Ive been wearing the aluminum paper liner to a package of corn pops I find that it blocks much psychic communication which makes the user feel like a Z I urge anyone with patterned thoughts to wear a tinfoil hat. My particular issue is a bit like Asimov's character the Mule that is able to use psychic powers to overstimulate a technician to produce valuable technologies. Anyway during the 20th century there were up to 2 million United states schizophrenics I think the effect of the tinfoil hat is beneficial if the wearers believe n the rest of society just says "well, even a placebo makes a difference" |

Hello, I believe I may have found a new, older use of the concept of tin foil hats dating back to 1863, just under half a century older than the oldest reference currently in this article. It is in the book [https://books.google.com.au/books?id=DzUFAAAAQAAJ&pg=PA334&dq=%22foil+helmet%22&hl=en&sa=X&ved=0ahUKEwjv_v3LmaXlAhXBmeYKHTAQCp4Q6AEILjAB#v=onepage&q=%22foil%20helmet%22&f=false "Hedderwick's Miscellany of Instructive and Entertaining Literature"], p.334. The book doesn't discusses tin foil hats in reference to the common stereotypes associated with them today but rather "Building a ferocious monarch". I don't know if this is actually related or just tin foil hats being used in some unrelated way but though it could be useful to mention. Feel free to check out the source and determine whether it should be added to the article or just ignored.[[User:Resolving|Resolving]] ([[User talk:Resolving|talk]]) 07:28, 18 October 2019 (UTC) |

== Another early reference to the shielding aspect... == |

I don't like the implication that being concerned about Echelon automatically labels someone as stereotypically paranoid. I have no trouble with the idea that paranoid people are stereotypically concerned about being watched (e.g. the TV is looking back at them), I just don't like this example. I haven't changed the article as I thought I'd see if anyone agrees first. - S |
|||
Specifically https://en.wikipedia.org/wiki/Slave_Ship_(Pohl_novel) where toward the end of the novel, telepaths (including the protagonist) must use close-fitting tin-foil hats (not the "dunce cone" type shown in this article, but an all-over wrap) to protect themselves from the invading extraterrestrials. What I don't know is whether this is an inspiration for or inspired by the anti-government thing. (Or, indeed, if they are both derived from something earlier.)

I didn't think the digression into "paranoid concepts" belonged here, so I removed it. It belongs in [[paranoia]] or some other article. —[[User:Ashley Y|Ashley Y]] 18:28, Nov 27, 2003 (UTC) |

Can't find it now, but there was an item on line from about 2009 allegedly where some people from MIT had done some personal experiments for the heck of it with decent instrumentation that showed that because the cap was not a fully contiguous spheroid, it did not exhibit Faraday Cage shielding effect, but actually amplified the signal inside it. It was also mentioned in some newspaper articles. If someone has more time and interest it is worth considering including it in the article, at my age, I have other interests.

Was the term actually coined by humorists? "Tinfoil hat" seems like a pretty neutral description of "headgear lined with aluminum foil"; couldn't it perhaps have been used by serious wearers of such headgear first? --[[User:Delirium|Delirium]] 00:04, Dec 10, 2003 (UTC) |

3M Velostat would probably be ineffective. It is a conductive packing material designed to prevent packaging friction induced static electricity build-up which can damage electronic components. The film of conducting material is very thin and would probably not stop external electromagnetic radiation. There was a story some years ago of airline pilots lining their caps with tinfoil to counter the effects of increased particle bombardment at higher altitudes. Some science in that, but the protection would be negligible compared to the thickness of the skin of the plane. Probably just airline urban legend, like the flight-attendants who started growing feathers instead of body hair. [[User:Anjouli|Anjouli]] 06:59, 10 Dec 2003 (UTC) |

==Move??== |
|||
Why oh why was this moved to "tin foil hat"?? "Tinfoil" is one word. Google has 22,900 hits for "tinfoil hat" and 15,800 hits for "tin foil hat." Personally, I find it really irritating when people move much-worked-upon articles without any discussion, particularly when the move is unnecessary. [[User:Moncrief|Moncrief]] 19:47, Apr 6, 2004 (UTC) |
|||
:According to the normal rules of the English language, "[[tin foil]]" is two words - just like "paper cup" or "brick road". Your google results are probably due to [[Tinfoil Hat Linux]], which is spelled that way (a take on Red Hat Linux.) [[User:Mkweise|Mkweise]] 21:02, 6 Apr 2004 (UTC) |
|||
::According to Merriam-Webster's Collegiate Dictionary, 11th Edition, ''[[tinfoil]]'' is one word, and the word dates from the [[14th century]]. It is also spelled as a single word in the Oxford English Dictionary, so it's not an American/British issue. -- [[User:Nunh-huh|Nunh-huh]] 21:08, 6 Apr 2004 (UTC) |
|||
::''Tinfoil'' is absolutely one word. Of course it started out as two separate words but, like many compound words that have since become one word, it is now commonly spelled as one word. Look at any dictionary published in the past 40 or 50 years and tell me that they don't spell it as one word. I will take this to a larger vote if you don't agree because I am certain your moving this article was a mistake. [[User:Moncrief|Moncrief]] 23:47, Apr 6, 2004 (UTC) |

:::As I pointed out above, we have a precedent in the location of [[tin foil]] [sic]. If this page is moved, that one should be moved as well for consistency.

==Devastating comments from a reader of another forum== |
|||
:" "....It should be added that, as with all pseudoscience, there is a kernel of truth or reason to be found in the tin-foil hat story. A well constructed tin-foil hat would approximate a Faraday cage, reducing the amount of (notionally harmless) radiofrequency electromagnetic radiation that would otherwise pass through the subject's brain....." |
|||
:That statement is untrue. There isn't the slightest "kernel of truth or reason to be found in this explanation." A "partial" faraday cage (actually there is no such thing) requires grounding to be the slightest bit effective. In matter of fact, an aluminum hat (ungrounded) would become an antenna. That is, it's dimensions will make it an effective antenna at a given wavelength. Again, a tin-foil hat is not electrically grounded, nor is it grounded at RF. So, the wiki citation above is incorrect. Anyone that wears a tin foil hat to stop "radiation" is either grossly misinformed or a loon...... there aren't any other explanations, nor should there be any attempt at such. This is an example, in my mind, of the NPOV going directly against the facts. RF and its behaviors are no mystery, they are very well understood. |
|||
:To be more specific with regard to a faraday cage. To be a faraday cage and to invoke the "skin" effect, the enclosure must be 360 degrees. In the case of a tin hat beanie, there is no "enclosure" and the only way to keep the rf from "crawling" into the internal part of the "tin" skin is to ground it. Does that make it clearer? THe skin effect will only help if the enclosure fully surrounds the subject. Otherwise an ungrounded piece of metal becomes an antenna (at given wavelengths and their harmonics (odd multiples, in particular). |
|||
:"TRUE" Faraday cages are reasonably effective at RF up to 100mhz (about midway into the FM band). They are notoriously ineffective at frequencies above 100mhz. THe only exception to this would be a faradday cage with no holes, whatsoever. No air holes, no light, completely sealed metallic structure. |
|||
:Moreover, a beanie isn't even close to being a faraday cage, so the analogy is quite incorrect. |
|||
:Add-on after original posting of this one: You have now been peer reviewed, a least a little bit." |

==Response to Andries== |
|||
Oh, dear. I seem to have been lumped into the tin-foil hat crowd. Literally! My intention was not to suggest that tin-foil hats were good at shielding from RF. Only that tin-foil hats resemble Faraday cages -- which *do* have the intended effect. I have modified my contribution to emphasise that tin-foil hats are not good Faraday cages. |
|||
I should add, however, that your response contains some misunderstandings. A "partial Faraday cage" does indeed exist, contrary to your assertion; indeed, imperfections in conductivity mean that there is no such thing as a perfect Faraday cage. |
|||
The skin effect is a local process -- it does not require the enclose to be 360 degrees. Wave guides, for example, are not complete enclosures, but are of course used to channel RF in one direction (along the axis) versus others. Similarly, parabolic reflectors rely on the conductivity of the metal to partially reflect the wave towards the antenna. Before you jump all over me, yes, the skin effect technically refers only to the attenuation of the transmitted wave. |
|||
Does the RF "crawl" in through holes in the conductor larger than the wavelength? Yes, of course. But a poor FC does not *need* to be grounded to provide partial shielding. If a wave is arriving from a side of the FC that does not have a large hole, then it will be attenuated/reflected for the exact same reasons that an idealized FC would. |
|||
Finally, your assertion that to attenuate FM frequencies, the FC must have "no holes, no light," etc, is completely incorrect. There is nothing magical about 100 MHz. You just need a material with sufficient conductivity, and to make sure any holes in the FC are much smaller than the wavelength of what you wish to block. |
|||
(Hmm -- just noticed an error someone introduced into this page: "There is no one frequency at which blocking begins, since electromagnetic radiation can tunnel to a greater or lesser extent through a conductor whose thickness is comparable to its wavelength." This is not true; note that the skin depth for, say, AM, is much much smaller than the wavelength of the radiation. The person who wrote this is presumably thinking of diffraction related effects.) |
|||
In summary: this author respectfully disagrees with the comments from his anonymous referee. |

The earliest comment I can remember was from a silly movie called "Love Sick" (1983) where Dudley Moore plays a physchiatrist in love with one of his patients (played by Elizabeth McGovern). One of his other patients is a homeless guy who is convinced that the CIA, FBI, DOD, space aliens, etc are transmitting messages into his head. Moore gives him a piece of aluminum foil to play the rays. --[[User:Amcalabrese|Amcalabrese]] 19:56, 26 Nov 2004 (UTC) |

== Removal of the stuffed toy image == |
|||
I have removbed the stuffed toy image that previously illustrated this page. [[Tin-foil hat]]s are a deadly serious issue for those paranoid individuals who wear them; many of them are sufferers from [[schizophrenia]], a severe mental illness. This is a serious subject, and cuddly toy illustrations are not appropriate. We can, and should, ''report on'' the mockery of the wearers of tin-foil hats that is the most common meme regarding them -- we should not, however, take part in it. -- [[User:The Anome|The Anome]] 11:58, 25 Oct 2004 (UTC) |

== Meissner effect and perfect Supraconductor Faraday Cage. == |
|||
"Imperfections in conductivity mean that there is no such thing as a perfect Faraday cage." |
|||
Superconductor are known to offer no electrical resistance, thus allowing perfect Faraday Cage. |
|||
In addition, a Supraconductor actively excludes magnetic fields from its interior; this is called the [[Meissner effect]]. |
|||
One of the theoretical explanations of the Meissner effect comes from the [[London equation]]. It shows that the magnetic field decays exponentially inside the superconductor over a distance of 20-40 nm. It is described in terms of a parameter called the [[London penetration depth]]. |
|||
Therefore, a Supraconductor Faraday Cage might provide perfect shielding against both electric and magnetic fields. |

I'd like to defend the rationality of the choice to wear such a hat.

Yes, a couple of crank websites (either that or parodies - the first one is in the external links section and marked as such).
