The health marketplace has a life of its own, mostly separated from science and evidence. Generally the marketplace gets a hold of an idea and runs with it, before the science is carefully worked out. Since most new ideas in science turn out to be wrong, that means most products will eventually be found to be worthless.
One such idea is that “brain training” can improve overall cognitive function – so of course now there is an industry of products which claim to train your brain. Lumosity (just to pick a random example served up by Google) claims on their website:
* Improve memory and attention
* Shown to improve cognitive function
* Neuroscience based brain training
* Train your brain today
I always enjoy the phrase “scientifically designed” or “scientifically formulated” – they are wonderful marketing phrases that invoke “science” without making any specific claims.
