What is a Tin Foil Hat?
The term tin foil hat is generally used as a derogatory remark toward someone advancing a conspiracy theory or other story that is considered incredible. It appears to have been coined to describe people who claimed UFO sightings or claimed to have been previously abducted by aliens. It was suggested that such a person might wear a tin foil hat in order to keep aliens from intercepting his or her brainwaves. However, there are some people that actually construct tin foil hats, believing they will protect against mind control programs, radio waves, and electromagnetic radiation (EMR). In fact, a type of device made from aluminum or tin foil may help reduce EMR. It isn’t foolproof since hats or other protective gear aren’t solid enough structures. Electromagnetic radiation is also said not to be harmful, despite earlier possible concerns.
