I like knowing the personality type of others because it is a guide ..simply a guide.. to tell me whether I'm more or less interested. First of all.. the fact that the person thought highly enough about self knowledge to even know their own personality type and to feel it important enough to mention it, says a lot for me. It automatically shows me they are more compatible to me than many others. The whole..know thy self thing ;-)
I wouldn't completely discount any person based solely on that info.. but lets face it.. that exists for a reason and if based on my personal experiences, I know I get along great with one type over another.. it's a very helpful tool to help you sift through a lot of potential 'others.'
Someone who truly understands personality types will at least know if the relationship may pose more or less conflict due to the varying needs of each personality and their communication styles, etc..
So yes, I was impressed that you indicated yours being INTP and knowing what that means.. and valuing that you know yours.. I continued reading with a smile :-)
