Dunno if it's a scam, but that forehead patch makes wearers look retarded. Also the product name makes you thound retarded when you thay it.
But maybe no one will notith.
True, it may not be a scam. At least not intentionally, I'm sure the designers genuinely believe what they have made is real, so that would make it legit, just nonscientific. I've seen devices like this before, and the kicker that sets me off is always how many things it can regulate, they claim it can give you energy, boost motivation, help you unwind, help you sleep better, boost focus, etc... These can be huge mental struggles for everyone at times, so obviously we want a quick, non-invasive solution to help us. However, the thync and its pie-in-the-sky claims are dubious at best. If it was truly that simple to control all these things, effectively, and measurably in a scientifically repeatable trial with real result, I feel like there would be scientific journals and companies springing up all over the place jumping on this, not just the occasional snake oil cure all company. This seems to be an all-encompassing cure all, and to my knowledge, the only real way to alter cognitive function non-invasively via electromagnetic impulses is with a TMS machine, like Ben Krasnow with that scary huge coil he was dumping a capacitor bank into to screw with his primary motor cortex. I'm sure the thync is playing fast and loose with real science, and I'm sure there is some science behind this, however I also feel that this device in no way actually uses it. just a 300$ placebo you strap to your head that buzzes on your skull.
I'm obviously not certain about any of this, these are just my first impressions of them.
