How then can we explain the individuality?
Consider a highway. The United States has one of the most extensive and complex ground transportation systems in the world. There are lots of variations on the idea of “road,” from interstate freeways, turnpikes, and state highways to residential streets, one-lane alleys, and dirt roads. Pathways in the human brain are similar.
(The bigger pathways are similar in each of us.)
It’s when you get to the smaller routes—the brain’s equivalent of residential streets, one-laners and dirt roads—that individual patterns begin to show up. Every brain has a lot of these smaller paths, and in no two people are they identical. The individuality seen at that level of the very small, but because we have so much of it, the very small amounts to a big difference in individuals.
It is one thing to demonstrate that every brain is wired differently from every other brain. It is another to say that this affects intelligence.
Rule #3 Every brain is wired differently.
• What you do and learn in life physically changes what your brain looks like—it literally rewires it.
• The various regions of the brain develop at different rates in different people.
• No two people’s brains store the same information in the same way in the same place.
• We have a great number of ways of being intelligent, many of which don’t show up on IQ

“We all are learning, modifying, or destroying ideas all the time. Rapid destruction of your ideas when the time is right is one of the most valuable qualities you can acquire. You must force yourself to consider arguments on the other side.
