Researchers Prove Tin Foil Hats Boost Receptivity To Government Signals

You know the old bit about putting tin-foil on your head to keep the government signals out of your brain? It turns out cladding your head in tin-foil has the opposite effect.

Researchers at MIT, using a network analyzer, tested the impact of tin foil helmets on receptivity of radio-frequency signals. They highlight the method and results in the study abstract:

Among a fringe community of paranoids, aluminum helmets serve as the protective measure of choice against invasive radio signals. We investigate the efficacy of three aluminum helmet designs on a sample group of four individuals. Using a $250,000 network analyser, we find that although on average all helmets attenuate invasive radio frequencies in either directions (either emanating from an outside source, or emanating from the cranium of the subject), certain frequencies are in fact greatly amplified. These amplified frequencies coincide with radio bands reserved for government use according to the Federal Communication Commission (FCC). Statistical evidence suggests the use of helmets may in fact enhance the government’s invasive abilities. We speculate that the government may in fact have started the helmet craze for this reason.

While their conclusion is a bit tongue-in-cheek, the irony of foil helmets increasing reception of government-reserved radio frequencies is certainly not lost on us.

On the Effectiveness of Aluminum Foil Helmets: An Empirical Study

If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    Well, duh! You have to ground the hats for them to be effective.

    1) Find a schizophrenic with a foil hat on
    2) ???
    3) Watch him try to find a new hat

    Anyone who is actually serious about avoiding government mind control wears a Faraday Cage Hatâ„¢ with carbon fiber ground straps.

  5. UltimatePSV

    But what if this is a government hoax to get us all to stop wearing them?

    Only those Americans to think of something stupid like that!
    Aluminum hats are only to pack their own brains.

    Don’t take me wrong, I have nothing against the Americans, but it’s funny.

  7. Steve-O-Rama

    Oh for the love of tacos, PLEASE stop calling it TIN foil!

    Hey, SCBright! As an American I resent that! We have a lot more stupid ideas than that! Er, um, I mean, I think that’s what I mean! Maybe…

    Hence the replacement, The Fez – it’s cool

    They all posess adequate ‘ufer grounds’ that could be connected to the hat with a piece of #8 hard-drawn copper wire and two clamps. It requires an eight foot long, copper-clad ground stake burried seven feet in a damp location. RF leakage problem solved!

    Curses! Foiled again!

    Well, of course… it is aluminum… not tin. They only mentioned three designs and did not show them. You have to form pointy shapes from the top to disrupt all signals. And as far as “you” Americans, forget about it… just look where we “escaped from” to help understand why the crazy and ridiculous hasn’t filtered out yet… we are still attempting to dilute all the inbreeding that went on while our ancestors lived in England.

    It is too late anyway after all these years. “The Man” has the majority of the population ready. When “they” flip the switch and turn everyone into zombies the only thing that will matter is how much food and ammo you have stored in your underground bunker.

    I am gonna get me one of those Australian Hats with the corks to ward off flies and replace the corks with high power magnets !

  16. Jim

    C’mon, I saw the movie “Signs” and I know the tin-foil hats need to have a point on the top to be effective!

    The entertainment industry has been sucessfully doing mind control for many years. Hence Obama’s election and acceptance of anything he does.

  17. Kevin

    I have to go with the FEZ as a replacement, Dr. Who is FEZ fan and we all know what a trip in the tardis can do……….

    Sure it may not help you from keeping the government from reading your mind but now what are we supposed to about communicating with those planet x aliens?

  20. Jeff

    the reason that radar cannot detect stealth aircraft is because of the multiple angles of the surface and the special paint used on it. Common sense would tell you then to crumple the tin foil and paint it flat black before making a hat of it! Besides that’s what my mama told me would work.

  21. WizardEmrys

    Yeah but if you keep it on your heal you will pick up more Television stations for your digital Television!

    I meant to say head!
