Typealizer claims the ability to identify your personality type based on a substantial sample of your writing. Blogs make a good data source. While I am skeptical, I did give it a try and the results make some sense. Actually, my wife gave it a try and said this sounds exactly like you.
Typealizer categorized me as “Scientist” – long-range thinking and individualistic, intellectually curious and daring. Sounds good so far. It also says “scientists” tend to be so abstract and theoretical they may difficulty communicating their vision to others. I suppose some of my students might agree.
My wife’s blog – With eyes wide open – also resulted in a positive category. “The Doers – high energy and social. Especially atuned to people. Impulsive and more keen on starting something that following through.
I have been trying to figure out if I would rather be a thinker and individualistic or high energy and social. I guess you are what you are.
I make no claims for this service and the developers suggest that the results should not be taken too seriously. I wish they gave a little more information on what features their system picks up on.
