Your smartphone logs- data for defining your personality traits
I have in one of my earlier posts covered the ability of leveraging a user's Facebook Likes to predict the user's personality type. Today's post covers a similar ability to accurately predict the smartphone's user personality from the the logs available on the phone.
(Note: Logs are available to any app installed on a smartphone.)
In a paper titled 'Whos who with Big-Five: Analyzing and Classifying Personality Traits with Smartphones' the authors present compelling evidence that data from smartphones can very accurately bucket the user for any trait as defined in the big five personality traits system. The big five personality traits are defined here for easy reference.
- Extroversion - Active, Assertive, Energetic, Enthusiastic, Outgoing, Talkative
- Agreeableness - Appreciative, Forgiving, Generous, Kind, Sympathetic
- Conscientiousness - Organized, Reliable, Responsible, Thorough
- Neurotic-ism - Anxious, Self-pitying, Tense, Touchy, Unstable, Worrying
- Openness to Experience - Artistic, Curious, Imaginative, Insightful, Original, Wide Interests
The authors were able to use pretty standard analytical techniques on data collected from a rather sample small size of 117 volunteers in Switzerland using a certain model of smartphone. The study would have been more useful if the sample size was higher.
The authors looked at the following data points collected by a monitoring app running on the volunteer's smartphone
- Call Logs
- SMS Logs
- Bluetooth scans via BT Logs
- Calling profiles (Ringtone, etc)
- Application usage via App Logs (for Mail, Youtube, Music)
