The Man Who Was Allergic to Radio Waves

"A review published last year in the journal Bioelectromagnetics found no evidence that hypersensitive individuals had an improved ability to detect EMFs, and the study found evidence of the nocebo effect in those same people."

Every time I see someone claiming to have extremely clear symptoms of EMFs sensitivy, I wonder why they don't do a double-blind test to prove the whole world they can actually detect radio-waves. Should be a trivial test to perform properly, and would clearly help the case of hypersensitive people, so why hasn't it happened yet?
