Wiseman simply went to the authority on the matter, asked for the best, and used those folks. He probably thought he would get the least argument that way, especially since he is a skeptic, but of course that was not to be.
| I do accept that point, assuming Wiseman asked for the best. (I doubt very much he would have got the best mediums around from such an enquiry).
If we compare that with Schwartz. What Schwartz did was try to track down popular or well known mediums, let the mediums work under lesser controls close to their natural environment, see how they do and increase the controls gradually. The goal here is to understand what is going on, which is legtimate methodology for trying to understand any phenomenon. Wiseman on the otherhand isn't really looking in any depth at all.
Schwartz can perhaps be crticized for not jumping stright to a 'triple blind' protocol but what is the point if he hasn't even tested what occurs under lesser, simpler controls? Schwartz commented '..... statements made by Wiseman and O'Keeffe that do not acknowledge the fact that the same issues were previously discussed in Schwartz et al. as possible questions for future research.... Quote: |
Perhaps Wiseman did not realize this. To which organization should he have gone for references?
| Your point is valid. I know of no research organization that would make recommendations. The SPR (Society for Psychical Research) probably wouldn't recommend mediums because the organization has no corporate opinion even if individuals do. Wiseman as a (former) member could have asked off the record for suggestions for trial. But as you rightly point out ....... Quote: |
Surely you agree that if Wiseman had chosen the mediums himself, he would have gotten no end of reaming?
| Yes unless he had chosen some well known ones, I think you are indeed correct Wiseman was always going to get criticized by someone, somewhere  If the trials had been somewhat successful, the debunkers would have turned on him instead

David | From Gary Schwartz: After-death communications: A misleading critique - Follow-Up - response to Wiseman and O'Keeffe, Skeptical Inquirer, November/December 2001 - Brief Article | Skeptical Inquirer | Find Articles at BNET.com
Wiseman and O'Keefe correctly point out that the greater the number of deceased relatives for the mediums to identify, the greater the likelihood of a chance explanation; but that applies equally to the simple-guessing control group. In any case this hypothetical concern can't explain that in Study 1, for example, all five mediums reported a deceased son; three reported the initial M; one the name Michael; three that the death was quick, and two reported or implied suicide by gunshot. Not only were all these answers both correct and ignored by W/O; they equally ignored the converse, i.e., that no medium reported a deceased daughter, or gave an incorrect initial for the son, or a name other than Michael, or suggested a different cause of death.
That is not only seriously misleading, it transgresses the rules of fair criticism that Ray Hyman and others have repeated. An example of selective quotation relates to the "once, twice, thrice" statement concerning the loss of children. Here W/O failed to mention that this medium then referred to a miscarriage which the sitter had kept secret from her husband, as well as the experimenters.
It is not responsible science for W/O to ignore data inconsistent with their criticisms. Skeptics have a duty to practice what they preach: even-handed skepticism. |

'....Berger did an meta-analysis of Blackmore's parapsychological work actually shows a weak effect, so Blackmore then dismissed her own work as inconclusive.' Quote:

What source are you using when you quote this, btw? | | Ersby, you are correct to point out that Blackmore had been critical of her own experiments before Berger. So my wording is perhaps unfair. However the tone of confidence in her experiments does seem to vary or be much lower in response to Berger than say in her statements when speaking to skeptics such as in Blackmore's CSICOP paper called .... 'The Elusive Open Mind: 'Ten Years of Negative Research in Parapsychology'
She didn't call it 'Ten Years of Inconclusive Research in Parapsychology'.
In her response to Berger, Blackmore concludes 'Nevertheless, I am glad to be able to agree with his final conclusion—"that drawing any conclusions, positive or negative, about the reality of psi that are based on the Blackmore psi experiments must be considered unwarranted"
This does not match the confidence placed in her own experiments in the CSICOP paper such as ... 'One should rely only on the statistics, and they were telling me that there was nothing there.'
Or was she was looking for too strong effects in too small samples sizes? Blackmore (apparently) went from a firm believer to disbeliever. Believers and disbelievers tend to share something in common. Most believers think psi is often a strong effect and debunkers tend to believe psi should be a fairly stronger, more consistent effect if real. This is where I very much disagree with the New Agers and die-hard skeptics, I think the brain evolved to filter out psi.
We need to look for weak effects and shouldn't be necessarily viewing psi as a talent to be easily developed or an inherent ability but we also need to consider psi as a potential interference, a breakdown in brain filtering that models our physical reality .....i.e. psi as an evolutionary disadvantage for various reasons.
Blackmore has perhaps missed the connection (due to her past belief in seeking to find strong, stable psi) when she writes 'But human beings are not built to have open minds. If they try to have open minds they experience cognitive dissonance. Leon Festinger (1957) first used this term. He argued that people strive to make their beliefs and actions consistent and when there is inconsistency they experience this unpleasant state of "cognitive dissonance," and they then use lots of ploys to reduce it....'
Perhaps this is exactly what uncontrolled psi becomes, a 'cognitive dissonance', if so is it surprising that the brain may have evolved to largely filter psi out?

| | Dr. Steven Novella on materialism versus dualism: Quote:
If the mind is completely a product of the material function of the brain then:
- There will be no mental phenomena without brain function.
- As brain function is altered, the mind will be altered.
- If the brain is damaged, then mental function will be damaged.
- Brain development will correlate with mental development.
- We will be able to correlate brain activity with mental activity – no matter how we choose to look at it.
All of these predictions have been resolved in favor of materialism. Every single one!
Dualism makes predictions too – that some mental function will be documented to exist separate from brain function. The evidence for this? None.
| Does that clear things up a little? I think that's a succinct slam-dunk of dualism. Perhaps this has already been posted and rebutted? If so, please refer me to the relevant thread.
And please spare me the, "Yeah, but we MIGHT find evidence for dualism one day!" Yeah, and rainbows MIGHT start flying out of ponies' asses.
Oh, but wait! What about Sheldrake's research?! Let's see...ignoring prior probability, cherry-picking positive results that STILL amount to no more than noise, statistically speaking. Is that your only "evidence" for the possibility of dualism?
Which is more likely: telepathic dog-owner relationships, or mistakes on Sheldrake's part? Seriously.
Keep believing all you want, but there's no intellectual dishonesty on the part of Novella or most other scientific skeptics. Most of us would like nothing more than to see legitimate evidence for the paranormal. But we follow the evidence, not romantic idealism.

| Simply not true. Novella is playing numberless dot to dot - how exactly the brain works is not known. He expects to see a materialist paradigm and perhaps like people see faces in wallpaper that aren't there, perhaps what he sees in the data, isn't the correct, whole picture?
Just some problems with physicalists' model of brain creating consciousness..
- No location found for consciousness, nothing like a central processing unit either
- No location of long term memory (although memory is stored/filtered via hippocampus, it is not stored there)
- No location of tacit memory
- No location of freewill choice decisions
- No mechanism known to solve the 'binding problem'
- No reason for unconscious processes to evolve consciousness as a user illusion
- Long term memory survives brain damage and disease better than short term memory
In other words, there is nothing to contradict the concept of an external mind filtered by the brain.

| All one big argument from ignorance. The truth is, the more we learn about the brain (advances are occurring exponentially), the more dualism shrinks as a possibility. The opposite HAS NEVER HAPPENED. With advances in fMRI and whatnot, we have yet to come across an issue that we're technologically capable of exploring where we said, "Wow, that supports dualism!" Quote: |

| | Skidoo,
If a theory is wrong, a lot of the arguments against it will seem like arguments from ignorance. Let me take one interesting example:
In the 1980's and early 1990's the idea that Artificial Intelligence (AI) was not just feasible, but inevitable became popular. This idea was, of course, based directly on the physicalist notion that the brain is doing nothing but a computation, which could be done more efficiently inside a computer.
Unlike Ψ-research, vast sums of money were pumped into AI research over a period of about a decade, and incredibly little has emerged from all that effort. Real AI seems as far away as ever, and most people have just got bored with the idea and moved on.
Paul C. Anagnostopoulos, who takes a physicalist point of view, now estimates that real AI may take 200 years - which gets him nicely off the hook of discussing its failure so far, and the contradictions it seems to generate!
Yes, you can claim that we are simply ignorant of how to write a truly conscious AI program, but how much effort has to go into one approach before you start looking for alternatives?
fMRI techniques are very interesting, but I think it is very important to be clear exactly what they DO and DON'T tell us. While they do indicate areas of the brain that work hardest to process various situations, they actually tell us nothing about how they do that processing. Imagine you could measure the electrical activity in the various parts of a computer while it was performing word processing. Perhaps you could detect the burst of activity associated with each keystroke. Great - but if you knew nothing about computer hardware or software, you could amass that kind of information till the cows came home, and be none the wiser! Whether you are a physicalist, dualist, or (better) an agnostic, it is surely important to recognise that we understand very little about what thought is, or how it is processed - so to argue, as you do, that all the evidence is stacking up on the physicalist side is a bit premature.
It is also wrong, in that there is quite a lot of evidence pointing in another direction, but that evidence - such as Dean Radin's presentiment work - is just ritually dismissed by the more dogmatic materialists. Clearly, one way to 'win' an argument is to simply refuse to look at any evidence that points in another direction, as Lewis Walpert famously did when he turned his back on Rupert Sheldrake's slides of data while debating with him!

Again, none of the hypotheses proceeding from a materialistic view of the mind have ever been falsified. In fact, they have been supported, and as we learn more about the brain, the positive evidence for a materialistic view mounts, while support for the dualist view diminishes. Quote: |

| So what? At present, they tell us how different subsystems of the brain interact to produce various phenomena. Do they show us precisely which individual neuron signaled which other at a given moment? Not yet. But this is irrelevant to the correlations observed between brain activity and mental phenomena. Again, this is an argument from ignorance. Quote: |

Great - but if you knew nothing about computer hardware or software, you could amass that kind of information till the cows came home, and be none the wiser!
| This makes no sense. I could test many important hypotheses about the computer's functioning, even if I could only monitor electrical activity, and didn't know all of the details of its internal functions. To use your example, I could observe that new words never appear in the WP program unless the keyboard is activated. Further experiments would demonstrate that destroying the keyboard will prevent future words from ever showing up in the WP program's window.
In fact, I could make the previous observations without even having any knowledge of the electrical activity! This would be tantamount to observations made after invasive brain surgery or traumatic brain injury. Which is almost certainly what prompted Hippocrates to write the following in the third century B.C.: Men ought to know that from nothing else but the brain come joys, delights, laughter and sports, and sorrows, griefs, despondency, and lamentations.

| "A bit premature?" The materialist view begets many testable hypotheses, all of which have repeatedly been supported, none of which have been falsified. The ever-mounting body of evidence supporting a materialist view of the mind is huge. There is no evidence supporting dualism. Quote: |

For some amusing reading, I suggest instead this paper by Radin: Effects of Intentionally Enhanced Chocolate on Mood. Quote: |
