I frequently get people visiting my site when searching for personality type information on Google. It might be good to have some actual content on that now and then instead of just the link in the sidebar to Keirsey's book that I'm reading.
Here's a good collection of Myers Briggs links.
Bloginality keeps track of how many people of each Myers Briggs type have taken the test on their site. As of this writing, there are some real disparities:
Now these may just be the people who reported their results. For some reason introverts seem more inclined than extroverts to take the test and report the results. The people way at the top are all N. Then you have the introverted S types, followed by most of the extroverted types (except ENFP, which is higher). Surprisingly, P tends to be higher and J lower. T and F seem to have no bearing on this.
I'm not sure if there are any conclusions to draw, but this isn't exactly what I expected. I expect F and E to tend toward the top, with T and I tending toward the bottom. I did expect SP artisanss to be low, and that turned out correct. People of that type generally hate these tests and think they pigeonhole people into categories that people shouldn't be put into, thus confirming the tests's reliability by their own opposition to them on the grounds that they're unreliable.
If anyone's interested in MBTI enough to have read this far, and you also happen to be ISTJ and are interested in starting an ISTJ webring, then let me know. I nothing about webrings or how to start one, but I think there should be one, and there isn't. A number of Myers-Briggs types have them now, but ISTJ isn't among them. I'd join one if I knew of one.
