How effective are tin foil hats?


Do you frequently find that you need to keep aliens from reading your brainwaves? It happens. Luckily, the research has already been done by a team at MIT, concerning just how effective a good tin foil hat is at safeguarding your grey matter.

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)

Great! Our precious brainwaves are safe!

Clearly a man who carefully follows scientific studies.

Is there a graph? You bet your ass there is!

….helmets exhibited a marked 20 db attenuation at around 1.5 Ghz, with no significant attenuation beyond 10 db anywhere else.

Graphs: Make data more awesome by at least 200%. You can trust graph experts on this because….they have a graph.

So overall, it looks like Tin Foil Technology keeps your brains safe from…whatever it is people are worried about. There is one small caveat though. While the stunning fashion statement does decrease the strength of *most* radio signals, there are a few areas on the bandwidth spectrum that tin foil hats actually increased the signal.  They’re obscure though, probably nothing to worry about there.


The helmets amplify frequency bands that coincide with those allocated to the US government between 1.2 Ghz and 1.4 Ghz. According to the FCC, These bands are supposedly reserved for ”radio location” (ie, GPS), and other communications with satellites



(The “study” came out in 2005, I just found it this week and felt it was hilarious.)

On a totally unrelated note: Walrus video.
