What if you have more intelligence than you realise? What if there is a genius inside you, just waiting to be released? And what if your route to better brain power is not hard work or thousands of hours of practice but to simply swallow a pill? What if your intelligence could be increased on demand at the touch of a button?In The Genius Within bestselling author David Adam turns his award-winning analysis and prose to the pressing scientific and societal issue of cognitive enhancement. He reveals the potential - and limitations - of intelligence and how it shapes our society. Going to the heart of how we consider, measure and judge mental ability, The Genius Within plunges into deep ethical, neuroscientific, and historical pools of enquiry about the science of brain function and what it means for us all.
