One of the most common criticisms of the movement and its leadership is that of intellectual dishonesty, in the form of misleading impressions created by the use of rhetoric, intentional ambiguity, and misrepresented evidence. It is alleged that its goal is to lead an unwary public to reach certain conclusions, and that many have been deceived as a result. Critics of the movement, such as Eugenie Scott, Robert T. Pennock and Barbara Forrest, claim that leaders of the intelligent design movement, and the Discovery Institute in particular, knowingly misquote scientists and other experts, deceptively omit contextual text through ellipsis, and make unsupported amplifications of relationships and credentials. Theologian and molecular biophysicist Alister McGrath has a number of criticisms of the Intelligent design movement, stating that "those who adopt this approach make Christianity deeply... vulnerable to scientific progress" and defining it as just another "god-of-the-gaps" theory. He went on to criticize the movement on theological grounds as well, stating "It is not an approach I accept, either on scientific or theological grounds."
