A revolution is underway in brain research. Not long ago, it was thought that the brain you were born with was the brain you would die with, and that the number of brain cells you were born with was the maximum number you could have would. The brain was thought to be programmed to function in a predetermined way. It turns out that's not true.

The brain is not wired; it is "programmed" by experience. It was a common belief that our genes dictate our thoughts, our emotions, and our behavior. In 2010 and 2020, the press was filled with stories about how genetics determine everything we experience. There were also stories about identical twins who grew up separately but still shared the same manners or preferred the same color. Popular culture saw these stories as proof of the power of the
gene wiring.
