Argument: Observing your brainwaves can improve well-being in relation to concentration, stress, performance, and other behaviors.
3 Criteria:
- It would need to be valid and reliable at measuring brain signals
- Measured brain signal would need to accurately reflect a given behavior or mental state
- Providing individuals w/ brainwave data would need to help them alter a behavior or mental state (ultimate goal...also a crazy claim)

79
How are DTC EEGs classified by the FDA, and how are DTC EEGs marketed in this regard?
- Classified by the FDA as a medical device... DEPENDING on their intended use
- Marketed for... medical diagnosis/monitoring = stringent/strict regulation
- Marketed for... general use & "wellbeing" = less regulation
FDA will not enforce if the item is deemed "low-risk" and marked for "general wellness"
80
How is wellness defined?
Wellness = physical fitness, stress management, mental acuity, learning capacity, and sleep management
VERY VAGUE UMBRELLA
81
