Some Psychological Effects of Changing Public Attitudes on U.S. Vietnam Veterans

This chapter discusses the substantial effect that changing public attitudes toward the Vietnam war had both on veterans’ own attitudes toward the war and on demoralization in the U.S. armed forces toward the end of the war. In addition, as hypothesized, veterans’ negative attitudes at the time of their own entrances and exits from Vietnam, and negative changes in veterans’ initially favorable attitudes, were related to the period of the war in which they served and positively associated with demoralization. Because measurement of veterans’ attitudes toward the war at their entrance and exit occurred long after their service in Vietnam, it is possible that memory distortions played a role in these findings. However, the data indicate that retrospective bias cannot account for the differences in declining favorable and increasing negative attitudes toward the war related to veterans’ time of war entry.
