Audio Critic

I've asked this question once before, but it never got answered, and it still seems worthwhile:
Wellfed, what listening experience(s) would it take for you to finally say to yourself "Well, I thought I was hearing a difference, but I guess I wasn't"?
This has nothing to do with any protocol, I'm just curious.
 
Clarification of "Tube Failure" issue

Friends,

I thought of something that first occurred to me two days ago and was forgotten, not making it into any of my critiques of the protocol.

I am concerned about the issue of "Tube Failure".

Tubes may have soft, progressive failures; sudden shorts or opens; and conditions that are so traumatic that they can fail and take out other part of the circuit. A tube failure is less likely in a voltage amplifer, and more likely in a rectifier or output stage. Furthermore, bias circuits can fail, causing tube failure; and shorts or leakage in coupling capacitors can cause a cascade of failures.

If (say) one of the output tubes in Wellfed's system fails noticeably -- becomes gassy; develops a short with plate heating up until it's red; develops a heater-to-cathode short -- the failure would in my mind, I'm afraid, invalidate the test results up to that point, because it is likely to have affected the sound for a while. One can never quantify this predictably. Tubes do not necessarily go from "100% working" to "100% dead", instantly. Soft, progressive failures can lead to an increasing loss of output or nonlinearity, crossover distortion, soft clipping, etc. And this might go on for a while, and stabilize. Or, a tube might "pop".

Tube failure should be considered with more precise attention (and how about other failures, not dissected precisely: just "Wellfed's audio system dies"?)

If Wellfed was using a very stable solid-state amp, and solid-state preamp, with no past history of failure or instability and no tendency to blow even on overloaded volume peaks, then I would not even have THOUGHT of the issue of how to deal with a catastrophic failure DURING a test; my mistake but one based on the fact that it has never occurred that way during testing that I've done (though I have had some embarrassing failures: like a blown electrolytic in an audio processor being tested at an ABC-owned 50,000 watt radio station, resulting in about 80% steady modulation of 120 Hz until the transmitter tech jumped up and plunged in a patch cord! You can imagine the egg on our faces...)

I still have at least one tube amp (and in fact had to repair a leaky capacitor and overheated resistor in it, last week.) And I've used tube equipment all my life (but not exclusively) and experienced "the usual expected failures" and need to replace parts. They are great devices but are not, unfortunately, always reliable.

I ask for the opinions of people here, and Wellfed. Will a "significant perceptible tube failure, degrading or cutting off the audio and disabling the test" result in a:

1 -- loss of confidence in the prior parts of the test?

2 -- result in Wellfed losing confidence that his amp will be fully functional during the REST of the test?

3 -- necessarily going to have only tube failures that can be described as "sudden ones" that are "immediately repairable by replacing tubes and adjusting bias current"?

I would think that the answers are:

1 - possibly, and maybe likely;

2 - possibly;

3 - Definitely not; tube failure can cause, or be caused, by a cascade of failures of other parts in a high voltage circuit, and the amp should be competently repaired before being relied on in a critical test.

If my conclusions are reasonable, how do we control for "tube failures"? We can --

a. Ignore the possibility;

b. Keep the protocol as it is, right now;

c. Treat the failure as one that might be more serious than merely "1 blown tube", requiring competent amp repair or at least manufacture-recommended testing using a scope, wattmeter, etc. We can stop the test altogether and declare it null and void and resume ONLY when the amp is performing with absolutely known, normal stability.

d. Provide an alternative amp; stop the test; nullify the prior results; and start the test over with the alternative amp, keeping it in use for the REMAINDER of all tests.

e. Other -- you make a suggestion.

I think that I have covered all reasonable grounds here to make people who think I am a "spy" who is trying to "invalidate the test by overcomplating it" satisfied that they could agree to ignore me and opt for (a) or (b) above.

I would add, however, that if I were the test coordinator, I would not chose (a) or (b).

Second response to Pup

I am replying to one short post by Pup, which I copy below in its entirety, to prevent taking anything out of context:

What's with this "propagandists" stuff? You asked a question that I didn't see anyone else had addressed yet, so I gave an answer. No need to shoot the messenger. If someone else has a better explanation for the accusations, I'm sure they'll chime in.
------------

Pup, your original post directed as a question to me was perceived by me as being highly aggressive and sophistic: a splitting of hairs about one detail in one sentence of the lengthy material that I have contributed that contains many details about neurophysiological and acoustical and electrical testing. It was about a side issue, too: a paranoid accusation that I was a conscious misleading and lying fraud, pretending to be PianoTeacher but (allegedly) someone else who might even be trying to wreck or subvert the test.

As I said earlier, I have no power by means merely of typing words in the browser field of the Randi forum, to "satisfy" you on this matter. We'll have to stipulate that. I am not "another person", nor someone out to subvert the test. You may continue on, as desired, with your side of the matter and I have essentially no choice but to ask you to accept my explanations and assurances. If you wish to make a formal objection to Kramer, he knows how to contact me -- he has the power to reveal what he might find out, and inform the forum participants what he might discover.

I have already explained to you that I wish to focus on real issues. You are ratcheting up another side-issue unrelated to the protocol, and I would rather not even address it.

This is not meant with disrespect, so please accept my apologies if you have any suspicions about that. I welcome you to the discussion, as long as you help us all focus on THE TEST PROTOCOL.

Thanks,

To Zaayrdragon: about instrumental tests

Zaayrdragon queried:

>
So I take it, then, that no proper instrumentation testing has been revealed for the GSIC?
<

Apparently, not. I proposed some specifics but either they were ignored, or dismissed, by -- so far -- everyone else.

I had a tentative general suggestion for a protocol for TESTING THE CARRIER ITSELF by automated means, to verify GSIC maker claims.

I also had proposed testing Michael by using an "instant A-B" type of alternation of synched musical passages -- the way I used to conduct tests, using open reel analogue tape masters -- or by using an ABX methodology, to discern if he could claim to hear fine distinctions.

Apparently this too fails to trigger any enthusiasm here.

These two protocol substitutes -- which I only STARTED to suggest and did not flesh out -- would be, in my opinion, better tests that could stand a change of making some kind of determination by scientific processes.

The CARRIER TEST (i. e. compact disk either treated or untreated) would likely be beyond the scope of JREF, unless they have advanced digital electronic analysts, computer-driven instrumentation and data analyzer recording capability, and a statistical analysis team "ready to go".

The AB, or ABX test of Michael's attempts to evaluate "treated" and "untreated" CDs could certainly be done, and in Fargo.

That kind of test was not contemplated by Michael, who only has focused on -- my own summary here -- ' playing some parts of CDs, for an extended period of time, by changing the test samples in ONE control player, allowing for interruption delays, and permitting Michael to adjust a remote track control, and a remote volume control' (again, my summary.) I find this objectionable, and poorly controlled, and not in conformance to known audio test practices: "rigged" (my word) to fail. And, unfortunately, it was proposed by Michael, who wants to succeed.

Reassurances addressed to Pup

Pup,

I have reported the possibility to moderator Kramer that you may seriously suspect that I am masquerading as someone else, and allegedly trying to subvert this test.

I have already given JREF pertinent information about me in order to register. However, I just sent Kramer my name, occupation and position, business enterprise, address, zip code, and telephone number; and my email address.

I have asked Kramer to contact me in person. I wish to keep my private information off this board but perhaps if Kramer can ask some questions that your taking up the "fraudulent subverter?" challenge might suggest, we can resolve your suspicions.

Yours truly,
PianoTeacher

For Zaayrdragon

Zaayrdragon observed:
>
Another thing just occured to me - if this chip does all that, why isn't a permanent version made? And why aren't recording companies using these at the production end, and charging more for the finished disc, to permanently improve the sound quality, like the G.S. website claims?
<

I addressed this thoroughly perhaps two or three days ago. There was some but not much response to it then, so it apparently does not seem to be an idea that appeals to forum posters as a practical commercial consequence of the existence of such technology, that would result in FAR greater profit to GS than selling a few of their thingies, although at least one person beside you and me seems to think so, too. It seems to me that they are so extremely convinced that there is no possibility of GSIC effect that even proposing THOUGHT EXPERIMENTS about the possibilities angers and frustrates most of them, some of whom have lashed out at me quite sharply!

The general point of view, as perceived by me, is that most of the participants are unwilling to think about "nuances" and fine details, even in thought experiments designed to adjust the protocol. They are EXTREMELY BIASED against GSIC (as I am!!!!) and yet are often quite blind, in my opinion, for the need to control for any such biases.

You will note, Zaayrdragon, that the general character of contributions to this forum discussion seem to have little focus on the protocol, and have failed to do much more than mess around with side issues that can never be resolved here in a colloquial forum where we aren't working face-to-face. No one has replied to my request that any audio engineers or actual experienced scientific testers might speak up and identify themselves. No one apparently is willing -- even in general -- to talk about their occupations, if relevant to the issues of hi fi, electronics, music testing, and sound equipment engineering. No one beside me has given much of a personal bio. I have almost no idea if anybody else here has ANY actual semi-pro experience with high end or advanced hi fi: one person retorted that this was utterly irrelevant.

It seems to me that the forum participants are indeed very concerned about getting a protocol finalized and having a test. Many have "pressured" and hectored Wellfed about things he is struggling with. Some have suggested that he is doing this to "trail away" from the test. I don't have any firm evidence from that; I think there is a cultural/scientific misalignment between Wellfed and some ardent impatient skeptical rationalists, and that Wellfed isn't use to thinking about music and sound evaluation THEIR ways.

I have tried to discuss the flavors of personality types observed here: The Believer, the Skeptical Agnostic, and the Skeptical Rationalist Atheist (with subsets of Dogmatic Skeptical Atheists, and Aggressive Impatient Dogmatic Skeptical Atheists). We aren't all lining up and communicating effectively and cooperatively.

Zaayrdragon: your sophisticated observations intrigue me. Care to add any personal information -- even very general stuff -- that might interest us all?

Response to Beleth about his personal test speculation

I have a query from Beleth, who directed us to a post at the end of page 16 and asked me to answer it; unfortunately it is NOT there on my browser at the end of P. 16 now, but I think this is what he wants my opinion about: I quote the entire section below:

Beleth comments:
--------
Here's another thought experiment. Say I have a CD. A representative of the JREF "treats" it by playing it on a car stereo and holding a dictation-style tape recorder up to the speaker in the driver-side door. That representative then copies that tape recording to a recordable CD, obscures the labels of both the original CD and the "treated" copy-of-a-copy, and gives them to a second person who will put them into my (decent but by no means audiophilic) home stereo system for me to listen to.

I assert that I will be able to tell the difference between the untreated original and the treated copy 100% of the time. In fact, I will assert that I can do this ten times, with ten different CDs, and accurately be able to tell the difference all ten times.

No one runs any technical audio tests on it. It's just me, my ears, and neurochemical changes in my brain caused by pressure waves of air entering my ears.

What's the difference between this test and what Michael is claiming to do?
---------

Beleth, you apparently missed exactly TWO explicitly comparable examples given by me earlier that I posted, to describe "sound quality variations" that I (a retired pro sound tech and engineer) know I too could reliably identify, ten out of ten tries.

You and I both thought of this though I did bring it into the context of my discussion of the likelihood of reliable identification of samples earlier -- at least two days ago, I suspect.

I did not provide examples of secondary sound recording copies that were degraded NEARLY as much as you have suggested. But, no matter: you, and I, could RELIABLY, ten out of ten times, identify WHICH CD was being played back (assuming that the original first source CD was not, say, the Mapleson cylinder recordings made at the Met in 1906!) A good quality average stereo recording on CD, if copied your "lossy" way, with introduction of severe sound coloration, would be EASY AS PIE to identify.

I have read about the GSIC and it is my impression that ASSUMING THE EFFECT IS REAL AS CLAIMED, the alleged improvements would probably not make the so-called "treated" disk sound as perceptibly different from the untreated one, as a good stereo CD that has been copied via a car stereo speaker picked up by a pocket dictation recorder. The latter A-B difference is GIGANTIC. If the GSIC indeed DOES make *that much difference* then it is likely for Michael to pass the protocol ten out of ten times!!!!

However, the evidence we have so far tends to contradict this. Michael has expressed that he can become uncertain under various conditions, and that apparently he wants very much to select optimal musical material. Now, in the test you propose, as I said, just about anything NOT SILLY like the Mapleson cylinders of 1906 will quickly reveal the differences, instantly, and to just about anybody who takes YOUR test and hears a clean original CD, versus music played thru a car radio onto a dictation machine.

Therefore I suspect that the differences that Michael tries to perceive are much more subtle than the ones in your theoretical test.

Other factors lead me to conclude this, as well. The GSIC is being marketed as a tweak for high-enders. Your test is not relevant to the fine discriminations of tonal differences of extremely superb high quality audio; low quality BUT NOT SILLY audio (i. e. Mapleson cylinders) could suffice.

I do often hear remarkable beauty of sound from high end systems. I have no objections to the existence of the social phenomenon of "high end audio", nor to its practitioners. Many are very rational and practical. A lot of far-out people have certainly exploited the Internet, though. At one time I might have called myself "on the absolute bottom rung of the lowest circle of Hell of high enders". (I owned Studer/Revox, Nakamichi, and other respectable equipment.) But in later years I have directed my funds toward expensive digital keyboards and music CDs, not to endlessly upgrading my equipment. De gustibus...

I am not biased against hi end audio; though I am biased against hi end nonsense, and am EXTREMELY biased against hi end fraud and exploitation.

Does this answer, and amplification of my biases, assist you in an informative manner?

The answer is "none of the above". This isn't a science experiment. It is a challenge to prove that an amazingly extrodinary unknown paranormal event has occured. Like someone turns lead to gold with the wave of a wand, or correctly predicts lottery numbers every day for a month, or makes objects move with thier mind. This is a challenge to prove something paranormal.

The challenge is that a protocol is set, the tes is run according to the protocol, and either the claimaint succeeds or fails. It doesn't matter whether the claimant failed because of bad tubes, blown speakers, cold weather, bad concentration, or whatever. Generally a test of a paranormal claim will call for asking before the test whether the conditions are accpetable to the claimant. The test is run. If the claimant fails, the claimant should have an opportunity to explain why it failed. ("I think I could have done it, but the tube went bad.") In the case of the JREF challenge, the claimant can apply again in a year and take another shot.

Many people (mostly applicants) seem to confuse the challenge with an opportunity to conduct a scientific experiment. PianoTeacher, you seem to have wandered into this confusion. Everything you have posted seems very reasonable to me for conducting actually sceintific experiments into the effects of the chip--but that ain't what the JREF challenge is about. Its about the claim: the guy says he can hear a difference. The challenge is to prove the claim. :)

I wish someone would test the chip under the conditions that you proposed. It's just not within the purview of a JREF challenge.

I can say that I did appreciate your posts (even if I didn't read all of them all the way through). You seem to have a good idea on how to really test this chip. Maybe you could introduce your thoughts to others in the audio community and see if someone can really do a decent test on this thing! :)

That reply by DevilsAdvocate to my concern about the exact impact of "tube failure stopping the test" is quite a persuasive argument in its full context in his original post.

I proposed my concerns as a set of inquiries rather than an oracular declaration of mine. I wanted other opinions.

The very fact that DevilsAdvocate and many of the rest of us are aware of the ways that people try to deflect their failures to win the Randi Challenge is addressed by his well-argued response. But I am not entirely happy about ALL of it of the entirety of his response.

If I lose some "hard edge" here as a Skeptical Rationalist, I have to say that as a retired audio engineer, I would be quite sympathetic to Wellfed if, say, a storm caused a power failure in Fargo. He'd fail the test, per DevilsAdvocate's strict constructionism. I just personally could not hold that against Wellfed. I might think JREF could have the decency to wait til the lights came back on, at least for a reasonable time. Furthermore, suppose a pentode output tube suddenly fails because of a breakdown in HV tension across the grid blocking capacitor, slamming 300 volts onto the control grid. SUBSTANTIAL PERMANENT DAMAGE would result to his power amp, and it would not be restored to operation by plugging in a new tube.

This audio test involves high tension electricity and complicated equipment, not merely two twigs held out at arms' length.

I also would not hold it against Wellfed, nor consider that this failure meant "he lost the Randi Challenge" unless we had explicitly drawn up some slightly more general conditions, in a few words, and included this in the protocols for the Challenge, wrt "tube failure".

So, once again: what happens if the amp TOTALLY SMOKES? I guess if we mention this in the protocol and Wellfed agrees that his test is immediately and permanently terminated and, per Devil, "the claimant can apply again in a year and take another shot", then we're all on the same page.

As I understand it, the protocol does not address the tube failure issue other than to state that an interruption will be allowed to plug in a new tube and adjust bias. This seems to me NOT to cover worse failures. And my own experience with tube power amps is not very encouraging, considering what just happened last week to mine!

Can you suggest one extra sentence, or clause, to add to the protocol with respect to tube failures, that will address this small concern of mine?

Remember Murphy's Law. And *I* still cannot forget what happened one fine day at KGO when the cap blew during a test I'd struggled for months to accomplish.

Furthermore, it is AN ABSOLUTE REQUIREMENT OF THE TEST for normal AC power to be "on" at Wellfed's house. I don't know about you folks, but in rainy weather sometimes we get brownouts or blackouts even here in San Jose, especially around twilight: plays havoc with all the PC's in our music labs, necessitating UPS devices on each one! My wife's Diskclavier goes dead during a lesson; it's her "accompaniment" piano! I don't *blame* her for that!

AC power, and a working amp, are both absolutely REQUIRED to conduct the Wellfed attempt to win the Randi Challenge. Is the language of the protocol quite bulletproof, with respect to these requirements? I am not suggesting this to "create an out" but to achieve an agreement GOING IN.

I would have to agree. The thing is; I am trying to eliminate flaws (translated escape portals) to the best of my ability. The conditions under which this test is conducted is of primary importance to me. I never said this would be an easy task.

I have considered being my own observer, but was advised that what I had in mind would not facilitate the scientific validity of the test. It also has been suggested that my idea would not be a true double blind arrangement.

Here's my idea. In my last protocol T1 was to take the GSIC, real or dummy, to my listening room and facilitate the "treatment". Would there be anything wrong with T1 leaving the GSIC or the dummy in the listening room after the treatment has been applied and then after I make my determination uncover the device to reveal its status, active or dummy? I personally don't see where this would screw up the double blind element as T1 would not know the status of device until after the fateful determination is made. If this were acceptable I wouldn't see the need for me to have any of my own observers present. This would also have the benefit of ending the test immediately if I failed with an identification. This would also eliminate the need for the bedsheet "blind" Kramer has called for. Hopefully this would also eliminate at least 1 JREF observer from being necessary in my listening room. I would actually like to have no JREF observers present if possible. Wouldn't unmanned video cameras prove to be a satisfactory control against cheating?
 
(on ignore)

Going on 18 pages and counting.

Piano Teacher is doing his very best to focus on specifics but it's too hard distilling the essence from his overwhelming volumnious verbiage.

Who said this?
"But the claim is not: The GSIC works."

Sure it is. That's it exactly.

From Michael Anda's claim letter:
"My review of this device at Audio Asylum is also a topic of discussion at the www.randi.org discussion site where I am ridiculed for claiming to hear an effect using the GSIC."

"hear the effect" = "I disagree the GSIC is a fraudulent device, and I claim that it works as advertised."

At this late date, anyone that thinks this is not a GSIC-validity test has really got to go back to square one.

=================================
BTW <<< placing the GSIC in an envelope is not acceptable. It must be placed on top of the transport directly. We have reviewed the reasoning for that in excruciating detail, so it blows my mind to see Mr Anda now start to do some investigation "as called for in the Steven Howard Protocol" ( a protocol that was discarded).

Also, z-dragon offered the opinion that:
... there's no need for a dummy chip at all. Just use the GSIC on any ol' CD player, treat 10 discs, don't treat another 10 discs, and bring the discs alone to his house for trial-and-error time. Two copies of each disc. One treated, one not. See if he can tell the difference. The GSIC need never be in the home at all.

IIRC, a variation of this was suggested, with a safe-deposit box in Florida. I can't even begin to review the convoluted record about that now, but I do know that the idea keeps popping up that Wellfed has to be the one to actually do the GSIC treatments (and he has to actually start and stop the discs being GSIC'd after 5 seconds with his remote control) and Wellfed keeps putting the two-marker system in his protocol at this late date (despite it being ruled out by James Randi in the very first exchanges of communications).

I post this, in the realization that Wellfed has me on ignore (referring to me as "you know who" as if I am not adding anything useful to the discussion).
The fact is, I made several important observations, and in those cases, the challenge admin. clearly noticed my comments which then caused KRAMER to FUBAR the protocols, so no wonder Anda put me on his ignore list!


Well, here it is Tuesday again, and another week is whizzing by without anything to show for it.
 
Just add perhaps one sentence about failures of power, and of audio gear

I have thought over for a while the replies DevilsAdvocate gave related to my worries about a poorly-defined or inexact treatment of what a "tube failure" might be.

In thinking over his comments, and my initial reply, I would like to amplify my concerns just a little bit. I am, after all, a retired audio engineer! I've had my share of frustrating breakdowns at critical moments (not always during tests, mind you, but enough to stick in my mind!)

What has Mr. Randi's experience with "equipment failures during tests" tended to indicate as a practical course of action? Has this ever happened before? Has a typical Randi Challenge test involved a very complicated tube operated device?

I would profit from his advice or that of JREF test administrators; I am not sure if DevilsAdvocate IS indeed one; he may be. He writes confidently and lucidly like an experienced person!

Can we craft one comprehensive sentence that provides a concise, and more explicit, description of "tube failure" consequences, and add it to the protocol? It can have two parts: tube and/or audio system irreparable or temporary failure; and AC power mains interruptions. Just a sentence, not much longer than fifteen to twenty well-chosen words that we can agree on.

For instance: we get, as I said, brownouts or even complete momentary power dropouts or some that are perhaps 1 to 5 minutes long, during the rainy season here in San Jose during winter -- unpredictably. How would such an event affect the Wellfed trial? What would be the rule or protocol stipulation?

As far as protocol is concerned, the guy has his shot to prove his claim. Amps smoke, lightning hits his house, whatever. He fails--according to protocol. It would be at the discretion of JREF--not the claimant--to allow exceptions to the protocol. JREF spends a lot of time setting up these tests, and requires peoples precious time to conduct them. It would not be fair to JREF to require that a multitude of possible conditions would extend the test time for an unknown or indeterminate period of time. These are things that I expect Kramer might refer to as "vanities". JREF is offering the million bucks. You agree how to do it. If you have problems--that's your problem. If the power goes out, I could see JREF making an exception to extend the time (if it is possible). But that should be an exception offered by JREF as a decency--not a protocol requirement. And I wouldn't expect much leniency for something like "gassy tubes". :)

I *might* accept that from James Randi, if he cares to boil it all down to such a declarative statement. It would make me feel, I guess, just a little bit disappointed.

(I am not, indeed, claiming that you -- Gr8wight -- make that assertion *specifically*, so I do not attribute a straw man argument to you. It might be possible to infer that by going one or two steps forward, however, which isn't necessarily your intention, or fault.)

Furthermore, if one suggested that the Randi Challenge has absolutely no legitimate scientific significance, that seems to me to contradict the evidence given in the careful recounting of Randi's involvement in scientific tests via his published books and articles on this site, as well as his participation in "Nova" investigations of paranormalism in Russia.

I tend to believe that he has a broader view than what you say, and understands the larger perspective. He has analyzed the potentials for the possibility of losing the million dollars, and very intelligently weighed those possibilities against paranormal claims, which so far seem to be clumsily and ineffectively tested only by "paranormal investigators", including some academic psychologists: the only ones seemingly able to offer any argument, let alone evidence.

These people are so stuck "inside the paradigm" that they have difficulty employing rational skepticism, applying controls, and doing unbiased analysis of results.

My impression in reading Randi's books over the past twenty years (and those of his friend and colleague Martin Gardner) is that he is an expert in misdirection and chicanery who has come to learn that this is the trick most often employed by charlatans; and he knows how to suggests controls to neutralize it.

When his control protocols are employed in scientific tests, misdirection and chicanery tend to be eliminated.

So far, the scientists and investigators benefiting from his advice have not succeeded in confirming paranormal claims; ergo there is no prize awarded. That is about all a scientist could claim for the absence of a "win", as the Randi Challenge is not equivalent to the same exhaustive process that has, for example, tested Slipher's and Hubble's red shift observations over the past 80 years.

But, give him credit that is due: Randi is one helluva smart guy -- and a very warm and humane one -- and I admire him. I think he is doing good things, and will be remembered for that.

What Randi seems to have done is to offer a kind of amateur scientific prize, in parallel -- say -- to the Nobel prize. And the means to acquire the prize is the sought-after jumping of the yawning chasm before us: into the realm of unexplained, or misexplained phenomena and self-delusion. As a matter of fact, only recently have physicists begun to explore ASPECTS of that chasm, via string theory, multiple universes or dimensions, propositions of actions at a distance by means of quantum superposition, and so forth. But their studies are so arcane, at present, that the general public does not typically understand them, and can't be deeply interested in explanations and evidence offered only in complex equations and mathematical constructs.

I personally conclude that the motivations are to increase the rationality present in the world, and at the same time to decrease the irrational, nonverifiable mythologies, and thereby advance useful scientific knowledge that can help promote social progress.

I tend to feel that by summarizing Randi's prize and Challenge in a very narrow pathological manner, isolating it from scientific intellectuality, is an incomplete view of it.
I have not found evidence from Randi, directly, that has convinced me that it is a negative process, perforce designed essentially to damage the comfortable smugness of sincere Believers, or the scams of con artists, but otherwise accomplish nothing else.

The Randi Challenge, so far, has not been accepted by reputed scam artists and cons, for obvious reasons: therefore, its existence acts as a moral moderator and standard. It demonstrates that con artists, liars, and frauds -- all of whom are greedy -- have no tools with which to acquire the $1,000, 000, some of them being probably so sociopathic that they might -- under certain conditions -- STEAL this money, if they could.

Since they cannot steal it, nor persuade the Foundation to turn it over based on mythological untested assertions and propaganda (aided by misdirection and chicanery), they don't win the prize. That is a kind of "given" and was figured into the original concept.

A second group of potential applicants is the confused and/or sincere Believer, who does not intentionally cheat but is merely incompetent (possibly also deluded.) The prize motivates them to discipline themselves to try an unusual challenge the like of which they have NEVER before submitted to in life. Rarely, an applicant presents a useful and acceptable protocol; rarely does a test occur; and never has the prize been awarded. EVEN THEN, some of these Believers have not learned anything about themselves, their systematic errors, their self-delusions.

The third group of persons "involved" in the Randi Challenge, and with James Randi's remarkably clear powers of expression, are onlookers who are interested in the issues upon which JREF and Randi focus. Some may be upset; some may feel validation; some may receive tools of logic by which to think themselves into a change of mind, acquiring greater insights. This group is far larger than the relatively tiny number of "tested dowsers" and "never-tested con artists", and Randi obviously wants to communicate with this vast public.

He does it with with, cleverness, open-minded freshness, and patience.

Many in the public, worldwide, have learned something from James Randi et al., with rational knowledge advanced and human reasoning improved...by a step at a time.

I'm sorry, wasn't that pretty much exactly what I just said, only with four times more words,most of them about yourself?
