However, other research shows that there are certain personality traits that lead to increased loneliness which then leads to increased use of the Internet. In particular, extroversion and neuroticism have been linked to loneliness. An extrovert is someone who is outgoing, enjoys the company of others, requires stimulation, and is spontaneous, while an introvert prefers their own company, is quiet, and prefers quiet, small gatherings. Introverts can often be seen as distant and unfriendly because of this behavior which may explain some of their loneliness. A neurotic person is extremely anxious, emotional and reacts in a disproportional way to many situations. Someone high in neuroticism generally has a negative attitude which may push people away and prevent them from forming close relationships which may lead to their loneliness. Both of these groups (introverts and neurotics) have been shown to have increased Internet use and in particular increased use of social service sites (i.e. chatrooms, newsrooms, etc.). This may show that those who are already lonely are more attracted to the Internet as a means of social networking and not that the Internet increases loneliness. Introverts and neurotic individuals have also been shown to feel more comfortable revealing their "true-self" online than in face-to-face conversation and revealing the "real you" has been shown to help the discloser to form close relationships.
