Never go shopping hungry. Your willpower is sorely depleted, and you stand a good chance of ending up with bags full of impulse buys and a trolley full of treats. That's the implication of research covered in typically fine style by Roy Baumeister in this issue (p.112).
According to Baumeister, psychologists are bringing back the notion of willpower as a limited supply of energy that is used for control and self-discipline. Read on to discover how 'the moral muscle' is implicated in everything from judges' parole decisions to premenstrual syndrome.
I hope you are finding the 2012 additions to The Psychologist engaging and informative. Some welcome and positive feedback on the January issue was directed @psychmag and @jonmsutton in recent weeks. The Psychologist and Digest Policy Committee and I very much want and need this guidance in order to plot our course. We continue to do all in our power to keep everything shipshape, and we need all hands on deck as we set sail for exciting and uncharted waters. Nothing, not even painfully stretched metaphors, can sink us.
