suggests that "Polish jokes" did not originate in Nazi Germany but much earlier, as an outgrowth of regional jokes rooted in "social class differences reaching back to the nineteenth century." According to Davies, American versions of Polish jokes are an unrelated "purely American phenomenon" and do not express the "historical Old World hatreds of the Germans for the Poles. However, Hollywood in the 1960s and 1970s imported the subhuman-intelligence jokes about Poles from old Nazi propaganda." For decades, Polish Americans have been the subject of derogatory jokes originating in anti-immigrant stereotypes that had developed in the U.S. before the 1920s. During the Partitions of Poland, Polish immigrants came to the United States in considerable numbers, fleeing mass persecution at home. They were taking the only jobs available to them, usually requiring physical labor. The same ethnic and job-related stereotypes persisted even as Polish Americans joined the middle class in the mid-20th century.

In spite of the plight of Polish people under Cold War communism, negative stereotypes about Polish Americans endured. Since the late 1960s, Polish American organizations have made continuous effort to challenge the negative stereotyping of the Polish people once prevalent in American media. The Polish American Guardian Society has argued that NBC-TV used the tremendous power of TV to introduce and push subhuman intelligence jokes about Poles (that were worse than prior simple anti-immigrant jokes) using the repetitive big lie technique to degrade Poles.

The "Polish jokes" heard in the 1970s were particularly offensive, so much so that the Polish Ministry of Foreign Affairs approached the U.S. State Department about that, however unsuccessfully. The syndrome receded only after Cardinal Karol Wojtyła was elected Pope, and Polish jokes became passé. Gradually, Americans have developed a more positive image of their Polish neighbors in the following decades. In 2014, a German speaker joked during the European Aquatics Championships that the Polish team would be coming back home in "our cars".
