The author common to both studies (Roe) changed their mind in light of improved experiment. Only a fool would do otherwise.
Are we basing scientific conclusions on opinions and personal positions now?...

As I've explained before to you, I don't recognise this profound distinction you do between the "physical" and the "non-physical".
And that is your choice, but words and concepts don't just disappear if you close your eyes tightly enough.
Nicko wrote:If morphic resonance were an actual thing, then what we would be dealing with would be some force or substance hitherto unaccounted for by the body of scientific knowledge. "Physical" and "Non-Physical" don't enter into it.
If it's non-physical then, by science's very nature, it will always be unaccounted for even if real.
Nicko wrote:As I've also explained to you before, this would merely place us in the same position as we were before scientists started studying gravity, or air, or any number of extant things that are not directly observable in an obvious way. That is, Sheldrake thinks phenomena (the bit I bolded in your post) are being caused by this force or substance,he forms falsifiable hypotheses about how this is happening, he attempts to falsify them, he adjusts his hypothesis and ... surely I don't need to tell you how this works?
It wouldn't be the same as things like gravity, air, etc, are physical things and science can study the physical things (as I've explained to you before).

do understand you are
not supporting Sheldrake's attempt to lower the standards of the scientific method due to the fact that this would obviously destroy the confidence in results that is what makes science useful in the first place. I just think you are giving the guy's claims unnecessary credence.
I'm not giving them any credence at all, I am simply respecting the scientific method and not trying to abuse it in order to fit my personal beliefs. I would
love for science to be able to state that non-physical or supernatural things don't exist. I would be ecstatic if I could devise such experiments, publish them, and state with a high degree of certainty that the ideas expressed by anti-science idiots are objectively wrong.
I just can't do that without fucking up the process of science.
Nicko wrote:What we are dealing with is a dude who was quite willing to use the scientific method, right up to the point that he was unable to provide the evidence required to back up his hypothesis and who has gone on to blame the scientific method rather than the failings of either his methodology or his hypothesis.
It's absolutely
classic pseudoscience.
Maybe so but I find it troubling that so far nobody has actually explained
why his arguments for a change in the scientific method are wrong. Remember that what you've described there has occurred multiple times in the history of science and their arguments were found to be accurate, and we actually changed the scientific process in light of them. So whilst it may be an act of pseudoscience, it could also be a necessary reaction to a flaw in scientific methodology.
I don't believe it is but I think people seem to be dismissing it without reason and instead basing their position on what is essentially: "But science is right!". Yeah, often it is right but sometimes it's inadequate and needs to be fixed - the debate here is whether this is an instance of science being right and a charlatan refusing to admit fault, or whether it is something that needs to be fixed.
Pebble wrote:Firstly, the discussion of "shortcomings" doesn't mean the study was flawed, it means that it might not have been as rigorous as it could have been. If we interpreted "shortcomings" as "flawed" then, by definition, practically every single scientific study would be "flawed". And obviously we can't judge whether the authors' claims of shortcomings are valid or not without access to the paper and I can't find it.
Secondly, that doesn't contradict the comment of mine that you linked. The discussion there was about whether "failure to replicate" indicates that there was no effect or not. Newolder argued that it does and I argued that it didn't, but there was no discussion about shortcomings in methodology.
True and untrue. In general 'pilot' studies tend to produce 'large' effects due to faulty design and type 2 errors among other things. Often subsequent studies being better designed end up with much narrower confidence intervals, which often can exclude any significant effect.
Now that is an ideal scenario - but take for example initial studies suggesting magnesium, vitamin E and HRT were beneficial in heart disease, followed by properly constructed trials showing no benefit and even a trend to harm. The authors of int initial 'wrong' trials were the most resistant to this new information.
Usually however, while further trials may be negative, they lack to power to exclude an effect.
Sure, no disagreement there, but we aren't talking about pilot studies. And whilst we'd
assume that follow-up studies are better designed, this isn't necessarily true so if the only information we have is that there is one positive result and one negative, we have no way of deciding between the two.
