It all started with the Voice. A long time ago. I think it was the 70's. Faye Dunaway was all the rage.
"THE IDEA OF A GROUP OF PEOPLE CONVINCED THEY ARE TARGETED BY WEAPONS that can invade their minds has become a cultural joke, shorthanded by the image of solitary lunatics wearing tinfoil hats to deflect invisible mind beams. “Tinfoil hat,” says Wikipedia, has become “a popular stereotype and term of derision; the phrase serves as a byword for paranoia and is associated with conspiracy theorists.”
"In 2005, a group of MIT students conducted a formal study using aluminum foil and radio signals. Their surprising finding: Tinfoil hats may actually amplify radio frequency signals. Of course, the tech students meant the study as a joke."
I don't see how any of this is as a joke. Tinfoil was thought at the time to provide some protection for Targeted individuals. If I was The Drug Nazi or Steve Nash's Wife I would definitely consider owning a bit of foil or never leaving the house. You don't have to be Tom Cruise to see that much of Psychology is bunk and the government is out to get us.
