Here are a few sentences to ponder:
Some commentators have suggested that the internet allows people to present idealised versions of themselves to the world. Contrary to that idea, Yarkoni found that bloggers' choice of words consistently related to their personality type just as has been found in past offline research.
More neurotic bloggers used more words associated with negative emotions; extravert bloggers used more words pertaining to positive emotions; high scorers on agreeableness avoided swear words and used more words related to communality; and conscientious bloggers mentioned more words with achievement connotations.
Can we all agree that the cited post represents a considerable success? And might it apply to blog commentators as well?
Addendum: Arnold Kling comments.
