No, pseudoscience simply consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. It’s more about methodology and subsequent reproducibility, not simply results. There’s an important difference here.
Even pseudoscientific fields can produce results that appear to be beneficial or effective; however, these results may not be replicable, may be the result of placebo effects, or other biases.
As the earlier wiki link states: “Criticism of pseudoscience, generally by the scientific community or skeptical organizations, involves critiques of the logical, methodological, or rhetorical bases of the topic in question.”
That “some aspects” in the earlier, previously quoted context is doing a lot of heavy lifting here. Notice the word ‘suggestion’ in place of hypnosis. The following entry is related directly to hypnotherapy in that link. If you look under Efficacy in this next wiki link, nearly all meta studies say there is inconclusive evidence to support this practice as any sort of standalone treatment. en.wikipedia.org/wiki/Hypnotherapy?wprov=sfla1 Partial evidence may hint that it is touching on something(s) we can isolate and apply in a better way.
