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.

Famous quotes containing the words tin, foil and/or hat:
“A ‘spasm band’ is a miscellaneous collection of a soap box, tin cans, pan tops, nails, drumsticks, and little Negro boys. When mixed in the proper proportions this results in the wildest shuffle dancing, accompanied by a bumping rhythm.”
—For the City of New Orleans, U.S. public relief program (1935-1943)
“Learning is, in too many cases, but a foil to common sense; a substitute for true knowledge. Books are less often made use of as “spectacles” to look at nature with, than as blinds to keep out its strong light and shifting scenery from weak eyes and indolent dispositions.... The learned are mere literary drudges.”
—William Hazlitt (1778–1830)
“The doctor of Geneva stamped the sand
That lay impounding the Pacific swell,
Patted his stove-pipe hat and tugged his shawl.”
—Wallace Stevens (1879–1955)
