AbstractWith product tampering becoming a more common phenomenon, the impact on consumer psychology will possibly become a major factor in consumer reaction to packaged products; consumer attitudes, as well as actions may change accordingly. This article reports on a study that examined how different demographic groups reacted to tampering. The results indicate there are some differences in the groups, especially in terms of age and education. The findings seem to point to some underlying factors that may have an effect on consumer reaction to the problem.
