So the question here would be, does this sound relevant to help us understand the paranormal?
Well, there
IS this to be considered:
The researchers then gave the volunteers a drug called L-dopa, which is usually used to relieve
the symptoms of Parkinson's disease by increasing levels of dopamine in the brain.
Both groups made more mistakes under the influence of the drug, but the sceptics became more likely to interpret scrambled words or faces
as the real thing.
40 individuals is a small sample. And they
were separated into 'believer' and 'sceptic' groupings, which in itself introduces 'self
fulfilling prophecy'. Bit difficult for a self-described sceptic to suddenly step 'out of character' during the experiment. They had their pride
and previously-announced convictions (scepticism) to uphold.
Similarly, the 'believer' group would also have wished, consciously or otherwise, to live up to their 'believer' mantle.
So there were two groups of 20, each group virtually committed to confirming their previously-announced beliefs, re: the paranormal. Not much of
value could come from an experiment of the nature described in the OP. Can see it now: the 'believers' desperately 'finding faces' at all costs
and the 'sceptics' dismissing anything with any resemblance to a face (even if it was staring them in the face) as a matter of principle, lol.
The L-dopa element is interesting though, don't you think?
It didn't alter the 'believer' group. Yet it
did alter the perceptions of the staunch 'non believers'. So, interesting in more
ways than one.
Interesting too that researcher Peter Krummenacher theorised (stated as his opinion):
could mean that there is a plateau effect for them
(the believers) with more dopamine having relatively little effect above a certain threshold
Unsaid, of course, is the fact the experiment may have
unintentionally confirmed that the believers have been 'seeing true' all along
and
when the non-believers were administered L-dopa ----
they were able to 'see true' as well !
For the experiment showed that the
believers remained
consistent both before and after the L-dopa !
In other words, the 'believers' are clearly
more stable and to-be-relied upon than the non-believers !
The 'believers' were
UN-affected by the drug.
Instead of acknowledging this however, the researchers
chose to interpret the findings in a way that
minimised and dismissed this
revelation, by stating that
'belief in the paranormal may depend completely on your brain chemistry'.
Which conflicts with the researchers' own findings !!!!!!
Because the 'believer' group was
NOT affected by the brain-chemistry modifying L-dopa ! The 'believer' group remained
constant.
It was the
sceptics who flip-flopped -- who see-sawed, after L-dopa ! It was the brain chemistry of the
sceptics which altered ---
turning them, in effect, into members of the 'believer' group !
From the way in which the results of the experiments were portrayed BY the researchers --- no prizes for guessing the slant of
their
bias !
Now --- where are the scientists who'll conduct research into paranormal
experience, rather than mere 'belief in the paranormal' ?
There are a hell of a lot of experiencers out there, just waiting for the call.
