the subject was lying on the wellness tests. They dropped it probably
to avoid correlating wellness scores with nervousness. If I were
doing it, I would probably dump the LCD touch screen, and run the test
orally, so I could use a voice stress analyzer.

tests always are in a rush (to get out of there). If the list is
presented on paper, one typically starts at the top, checks off a few
items, and then thinks "that's enough". If the list is presented on
an LCD screen, one at a time, where one is asked "Yes/No" to each of
the symptoms, the opposite happens. Near the end of the list, people
tend to feel guilty pushing no all the time, and throw in a few yes
answers for balance. Somewhere in my pile of papers is a study done
on such "check all that apply" lists, which demonstrates the effect.
Oddly, the most common real RF complaint I can recall is hearing tones
or noises. That makes some sense with the 217Hz GSM pulse rate. I've
seen ear rings respond to this. Also, an aluminum coated fire
fighters jacket. It's subtle, it's real, but it's not on the list.
What I think would have made more sense is to ask the participant
"What do they feel different from when they entered the room" and have
the researchers tabulate the results in general catagories.
any of the participants brought their own cell phones. It wasn't
mentioned in the test procedure. Table 6.1 shows the order of
frequency testing, which looks symmetrical in both time and block
order. Therefore, I don't think there would be a time effect (i.e.
we're late and I want to get out of here). Perhaps the Agilent RF
generator made different noises on 2100 MHz just outside the room. I
can't think of anything better.

Good idea. Thanks.
That's what I was mumbling about. What it seems to say is that there
was absolutely no exposure data from Group B (non-complainers) with
GSM at either 900 or 1800. There was some data at 2100. Therefore,
since nobody in Group B felt anything, they'll just generate some
numbers based on the relative level of complaints between the two
groups. It's a little better than fabricating data, but not by much.

Ok, that makes sense. Still, it's kinda dumb stuffing the probe
directly in front of the antennas, which is guaranteed to produce
weird measurements, affect the antenna patterns, and affect the
exposure levels.
If they had recorded those two, I could get a minimal indication if
the subject was lying on the wellness tests. They dropped it probably
to avoid correlating wellness scores with nervousness. If I were
doing it, I would probably dump the LCD touch screen, and run the test
orally, so I could use a voice stress analyzer.

I suffer from all the above even without RF exposure.
There's another problem. The list is too long. People taking such
tests always are in a rush (to get out of there). If the list is
presented on paper, one typically starts at the top, checks off a few
items, and then thinks "that's enough". If the list is presented on
an LCD screen, one at a time, where one is asked "Yes/No" to each of

No difference, unless there are some resonance effects. I wonder if
any of the participants brought their own cell phones. It wasn't
mentioned in the test procedure. Table 6.1 shows the order of
frequency testing, which looks symmetrical in both time and block
order. Therefore, I don't think there would be a time effect (i.e.
