There is the right answer; you shouldn’t. There is also the grey response; sometimes it is okay. With the stress everyone faces these days, let’s be real. Sometimes the cursing (or “cussing” as we say down here in Atlanta) feels plain good.

But do be careful about who hears you AND about making it a habit. I sat next to another speaker recently whose body visibly shook as she heard our mutual colleague use a few choice words. Also – it just is not a career enhancing move to be known as the office potty mouth.

Who do you think curses more? Introverts or Extroverts? Because they talk more, are outies the number one cursers? Or, because introverts sometimes bottle up their feelings, do they let them out in form of expletives?

What do you think?

Francesca Gino ran the study along with professors Adam M. Grant of the University of Pennsylvania’s Wharton School and David A. Hofmann of UNC Kenan-Flagler Business School. Their article, “Reversing the Extraverted Leadership Advantage: The Role of Employee Proactivity,” will appear in the Academy of Management Journal next year.

Note: Extroverted can be spelled with an “a” – the strictly Jungian version. I choose to go with the commonly accepted spelling “o”. Neither is right or wrong:)

Want to hear more? Listen to Dr. Gino’s interview. She explains the study and the potential implications. We have already had a delightful exchange and are meeting soon to share our mutual findings. Stay tuned.

“They used a method known as the “oddball task” in which subjects see a series of very similar images, such as a bunch of blue cars, and then all of a sudden, a slightly different image appears, such as a red car. In the current experiment, subjects saw a series of male faces and every so often a female face appeared. They were also shown pictures of purple flowers interspersed with pictures of yellow ones.

Electrodes placed on the subjects’ scalps recorded the electrical activity in their brains, a technique known as electroencephalography, or EEG. The researchers studied a particular change in the brain’s electrical activity known as P300.

The higher subjects had scored on a test for extroversion, the greater their P300 response was to human faces. In other words, extroverts pay more attention to human faces (P300 can be seen as an indicator of human attention, or how fast their brains’ noticed that something has changed.) There was no link between scores on extroversion and the P300 response to flowers. Introverts had very similar P300 responses to both human faces and to flowers.”

“They (Introverts) just didn’t place a larger weight on social stimuli than they did on any other stimuli, of which flowers are one example,”  said.

“[This] supports the claim that introverts, or their brains, might be indifferent to people — they can take them or leave them, so to speak. The introvert’s brain treats interactions with people the same way it treats encounters with other, non-human information, such as inanimate objects for example,” Inna Fishman said.

The researchers concluded, “The results strongly suggest that human faces, or people in general, hold more significance for extroverts, or are more meaningful for them.”

The ideas here should not be taken as absolutes but perhaps are true to some degree. Keep in mind that the sample size was small (only 28) and limited (ages 18-40) More research should be done on this hypothesis. But it is an interesting start.
