Emerging from the mystical: Rethinking Muscle Response Testing as an ideomotor effect

In plain English. This study re-examined data on Muscle Response Testing, an assessment tool some practitioners use to gauge a patient's state by testing muscle resistance, to see whether the practitioner's own expectations were secretly swaying the results (an 'ideomotor effect'). Accuracy stayed about the same, roughly two-thirds correct, whether practitioners knew the right answer or not, and only dropped meaningfully when they were deliberately misled part of the time. The authors conclude practitioner bias doesn't appear to explain how this testing works, though this is a retrospective look at data collected for a different original question, so it's a secondary analysis rather than a purpose-built trial, and it doesn't directly test EFT tapping outcomes.
