Ever wonder where we get the concept of right brain/left brain? Here's a link to find out.
Now, why does it matter? Dr. Gazzaniga, the scientist behind right brain/left brain research, argues that ultimately, responsibility is a contract between two people rather than a property of the brain, and determinism has no meaning in this context. Further social constructs like good judgment and free will are even further removed, and trying to define them in terms of biological processes is, in the end, a "fool’s game."
So yes, learning responsibility is best done in a nurturing environment as are the meanings of good judgment and free will.
