personally, i don't think investigations are ridiculous. After all, science at its most basic function asks a question and then tries to find an answer using observation and empirical evidence.
I understand your position about magnetism as an investigative technique, but I would not discredit an entire group of investigators, which include many serious folks concentrating on the science of the paranormal; trying to gather empirical evidence that will disprove or support their conclusions.
