Gravity wave researchers try to eliminate other sources of vibration, etc etc.

Firstly, you are still stuck with the fact that nobody has any idea what "morphic resonance" is. You can't predict what should or shouldn't follow from "morphic resonance". You can't manipulate it. You can't turn it on or off.

Scientists don't just try to eliminate confounding factors. They test to see whether they have done so. What is so hard about explicitly testing these possible confounding factors? I note that in the 50 experiments where Jaytee is alone without the owner's parents that the "effect" decreases. This suggests that the dog is getting information form the parents. Do a set of experiments with the parents present and a set without them. Is there a statistically significant difference between the two? Is part of the effect coming from an interaction woth the parents? We'll never know unless the experimanets are done.

It was an earlier comment of this sort that made me question your actual experience of science, because most experimenters have an axe to grind of some sort! Sheldrake is no different!

"But everybody else does it" didn't work when you were caught copying in grade one. It doesn't work when politicians are caught taking bribes. It doesn't work when Scientists take their pet ideas far beyond the supporting evidence. Lots of scientists do this but it doesn't make it right. There is also a question of degree here too. There is a huge disparity between the grandiosity of Sheldrake's claims and the paucity of the evidence that he has accumulated.

Look at the field of evolutinary and developmental biology that Sheldrake abandoned 30 odd years ago to pursue his "morphic resonance". Evo-devo has made a huge amount of progress in these decades. What has Sheldrake accomplished?

It is also noteworthy that Sheldrake has effectively abandoned the normal process of peer-review and instead publishes books aimed at the general public and papers in journals where the standard of peer-review is lower.

No! Sheldrake knows more than most how subtle animal behaviour can be, so he sets up an experiment to eliminate the dog's 'normal' ways of knowing to determine if it knows anyway. How does this differ conceptually from a thousand other animal behaviour experiments?

Sheldrake apperas to be very naive about the capabilities of animals. I still find it hard to understand why he prefers animals to have supernatural abilities rather than natural intelligence. Why is one more desirable or probable than the other?

More importantly Sheldrake does not explicitly test to see whether his efforts actually do eliminate the "normal" ways of knowing. Is there a statisically significant difference between the behaviour of the dog with an without the parents present?

Because the various concepts in this area rather blur into one another - morphic resonance, telepathy, precognition, ?, .... Sheldrake is trying to test the idea that the dog can somehow get information out of its owner's brain. Of course, it is hard to rule out simple precognition of the homecoming event, but either represent a form of anomalous awareness.

You simply can't ignore the obvious fact that Sheldrake is trying to confirm "morphic resonance". You can't ignore the context in which these experiments are done.

You write as though Sheldrake invented the idea of dogs knowing when their owners are coming home, much as you did "rainbow farting uniocorns" - this completely misses the point. These phenomena are reported anecdotally - just as meteorite falls used to be reported - it is totally reasonable for him to choose to explore them.

For all we know the information could be conveyed from the owner to the dog via a herd of rainbow farting unicorns. There is no reason to put this explanation lower than "morphic resonance", telepathy or any other poorly defined and untestable supernatural explanations - or any number of natural explanations for that matter.

The only thing that Sheldrake's experiments are capable of conclusing is that it is valid to reject his null hypothesis. The dog's behaviour is not completely random with respect to the homecoming's of the owner. It does not and cannot "prove" any of the other explanations for the behaviour.

Well, I don't think your criticisms relate closely to what is in that paper. How can you raise the important potential issue of car sounds without acknowledging that Sheldrake dealt with that by dropping several minutes of data! The same goes for a number of your other comments. You state potential problems as though Sheldrake had not handled them, leaving it to the reader to check and discover that he explicitly thought of them and worked round them or tested for them.

Sheldrake does not know how far dog's can hear the car coming. He makes assumptions about this rather than testing this possibility. I have already stated that I don't think that this can explain a large part of the Jaytee trials. Why not experimentally determine how far dog's normal senses can operate? At the very least it would tell you how much time you have to exclude to eliminate this possibility. Do you know how far dogs can hear?

I originally read Sheldrake's paper some years ago, and debating with you, I began to doubt if Sheldrake had done as good a job as I remembered. It came as a shock to re-read the paper and remind myself of the truth. My sense is that some orthodox scientists get a red mist in front of their eyes when they read anything ?-related, and they can't evaluate the evidence before their eye's properly. I mean, claim if you wish that Sheldrake simply fabricated his data, but outside of that, he really does seem to have covered most of the viable alternative explanations in that experiment - and he gets a large effect size.

You seem to think that people pick on Sheldrake unfairly. I can guarantee you that I question the methodology and results of other scientists just as carefully. I expect other scientists to do the same to me. I welcome these criticisms. If the going gets tough and my papers are rejected I don't give up or complain that my brilliant work is being censored. I don't write books targetted at lay-audiences and I don't start up my own "peer-reviewed" journal to escape the criticism.

I get the impression that you are defending Sheldrake not because you think that "morphic resonnce" has any credibility but that he is opposed to physicalism/dualism/science. Any enemy of your enemy is a friend. You'll find yourself embracing "intentional chocolate" and other ridiculous nonsense soon.

The large effect size that Sheldrake obtains is simply a result of assuming that the dog's behaviour should be completely random as the null hypothesis. Any sensory leakage that enables the dog to get some information about the owner's homecoming will produce a large effect size.
