Intelligent design (ID) is a pseudoscientific argument for the existence of God, presented by its proponents as "an evidence-based scientific theory about life's origins".[1][2][3][4][5] Proponents claim that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection."[6] ID is a form of creationism that lacks empirical support and offers no testable or tenable hypotheses, and is therefore not science.[7][8][9] The leading proponents of ID are associated with the Discovery Institute, a Christian, politically conservative think tank based in the United States.[n 1]
ID presents two main arguments against evolutionary explanations: irreducible complexity and specified complexity, asserting that certain biological and informational features of living things are too complex to be the result of natural selection. Detailed scientific examination has rebutted several examples for which evolutionary explanations are claimed to be impossible.
ID seeks to challenge the methodological naturalism inherent in modern science,[2][16] though proponents concede that they have yet to produce a scientific theory.[17] As a positive argument against evolution, ID proposes an analogy between natural systems and human artifacts, a version of the theological argument from design for the existence of God.[1][n 2] ID proponents then conclude by analogy that the complex features, as defined by ID, are evidence of design.[18][n 3] Critics of ID find a false dichotomy in the premise that evidence against evolution constitutes evidence for design.[19][20]
^ abNumbers 2006, p. 373; "[ID] captured headlines for its bold attempt to rewrite the basic rules of science and its claim to have found indisputable evidence of a God-like being. Proponents, however, insisted it was 'not a religious-based idea, but instead an evidence-based scientific theory about life's origins – one that challenges strictly materialistic views of evolution.' Although the intellectual roots of the design argument go back centuries, its contemporary incarnation dates from the 1980s"Numbers, Ronald L.
