True, n-backs don't necessarily represent cognitive improvements, but they are a method to identify changes in some kinds of mental processes.
For instance, if you do Dual 3-Back for 3 weeks with an identical supplement regimen, you can graph the progressive improvement over time. That'll give you a semi-baseline, and if all you change (in your life) is a supplement from that point, you can attribute the alterations in your typical N-Back to something supplement related.
I know, placebo effect, etc. It's not causation, just correlation. Just because correlation gets pimped out on the street corner by people with agendas doesn't mean we should ignore him. We should just be careful when we utilize his services.
