Abstract
In Spiegel's Hypnotic Induction Profile (HIP), a scale for measuring hypnotic responsiveness, the claim has been made that the eye-role sign (ER) can predict hypnotizability usable in clinical practice with a success rate of 75%. Using data from thousands of clinical cases, the ER correlated .22 with other items within the HIP--not high enough for predictive purposes. The present analysis shows how clinical observations uncorrected by statistical analysis can lead to illusory interpretations.Keywords
