INFJ Left-brainers? Is there such a thing?

So I have recently come across a book that describes some of the differences between extraverts and introverts, one of my favorites sub-sections of personality temperaments. (The Introvert Advantage by Marti Laney). The book also differentiates between left-brained and right-brained introverts, something that I had never thought to consider when thinking about our own introverted type.

So I read through the descriptions, and even though I have always tested consistently as an INFJ (Feeling being a very important part of this), I keep getting directed in the left-brained direction, a process that is based on logic.

Which isn't really a problem except that it completely goes against the Feeling side of the inFj spectrum.

Some of the different traits between the two are:

Left-Brainers- analyze pros and cons before taking action, are usually neat and tidy, give concrete examples when describing something, are keenly aware of time, proceed one step at a time, likes to focus on one task at a time, is idea-oriented, seek exact solutions.

Right-Brainers- Playful in solving problems, respond to events with emotion, interpret body language easily, have a good sense of humor, improvise, use metaphors or analogies when describing something, deal with several problems at once, not realize all that you know.


I was wondering if any of you had ever tested you brain in this way, and are there any left-brained INFJs out there? And what does this mean in terms of our emotions if our brains by default are logic-based?

I'm open to any sorts of theory and discussion!
