This field works in a subtle and specific direction - in ancestral mastery. In your subconsciousness all the experience of your ancestors is stored, and the experience accumulated not in one area of knowledge or craft, but in many.
With a high probability you will find the case in which you are really strong. And this dramatically changes the whole life, making a person unique and highly demanded in our society. Maybe you will discover organizational skills. Or maybe you will begin to better count and generate money (if your ancestor was enterprising). It may well reveal the charisma of an artist or the urge to oratory and teaching.
In short, psychogenetics can pass on any experience. This has been proven in animals as well as in humans. The only question is how to unlock in your subconsciousness this stored and archived array of knowledge of your ancestors. And this field will help you in this.
