According to Swedish researcher Mattias Östmar of the media analysis company PRfekt, yes it can if the blog text is analyzed with the help of statistical modeling algorithm technology that can match frequently-used words with the profiles of the standard Myers-Briggs personality types.
I remember taking the Meyer-Briggs test in high school to help me choose my career path. I'm still waiting for the call from NASA to invite me into the astronaut program.
Anyway, the statistical modeling algorithm tool is now online and free to use by any blogger on the perpetual quest for self-awareness or perhaps still mourning over the passing of Madame Marie of Asbury Park boardwalk fame.
I ran this blog through Typealyzer and discovered that I am a "Doer" - The active and playful type. I am especially attuned to people and things around them and often full of energy...engaging in physical out-door activities.
I am supposedly happiest with action-filled work which craves my full attention and focus. I may also be very impulsive and more keen on starting something new than following it through. I may also have a problem with sitting still or remaining inactive for any period of time.
Based on this analysis, it may be time to stop letting my Labrador Retriever ghost write my blog. Where's the Frisbee? Where's the Frisbee?
Seriously, Typealzer is an interesting tool that I found to be about 75-80% accurate for a basic personality profile. There's also additional tabs to determine what type of lover you are and what type of sports you're interested in - I found the the accuracy of these profiles to be about about 50%.
But then again, this is a free statistical modeling tool. How much self-revelation can you expect? Just it try it out and have some fun.
