What motivates a conspiracy theory? Birther beliefs, partisanship, liberal-conservative ideology, and anti-Black attitudes

Despite the release of his birth certificate, some Americans express continued skepticism over whether Barack Obama was born in the United States. This study examined two possible causes of birther beliefs: that Republicans and conservatives, whose ideological beliefs and policy preferences led to disapproval of the president, might be particularly prone to accepting birther beliefs, and that negative attitudes toward Blacks led some Americans to disapprove of the President and accept foreign birthplace claims. A nationally representative survey of Americans showed that birther sentiments were predominant among conservatives/Republicans and individuals holding anti-Black attitudes. These relations were mediated by disapproval of the president. Hence, it appears that birther beliefs were motivated both by politically-grounded disapproval and racially-driven disapproval of the president.
