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:
“The knocking out of a pipe can be made almost as important as the smoking of it, especially if there are nervous people in the room. A good, smart knock of a pipe against a tin wastebasket and you will have a neurasthenic out of his chair and into the window sash in no time.”
—Robert Benchley (1889–1945)
“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)
““If the law supposes that,” said Mr. Bumble, squeezing his hat emphatically in both hands, “the law is a ass—a idiot. If that’s the eye of the law, the law is a bachelor; and the worst I wish the law is, that his eye may be opened by experience—by experience.””
—Charles Dickens (1812–1870)
