A good rule of thumb for diagnosing an activity as pseudoscientific is the existence of ad hoc explanations: “my telepathic powers aren’t working today because of a force field emanating from the hostile talk-show host.” There are no “bad-gravity days” and there are no days when your TV set stops working because electromagnetic waves feel hostility.

Needless to say, there is no formal or mathematical content to ID—a “theory” that explains everything, explains nothing, and predicts nothing. ID cannot explain why millions of species were created and then became extinct. Even more importantly, it cannot explain “mistakes” in the design of living organisms such as us.

Why was progress in computing technology so fast compared with the lack of progress in space travel? The reason is very simple: computing technology is only now approaching scientific limits such as quantum uncertainty and the speed of light, while space technology has already run into its limits that derive from the basic principles of physics and chemistry.

If the Moon is made of green cheese, then Napoleon lost the battle of Waterloo.
We would be committing this fallacy (i. e., affirming the consequent) if we used this sentence to claim that the Moon is made of green cheese. Pseudosciences employ this fallacy frequently, because it enables you to claim the truth of any premise you wish simply by choosing a true conclusion.

A scientific theory is a concise and coherent set of concepts, claims, and laws (frequently expressed mathematically) that can be used to precisely and accurately explain and predict natural phenomena.
A theory should include a mechanism that explains how its concepts, claims, and laws arise from lower-level theories.
