What do chocolate and radishes have to do with Green Lantern?

At The Atlantic today, Hans Villarica interviews Dr. Roy Baumeister, one of the psychologists chiefly responsible for the ego-depletion or "muscle" theory of willpower. Under this conception, people have a limited amount of willpower at any given time; as they use it, it is depleted in the short term but strengthened in the long term (just like a muscle used in work or resistance training). In the interview, Baumeister describes one of his early experiments in which he tempted people with chocolate while asking them to eat radishes instead; this used some of their reserves of willpower, leaving less for other tasks, compared to the control group who got to eat the chocolate.

In addition to informing my academic work on willpower and character, Baumeister's work was the basis for one of my chapters in Green Lantern and Philosophy: No Evil Shall Escape this Book. In chapter 2, "Flexing the Mental Muscle: Green Lanterns and the Nature of Willpower," I draw from years of stories to show that Lanterns' willpower has long been portrayed as a scarce resource. Below, I list some of the quotes I used in the chapter, showing that the version of willpower used in the Green Lantern stories corresponds with Baumeister's work--some even decades before Baumeister and his colleagues published it!

On willpower as a muscle:

"Your mind is like a muscle unused for years. You forgot how to use the power ring." (Sinestro to Hal Jordan, Green Lantern: Rebirth #5, April 2005)

"...the will is very like a muscle. In Abin Sur, that muscle was once extraordinarily strong—so strong that the Guardians of the Universe made him custodian of a battery of power, an amplifier of the will... and of a power ring, a device to focus that amplified will." (Action Comics Weekly #642, June 1989)

On willpower as a scarce resource (which can be replenished):

"[That] took lots of willpower. That—and escaping from the energy net—has left me exhausted. I need to regain my strength." (Action Comics Weekly #625, December 1988)

"I know my ring’s got limitless power—but it is powered by my willpower. Have I got the strength necessary to make this work?" (Green Lantern, vol. 2, #149, February 1982)

"Willpower’s like a muscle, and I’ve gotten better with it year after year!" (Green Lantern, vol. 2, #200, May 1986)

On willpower, focus, and distraction:

"Can’t take much more of this. I’ve been up all night trying to find the alien... . I’m exhausted... keeping this building together is taking all my concentration... all my will!" (Action Comics Weekly #628, January 1989)

"Finding it hard to concentrate, aren’t you? With me hitting you, I mean! And unless you can focus your willpower, your ring can’t work!" (Hal to Sinestro, Green Lantern, vol. 2, #124, January 1980)

Congratulations on the book.

I recently contributed a guest post, focusing on the Ryan Reynolds film, on this exact topic, over at the "Political Jesus" blog: http://politicaljesus.com/2011/06/25/green-lantern-and-the-psychology-of-willpower/

I've never been much of a DC fan, so my analysis was based on just the film. Good to see that this is reflected in the comic as well.

Fantastic, D, thanks--yes, the movie was closely overseen by Geoff Johns, the architect of the last seven years of Green Lantern stories, who also raised the importance of willpower in the GL mythos even higher (and also added the emotional elements I discuss in my book chapter).
