It's not foolproof, much like a lie detector test. But I do think it has value. I'm an INTJ, and understanding that other people are wired differently in very demonstrative ways, helped me understand how to relate to people. When I thought people were "phony" it was just that they were more extroverted than me. I've been told I'm too black-and-white, whereas I hated the wishywashiness in people that couldn't be decisive. This is also reflected in the Myers-Briggs test. So it might not be completely accurate, but it did help me understand how I relate and differ with others due to these 4 major personality characteristics.
