INTP Ti Ne Si Fe
I've been poking around and came up with 2 things.
From the book personality type by Lenore Thomson I made the following image
and then from the dual quad brain lateralization theory
the top of the image is the back of the brain.
I can't help but to connect the dots.
Code:INTP Ti back right brain Imaginer:sees Ne front right brain Superego: IS, loves Si back left brain Reporter: hears-says Fe front left brain Thanatos: is, hates
Also, for enneagram type 5, the Id is withdrawn.
How does this correlation strike you?
