You raise valid points about the lack of rigor described in the link. If this is mere advertising, oh well. If it's an authentic personal experience, then I'm a bit more intrigued by his findings. It definitely reads like what I'm currently going through in a different context, but for the same problem. Your entire post ignores the fact that this is a story about one person's experience & doesn't require the sort of rigor you're suggesting. The goal wasn't to create something for everyone to use; it was to help fix himself. The application of the scientific method has become too objective when the individual subject's experience is completely ignored. We need to reintroduce the subjective into several scientific fields. For example, the mind is impacted by our neurochemistry & can also affect our neurochemistry. Yet few drug studies examine or control for patient mindset or emotional state. Science for improving humans needs to take into account the whole human experience.
