A more accurate test would be much longer, would be superised by a psychologist under nearly ideal conditions and would have ways of compensating for anomalies. This test is just designed to give an indication of what functions are dominant in a person. It is not a scientific test.
You’re right, especially since it instructed us to touch our heads and asked which hand we used. Did the test writer anticipate right-handed people would have their left hands free? Like advocates, my right hand was on my trackpad so I used my left hand. I scored a 56/44, which means I should be pretty good at math. I am not.
Not ncessarily. I scored 91 left and I was never good at math, though I’ve gotten much better as I’ve grown older. I believe I have an intrinsic understanding of math but was frightened away from it as a child. Neither my parents nor teachers had any idea of how to teach a child properly. When I showed any lack of understanding they tended to throw up their hands and write me off.
In a scientific test, some questions would be asked orally with the subject, sitting straight in a chair, not using a mouse or holding a pen or pencil.
