Just because popular social networks, such as Facebook and Twitter, encourage members to use their actual identities doesn't mean people are presenting themselves online the way they do in real life.
Some psychologists and sociologists who have studied usage habits on Twitter, Facebook and popular dating sites say there's little correlation between how people act on the Internet and how they are in person.
Research into how personality traits are filtered through the Web, especially the new breed of short-message online services, is slim, but digital-health experts have observed numerous transformations when someone ascends the Internet's world stage. Whether a person is overly chatty or arrogant on Twitter doesn't necessarily reflect on how he or she acts in the real world.
"I don't think that you could have any type of accurate or even semi-accurate personality analysis based on what people are writing in their Twitter streams. Probably the same case goes for Facebook statuses as well," said John Grohol, an online mental health expert and founder of PsychCentral.com.
