Allchin's Shoehorn, or Why Science is Hypothetico-Deductive

Allchin's critique of my analysis of Galileo's discovery of Jupiter's moons, and of my characterization of science as hypothetico-deductive, contains several factual and conceptual errors. Thus, contrary to his attempt to paint scientific discovery in terms of blind search and limited induction, a careful analysis of the way humans spontaneously process information and reason supports a general hypothetico-deductive theory of human information processing, reasoning, and scientific discovery.
