The underlying precept that improving your working memory will make you smarter is in doubt.

This New Yorker piece about brain training does a good job explaining the ongoing debate about the underlying science behind the phenomenon. At the controversy's center is the idea that improving your working memory--essentially your brain's ability to focus on information despite distraction--will make you a generally smarter person. The problem is that the connection between working memory and general intelligence is thin and disappearing quickly. Definitely worth a read.
