Popping pills won’t boost your brainpower if you have average or above-average intelligence, according to a new paper published by the Association for Psychological Science.
“Are you going to be able to manipulate your physiology to make yourself smarter?

Published in the journal Current Directions in Psychological Science, the paper analyzes existing studies on intelligence among humans.
