The Misconception: Willpower is just a metaphor.
The Truth: Willpower is a finite resource.
In 2005, a team of psychologists made a group of college students feel like scum.
The researchers invited the undergraduates into their lab and asked the students to just hang out for a while and get to know each other. The setting was designed to simulate a casual meet-and-greet atmosphere, you know, like a reception or an office Christmas party – the sort of thing that never really feels all that casual?
The students divided into same-sex clusters of about six people each and chatted for 20 minutes using conversation starters provided by the researchers. They asked things like “Where are you from?” and “What is your major?” and “If you could travel anywhere in the world, where would you go?” Researchers asked the students beforehand to make an effort to learn each other’s names during the hang-out period, which was important, because the next task was to move into a room, sit alone, and write down the names of two people from the fake party with whom the subjects would most like to be partnered for the next part of the study. The researchers noted the responses and asked the students to wait to be called. Unbeknownst to the subjects, their choices were tossed aside while they waited.
The researchers – Roy F. Baumeister, C. Nathan DeWall, Natalie J. Ciarocco and Jean M. Twenge of Florida State, Florida Atlantic, and San Diego State universities – then asked the young men and women to proceed to the next stage of the activity in which the subjects would learn, based on their social skills at the party, what sort of impression they had made on their new acquaintances. This is where it got funky.
