How much of David Hawkins’ Letting Go is actually evidence-based?
I’ve just read David R. Hawkins’ Letting Go. I can see how the technique of observing and accepting emotions might help some people. However, the book also makes many scientific, medical and paranormal claims that seem to go far beyond the available evidence.
I’m curious what others think:
- Kirlian photography: Hawkins presents Kirlian images as evidence that emotions change the human “aura”. But research has shown that many changes in these images are explained by moisture and electrical conductivity, not an emotional energy field. Why is this interpreted as an aura?

- Telepathy and emotional transmission: The book claims that minds can transmit thoughts and emotions over unlimited distances. What is the proposed signal, mechanism or receiver? EEG measures electrical activity from groups of neurons near scalp electrodes, while brain magnetic fields are extremely weak and decrease rapidly with distance.

- Quantum physics: Hawkins invokes quantum mechanics to support consciousness influencing reality and remote mental communication. But quantum entanglement does not allow controlled faster-than-light communication. Caltech explanation
- The consciousness scale: Shame is assigned 20, fear 100, anger 150, love 500 and enlightenment 1000. How were these numbers obtained? Where are the error margins, independent replications and falsification criteria? If critics are dismissed as having “low consciousness”, doesn’t that make the theory circular?
- Applied kinesiology: The book claims that muscle strength can determine whether a statement, food or person is “true” or beneficial. A double-blind study found about 53% accuracy, essentially no better than chance, and the AAAAI says applied kinesiology is not a reliable diagnostic method. Why should Hawkins’ version be trusted?
- Disease and emotion: The book suggests that most illnesses result from suppressed emotions and that releasing them can reverse serious disease. How does this explain infections, genetic conditions, autoimmune diseases, fractures or cancer? The NCI says the direct link between stress and cancer remains unclear. The NIDDK identifies H. pylori and NSAIDs as common causes of ulcers.
- “Adrenal fatigue”: Hawkins uses this concept, but the Endocrine Society states that there is no scientific proof that adrenal fatigue exists as a medical condition.
- Anecdotal cures: The book describes people supposedly curing vision problems, allergies, arthritis, diverticulitis, fractures and other illnesses through surrendering emotions. Where are the medical records, control groups, failed cases and independent follow-ups?
- Energy fields and chakras: What measurable physical structure corresponds to a chakra or meridian? What experiment could prove this model wrong?
- Plants, music and objects: The book claims that plants react to human emotions and that certain music, fluorescent lights, artificial sweeteners and synthetic fabrics weaken the body. Where are the properly controlled, replicated experiments?
I’m not arguing that emotional regulation, mindfulness or acceptance are useless. They may help with stress and subjective wellbeing. But does that justify the book’s claims about telepathy, energy fields, disease reversal and a numerical hierarchy of consciousness?
For those who have read it: which claims do you think are genuinely supported, and what would count as evidence against Hawkins’ system?
