So the only example in the summary is wrong. And you can tell by reading the summary. Bravo.
They looked at six personality traits (neuroticism, extraversion, openness, agreeableness, conscientiousness and narcissism) and found that extroversion was not consistently predicted based on email address alone.
The other five traits were not only consistently agreed upon by the participants, but they matched up with user's descriptions of their own personalities.
Apparently by skipping the entire content of the paper you missed the point.
Bravo.
I am a Navy Brat. I am not employed by the Navy, the US government, or anyone in particular (when I can avoid it).
Lately, I have been feeling a powerful stirring within me. Since I'm a bit old for it to be the onset of puberty, I assume it is Respect for Freedom.
I personally choose "freedom of speech" as my favorite Freedom.
I am commited to this idea, and I am not afraid to challenge Very Powerful conventions to express my commitment.
