A point refuted a thousand times, commonly abbreviated as PRATT, is a common phrase on internet forums where debates have a tendency to go in circles. Once people have refuted a point the first thousand times, it's hard for them to muster the motivation to do it again. Once someone has labeled an argument a PRATT, that usually means they have no interest in discussing it. This could itself be a diversionary tactic.
The website talk.origins acts as a repository of PRATTs commonly used by creationists, and presents (usually in great detail) their refutations and science behind them. The site is a good starting point when facing a PRATT.
 Examples of PRATTs
These assertions are mostly very easy to refute, but remain persistent arguments due to ignorance.
Fundamentalist Christians and Muslims are told to avoid reading material and visiting websites that can disturb their faith. Therefore naïve fundamentalists may repeat bad arguments because they genuinely do not know the refutations. More cynical preachers may bring out arguments that have been refuted time after time because they know the sheep who flock to hear their messages will not find out the refutations.
 Religious examples
- Religion is required in order for a person to be moral.
- If this were anywhere near true, the world would be in chaos as Adherents.com reports that a fairly sizable 16% of the world population have no religion. That's nearly 1 in 6 people who would happily murder you because they lacked any form of morality - this just doesn't stack up to observed evidence. Secular humanism has established several non-religious moral codes, and biologists and psychologists have tracked various evolutionary pathways for why we act in (what we define as) a moral manner. Perhaps most importantly, statistical analysis (rates of murder, adultery, rape, theft, etc.) shows that non-religious folks behave no less morally than those who have found religion (or had it hammered into them since childhood).
- Atheism is a direct cause of lawless behavior.
- This is similarly untrue for almost all beliefs, with the notable exceptions of illegalism and nihilism. Of course, even illegalists could be said to follow a law of their own devising: that society is bad and should be destroyed.
- If this was true, most of Scandinavia would be well-known as a hotbed of insane, Godless violence. As it currently stands, it isn't. Neither is there much obvious correlation between lawlessness and religion as most causes of crime are attributed to social and economic conditions. Religion, or lack of it, isn't often viewed as a contributing factor.
- Atheism is a religion.
- While it's pretty certain some people can be quite passionate and organised about atheism - and even issue out religious-like edicts about what atheists should and shouldn't do - atheism itself is not a religion. It has no dogma to follow and is a completely non-prescriptive belief system. As proof of this, there have been quite a number of (often mutually exclusive) dogmas, philosophies, and prescriptive belief systems bolted onto atheism, of which the three best known are secular humanism, Marxism, and Objectivism. In addition, at least one belief system that is almost universally viewed as a religion, Buddhism, does not have any gods in its "base" form (though some versions do deify certain figures), making it atheistic by default.
- While you could alter the "definition" of religion to include atheism, the practical result is really that the term "religion" loses a lot of its value as a category, and the point would lose any power as an argument - becoming not only readily ridiculous but also self-defeating.
 Same-sex marriage
Social conservatives frequently claim that allowing same-sex marriages will "destroy" marriage... somehow. This despite the fact that those nations and states that have legalized it are doing just fine, thank you.
Another oft-repeated canard is that children are better off being raised by a mother AND a father both. To support this, they cite a study that compared children raised in two-parent families to those raised by single parents, without regard for gender. They then turn their ears off when one mentions the studies done that find children of same-sex couples are just as well-adjusted as those of opposite-sex couples.
In the UK where legalisation of same-sex marriage has been considered by the Conservative government, those in opposition repeatedly argue that its legalisation will result in the Church of England being forced to perform gay weddings despite opposing the practice. It has been pointed out to the anti-gay marriage lobby repeatedly that this will not occur; however, as they clearly have no better arguments at their disposal, it is repeated over and over again.
- The Second Law of Thermodynamics disproves evolution.
- The Second Law is frequently misinterpreted here as if to say that complicated or ordered structures were completely forbidden from forming. While thermodynamics applies to both open and closed systems, the second law states that the entropy of closed systems almost always increases. The Earth (and the evolution occurring on it) is not a closed system. Energy from the sun acts as a driving force for chemical reactions, which are a key part of biology. Thus evolution, like air conditioning and street sweeping, does not violate the Second Law.
- The fossil record gives us no transitional forms.
- Entire pages of books and websites have been dedicated to listing transitional fossils. Just as much has been written describing what a transitional form actually would be - specifically that all fossils are really transitions between something and something else. Creationists say that transitional fossils don't exist so much that this could be considered the ultimate PRATT. Their repeated use of this point in the face of evidence is an extreme form of denialism.
- Evolution theory is inseparable from Social Darwinism.
- Besides being a twisted argument from adverse consequences, this point is wrong. Charles Darwin was never involved in social Darwinism and never endorsed it, nor was the theory inspired by it. However, even if he was a proponent of social Darwinism or eugenics, and even if every evolutionary biologist since was also a fan, this fact would have absolutely no bearing on the validity of evolution. This point is like arguing that theories about gravitation are all wrong because walking off a cliff results in death: the consequences of the theory don't affect its validity. Gore's Law is quite similar.
- Evolutionism is a religion.
- There is no worship in evolution, there is no blind faith or adherence - only evidence. Religion is a quite nicely defined social construct, and no aspect of evolutionary theories fit in. At all. In short, if you were to stretch the definition of "religion" far enough to include evolution the term would cease to have any real use or proper meaning.
- The origin of life is not explained by evolution, therefore it is wrong
- The point cannot be overstated that evolution explains the origin of species and speciation, and the diversity of life as it reproduces (biogenesis). The origin of life would be explained by a different mechanism, abiogenesis, which is a separate process from evolutionary theory.
- How come there are still monkeys?
- Multiple problems exist with this one, it's mostly due to a severe misunderstanding about the nature of evolution. However, it is very common, and indeed quite a nice example to use as a branching point for dealing with these misconceptions. In short, though, "if Americans descended from Europeans, why are there still Europeans?"
- Supply side economics
- This states that if we cut taxes on the rich, they'll invest the money and it will "trickle down" to the less wealthy. Supply side economics and the Laffer Curve are sound in principle (for instance, if you have massive levels of crippling taxation and a population being fed by a black market), but have been thoroughly debunked as wishful thinking, since whenever these tax cuts have been implemented in real life, there has been no trickling down of the benefits. Yet despite this, they are held in high regard by many fiscal conservatives.
- Most purported evidence of the moon landing hoax. There are as many websites out there pointing out the blatantly obvious flaws in this conspiracy theory as there are websites trying to support the conspiracy theory. "Buzz Aldrin isn't holding a camera!" (the astronaut's cameras were attached to their chests). "There's a prop visible with 'C' written on it!" (no one labels their props like that). "The flag waves in the wind!" (grow up and read some physics). And so on and so forth.
- There's a face on Mars. This still does the rounds on conspiracy websites, blog/YouTube comments and the occasional woo-pushing documentary despite being thoroughly examined and revealed to be nothing particularly interesting. Higher resolution shots of the "face" have revealed it to be exactly what every skeptic said it was, just a mountain range with some funny shadows. It's a very interesting psychological effect known as pareidolia (indeed, this crops up every single time someone reports seeing a face in something, from Jesus on a toasted sandwich to the Devil in the smoke of the World Trade Center collapsing, yet the message still doesn't seem to get across).
