Since the explosion of smartphones into society, more and more people are using smartphones to handle all technology related communication. While it is easier and faster to text than to email, it has given rise to a new language riddled with text-isms. This study focuses on professionalism in written computer-mediated communication, while seeking to understand what causes people to lack professionalism in their messages. We focus on three predictors, the need for popularity among peers, the extent of texting and instant messaging, and how conscientious an individual is. One hundred students completed a survey on professionalism. We found that conscientiousness causes professionalism, while the need for popularity causes one to lack professionalism. We also found that the number of texts one sends does not matter, but the frequency one instant messages causes one to lack professionalism in written computer-mediated communication.
