Un article fort intéressant de Richard Wiseman commentant l'expérience "dog that knows that their owners are coming home" de Ruppert Shelrake et pourquoi il ne considère pas que celle-ci permette de conclure au fait que le chien (nommé Jaytee) est medium.

How much is that doggy in the window?
A brief evaluation of the Jaytee experiments

Conclusion:

I do not find the two studies compelling evidence of psychic ability as each allow for a normal explanation.

- There are several discrepancies between the way in which the data has been presented in two different sources.
- The results of the ‘ordinary’ homecoming trials could simply be due to PS (or her parents) inadvertently communicating her likely return time to Jaytee.
- The results of the ‘random’ homecoming trials could be due to Jaytee visiting the window more frequently over time. Indeed, such switching behaviour makes sense given the very different circumstances of the study. Imagine wanting to be in hall to greet your partner on their arrival home. If you knew the time that they would arrive you would simply go to the hall at the correct time. If, however, you were uncertain when they would arrive, you might become more anxious as times goes by and therefore visit the hall more frequently. Of course, it could be argued that Jaytee would not have the ability to detect and utilise inadvertent cues from PS and her parents, or be able to adapt his behaviour to suit the experimental context. However, one would then have to argue that such abilities are less plausible than him possessing psychic powers. The only way of resolving the issue would be to carry out an experiment that eliminates both the notion of an owner inadvertently communicating their return time to their pet, and the pet signalling their return more frequently over time. Unfortunately,
the existing studies with Jaytee do not fulfil these criteria.
