Listening back to that Skeptics Guide interview, there's an amazing comment (about 32 min in) by Hyman where he says he regrets people like Martin Gardner and Randi attacking parapsychology without having read what they are critiquing. It's what most of us suspected all along, but here it is from Hyman of all people. As far as I'm aware, that doesn't happen in any other branch of science. Are sceptics of psi emotionally investing so much in their particular world view that they are afraid of the actual data and will openly criticise the field without looking at it? |

When a theory in real science gets ridiculed, it either puts up or shuts up. When the evidence comes in to support it, it becomes the new accepted science. If, on the other hand, the evidence refutes it, it goes away and dies. The difference with pseudoscience (like psi research) is that even when the evidence weighs in against it, it doesn't go away (in a large part due to, in my opinion, people wanting very desperately for it to be true--a desire for evidence of something beyond the physical world to give them hope that it's not all over when they die--the same reason religion persists throughout the ages). I'm sure some people would say that psi research is just now in the "putting up" stage, and I suppose that remains to be seen. If so, Randi could be in trouble. I personally feel, however, that there has been ample research done, and ample time for the evidence to manifest, and it simply hasn't happened because there's nothing there. This is the same reason why you'll find other people who may be less versed in the area dismissing it without looking deeply into it themselves--they feel the work has already been done for them in droves. |

It's obvious that Alex don't have any philosophical background, and it didn't let the other guy (who really knows what he's talking about) talks. It was really annoying, and I didn't enjoy this episode at all because of that. By the way, Alex don't seem to have any statistical background either, because when he talks about parapsychology experiments, he never talks about statistics, which is kind of odd, because statistic interpretation of the data is a very huge part of the debate! |

As for the whole thing about ψ giving hope when we die, this might motivate some, but honestly, people have all sorts of inner motivations which make them favour one scientific theory or field over another. I got interested in the whole question of consciousness because I had a peripheral involvement in the AI fad of the 1980's - I saw how it was supposed to be going to endow computers with human like thought (but better and faster), and I saw how it basically failed. Consciousness as computation was the only materialist theory of consciousness, and it gave no sign of being right. For me consciousness and ψ are very probably intimately connected. Honestly, if you were doing a fairly delicate experiment in physics (say, I don't know your field) would you let a magician who was for some reason opposed to your research test and pronounce on your work? Why should this field be saddled with Randi, while others rely on peer-review! David |

Ridiculed in the same manner that psi receives? Can you give us an example? Also, I doubt that a theoretical physicist would not even read the literature he is criticising. Again, if you have an example... Quote:

Vehemently rejecting all criticism as invalid is not a hallmark of good science (especially when the criticism could be ruled out by performing further experiments with modified design). It's a hallmark of denialism and crankery, and that's how it gets perceived by the scientific/skeptical community. Quote:
In a broader sense, alternative medicine--homeopathy, chiropractic, acupuncture, energy healing, intercessory prayer... Just like with psi research, there are a small number of unreliable studies that show each of these to be efficacious in treating a wide variety of conditions, but the body of work as a whole indicates that none of them actually work beyond a placebo effect. Any new positive study that comes out is generally dismissed by scientists/skeptics before even looking at the specifics, because in the past, every positive study has either had serious methodological flaws or been a deliberate hoax. Further raising the bar for psi research is the fact that we really should have seen better results by now. How many decades have those little symbol cards been around? Has anybody ever been able to consistently guess better than chance under controlled conditions? And why don't casinos hemorrhage money out when they construct their games to only give a small statistical advantage to the house (small enough to easily be cancelled out or overcome by even the tiniest hint of psi in casino-goers on average in the long run)? All of the evidence and common sense points to psi not existing, and all well-documented experiments that contradict this show at best a barely noticeable effect which can generally be explained by artifacts introduced by problems with the experimental design. And then, to top it off, instead of acknowledging the problems and designing new experiments, the response is instead to generally dismiss the criticism and apply all kinds of apologetics in defense of the original flawed studies. Nobody ever said science was quick and easy. Psi research is going to have to make substantial leaps and bounds before it will ever be taken seriously by science (leaps and bounds that will be unattainable if, as the majority of evidence currently suggests, psi doesn't exist). |

But what if someone does not agree with your supposition here? You are saying that if psi exists it ought to be able to be elicited on demand. But many people -- including myself -- feel your position is absolutely absurd. The manifestation of psi could depend upon a huge number of potential factors. Maybe something as highly obscure as whether there is a full moon or not, to more obvious factors such as the subject's psychological and emotional state. If -- as seems extremely likely to me -- a certain psychological and emotional state triggers psi, then the results from parapsychological research are entirely in accordance with what one would expect. You could of course argue that from the scientific perspective parapsychology has not been proved. But the fact that some research is negative gives evidence against it? Not unless we agree with you that if psi exists it ought to be easily elicited on demand. How many non-sKepics would agree with this? I'm betting not many. Throughout history and across all cultures people have experienced phenomena similar to that which parapsychologists investigate. The similarity of the phenomena coupled with the fact that it is universal gives a very good prima facie case that it actually exists. Parapsychologists are the true sceptics in not just accepting the existence of this phenomena, but investigating it to see whether it is true. Given all the evidence, both in the form of personal testimony, and scientific evidence in the form of psi research and parapsychological research, it seems highly implausible to me to maintain that none of this phenomena exists, least of all that it's been shown not to exist! |

Sure, you can make that claim. It may even be true. But if it is, then parapsychological research needs to shift its focus to figuring out what condition X is if they want to start getting more compelling and consistent results that will actually be taken seriously. Postulating the existence of mystery condition X without actually identifying it achieves exactly the opposite result. It comes off as a desperate excuse. |

Many years ago, when I did experiments, I had an experiment that failed sometimes on a very random basis. It turned out that it went wrong when someone turned on some welding gear in another room - the electrical interference messed up the data recording! If a chemical fails to crystallise, chemists sometimes attribute this to the lack of a suitable piece of dust, or try to scratch the side of the vessel to encourage crystals to form! In the early days of transistor research - when fabrication methods were barely up to the job - does anyone believe that every experiment worked! I do wish sceptics would get real about the nature of normal scientific research! In at least some cases, the problem is that they have never done any!
