Brief reflections on replies to my last post

[Note: After posting this entry, Burk informed me that this entry left out some of his arguments. Please read the comments section for Burk's added details and for our additional responses to each other.]

After re-reading the exchanges with Burk here, I wanted to clarify a few things.

I repeatedly pointed out that statistically significant psi-demonstrating studies have been replicated by different investigators in the same areas (e.g. EEG-correlation studies by different scientists have shown the same results, and I cited three of those studies for Burk). I pointed out that the effects are neither "undetectable" nor "barely above noise", as Burk had wrongly suggested (apparently without reading the literature). I also pointed out that some of these studies have appeared in "mainstream" journals (and by "mainstream", I mean journals that are affirmed by the U.S. National Library of Medicine). In short, I argued that the plethora of data support the idea that psi functions actually do exist.

Burk suggested that if these effects were really due to genuine psi, then at least some individual subjects should be able to produce the effects reliably – and by that he meant that subject X should be able to produce the same effects in multiple studies under the investigation of different scientists. Burk also went further by insisting that subject X should "be tested by all the skeptics in the world".

I have three lines of thought.

First I want to say that some individual subjects have participated in multiple studies with success in each (or most) of those studies. I can cite examples if necessary. I should acknowledge that so far nobody has been "tested by all the skeptics in the world", but that hardly counts as evidence *against* the idea that psi phenomena are real, and I think Burk is being unfair here.

Secondly, and more broadly, if indeed psi phenomena are real, then we should see their effects in multiple studies by independent laboratories. And, in fact, that *is* exactly what has been published. Burk has still not given us a reason for rejecting the replicated data. He simply mischaracterizes the effects as being "barely above noise", which is false and in any case would be irrelevant (see below). When multiple skeptics in independent laboratories do their own psi research, and then produce highly successful results, and then shift perspectives, well, I think it should be taken seriously. (I should point out that some skeptics produce successful results and still remain skeptical, but without being able to explain away their results)

Third, it doesn't really matter whether an effect is "barely above noise" – what skeptics want to know is whether or not the effect IS above the noise level at all. After that question has been answered skeptics will want to find out whether any conventional explanation(s) can explain the results, which is why we need carefully-crafted studies that rule out conventional explanations. But in fact, we already have such studies. I don't mean any offense to Burk, but he appears to be only vaguely familiar with the relevant literature.

Aside from that, I want to talk about Burk's exchange with a fellow blogger named "Goonch", who agreed with me by citing the alleged remote viewer Joseph McMoneagle. Burk disagreed with that specific example and cited an online article as proof that McMoneagle is a "kook". McMoneagle may or may not be a genuine remote viewer (he may or may not be a kook), but the actual link that Burk provided does not offer *any* evidence against him. Here's the article that Burk gave us: http://en.wikipedia.org/wiki/Joseph_McMoneagle

It's a Wikipedia entry. First of all, Wikipedia is not an acceptable academic source. But even if it were, I think it's remarkable that the wiki article doesn't contain any reasons for doubting McMoneagle's claims (or at least at the time of my writing: 8/10/09). In its section on "claims of accuracy" (the most important section for determining whether the man is a "kook"), Wikipedia says the following (quoted between the arrows):

>> McMoneagle provides a number of differing accounts regarding the accuracy of his remote viewing, varying from 5 to 95 percent[12] to between 65 and 75 percent.[13] McMoneagle has acknowledged that remote viewing is not always accurate, but says it was able to locate hostages and downed airplanes.[8] Of other psychics, he says that "Ninety-eight percent of the people are kooks."[8] <<

That's it. How did Burk arrive at the conclusion he offered?

Interestingly, wiki quotes McMoneagle's suggestion that most other psychics are kooks, but provides no reason for placing McMoneagle in that category.

My guess is that Burk's attitude comes from wiki's summary of McMoneagle's claims, and that his claims are *so* contrary to Burk's worldview(s) that Burk thinks his kookiness is just *obvious*.

In his book "Entangled Minds" (2006), Dean Radin claims that McMoneagle produced reliable effects in several double blind studies, and that these studies are available from the CIA upon making a formal FOIA request. I recently did just that, and am still waiting for an answer. I'll write a new entry after I receive a response. Right now I'm agnostic on whether or not McMoneagle is reliable.

Hi, Patrick-

Thanks for alterting me to your followup post. I think you are missing the forrest for the trees here. The strongest arguments I had made against the whole psi field were basically two:

First, if psi were real to any significant extent, it would be regularly observed, and it would have devastating consequences on many fields of endeavor, like casinos, stock markets, and theoretical physics, among many other fields where randomness and non-clairvoyance is not just the default assumption, but the entire basis of the operation.

Second, if psi research had found real phenomena, it would not be bothering with statistical issues- statistics are used to point to phenomena (think about the lod scores in genetic mapping studies, where very small scores are pointers to further work and refinement). A successful research program would, in the hands of its many adherents, not sit on the laurels of finding some occasionally replicable just-statistically-significant instance of psi, it would go on to refine its procedures so that this phenomenon can be demonstrated 100%, every time, time and time again, to all observers, skeptical or not skeptical.

That would be like using faint statistics to find a new subatomic particle in the smashups of a collider, then tuning the machine to the right energy for repeatable production, and finding a flood of these particles being made. It is simply unacceptable to plead that this field is special in some way and is for some reason unable to "dis-cover", or "reveal" its central phenomena in a more reliable way.

In field after field of reputable science, phenomena of some controversy, not to say ridicule, have been demonstrated not by tenuous statistics in secretive labs, but with clear, non-statistical demonstrations. We know from the drug industry, from government, and many other places, that statistics are frought with peril, and in a field that is so prone to ulterior agendas as is psi, the same process of demonstration is needed to overcome what in my judgement is entirely warrented skepticism.

Hi, Patrick-

Just to follow up, one of the classic cases with respect to my second point was cold fusion. Reputable researchers found statistically anomalous phenomena and convinced themselves first, and much of the world second, that these statistics indicated a wonderful new source of energy. Fine. That is about where psi research is today.

Then they tried to replicate the work in a more transparent way, others tried to do the same, and everyone tried to come up with better ways to show the phenomenon, as well a to explain it theoretically. Nothing panned out, though the original statistics certainly indicated what they claimed- anomalous phenomena.

Hi Burk, this is a long reply so I will have to do several posts. I wish the comments section allowed longer comments!

>> Hi, Patrick- Thanks for alerting me to your follow-up post. <<

You’re welcome :)

>> I think you are missing the forest for the trees here. The strongest arguments I had made against the whole psi field were basically two: <<

Sorry that I didn’t do a good job addressing your arguments last time around. I’ll try again here. I have also included a note in the main post explaining that my post failed to fully capture what you had been saying, and that readers should check out the comments section for details and for our responses to each other.

>> First, if psi were real to any significant extent, it would be regularly observed, <<

I think there are two mistakes here.

The first mistake is that you’re merely asserting what we would see/ wouldn’t see “if psi were real”. But how do you know? You’re making an assumption here without explaining the rationales behind it. How exactly do you know what we would see “if psi were real”? I think the question about whether psi phenomena are real should be answered by data – by experimentation – but not by assumptions. So we need peer-reviewed studies that demonstrate effects and which adequately rule out conventional explanations. In fact, such studies do exist and have been published. You dismiss these studies because of your distrust of statistical arguments, and I don’t think we’ll ever agree on the statistical issue, but I’ll briefly try addressing your skepticism later on.

The second mistake is that you’re assuming what people actually observe/don’t observe regularly. The interesting thing is that a lot of people *do* regularly observe psi effects - or at least claim to - and this includes various examples of telepathy.

>> and it would have devastating consequences on many fields of endeavor, like casinos, stock markets, and theoretical physics, among many other fields where randomness and non-clairvoyance is not just the default assumption, but the entire basis of the operation. <<

Those claims really need more meat IMO.

First, how exactly does theoretical physics require “non-clairvoyance” as “the entire basis of operation”? At any rate, the question about whether clairvoyance is ever real cannot be answered by pointing to the consequences of clairvoyance being true. You appear to be basically saying, “If clairvoyance were true, then it would be a pain for theoretical physicists”. But that is no argument at all. Did you have something else in mind when you wrote that?

(continued...)

Paprika said...

Second, you also appear to be saying that if psi capacities were real then people would be using them to beat casinos and the stock market, which brings me to my second point. If psi capacities are real then people may be subconsciously competing with each other with those capacities, and there may be a sort of canceling-out effect. Casino owners would certainly not want people to beat out their casinos, and so the psi functions of casino owners may be competing with those of the visitors.

Third, you’re also assuming that *nobody* *ever* successfully uses their psi capacities to beat casinos, but others disagree with you. I dont think that everybody can do so, but that is not an argument against the idea that psi effects are real. Rather, it shows a current limitation in what people are able to do.

You went on to argue that if psi phenomena were real then they would be *more* than simply “occasionally replicable [and] just-statistically-significant”. You wrote:

>> Second, if psi research had found real phenomena, it would not be bothering with statistical issues- statistics are used to point to phenomena (think about the lod scores in genetic mapping studies, where very small scores are pointers to further work and refinement). A successful research program would, in the hands of its many adherents, not sit on the laurels of finding some occasionally replicable just-statistically-significant instance of psi, it would go on to refine its procedures so that this phenomenon can be demonstrated 100%, every time, time and time again, to all observers, skeptical or not skeptical. <<

I think there are few problems with this argument. For one, you’re once again presupposing what “real” psi would look like. It may take 100% reliability to convince *you*, but it is perfectly rational for others to conclude that psi effects are real based on the available data. I don’t think we’re going to agree on the relevance of statistics, but I happen to think that odds against chance of several-trillion to one are worth paying attention to. You appear to think otherwise. Perhaps we’re at an impasse on the statistical issue, but I would still like to offer the following analogy to help explain how I see the situation.

Let’s say we’re investigating an anti-inflammatory drug named Medicine X (MX for short). We want to know whether MX actually works, so we set up a double-blind trial in which two groups of 20 subjects (all matched for age, sex, etc.) receive either MX or placebo. At the end of the trial we find out that subjects taking MX have less inflammation than subjects taking placebo. More specifically, let’s say that 80% of MX-recipients have reduced inflammation compared to 22% of placebo-recipients who have reduced inflammation. We do *not* see 100% reliability in MX’s effectiveness, but we see more reliability than placebo’s effectiveness.

Now let’s say that the results are replicated by another team of investigators.

Ok, how do we know whether or not subjects taking MX recovered by “chance”? Well, it is very *statistically* unlikely given the way the trials were set up. It is very statistically likely that MX actually works. But somebody may still come along and say something like the following: “If MX actually works then we would see results in everybody – in 100% of MX recipients.”

Well, it may take 100% reliability to convince some people (e.g. the makers of some competing drug), but it’s still perfectly rational for others to conclude that MX actually works based on the available data.

Likewise, we do not see 100% reliability in demonstrating psi effects, but I don’t think we need 100% reliability to determine whether psi effects are real.

Paprika said...

Additionally, I want to make one more point before moving on. It seems that some psi effects are indeed clear-cut, including fMRI correlations, EEG correlations, and some psychokinetic effects. In some cases we can actually visually see discernible effects that are replicated. I discussed EEG correlations before and I gave you a few references to check up on. More refs could be given upon request.

>> It is simply unacceptable to plead that this field is special in some way and is for some reason unable to "dis-cover", or "reveal" its central phenomena in a more reliable way. <<

I’m not making that plea. And somebody could just as easily apply what you said to medicine (e.g. we do not see 100% reliability in drugs that most likely *do* work, even in cases when we can’t say why/how they work).

>> In field after field of reputable science, phenomena of some controversy, not to say ridicule, have been demonstrated not by tenuous statistics in secretive labs, but with clear, non-statistical demonstrations. <<

As I tried suggesting earlier, I’m not sure that there is such a thing as a purely non-statistical demonstration. And again, I think there are indeed some clear cut examples of psi, which is what I think you’re asking for.

>> Just to follow up, one of the classic cases with respect to my second point was cold fusion. Reputable researchers found statistically anomalous phenomena and convinced themselves first, and much of the world second, that these statistics indicated a wonderful new source of energy. Fine. That is about where psi research is today. Then they tried to replicate the work in a more transparent way, others tried to do the same, and everyone tried to come up with better ways to show the phenomenon, as well a to explain it theoretically. Nothing panned out, though the original statistics certainly indicated what they claimed- anomalous phenomena. <<

There are a few problems with this argument as well. Psi research has been going on for over a century, with ever-improving methods of investigation, and the results are *still* very significant and in some cases quite repeatable. If scientists are able to get cold fusion to “work” repeatedly after a century of ever-improving methodology, *then* you can compare cold fusion to parapsychology.

Okay, enough rambling from me!

Best wishes

Here you will find a study of Joseph McMoneagle:

http://www.mceagle.com/remote-viewing/IntentionAttentionExpectation.pdf

"Joseph W. McMoneagle has participated in 44 on-camera demonstrations of remote viewing 35 of which would be considered as successful; that is, if they had been assed by the usual blind rank-order method, they would have easily been ranked correctly in first place.

With all due respect, Patrick, you're wasting quite a lot of energy on this jerk. You should have told him right from the beginning that if he posts anything on this board without reading the relevant studies first than he will be banned. That's how you deal with jerks who are so disrespectful that they can't even be bothered to read the research. You also should not waste valuable energy debating with someone who uses arguments that he knows are just plain bad and would never fly if the shoe was on the other foot. You will almost certainly not convince someone like him - he is not interested in being convinced. You should be putting your effort into figuring out ways to punish skeptics like him for their unreasonable, disrespectful, and just plain immoral behavior. If I was able to galvanize all of the non-mainstream researchers of all fields to unite in action against the skeptics we could break their movement in half. I believe that we should stop fighting (and in many instances losing) this war of attrition by arguing with these skeptics who will never change and start treating them like they should be treated - as enemies. Organizations like SCEPCOP and Skeptical Investigations are a good start, but they need more support. Hopefully they can get something going...

Burk said...

Hi, Patrick-

My email has out for a couple days- sorry about not responding. I'd be interested in specifics you could point me towards on ...

clear-cut effects in ... psychokinetic effects

Visually discernible effects would be especially appreciated. I'd like to hear more. My local library is pretty well stocked, though probably not in this field.

Burk said...

Hey, Antiskeptic-

It would be helpful if the SCEPCOP site used less new-age art (and guns) and more data. Atlantis rising? Give me a break! - what a way to gain respect for your cause.

Suspension of judgement is not meant to be a permanent condition, but a temporary one while a phenomenon is investigated. Thereafter, critique (judgement) is of the greatest importance, and those phenomena that withstand reasoned critique used to do more investigations. Those that don't, aren't.

Antiskeptic, you wrote:

I appreciate your concern, BUT I take issue with you calling Burk a "jerk". If you think talking to Burk is a waste of time, then that's fine. You may or may not be correct, but I'm trying to maintain a civil dialogue here, and name-calling doesn't help. So for future reference, please either refrain or don't post at all.

>> You should be putting your effort into figuring out ways to punish skeptics like him for their unreasonable, disrespectful, and just plain immoral behavior. <<

Well, I'm not sure how I would go about "punishing skeptics like" Burk. What exactly did you have in mind?

I suspect that Burk will *not* be convinced by the data, but I still wanted to address some of his points for two reasons – first, so he would better understand my own thinking, and second, so that readers can see how a "psi proponent" would handle some objections.

And for the record, I actually do *not* think that Burk is a jerk. I do think he's being unfair about the data, but that doesn't mean he's a jerk. Many creationists are unfair about the data on evolution, but many of them are also great non-jerk people.

(And yes, I am equating denial of psi with denial of evolution...)

take care

- Pat
