"In short, the science does not speak for itself, and as survey research shows, the first premise of scientific certainty remains selectively interpreted by the public based on their values and partisan identity."
The second premise, Nisbet explains, is a call to action that resonates with one's moral framework. Though Bush and Obama produced opposing policies, they offered similar appeals to a higher call.
Bush (in 2001): "[H]uman life is a sacred gift from our creator. I worry about a culture that devalues life, and believe as your president I have an important obligation to foster and encourage respect for life in America and throughout the world."
Obama yesterday: "As a person of faith, I believe we are called to care for each other and work to ease human suffering."
