Right,
kinesiology is a way to make contact with your unconscious via a muscular response. Usually, an answer that is true or good for you will make you stronger and something that is untrue or negative for you will make you weaker. You will calibrate and make sure of how the response feels in terms of strength before you ask a yes/no question you want to find an answer for. There are various ways of muscle testing, some of which you can practice on your own.
