According to a 2005 Harris poll, 10% of adults in the United States viewed human beings as “so complex that they required a powerful force or intelligent being to help create them”. Zogby polls commissioned by the “Discovery Institute” show more support but these polls suffer from considerable flaws, such as having a very low response rate (248 out of 16,000), being conducted on behalf of an organization with an expressed interest in the outcome of the poll, and containing leading questions.

A May 2005 survey of nearly 1500 physicians in the United States conducted by the Louis Finkelstein Institute and HCD Research showed that 63% of the physicians agreed more with evolution than with Intelligent Design.
