If an item shows up as unbalanced then that indicates that from among numerous items tested, the body gave an above or below average electrical resistance response. In other words, the body-mind system has indicated some kind of reaction to the item being tested, and along the lines of homeopathic ideology, we can use that to ‘remind’ the organism to improve that particular aspect of homeostasis.
Consider a couple of parallels. Firstly from immunology: introduction to a pathogenic microbe initially causes a disturbance to the body, perhaps quite a serious acute reaction. However, as the information is relayed around the immune system, the body learns to cope with that particular pattern better next time.
Secondly, from psychology: a therapist mentions an event in calm conversation to his client and the client breaks down in tears – he has hit a raw nerve. Subsequent discussion desensitizes the event and places it in a context. In both these cases, a repetition of information has allowed the body to become more robustly adapted to its environment.
The QEST4 test is identifying items to which the body-mind system can learn better adaptive behaviors.
