According to recent research, Facebook profiles actually reflect their owner’s personality more accurately than a brief face-to-face encounter might manage to do:

Back’s team administered personality inventories that evaluated 133 U.S. Facebook users and 103 Germans who used a comparable social-networking site. Inventories focused on the extent to which volunteers endorsed ratings of extraversion, agreeableness, conscientiousness, emotional instability and openness to new experiences.

The subjects — who ranged in age from 17 to 22 — took the inventory twice, first with instructions to describe their actual personalities and then to portray idealized versions of themselves.

Then, undergraduate research assistants — nine in the United States and 10 in Germany — rated volunteers’ personalities after looking at their online profiles. Those ratings matched volunteers’ actual personality descriptions better than their idealized ones, especially for extraversion and openness.

Not everyone is entirely convinced, however:

Adriana Manago, a psychology graduate student at UCLA, calls the new findings “compelling” but incomplete. College students on Facebook and other online social networks often augment what they regard as their best personal qualities, Manago holds. In her view, these characteristics aren’t plumbed by broad personality measures like the ones measured in Back’s study. And students’ actual personality descriptions may have included enhancements of their real characteristics, thus inflating the correlation between observers’ ratings and students’ real personalities, Manago notes.

“Online profiles showcase an enhanced reflection of who the user really is,” Manago proposes. In a 2008 study, she and her colleagues found that 23 college students sometimes used another online social networking site, MySpace, to enhance their images, say by Photoshopping acne out of a picture or posting a video of themselves driving a sports car at high speeds.

Somehow this revelation is both cheering and depressing at the same time… I wonder how those results would differ for older age brackets?
