Gish gallop
Also called firehose of falsehood (related), argument by volume.
Overwhelming an opponent with a rapid flood of weak arguments.
What it is
Presenting so many arguments, claims and half-truths, without regard to their accuracy or strength, so quickly that the opponent can’t possibly respond to them all in the time available.
The pattern
Make twenty claims in two minutes. The opponent rebuts three. “They couldn’t answer the other seventeen!”
An example
In a two-minute answer, a debater lists fourteen “problems” with a vaccine (some misquoted, some long outdated, some invented) and later claims their opponent “couldn’t answer most of them”.
The opponent had time to address only a few. That says nothing about whether the others were true.
Why it fails
The number of claims says nothing about their quality. The tactic exploits an asymmetry: a false claim takes seconds to make and minutes to refute. Unanswered points aren’t conceded points.
When it’s not a fallacy
Most lists skip this part. Calling a fair point a fallacy is a mistake too.
It can be fair when
- Several strong, independent arguments are made at a pace that allows a response. Having many arguments isn’t the problem; drowning out scrutiny is.
Try one
A question from the app. The wrong answers are its usual look-alikes.
City forum thread on a rent cap. Jamal, for the cap, posts 40 links in one comment: studies, news stories, tenant videos, charts. A landlord goes through the first five and shows three are about another city’s law and two never mention rent. Jamal: “Five out of forty. Read the other 35 and get back to me. Until then, the evidence is on our side. I’ll be at the council meeting Thursday if anyone wants to talk in person.” The landlord: “See you there. I’ll bring coffee.”
What’s the flaw?
Jamal posts more sources than anyone could reasonably check, and all five that were checked missed. Treating the 35 nobody has had time to read as proof turns volume into evidence.
A fair reply
“All five I read missed, so send me your single best one and I’ll read it properly.”
Often confused with
- Red herring
A red herring distracts with one irrelevant topic. A Gish gallop overwhelms with sheer volume.
- Kettle logic
Kettle logic offers several arguments that contradict each other. A Gish gallop offers many that needn’t contradict, just too many to check.
Where the name comes from
Named after Duane Gish, a creationist debater known for rapid-fire claims. A gallop is a horse’s fastest pace: the points come faster than anyone can keep up. “Firehose of falsehood”, a related name for nonstop propaganda, pictures false claims sprayed too hard and fast to catch. “Argument by volume” wins on the number of points, not their quality.
Coined in 1994 by the anthropologist Eugenie Scott, who named it after the creationist debater Duane Gish. The effort gap it exploits was summed up in 2013 as Brandolini’s law: refuting nonsense takes far more energy than producing it.

In the app
Practice spotting it on arguments that sound real.
Steelman has more examples of Gish gallop, how to answer it in a real conversation, and practice rounds that mix it with its look-alikes, so you learn the difference, not just the name. Coming soon to iPhone and Android.
You’re on the list.
We’ll email you the day Steelman is out.
