Have Radionic Instruments Been Scientifically Validated?

This depends on what we mean by 'scientific validation'. If what we mean is whether radionic instruments have been tested and found to obey the laws of physics or that of material science, our answer is 'No'. The framework of material science and that of radionics are different, so it is difficult to use one to evaluate or validate the other.
Radionic instruments are physical structures no doubt, but what they are used to accomplish cannot be tied to their engineering designs.

All radionic practitioners know that their instruments serve only as extensions of their diagnostic (not in the orthodox sense) and healing faculties. On their own, the instruments do absolutely nothing. Now, this bring up the question: why do some practitioners shell out a lot of money for very expensive instruments, some with outrageous claims that boggle the mind? This is where choice comes in. It might well be that such practitioners build thoughtforms of greater efficacy around such instruments and they might well have better results due to this. But we have seen practitioners who merely made line drawings of their instruments on paper an accomplish wonderful results. We do not believe that the cost or the complexity of the instruments have anything to do with the therapeutic results obtained since radionics works on the realm of thought.

Having said this, we must make an honorable exeption to orgone devices since these ones are not actually radionic instruments, but they do enhance or potentize radionic treatment. They operate on laws and dimensions peculiar to themselves.
