Interesting findings but several methodological issues: most are double users hovering both FB and Twitter; most are inactive users on both; other factors to consider include education, gender and age. The personality difference should be less striking for dual, inactive users.
People who used Facebook largely to socialize tended to be younger, more social, and more neurotic — suggesting that Facebook habitués use the site partly as a tool to alleviate loneliness, the researchers said.
People who used Twitter to socialize, meanwhile, scored high on openness and sociability but low on conscientiousness. So they’d be more likely to use Twitter to procrastinate, the authors proposed.
Twitter users who did this were high on conscientiousness and need for cognition, and low on neuroticism. In short, they were focused, no-nonsense information-gatherers. People who sought information on Facebook, in contrast, were considerably less intellectually curious.
