Mark Twain's Personality Scores

To create these author personality profiles NextUser sourced a collection of personal writings, including a collection of quotes, from hundreds of popular authors which were then fed in to IBM Watson. IBM Watson, through the power of cognitive computing, then analyzed these writings to provide a range of scores. These scores are based on 47 unique traits that measure the personality characteristics, values, needs of each author. Every trait is scored on a percentile compared to the average user base in our study. For example, an author may receive a 78% adventurousness score, meaning that this author is more adventurous than 78% of users in our study.

IBM Watson also infers certain aspects of a product that will resonate with an individual across twelve needs: Excitement, Harmony, Curiosity, Ideal, Closeness, Self-expression, Liberty, Love, Practicality, Stability, Challenge, and Structure.


Last, but not least, IBM Watson can identify values that describe motivating factors, which influence a person's decision-making across five dimensions: Self-transcendence (helping others), Conservation (tradition), Hedonism (taking pleasure in life), Self-enhancement (achieving success), and Open to change (excitement).
