That makes me sad. But it’s true. I didn’t realize this until I watched this recorded panel from earlier this year. You can hear him admit it around 24:00.
He explains that his reasoning is laid out in the piece “Heads I win, Tales you Lose” published in Skeptical Inquirer in 2010.
After more than sixty years of experimentation, researchers have failed to reach a consensus about the existence of psi (psychic ability). Some argue that there exists overwhelming evidence either for or against the psi hypothesis, while others believe that it simply isn’t possible to answer the question one way or the other. One of the main obstacles to closure on the psi question involves the way in which null results are viewed (Alcock 2003). Many parapsychologists have adopted a “heads I win, tails you lose” approach to their work, viewing positive results as supportive of the psi hypothesis while ensuring that null results do not count as evidence against it.
While I haven’t worked directly in the field and published many papers like he has, I can certainly see his point. I’ve not been impressed by the methods of psi researchers and said so.
In this talk, he talks about the field of parapsychology and its future — that it’s a complete waste of time, a true pseudoscience. If after 70 years, there is nothing to go on, it’s time to move on. (Note how this can be applied to UFOs, Bigfoot, ghostly encounters, as well.) So, you can’t very well blame him for no longer pursuing a lost cause. (I often feel this way myself about the skeptical community.)
I find myself often referencing Wiseman’s works because they cover exactly what I need to be addressed and they are readable. He’s been a great teacher for me. He’s now moved totally into the realm of self help ideas and the concept of luck. Also good but not the anomalistic psychology I am fascinated by. Oh well, we all move on.
If you go to his website now, you’ll notice that parapsychology themes are second to more conventional (but still SKEPTICAL) topics like sleep and dreams, luck, and perception (mainly the quirkiness of our perception and how we can be fooled). That should not stop you from picking up this excellent book: Paranormality: Why we see what isn’t there by Richard Wiseman
