Gish's Law is a principle that suggests that the amount of time spent defending a position in a debate is inversely proportional to the amount of evidence supporting that position. In simpler terms, the less evidence someone has, the more time they may take to argue their point. This often leads to lengthy discussions that can distract from the lack of solid proof. The law is named after Duane Gish, a prominent creationist and debater known for his ability to dominate discussions despite limited scientific backing for his claims. Gish's Law highlights how debates can sometimes focus more on rhetoric than on factual accuracy.
