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)
“You have waited, you always wait, you dumb, beautiful ministers,
We receive you with free sense at last, and are insatiate
hence-forward,
Not you any more shall be able to foil us, or withhold yourselves
from us,
We use you, and do not cast you aside—we plant you permanently within us,
We fathom you not—we love you—there is perfection in you also,
You furnish your parts, toward eternity,
Great or small, you furnish your parts toward the soul.”
—Walt Whitman (1819–1892)
“Every one knows about the young man who falls in love with the chorus-girl because she can kick his hat off, and his sister’s friends can’t or won’t. But the youth who marries her, expecting that all her departures from convention will be as agile or as delightful to him as that, is still the classic example of folly.”
—Katharine Fullerton Gerould (1879–1944)
