190 is a very small number (there's a larger petition indicating "dissent
from Darwinism", and then an even larger petition against that petition
composed only of biologists named "Steve"[1]), and the opinions of scientists
are irrelevant anyway. What matters is what their research shows.
I note that the petition you linked to has "scientists" of all kinds
including, for example: "Vânia Araújo Condessa, MSc., Electrical Engineer,
Belo Horizonte, Brazil", "Prof. Klaus-Peter Ossenkopp, Ph.D., Department of
Psychology (Neuroscience), University of Western Ontario, Canada", and "Prof.
Girish Kumar, Ph.D., Electrical Engineering Department, Indian Institute of
Technology, Bombay, India", among many others. I don't see why I should trust
what an electrical engineer or psychologist to understand electromagnetic
radiation.
It's also regrettable that the petition claims: Numerous recent scientific
publications have shown that EMF affects living organisms at levels well
below most international and national guidelines," and yet fails to reference
a single one of these "numerous recent scientific publications". Perhaps you
are familiar with them?
I would split it off into the Troll Lounge, but the topic of this discussion
should be a scientific paper or a collection thereof and a discussion around
what that research means. This is impossible at this moment because I'm still
not aware of any such research. I certainly encourage you to start the new
thread with a link to that paper, though, or otherwise I would be happy to
start the thread once I know what study or studies we're talking about.
