Your teeth are natural mind-control blockers. Dentin is the best radiation-absorber this side of lead paint!

So let’s assume that radio waves can control your mind and that tinfoil can stop the radio waves… what good is covering just the top of your head? Couldn’t the radio waves strike the mind from a lower angle? This defense is basically useless.

I took some antenna theory courses back in the day and yes, you are correct. Some frequencies reflect off the upper atmosphere so there would be a longer effective range at higher incident angles (going into the top of the head) but it wouldn’t completely block radio waves. Going from memory, the wavelengths that reflect off the upper atmosphere are long enough that a tin foil hat wouldn’t cause much interference anyways.
TLDR: Fashionable, but not practical.

Just to add - this “hat” would also likely improve reception.

Certainly could if it had good contact. If it was air gapped (held up by hair), it could be an effective barrier for shorter wavelengths.

Lower frequencies (like the HF range) can propagate further due to reflection/refraction with the earth and the ionosphere. Increasing the frequency can lead to e-skip and troposhpeheric ducting. But even the HF range has shorter wavelengths than our brains, which operate in much lower frequencies (Hz vs MHz). So you would think that our brainwaves would pass through tin-foil much more easily
But it’s the tin-foil’s electro-conduction that “foils” the electromagnetic waves’ (i.e radio waves’) ability to pass through it. But you would have to have no gaps in the tin-foil to completely block all waves from passing through. So like, an entire foil suit or a walking Faraday cage.
TL;DR - it’s not about the length of the electromagnetic wave, it’s the electro-conduction (insulating) property of the tin-foil that matters

people who seriously think stuff like that is real don’t subscribe to the same model of reality as we do, they just merrily invent models to describe things in whatever way enables their delusions.
they don’t think of radio as anything so fancy as waves or particles, it’s just a nebulous concept that works however they need it to for them to justify their insane beliefs.

There’s a small group of very talented gnomes inside of all radios that replay any songs they have heard before. This use to be a great arrangement for all gnomes and humans as the gnomes would receive housing and the humans get music.
Unfortunately gnomes are greedy lil shits and they ruined their cultural practice with advertising and rampant capitalism. They have completely destroyed their art form and integrity for the almighty dollar resulting is the decline of radio and the gnome housing crisis. The gnomes moved to the internet but over-saturated the music market making their was of living no longer viable. A few gnomes that have cornered the market while the rest live in abject poverty unable to compete.

see… AM radio waves go up and bounce down, this makes it so they can travel farther and give you better reception when you are out in the boonies but the cost comes when the weather isn’t very good. FM broadcasts its waves in a more side ways that works best with line of site.
This lady is clearly frightened of the AM talk radio and religious nut waves coming from they sky and not of the cool easy jazz and soft hits of the 60’s 70’s and 80’s

I take apart bombs, missiles and other explosive ordnance for a living, and sometimes we have to wrap certain components or fuzes in aluminum foil to lower the effects of RF on them for transport. The general rule I follow is if you could put it underwater and water would get in, then radio frequencies won’t be deadened. So if she wants to be protected then she would have to create a watertight seal around her head and do us all a favor.

You’re asking them to think. That’s your first mistake.

I think it’s dumb to assume they don’t think at all. It is just that their thinking is seriously flawed

Also if you do wear a tinfoil hat, there is no brain worth protecting in there. My favorite paradox
