The horrific terrorist attacks on the United States on September 11, 2001, left an indelible mark on perceptions of security and threat across the world. This paper uses Schwartz's (1992) value circumplex model to examine value change across matched high school and university student samples in Finland, questioned before and after the World Trade Center (WTC) and associated attacks. In Study 1 ( N =419), security values of adolescents were higher the day following the WTC attacks than before, but fell back toward pre‐attack levels in the subsequent two samples. In contrast, levels of stimulation were lower following the terrorist incidents. In Study 2 ( N =222), security levels of students were also higher following the WTC attacks, but again were closer to pre‐attack levels in a subsequent cohort.
