Can we get any smarter? (A conversation with my boy about neuroscience)

"Can we get any smarter?" That is the question that piqued the interest of a 14-year-old boy yesterday when he saw it on the cover of the July issue of Scientific American. 

What came next was a reading of Douglas Fox's fascinating "The Limits of Intelligence," some heavy thought in a young teenager's head, and a surprised father who rarely has a conversation with his son about neuroscience.

Plus, that same father is rarely met when he comes home from working all day to a welcome like this, "Hi dad. Do you want to go see a cool movie?"

The movie my boy wanted to see (with me!) was Limitless, a science fiction flick he'd seen before about a man who takes a drug that unlocks his ability to use the "other 80 percent of his brain." We went to see it and, as my son pointed out after the movie, all of what was portrayed was just impossible.
