A dishonest creationist debating tactic shouldn’t go unchallenged in American life. Or in national politics

June’s fateful Biden vs. Trump debate led not just to the sudden ascension of Vice President Kamala Harris as the presumptive Democratic presidential nominee. Donald Trump’s performance also saw the return of a familiar tactic in American public discourse, the “Gish gallop”—an avalanche of nonsense presented as fact—on the debate stage. A favorite of creationists, the gallop’s trot into the political arena needs calling out as we head into the home stretch of the 2024 election.

Coined by the National Center for Science Education’s founding director Eugenie Scott in 1994, the Gish gallop takes its name from the creationist Duane Gish, who frequently challenged biologists to debates about evolution. His tactic consisted of talking fast and with confidence, bombarding opponents with falsehoods, non-sequiturs and enough cherry-picked factoids to confuse the audience. Scientists debating him faced the challenge of sifting half-truths from outright lies and finding the right evidence to refute them systematically, all within the few minutes allowed in response. Which effectively meant that when the bell went off, the Gish gallop left the scientist “stumped” and Gish declaring victory for creationism. Such a spectacle leaves the audience less informed than they were before the debate, all at the hands of a debater whose only goal is to discredit their opponent and “win” the debate.
