In recent years we’ve been told that it’s possible to get smarter with the aid of various expensive high-tech brain training tools, apps and software.

What’s more the claims made by the vendors and resellers of brain training products and services were all purportedly based on scientific evidence.
Now it appears there could be serious questions about the credibility of that evidence.
