<<
In the trial, many of those who blame masts for their symptoms reported
greater distress when they thought the signal was on, suggesting the
problem has a psychological basis.

What they are not telling you in the above is that many health problems
have a psychological *component*. There is no way of telling from their
experiment whether symptoms were entirely psychologically derived or
whether it was a psychological component (which is not unsurprising as the
symptoms were subjective rather than objectively measured).

<<
However, when tests were carried out in which neither the experimenter or
participant knew if the mast was on or off, the number of symptoms
reported was not related to whether a signal was being emitted or not.

Symptoms like "anxiety, nausea and tiredness" don't switch on and off
in time with a signal. If a stimulant triggers an anxiety attack then I'm
afraid the sufferer is going to have to ride it out for several hours.
Once tired that symptom isn't going to go away in on/off fashion either.

The study doesn't prove that sufferers symtoms are always psychological,
they only show (perhaps) that people suffering with real symptoms may have
their symptoms and suffering re-triggered or induced by psychological
means which of itself is not surprising at all.

The whole study was a pointless waste of time and money in my view. Think
of all the objective studies done so far that do show biologic effects,
that's the way to study the problem. Not playing silly mind games with
people who are already suffering health problems.
