You don't. Just like you don't need light bulbs. And yet, most of us choose to use them. BT provides you with two valuable insights--identity bifurcation, and metacognition. What do those mean? First, is bifurcation. Defined as the separating into two parts. BT offers the bifurcation of who you are--via nature and nurture. Once you understand your type (inborn), then you can make sense of your past/upbringing and understand the whole of who you are, and who you've become (via nurture). No other personal assessment method (e.g. Enneagram, DISC, Myers-Briggs, Big Five, etc.) offers that insight. Second, is metacognition. Defined as one's awareness of and ability to regulate one's own thinking. BT enables you to see outside of yourself, and understand (objectively) how you think. From there, you can navigate life in a more circumspect and balanced way. BT is also has heuristic value, which is another big word. Heuristic means enabling a person to discover or learn something for themselves. BT allows you to explore your past, in learning to understand your present.

Of course it is. We have 25+ years of testimonials from scientists and people who have seen and lived it to be true. Brain Typing reveals itself in how we talk, think, move, and even in our physical appearance.

BT relies on empirical observation of body movement and phenotype (physical expression of genes) to make sense of your brain's behavior. How your body moves is always indicative of how your brain operates.

Well in the thousands, people of all walks of life have understood and applied BT to their lives.

Nothing. At least, nothing that we know of, just yet.
