drwex and hammercock both tried this so I thought I'd give it a spin.

The IBM Watson Personality Insights service uses linguistic analytics to extract a spectrum of cognitive and social characteristics from the text data that a person generates through blogs, tweets, forum posts, and more.

We need a minimum of 3500 words and ideally 6000 words or more to compute statistically significant results. See the science behind the service.

Ideally, the text should contain words we use in every day life relating to personal experiences, thoughts and responses. See usage guidence for details.

My results:

Your Personality*

You are inner-directed and skeptical.

You are independent: you have a strong desire to have time to yourself. You are empathetic: you feel what others feel and are compassionate towards them. And you are authority-challenging: you prefer to challenge authority and traditional values to help bring about positive changes.

Experiences that give a sense of well-being hold some appeal to you.

You are relatively unconcerned with tradition: you care more about making your own path than following what others have done. You consider independence to guide a large part of what you do: you like to set your own goals to decide how to best achieve them.

*Compared to most people who participated in our surveys.

Cute, but I'm not sure if it's that accurate about me. Or maybe my writing really doesn't express my extroversion very well. The visualization is attractive, though.

IBM Watson now has 6124 of my words on file, if it matters.
