New drugs may help to enhance people’s mental powers (see article). But a study carried out by Pamela Smith, of Radboud University Nijmegen in the Netherlands, and her colleagues suggests a less pharmacological approach can be taken, too.

Conversely, ’empowering’ him, in the dread jargon of sociology, sharpens up his mind.
