Persons who guessed correctly were usually accurate in guessing the type of those artists with whom they SHARED either Enneagram or MBTI personality type - the INFJs, for instance, could detect the presence of another INFJ. But the same individuals did less well when it came to guessing about artists with a personality types different from their own.
Haha. It's because of the inbuilt INFJdar. It scans for all types of overt and subtle NIfFEry.
The article was great. I actually recognize the working method described by the INFJ artists as how I work myself. Very interesting. Thanks for posting this.
It would probably be a lot easier to type someone by a writing sample because then you can see the logical pattern of their thinking processes whereas the images the run through people's minds are a much trickier business.
