Figure 3.6: President Harry Truman holding up the headline of a newspaper that had incorrectly announced his defeat. This headline was based in part on estimates from non-probability samples (Mosteller 1949; Bean 1950; Freedman, Pisani, and Purves 2007). Although “Dewey Defeats Truman” happened in 1948, it is still among the reason that some researchers are skeptical about estimates from non-probability samples. Source: Harry S.
