In 1995, Rupert Sheldrake began an investigation of a dog named JayTee and his apparent ability to know when his owner, Pamela Smart, was on the way home. Dr. Sheldrake became aware of JayTee when Smart answered an advertisement in the paper looking for dogs who seemed to know when their owner was returning home.
Dr. Sheldrake began to observe JayTee and it quickly became apparent that JayTee was, indeed, going to the window and apparently waiting for her whenever Smart was on her way home. And this behavior occurred despite changes in her return time and using a variety of different modes of transportation. So Sheldrake designed a videotape experiment to provide objective evidence of JayTee's unusual ability, and conducted a large number of trials with Pam and Jaytee.
Sheldrake invited Dr. Richard Wiseman to perform his own videotaped trials with Jaytee. Wiseman conducted four trials total and then proclaimed loudly to the media that JayTee had no special abilities.
However, Sheldrake obtained the videotape data and found that Wiseman's data matched his own experimental data very closely.
It appears that Dr. Wiseman is still claiming JayTee showed no special abilities and "failed the test" despite the fact that his own data matches Sheldrake's. Certainly most of the "skeptic" websites seem to loudly proclaim how Wiseman "disproved" Sheldrake's research with JayTee.
I'm including data published in Sheldrake's account of the controversy with Wiseman below so you can judge for yourself.
The first graph shows Sheldrake's data from 30 videotaped trials. The second shows data from Wiseman's 3 trials taken at the same location. The bottom graph shows control data from 10 trials when Smart arrived home much later than the recorded data or did not return that evening. Note that the last point in all trials shows the first 10 minutes of Smart's return journey which always lasted at least 13 minutes, so no data from Pam's actual arrival in the vicinity.
UPDATE: Richard Wiseman admitted in his recent Skeptiko interview, that his data does correspond with Sheldrake's. Wiseman should be congratulated for his honesty about this.
