It's actually a very very good result for the tests we did. A similar study using a boatload of caffeine couldn't reach statistical significance. Also I believe strongly that if we'd compared it to say, classical music or some random ambient album, it would have been an even stronger result. The placebo in this study was still generated by the AI, so it followed the same rules - rules that naturally help people focus. The only thing it lacked was the brainwave stimulating modulations. We did see a big difference on an EEG because of that, but the fact is that part of what makes the sessions work is that they follow strict rules, and there's nothing wrong with that. It just makes it harder in this case.
But I actually like it like that. I want a double blind study with identical-sounding placebo and more subjects. After that we can study how it compares to regular music commonly used as study-aids.
Regarding the statistical analysis, result interpretation, etc, I feel I should let Giovanni himself defend his paper. He's dealing with family / health issues right now, but I hope to get him on here as soon as possible. I promise he will respond eventually and clear this up.
