It was hypothesized that the magnitude of response of an individual to a placebo is positively related to his degree of suggestibility or motivation to be acquiescent. Seventy-two normal college students were studied while reacting to a placebo. A measure of acquiescence was obtained (Bass Social Acquiescence Scale) which is based on judgments of a series of proverbs. A significant positive relationship was found between degree of acquiescence and subjective response to the placebo.
