These really gross, noisy EEGs are useful for some things, but they're being peddled alongside all manner of snake oil. The structure of thought and emotion is so complex and obscure that leading scientists are barely able to even define it, much less detect it with powerful, invasive tech — much less again with this type of device. If you find using an EEG device improves your life in some way, that's great - go for it. But exercise skepticism when it comes to the claims being made about just what is being detected here and with what level of accuracy and precision.
