But one of the paradoxes of soft power is that propaganda is often counterproductive, owing to its lack of credibility. During the Cold War, open cultural exchanges – such as the Salzburg Seminar, which enabled young people to engage with one another – demonstrated that contact among populations is far more meaningful.
但软实力的一个悖论是宣传常常起到反效果，因为宣传缺少可信度。冷战期间，开放的文化交流——如让年轻人互相交流的萨尔茨堡研讨会（Salzburg Seminar）——证明了人口之间的联系要有意义得多。
