitly asks media not to spread false information like this.
 
That's an example of using the same term for two different things (or three, if you count both the objectivist and subjectivist Beyesian interpretations). But Caveman specifically said "probability theory" which applies to the study of random distributions.

In the literature (which I have not read in years), they speak of frequentist, subjectivist and (I think) objectivist interpretations of probabilities.

Anyway, probably not necessary to get too involved in mere terminology. I don't think this distinction makes much of a difference in the long run.
 
Each of these claims (she held an official position, the CIA had disinfo campaigns) is justified fundamentally by an appeal to authority on your part, unless you have direct evidence. As such, you are relying on an argument that you have explicitly called fallacious.

That is correct. Technically it is all fallacious. Personally, I go with accepting a claim by someone if that someone has a vested interest in denying the claim. For example if the Russian government says "yep we did the hacks" then I would accept that, even if it also technically an appeal to authority.
 
If anyone's a proponent of conspiracy theories it would [...]

I've told you that I'm not interested in convincing you that these agencies, CrowdStrike, and the congressional committees are trustworthy authorities.

I am, however, interested in knowing whether you admit that your citation of the Casey quote is (by your own addled understanding) a fallacy. Clearly, it was an appeal to authority and you (mistakenly) believe that all such appeals are fallacious.

So, do you agree that by your own claims, everything you've said about Casey and, indeed, any of past CIA activities you have not witnessed are the products of fallacious reasoning?

This is not a tu quoque attempt. I'm not saying that this would make your understanding of appeal to authority wrong[1]. I just want to be sure that you agree that your own statements on appeal to authority entail that we reject the above statements.

Similarly, it should be said, according to other statements of yours, you have not engaged in almost any "meaningful" reasoning in this thread. For instance, on the basis of past CIA activities, you infer that they are not trustworthy -- an example of informal inductive reasoning. You really should take the time to give your full probability distribution over the set of meaningful propositions, so that we can see the outcome of your Bayesian calculations.

[1] Though it is, of course, wrong.

Okay, so you intentionally engage in what you consider fallacious reasoning throughout this conversation. Evidently, you don't care about reaching a reasonable conclusion, so perhaps we should end our conversation.

Or perhaps I'll adopt a similar strategy, and use a Magic 8-Ball to compose my replies.
 
BS. You've been "asking for the evidence" knowing full well that you are not going to get classified information until it's declassified.

That's not my problem. No evidence is no evidence, irrespective of how you want to rationalize it.

The first time I asked you if your skepticism meant that you supported a full congressional investigation, you said "no" with no explanation.

I support the publication of the evidence. The furthest I'm willing to go is to have the evidence given for independent review to randomly selected computer scientists who may be required to sign a NDA. I have absolutely no interest in your "congressional investigation".

I haven't seen this "arguing that one should accept the claims on ideological grounds" that you're claiming

The assignment of "trust" to these intelligence agencies is ideological. Unless you're willing to provide some empirical basis for why we should "trust" them? Let's completely ignore that I've been asking time and again for such empirical evidence for their "trustworthiness".

"Frequentist" is the term for the "random event" type of probability, e.g. what frequency an outcome should be expected if the phenomenon is random. But you're right that it doesn't make much difference for this discussion; Caveman wants to assign an initial "probability" based only his distrust of the intelligence community itself, and then stop right there. That kind of "probability" is meaningless even if you assign it a number.
 
I've said that they are fallacious, which is correct. I've not said that they are all necessarily "unreasonable".

A fallacy is a bit of reasoning in which the truth of the premises neither entail the truth (deductive) nor the probable truth (inductive) of the conclusion.

To use reasoning in which the truth of the premises is not tied in this way to the truth of the premises is unreasonable on the face of it, not significantly better than a Magic 8-Ball and probably worse than a Ouija board (which has the advantage of really spelling out what we want to see).

You have also said, by the way, that any informal reasoning is not "meaningful reasoning". This is a phrase which is, ironically, meaningless, but is probably intended to be similar to "unreasonable".

Agreed. His notion that Bayesianism is how we should reason when we have incomplete information is bizarre. It is simply impossible for humans to behave thus, however interesting it is as a normative theory of ideal agents or as a program for expert systems.
 
I wouldn't hang my hat on that difference, if I were you.

There are various historical figures who are known to us only through the testimony of others. When a sufficient number of contemporaries agree that this or that fellow existed, and their accounts are similar enough, and if we there is reason to believe these accounts were written independently and without common prior (lost) source, then we ought to conclude it is probable the person existed (ignoring, of course, fantastical tales).

But we cannot reasonably expect any better evidence than such testimony.

But we aren't getting testimony. We're getting government agency heads or journalists telling us that unnamed persons who are experts have information that cannot be disclosed which gives them a 'high degree of confidence' that their proposed conclusions are true. Remember, government agency heads and CEOs go to Congress so we can see our representatives really kick up a fuss at them and shake their fists and show us what responsible stewards of the public interest they are.

Within the state intelligence and private high-tech defense sectors (to pick Clapper as an example), these guys are to some degree interchangeable administrators and if something too scandalous bubbles up, they tender a resignation and swap seats with someone serving on a few executive boards who suddenly need to extricate themselves from the private sector for a new government agency head opening up...

To go back to the Hannibal example, I can assign a high degree of confidence to his existing because I've seen numerous scholars describe detailed accounts based on similar primary sources like Polybius, Livy, Plutarch, etc. There is especially high value in the keen insight of such experts when they demonstrate conflicting details between sources and expanding the view to an entire primary source's tendency to bias their historical chronicles in predictable ways.

That imparts a far higher legitimacy than if I do not get to hear the scholars myself and the primary sources are off limits to me and every effort is made to seem as if there's not even a whiff of dissent.

I, like you, have no problem calling the Russian allegations probable and/or plausible.

I guess the underlying tension for me is that there's a different response in geopolitical terms for 'probable' vs. 'proven'. However, given Trump's callous attitude towards the issue, there isn't likely to be a hot-headed overreaction (well, not in that direction anyways).

I still think there's a slight chance this was an attempt by the intelligence community to give him a big shiny red button to push (which opens a flow of money and operational discretion) and keep his attention off of actual sensitive operations for a while. I think there's a chance he's playing it like a business man. When you get threatening legal letters (which he is also good at sending), you brush your shoulder off and say 'let them actually file their claims if they think they've got a case' (forcing them to reveal evidence so you can beat them up with it). Because it's the ones who respond at all that have made the first mistake, especially if they buy into the threats and act concerned. That's how he sees the world and that's why a lot of government institutions are going to be scratching their heads for a while trying to figure out how this country works now.

Of course. I'm not the one with the addled understanding here.

It doesn't entail that we should reject them. How does all this even work in your head?

"The moon is made of cheese therefor 2 + 2 = 4." This is a fallacy, therefor we should reject that 2 + 2 equals 4?

Similarly, it should be said, according to other statements of yours, you have not engaged in almost any "meaningful" reasoning in this thread.

That would be false.

For instance, on the basis of past CIA activities, you infer that they are not trustworthy -- an example of informal inductive reasoning. You really should take the time to give your full probability distribution over the set of meaningful propositions, so that we can see the outcome of your Bayesian calculations.

The burden of proof would be on the one claiming the CIA to be "trustworthy". I am perfectly free to argue that one should use a better standard than informal reasoning for this "trustworthiness", as well as using informal reasoning to contradict the claim of its "trustworthiness".
 
Okay, so you intentionally engage in what you consider fallacious reasoning throughout this conversation.

Yes of course. I'm not the one with the problem distinguishing between "fallacious argument" (ie there exists at least one interpretation under which the premises are true and the conclusion false) and "unreasonable argument".

Evidently, you don't care about reaching a reasonable conclusion, so perhaps we should end our conversation.

Yeah, sure. I'm pretty much the only one here who even seems interested in checking these claims (looking up malware source-code and what-have-you-not) as well as countering ideology-based reasoning, so clearly I am the one who doesn't care about reaching a reasonable conclusion.

Or perhaps I'll adopt a similar strategy, and use a Magic 8-Ball to compose my replies.

I'd much rather you stop substituting ideology for evidence. You want to argue that we should trust intelligence agencies? Then provide empirical evidence for it.
