In my opinion, it is certainly a contributing factor to both his claims of success (in, for instance, the staring studies and the "dogs who know when their owners are coming home" studies), and to the quick dismissal of his findings by mainstream researchers.Shera said:I'm also wondering, in his more recent books and also on his website (www.sheldrake.org) he is strongly encouraging laypeople to get directly involved with scientific research. Could this be a contributing factor to other scientists ignoring him?
One of the more amusing findings in parapsychology is the "shyness effect", which basically states that psi effects are "shy", and that as you increase experimental controls, they hide. Of course, the other thing that decreases as you increase experimental controls...is error. Sheldrake's eagerness to include laypeople is both brilliant (mostly from a PR standpoint) and foolhardy; the concepts of "double-blind", "random assignment to conditions", "randomization of stimulus events", among others, are not immediately understood and appreciated, and yet are absolutely crucial if we are going to trust our results. In the staring experiments, for instance, I would argue that laypeople would be far more likely to be lax about conditions (thus considerable variability in terms of sensory leakage may be introduced), and far more succeptible to motivated reporting of results (much more inclined to report their results to Sheldrake if they find positive results than if they find nothing). Those would be two systematic sources of error; there could be others, of course. Sheldrake (if you saw his "7 experiments" video) appears to simply pile all the experimental results together, resulting (inappropriately) in a huge sample size, which (because statistics are sensitive to sample size) in a very low probability (or high significance) result.
Anyway...this is already longer than I have time for this morning...Bottom line, Sheldrake is ignore by maintream science because of methodological issues (although he does respond to criticism and adjust his methodology in response, to give credit where it is due), and because his morphic field explanation is so vastly different from, and less parsimonious than, our current understanding of visual perception.
