The role of personal beliefs in REG performance shouldn't be underestimated. The idea that our minds can directly affect physical reality is not taken for granted in our society. Nor is it generally part of our collective awareness. Because of this, it is safe to say that most people's belief systems are at least skeptical of the notion of mind-matter influence, if not in conflict with it.

Psyleron customers sometimes report that by using the REG-1, they have become aware of certain limiting beliefs, which they didn't know they had. Often, this manifests as fear of failure, performance anxiety, or sensations of the difficulty or impossibility of achieving strong effect sizes with the REG-1. Even when the customer is aware of the decades of research highlighting the mind's ability to influence random event generators, irrational and limiting beliefs may still persist.

Indeed, there may be several levels of belief in our psyches. A "working," or superficial level of belief contains the presumptions that we are aware we posess—those that we knowingly choose to believe or choose not to believe. A second, more fundamental and deep-seated level contains the beliefs that are axiomatic to ourselves and our culture. This is the realm of presumptions made about how the world works, about what is possible and what is not.

By revealing limiting personal beliefs, such as those concerning our ability to influence our own physical reality, and slowly and steadily replacing them with positive and truthful ones, these obstacles may be overcome. Psyleron customers report that, while this process is difficult, it can have profound impacts on our minds, our self-empowerment, and our ability to direct the courses of our lives.
