Personality Types! in General Discussion Posted January 2, 2017 That's not what a brain works like at all. There are no "left-brained" or "right-brained" people, there are no Jung-personality-type brains, and there are no distinct brain parts dedicated to each function as implied. The Jung classification is above all, still extremely arbitrary, and in terms of neuroscience, more or less considered an outdated concept. You can pretty much test differently depending on season, or be very in-the-middle, and in the end of the day, the brain is constantly rewiring itself in small ways. They're more fun tests to take for entertainment value than something you should base your life on, or seriously describe yourself after. For me, ESTP and INTP are about equally probable, for instance. And just as inaccurate. Alright, my mistake. Thanks.
