One of the common objections to intelligent design being accepted as valid science is that ID proponents have published no scientific papers in the peer-reviewed scientific literature in support of their conjectures. The ruling in the 2005 Dover trial, "Kitzmiller v. Dover Area School District", found that intelligent design had not been tested by the process of being published in a peer-reviewed scientific journal and was not supported by any peer-reviewed research, data or publications. Despite the Dover trial ruling, the Discovery Institute lists Dembski's 1998 book "The Design Inference" under the heading "Peer-Reviewed Scientific Books Supportive of Intelligent Design Published by Trade Presses or University Presses." The Discovery Institute describes Dembski as a mathematician and philosopher, who includes in his credentials a B.A. in psychology and postdoctoral work in mathematics, physics and computer science.
