Likewise, security-awareness programs must realize that their campaigns need to account for the entire company. This means that they need introverts who understand the fundamental processes of security and extroverts who can understand dozens of diverse types of people in the population and how to translate the processes to the entire organization.

I could go on, but fundamentally there is nothing wrong with introverts. We need to understand that there are basic differences in people and that these differences do not make anyone inferior, just different. People are just different. Deal with it! And as the French say, though usually they're not referring to the introvert-extrovert dichotomy, "Viva la difference!"
