Scientist Says Most Scientific Papers Are Wrong

An anonymous reader writes "According to epidemiologist John Ioannidis, the majority of published scientific papers are wrong. If Ioannidis's own paper is right, a randomly chosen scientific paper has less than a 50% chance of being true. He also says that many papers may only be accurate measures of the prevailing bias among scientists. However, a senior editor of a scientific journal says that scientists are already aware of this: 'When I read the literature, I'm not reading it to find proof like a textbook. I'm reading to get ideas. So even if something is wrong with the paper, if they have the kernel of a novel idea, that's something to think about.'"

Great... watch the Creationist/Intelligent Design kooks run with this.

"See? Scientists don't know what they're doing! All your answers are in Teh Bile-Balllllllll! Praise JEEEEEEE-zussssssssss!"

Scientific journals? Hey, even if they can't get a paper into a scientific journal that's wrong 50% of the time....

While some scientists are claiming that intelligent design should not be taught because some religious people believe in it, other scientists are actually having difficulty determining if a particular plant is naturally occurring, whether it was created, or whether it is a cross between a naturally occurring plant and a human-created plant.

Researchers at the Centre for Ecology and Hydrology in Dorset, UK, tested the herbicide glufosinate ammonium on plants in fields previously sowed with oilseed rape modified to carry a gene conferring resistance to the herbicide. But a single charlock plant carried on growing happily, raising fears that the gene for herbicide resistance had crossed over to the charlock and created a herbicide-resistant strain.

For a theory to be "scientific," it must provide the basis for testable hypotheses.

Here are two sides of this particular debate:

1) "There is no superweed and there never has been," echoes Brian Johnson, ecological geneticist at English Nature, the nature advisers to the British government. "It's more likely that herbicide resistance in charlock has evolved naturally."

or

2) But according to some media reports, genetic testing of the purported hybrid showed that it carries the same gene as the GM crop.

Why would anyone want to close their eyes and cover their ears and say "I can't hear you - there is only evolution - there is no intelligent design - I'm not listening to you"? When actual real scientists are creating organisms which other scientists cannot distinguish from similar species found in nature?

It seems to me that lately a lot of comments on slashdot have been trying to start a witch hunt for advocates of ID. Can we please knock it off and stop screaming wolf every time some thing that is related to science is mentioned on slashdot.

You realize you're talking to zealots, right? I don't think "please" is going to cover it.

Well

Their is a 50% chance that that's not true.

Studies, Papers, Research

[fembots]

Wow, I thought Study Shows One Third of All Studies Are Nonsense is bad enough, who knows scientific papers are worse!

I patiently await the next article: "Research Shows Three-Quarters of All Researches Are Bullshit".

Re:Studies, Papers, Research

[Gabest]

Both were published by the same guy. I wonder which one is the "nonsense" then.

Therefore anything that anyone says is simply an opinion.

That's just your opinion.

Half empty, or half full?

[DrCode]

If 50% are wrong, then 50% are right. So if I write a scientific paper, the chance of it being right is 1/2. And if I write the same paper, say, 8 times, the chance of it being right at least once is 255/256.

I think I'll write that paper on statistics.

Re:Lamarck and Darwin were wrong too

If atoms aren't billard balls, how can you be sure we're monkeys?

If fish aren't landmines, how can you be sure we're really elk?

But, more to the point, should you be really drawing any conclusions?

No. Not until the smoke clears, and I can once again tell the difference between billiard balls, atoms, monkeys, landmines, and elk. And neither should you.

But what our scientist does not realize is that every time he makes a measurement, the Flying Spaghetti Monster is there changing the results with His Noodly Appendage.

Which explains why most scientific papers are wrong.
