Regardless of my opinions about the theory behind this test, I found the test itself to be full of vague, ambiguous, and often confusing questions that could very easily be misinterpreted. Some of the questions seem to hint at specifics without actually giving them, and could be interpreted in several different ways which might yield different answers. For several of them, my answer would be different depending on circumstances. I don't think this is a very good test to use for real evaluation of personalities.
These questions in particular really confused me:
Strict observance of the established rules is likely to prevent a good outcome. (...what?)
Deadlines seem to you to be of relative, rather than absolute, importance. (Relative to what?)
It's essential for you to try things with your own hands. (What things? While learning, or while working, or what?)
You feel more comfortable sticking to conventional ways. (What ways? Are we talking about social interactions? Planning? Work? Travel? Far too broad.)
You willingly involve yourself in matters which engage your sympathies. (...what?)
Generally, I think that many of the questions on the test could have been much more clearly worded. I have no idea how accurate my result really is. In any case, here's what it tells me:
ISFJ
Introvert(78%) Sensing(25%) Feeling(38%) Judging(44%)
You have strong preference of Introversion over Extraversion (78%)
You have moderate preference of Sensing over Intuition (25%)
You have moderate preference of Feeling over Thinking (38%)
You have moderate preference of Judging over Perceiving (44%)
I do not entirely agree with this result. I am definitely thinking over feeling. But then again, I don't agree with the theory behind these tests anyway.
