A tin foil hat is a piece of headgear made from one or more sheets of aluminium foil or similar material. Alternatively it may be a conventional hat lined with foil. One may wear the hat in the belief that it shields the brain from electromagnetic fields; to prevent mind control and/or mind reading; or to limit the transmission of voices directly into the brain.
The concept of wearing a tin foil hat for protection from such threats has become a popular stereotype and term of derision; the phrase serves as a byword for paranoia and persecutory delusions, and is associated with conspiracy theorists.
This stereotype is popular in pop culture, with tin foil hats making appearances in movies such as Signs and Futurama: Into the Wild Green Yonder.

“Like bright metal on a sullen ground,
My reformation, glitt’ring o’er my fault,
Shall show more goodly and attract more eyes
Than that which hath no foil to set it off.”
