I came across this, from the author of some online MBTI related articles whose descriptions of INFJs I found to be mostly very fitting and true to me at least. (If it isn't legible I'd be happy to write it up)
This sounded reasonable to me, and I thought I'd indulge my curiosity and so I found an online test (you can take it here: Left or Right Brain Test ).
These are my results from this test, and below are the lists of words the test provides at the end that go with the different results:
Left brain 60% : 40% Right brain
ANALYTIC___________INSTINCT
RATIONAL_______________ART
OBJECTIVE__________EMOTION
SYMBOLIC_______IMAGINATION
MATH_______________MEMORY
DIGITAL____________CREATIVE
ORDER_______________MUSIC
That was pretty close to the middle, but I would say it's probably actually closer for me. Looking at the words, for instance, I'd only leave out two words for them all to describe me (digital and memory). Regardless of the test, I would say that I lean more Left brain from some descriptions and Right brain from others, so it's true I'm pretty close to the middle. Anyway, it's close enough that I don't feel I can say at all if I am one or the other.
Are you more left or right brained? By how much? The test is interesting, so share results if you'd like, and how much you agree with it, but ultimately you decide, of course, what seems right to you. You can also copy the word lists and share which ones describe you if that would be fun.
And what do you think of the above description? Does the idea that INFJs are mostly in between for right and left brain feel like a true/likely description?
And anything else you'd like to add
