Persinger has published a reply to a critical article in a British “pop” psychology magazine (The Psychologist) entitled “Neuroscience for the Soul”. This article perpetuates a few mistaken notions about the God Helmet, as well as some of Persinger’s theories.
For example, Persinger does not believe that spiritual and religious experiences are seizural events in the temporal lobes, and he also rejects the idea that religious belief is an epileptic phenomena.
Richard Dawkins, the flagship author and semi-official spokesman for the skeptical movement, had been drinking before his God Helmet Session, and that’s why he felt so few effects.
The low-intensity magnetic fields used with the God Helmet are strong enough to create striking effects, and this link will take you to a page where you can see that lots of other researchers have seen measurable effects using low-powered magnetic fields on the brain.
Skeptics insist that Persinger’s work with paranormal phenomena (correlating it with geomagnetic measures) has not been replicated. However, it simply isn’t true.
In spite of claims to the contrary, there has been a replication of a God Helmet experiment, as well as replication of other work by M.A. Persinger.
The “Haunted Room” experiment (intended to try to create a synthetic haunted environment) was not a test of any of Persinger’s concepts, in spite of claims to the contrary. The “haunted room” experiment used whole-body stimulation (to try to create an artificial “haunted Room”), while Persinger’s experiments stimulated only the head, and sometimes just one side of it. You can’t stimulate only the right side of the head using an entire room as the stimulator.
Most of the criticisms of Persinger’s theories and ideas resolve into “straw man” arguments. These are arguments that give the impression of criticizing a person’s argument, while actually challenging a position that they never advanced. It creates the illusion of having falsified an opponent’s proposition by covertly replacing it with a different proposition (i.e. “stand up a straw man”) and then to dispute the false argument (“knock down a straw man”) instead of the original proposition. Other straw man arguments are based on substituting a critic’s interpretation of a belief for the belief itself.
There are many other points discussed in Persinger’s published reply, making it worth reading for anyone interested in neurotheology and the many debates that have appeared over the years. You can read it here.
