Dear
Pehr,
We were disappointed by your email that
requests we have no further collegial interaction. I am confident
that both of our teams, working in concert, could solve the problem.
This is of course your choice. We will respect your request. We
would have preferred cooperation. However I will answer this email
because it is difficult to assume your colleagues would agree
with the tenor of your manner in this and previous correspondence.
Your email was replete with errors and
misstatements that might be consider libel by some readers. I
would prefer to think the difficulty is with communication between
speakers of different languages rather than a purposeful rudeness
in your style or deviance in your motive. However it appears you
misrepresented your purpose from the beginning. We lent you the
equipment because you were supposed to complete a PET study. The
primary discussion with Larsson and Larhammar involved discerning
the effects of these fields upon PET profiles. You did NOT replicate
our procedures.
Your practise of evasiveness in answering
simple questions and responding with accusations or oblique comments
is concerning. In my email to you I asked you about your quote
in the article in the Economist "that the participants (in the
Laurentian studies) were frequently given an inkling of what was
happening by being asked to fill out questionnaires designed to
test their suggestibility to paranormal experiences before the
trials were conducted". This of course is nonsense; we never did
that and you know it.
When I e-mailed you about this you said
it was a misquote and referred to some other issue. However in
your taped conversation to the writer of the Economist article
you stated "the subjects (my subjects) are given questionnaires
to complete before they are tested and these questions refer to
odd or anomalous mental experiences. So presumably these questions
actually act as a prime so the participants are offered a cue
to what type of experiences they're expected to have". How do
you explain the discrepancy between what you emailed me you said
and your taped comments?
Contrary to your statements in your email
there are no distortions or selective quotations from e-mails
in our WEB page. We will be posting the recent corresponsence
as well. I find your statement professionally offensive and personally
disappointing. In actual fact:
1. When the group did visit on 2-3 November,
2000, they were not given a thorough demonstration of the procedure.
(You did not visit our laboratory.) There was not even a hint
you planned to replicate our procedure. The point of our demonstration
was to familiarize Marcus and Dan with the equipment for a PET
study. Common sense in experimental design indicates that measurements
must be taken before and after each subject. If you did not verify
the field than you don't have a clue what was happening. A double
blind with no effective stimulus yields exactly what you obtained:
no effect. During the last 30 years of research I have never encountered
an experimental psychologist who, upon receiving equipment or
procedures, did not complete a pilot study. Again, contrary to
your comment, we have included in our publications that measurements
were taken before and after each subject and that both experimenters
and subjects were blind to the hypotheses. You continue to ignore
and misrepresent these facts.
2. The software for Complex 1.15 was designed
for XTs and related computers, not Pentiums. Our specific parameters
assumed you would have at least verified the fidelity of the field
in terms of its temporal structure and timing.
3. You have clearly misconstrued the intent
of my suggestion about geomagnetic activity and your data. This
would not be "post hoc measurements of geomagnetic fields in your
psychology buildings". The correlations would be between global
geomagnetic indices and the reported incidence of sensed presences.
The double blind argument is irrelevant. A statistically significant
correlation between daily aa (average antipodal) activity appropriate
3-hr k-values and the ratings of sensed presence in your study
would have at least allowed us to discern if indeed what your
subjects were calling "a presence" was similar to what our subjects
were calling "a presence."
.
4. We have not made repeated claims that
we provided you with a device not intended to induce a sensed
presence. What I have said is the parameters we suggested were
intended for you to start with your PET study because that is
what Marcus stated you were going to do. It is apparent that the
equipment lent to you was not the helmet but our first attempts,
as we stated, at miniaturizing the equipment. Again a simple pilot
study would have been appropriate.
5. For your information the dimensions
of a chamber that is 2 m-sq, as specified in your article, would
be 1.4 m x 1.4 m. Finally if the critical information is not included
in your article (e.g., the subjects were blindfolded) how is the
reader suppose to know?
I do not wish to be offensive but in my
four decades of research I have never encountered an experimenter
such as you with such a blatant agenda. The understanding of the
brain bases for the sensed presence is more important than the
petty misunderstandings between people in laboratories. The future
of the human species may be involved. We have more sophisticated
equipment and software. If the Uppsala-Lund research team are
interested we would be most happy to send them the equipment and
specific details at no expense.
Sincerely,
Michael

Dear Michael,
We strongly believe that it is more appropriate to continue with
this debate in
peer reviewed journals, such as Neuroscience Letters, where it
is customary for
scientific debates to take place. That way, our correspondences
will be made
public without any distortions or selective quotations from e-mails,
as is now
the case on your webpage, where you only cite one of our letters
to you.
However, let us still address the queries of yours that we have
not responded to
as of yet. The Christmas break prevented that.
First, in response to your webpage rebuttal, the isolation chamber
was about 2
square meters, as can be read in our paper, not 1.4 meters as
claimed on your
webpage. Second, we used blindfolds, and regret that we failed
to inform
readers of this in the paper. This means that participants were
in complete
sensory deprivation during the session. Also, during our visit
to your lab in
2000, we were given a thorough demonstration of your procedure.
We never
noticed you measuring field presence pre- or post exposure. Nor
have we been
given a priori instructions from you on this matter. Most important,
though,
the procedure is not reflected in your published writings. However,
we have had
the equipment checked for magnetic field generation pre and post
study, with
satisfactory results (see our article for details).
Second, you asked about the instructions to the EXIT scale. The
instructions
were literally translated to Swedish from the form provided by
you at our visit
in 2000. In Swedish, they read as follows:
“Medan du satt på stolen och hade ögonbilden på gavs några stimuli.
För att
avgöra om du märkte dem ber vi dig markera förekomsten av upplevelser
under
experimentet genom att skriva in lämpligt svarsalternativ. Använd
följande
skala: 0 = aldrig; 1 = enstaka gånger (eller åtminstone en gång);
2 = ofta”
Third, you have also asked repeatedly about the calibration and
number of cycles
given. The calibration was done in accordance with the instruction
manual of
Complex v. 1.15. The diode indicators on the DAC indicated timing
in the
correct interval. The total number of cycles was set to 9000 (as
instructed by
you). Exposure time was chosen from your recommendation. Time
was measured with
a digital watch. After 15 minutes the program was halted by using
control-alt-delete, again according to your instruction. In the
event that you
have forgotten these instructions, we attach them to this letter.
Fourth, as for allocating the source of discrepancy in results
between our
research teams, a post-hoc assessment of geomagnetic field variations
in the
psychology buildings is not attainable. Even if it were attainable,
it would at
best give us a crude estimate of the discrepancies, as there was
an important
experimental design difference between our studies (i.e., ours
was truly double
blind, as this term is conventionally defined, whereas none of
yours were).
Also, if fluctuating geomagnetic activity was an important issue
to consider,
you should have informed us clearly before the study started.
Finally, we are not appreciative of your repeated claims that
you would have
provided us with a device that was not intended to induce a sensed
presence. It
is clear from your attached correspondence that the device indeed
was supposed
to induce such phenomena.
Sincerely,
The Uppsala-Lund research team.
