Hypnotisability was considered as fixed as IQ until a 2024 Stanford trial changed that assumption in 92 seconds. I mention this because the people most likely to dismiss hypnotherapy for themselves are often the ones who would benefit most from knowing it.
I see a specific pattern in high performers when hypnotherapy comes up. They do not dismiss it outright. They dismiss it for themselves specifically: too analytical, too in their head, tried it once, and sat there fully aware of everything, which they took as evidence it was not working. Some have built their professional identity around thinking clearly under pressure. The idea of letting go runs directly against what made them effective. That belief feels like self-knowledge. It is actually a description of their dorsolateral prefrontal cortex.
The DLPFC governs focused attention and working memory. It is also a key neurological lever for hypnotisability. The Stanford SHIFT trial, published in 2024, targeted the left DLPFC with transcranial magnetic stimulation in people initially low in hypnotic responsiveness. Ninety-two seconds of stimulation using a theta-burst protocol. Hypnotisability increased. The implication is that responsiveness to hypnosis reflects a state of connectivity between the DLPFC and the default mode network, and that state is not fixed.
What this means practically is that high performers who report hypnosis did not work on them are almost always people who could not stop monitoring the process while it was happening. That monitoring is not the problem. The DLPFC stays active in hypnosis. What changes is which network it is communicating with. Instead of feeding the default mode network’s running threat assessment, it starts receiving direct body-state information from the insula. The executive function stays. The threat loop loses its input.
The question was never whether your brain is capable of change. The more useful question is what your nervous system has spent years classifying as dangerous that you have been calling a personality trait. In my Edinburgh hypnotherapy practice, that is usually where the most interesting work begins.
