"A study at MIT has found that aluminum foil headwear ("Among a fringe community of paranoids..the protective measure of choice against invasive radio signals") actually amplifies certain frequency bands allocated to the US government, as well as a mobile phone range, and is largely ineffective through the rest of the radio spectrum. But we can we trust the study, or are They controlling the researchers?"
Oh well, back to the drawing board.
Oh and please don't start confusing me with this guy
edit: a follow-up sent by my co-worker Dieter:
The invasive radio signals are a secondary concern. More importantly, the AFDB (Aluminum Foil Deflector Beanie) can shield against anti-psychotronic carriers.
We should also consider shielding our workspaces; see attached.
