Even so, we believe it is important to report results on many traits in a single paper. This demonstrates the power of a simple model and allows task difficulty and extracted features to be compared across traits without concerns about changing experimental setup.

myPersonality Dataset
---------------------

From 2008 to 2012, over 7 million Facebook users took the myPersonality quiz produced by the psychologist David Stillwell [@kosinski2015facebook]. After answering at least 20 questions, users were scored on the Big Five personality axes: openness, creativity, extraversion, agreeableness, and neuroticism. Over 3 million of those users agreed to give researchers access to their extant Facebook profile and their personality scores. A much smaller subset of users answered additional questionnaires about their interests, Friends’ personality, belief in astrology, and other personal information. The research community has added to the dataset by providing race labels for several hundred thousand users; representing the text of statuses in terms of their Linguistic Inquiry and Word Count (LIWC) statistics [@pennebaker2001linguistic]; and much more. Labels used in this study are listed in Tables \[acc\_cat\] and \[acc\_cont\], along with descriptive statistics. To see all available labels, visit myPersonality.org.
