No no no... come on, think about it. If one tinfoil hat will amplify the effect, then two tinfoil hats will only quadruple the effect of the amplification. What you need is a mercury-foil hat for your tin-foil hat; not only will that cancel the amplification effect, but it will reverse the polarity of the signal from the cell phone towers and allow you to control the government's propaganda machine. You just have to perfect the making of mercury foil, and everyone who tries is tracked down and assassinated by the government's secret police. They want you to believe that it's because mercury fumes are toxic... but they can't fool me, I know the truth.
