“Heads I Lose, Tails You Win”,
Or, How Richard Wiseman Nullifies Positive Results, and What to
Do about It: A Response to Wiseman’s (2010) Critique of
Parapsychology
by Chris Carter

INTRODUCTION
Psychologist Richard Wiseman is a well-known British critic of parapsychology, frequently appearing in the British media to “debunk” psychic research. In his recent (January/February 2010) Skeptical Inquirer article “‘Heads I Win, Tails You Lose’: How Parapsychologists Nullify Null Results”, Wiseman argues that parapsychologists have tended to view positive results as supporting the existence of psi, yet have adopted various strategies to ensure that null results do not count as evidence for the non-existence of psi. However, I am going to demonstrate that throughout Wiseman’s career, he has tended to adopt a “heads I win, tails you
lose” approach to parapsychology’s research findings, viewing null results as evidence against the psi hypothesis, while attempting to ensure that positive results do not count as evidence for it.

After reviewing Wiseman's body of work, I have concluded that he has no credibility beyond his position as chief Psi denier.

Yes, but let's go through all the details. Carter's critique is fun to read.

I will read it again, but I don't have time at the moment.
