Eric Barker mentions about this in his book named , Barking Up the Wrong Tree.
The normal “dopamine” driven human brain behavior is a result of “DRD4″ gene.
On the contrary , DRD4-7R can lead to very harmful consequences like ADHD , alcoholism and inclination towards violence.
The author goes on and says that given the right environment and context the ill effects of the so called “bad gene” get reversed and can lead to amazing creative effects.
These people who for e.g have ADHD or autistic have immense potential who can change the world with their creativity provided they are nurtured and provided the right environment.
