It is often thought that all communications majors should be outspoken extroverts. However, it is not necessary to be an extrovert to be an effective communicator. For example, there are plenty of authors who would describe themselves as introverts. Despite this, it is crucial to be willing to learn how to communicate more effectively with spoken and written language. Both introverts and extroverts can learn how to become polished and confident public speakers. It is also essential for communications students to be willing to put in the time to conduct thorough research. Effective communication is often based on research. For example, a marketing expert needs to conduct research on the target audience to design a compelling advertising campaign.
