From the article:
Why do we care about the psychoanalysis of a Star Wars villain? Because the diagnosis helps explain why teenagers -- no strangers to borderline personalities -- find Skywalker so appealing, said study co-author Rachel Rodgers, a psychologist in Toulouse. They may like him, she said, "because he's very similar to them."
Hmm. What does that say about people who dress up as storm troopers? Or Jedi? Or even the Dark Lord (Vader, not the generic term Dark Lord (tm)...) himself? Tribal formation indeed! This need to form groups with similarly-minded people can have amusing consequences: imagine the sight of a fistful of Vader-clones.
Still, say what you will about The Great Lucas's vision, the community (fan-base) expression Star Wars is has been, and will continue to be, a force for good. ;p
HAPPY 30th BIRTHDAY, STAR WARS!
