Interesting Ian said:
We've been through this evidence issue sooo many times! It has been provided again and again and again to people on here. I'm pretty sure no-one actually checks it out.
Yes, we do.
The most complete resources for experimental evidence suggestive of parapsychological phenomena can be found in several Meta-Analyses. You can find, for example, composite results for 587 studies of consciousness-related anomalies in electronic REG behaviour described in 152 papers (most in peer-reviewed journals) by 68 principle investigators over a 30 year period, in Radin & Nelson, "Evidence for Consciousness-Related Anomalies in Random Physical Systems" Foundations of Physics, Vol 19 No 12, 1989. Utts published a survey of this and related work in Statistical Science in about 1992.
Statistical manipulation of the results of crappy experiments just gives you crappy statistics.
The value of the PEAR meta-analysis paper is that it not only analysed the results of the experiments, it also compared the results to the quality of the experiment.
And what they found is that the statistical significance of the results is inversely proportional to the quality of the experiment.
When you do the experiment properly, the positive results go away.
Am I saying there is overwhelming scientific evidence like someone above claimed I was? No I'm not. The scientific evidence as a whole appears to be highly suggestive (from what I've read), but, from everything I've read, it is conceivable, albeit unlikely, that all the positive results could be due to normal means of one nature or another.
Why on earth would you think this is unlikely?
We know that when we design the experiments to preclude cheating and bias, the effect disappears.
This directly indicates that previous positive results were the result of cheating and bias.
However there is a nagging worry about the capricious nature of psi
For psi to be capricious, it would have to first exist.
and the fact that some researchers tend not to be able to get positive results, where as other researchers regularly do. Thus it is just to say possible to suppose that there is a normal explanation at underlying all positive results, but the data in and of itself is highly suggestive of some effect.
No.
But our acceptance of that data will obviously also be influenced by our suppositions regarding reality. If we think that we have very good reasons to suppose that reality operates in certain ways, which do not allow for the existence of such alleged phenomena, then obviously such a person will need a great deal more evidence than a person who doesn't share their underlying suppositions regarding reality.
Right.
And everything we know about physics, chemistry and biology precludes the sorts of effects that PEAR are studying.
So for them to be right, physics, chemistry and biology would have to be wrong in really major ways.
Only, physics, chemistry and biology
work, very reliably, so we know they're not wrong in really major ways.
I should stress that it is not irrational to demand extraordinary evidence given such suppositions. However, one could of course attack such suppositions which I do consistently.
Heh.
In short I think the reasons for embracing the reality of some paranormal phenomena -- and here I'm thinking about psi -- are overwhelming.
Well, yes, you do think that.
You're wrong.
Not that I'm saying the scientific evidence alone is overwhelming (I lack sufficient knowledge to judge this)
Yes!
See there, Ian, we do have common ground to reach agreement!
but at the very least the scientific evidence appears to be strongly suggestive.
No.
If you actually knew something about science, you would realise that the "evidence" appears to be utterly bogus.
This evidence, in addition to the fact that people have related experiences of a psi nature throughout human history and across all cultures, in addition to the fact that I'm basically convinced that a materialist mechanical view of reality is simply untenable, makes it overwhelmingly likely, in my view, that psi exists.
Yeah, well, you're wrong again.
The so-called evidence has never withstood any proper scrutiny. Not a shred of it has ever survived the light of day.
Note however that I feel that psi is capricious, unpredictable, and the evidence will rarely be of an "in your face" nature.
So what you actually mean is, when we test for it, it isn't there.
So I'm simply not interested in the debunking that Randi and other skeptics get up to since I never believed them in the first place. Look at my sig.
So what you actually mean is, when we test for it, it isn't there, but you're going to go on believing in it anyway because you don't actually care about evidence.
