Tested predictions from W. McGuire's inoculation theory, using both low- and high-involvement truisms, and compared them with predictions derived from the theories of Sherif and Rokeach. Results for the low-involvement truism corresponded to the predictions from McGuire's theory; those for the high-involvement truism did not. A possible expansion of inoculation theory within the framework of social judgment theory is suggested to account for results.
