I think of not having many friends may be indicative of introversion I'm basically a pretty friendly person, but I limit my close friendships.

It was considered a very useful tool for many years.... but as all psychology, it's not totally accurate, but it's kind of fun like horoscopes

I've taken the test more than once because I forgot the results, but it's always been the same. It's based on actual studies, unlike tarot or horoscopes.

Yes... part of it is confirmation bias. We believe what we already believe. But my results have also been remarkably consistent. When I was working I took the test several times, and no matter how much I pored over the questions, I was always an INTP. Now that I'm no longer working, I'm consistently INTJ. I think your circumstances naturally influence your mindset.

@Kynlei no, it was invented by 2 bored housewives.....

@AnneWimsey that is not true, Anne. [en.wikipedia.org]
These were educated women who studied the works of Jung for 20 years. Don't forget, it was a different time, when education and intellect among women was not valued. Much like now

See my response to of-the-mountain. There is more to the story than people's comments here. (I see today that his response has been deleted, so I refer you to the Wikipedia article on Katharine Cook Briggs.) She was absolutely brilliant. Went to college at age 14 and graduated #1 in her class. She studied the works of Jung for 20 years. To call her a just a "housewife" is demeaning to women.

Maybe you should do a little more research. Try reading the Wikipedia entry about her. She started college at the age of 14 and graduated first in her class with a degree in agriculture and became a well-known academic during a time when it was falsely believed that too much education for women harmed their reproductive abilities. She worked as a teacher after college and devoted the rest of her life to studying the theories of Jung. She and her adult daughter did 20 years of research into Jung's theories before developing one of their own. Perhaps the Myers Briggs test didn't hold up to scientific scrutiny after a time, but for many years it was the hallmark among personality tools. To demean this intelligent, educated woman and her daughter to "a couple of lonely hearts columnists" is about as misogynistic as one can get.

@TheoryNumber3

If you do proper research not BullShit propaganda put on a Wikipedia!!!

Having a degree in some form of agricultural science does not give any one the ability to classify humans in such vague distinctions!!!

The vast majority on Wikipedia is factually correct in this case full of complete propaganda!!!

Not if you do not like I think I acted sexist!?!

Simple you are simple minded sexist pig!!!

I would prefer to call it understanding myself, rather than overanalyzing.
PS: And the test is free online on various sites
