I earlier posted a survey on this group. I received mails saying that the questions were a little weird and many in number. So I designed a new survey that has less questions.
Here is the link to it.
This website is hosted on Google.
The findings will be published in a while. Actually at the INTP and ISTP forum there were some objections regarding the content of the survey, due to which the it was re-designed.
I would be obliged if you could again fill the form whenever you find the time!
