We assessed public response to an earthquake prediction for the San Fr
ancisco, Bay Area on a sample of households from eight Bay Area counti
es. Descriptive findings suggested that an earthquake culture exists i
n the study population. We tested criticisms of interactionist theory
- its failure to take motives for behavior and social position into ac
count - using multiple regression analysis. We conclude that motives a
nd social position matter little in determining social action, and tha
t more work is needed to determine how variations in new information c
reate ambiguity, which differentially fosters searching, the formation
of alternative definitions, and subsequent action.
