Not Persinger again!
Yes, he is still researching, if you can call it that. Persinger is
convinced that UFOs, ghosts, paranormal experiences, religious
hysteria, mysticism and most other borderline phenomena can be linked
to the effects of electromagnetic radiation on the temporal lobe.
Unfortunately, while he produces very nice correlations and p-values,
his methodology seems somewhat flawed. In one study, he used a listing
of UFO cases to show a connection to earthquakes more than 500 km away
from the sighting locations. When it was pointed out that most of the
UFO reports were merely airplanes and stars, he brushed the criticism
aside by saying that the 95% IFO "noise" wouldn't obscure the "real"
Persinger has published over 100 articles in generally scientific
journals, but has been largely ignored by his colleagues because of his
maverick studies which encompass geophysics, neurophysiology and
Basically, he has an interesting theory, but it is not rigourously
supported by other studies. It SOUNDS like good science, but something
went awry somewhere. His original doctoral advisor thinks he is
reading far too much into his data these days, too.
When Persinger's research was brought up in this newsgroup a year or
two ago, I was asked to post a list of published criticisms of his
theory. He never seems to mention any of these anymore. Here's a
report of the list:

Another book by Persinger, TM and CULT ANALYSIS, was very unfavourably
reviewed in CONTEMPORARY PSYCHOLOGY, 26 (5), 1981, being called
"appaling", "pseudoscientific" and "misleading". The title of the
review was "Fundamentals of Nonobjective Analysis"!
