From the Sunday Times bestselling author of The Man Who Couldn't Stop

'Witty, sharp and enlightening ... This book will make you smarter' Adam Rutherford

What if you have more intelligence than you realize? What if there is a genius inside you, just waiting to be released? And what if the route to better brain power is not hard work or thousands of hours of practice but to simply swallow a pill?

In The Genius Within, bestselling author David Adam explores the ground-breaking neuroscience of cognitive enhancement that is changing the way the brain and the mind works - to make it better, sharper, more focused and, yes, more intelligent. Sharing his own experiments with revolutionary smart drugs and electrical brain stimulation, he delves into the sinister history of intelligence tests, meets savants and brain hackers and reveals how he boosted his own IQ to cheat his way into Mensa.

Going to the heart of how we consider, measure and judge mental ability, The Genius Within asks difficult questions about the science that could rank and define us, and inevitably shape our future.
