The reason the Discovery Institute has to constantly battle the idea that intelligent design and creationism are inexorably linked is that creationism is the basis for, not an implication of, intelligent design. Those with any inclination towards honesty will continue to make that connection. But undoubtedly the Discovery Institute will not. Honesty is not one of their stated goals. Defending the traditional doctrine of creation is.
