Is the scientific method seriously flawed?

By | December 12, 2010, 11:31 AM PST

The scientific method—the use of experiments to observe and test hypotheses may be under fire due to the decline effect. This decline effect dictates that experiments used to find the truth often lose their luster and ability to be replicated over time.

A New Yorker report outlines the conundrum:

The test of replicability, as it’s known, is the foundation of modern research. It’s a safeguard for the creep of subjectivity. But now all sorts of well-established, multiply confirmed findings have started to look increasingly uncertain. It’s as if our facts are losing their truth. This phenomenon doesn’t yet have an official name, but it’s occurring across a wide range of fields, from psychology to ecology.

In medicine, the effectiveness of antipsychotic meds are called into question as are cardiac stents and Vitamin E. Facts are eroding quickly. One analysis will show that the efficacy of antidepressants has gone down as much as threefold in recent decades.

According to the New Yorker report—read in full via Amazon’s Kindle—numerous fields are suffering from the decline effect. The New Yorker highlights the following issues with the scientific method.

  • Replicating an experiment and getting the exact same findings is difficult. Why? Regression to the mean. As an experiment is repeated statistical flukes get tossed out.
  • The peer review process is flawed. Peer review is ultimately tilted to positive results.
  • Publication bias. Journals and scientists aim for being statistically significant and this leads everyone aiming for positive results. We don’t want to see a null result. Researchers are “significance chasing,” or interpreting data so it passes the statistical test of significance.
  • Money. For instance, pharmaceutical companies have little interest in publishing results that aren’t favorable. Validating a hypothesis is all the more gratifying if there’s financial gain to be made.
  • Selective reporting. The New Yorker notes that selective reporting isn’t fraud, it’s just that researchers may make subtle omissions and misperceptions as they try and explain their results. One example cited was the testing of acupuncture. In the West, acupuncture effectiveness is questioned. Not surprisingly, studies so acupuncture’s effectiveness isn’t all that great. In the East, the effectiveness is deemed higher. Scientists look for ways to confirm their preferred hypothesis.

Add it up and researchers are seeing what they want to see. The New Yorker take makes sense—humans hate being wrong.

So what’s the fix? A few scientists in the New Yorker argue that more rigorous data collection can be a fix. Experiments are often poorly designed. In addition, an open source database where researchers could detail what data they were collecting and goals could head off the decline effect—at least a bit.

Wow.
Junk science cannot hold up to peer review or the scientific method so they attack both as flawed.

The flaws that are pointed out in the article involve the implementation of the scientific method. Not the method itself.

When alleged scientists fail to follow proper procedures their tests cannot be replicated. Proof that there is an inherit strength to the process.

RE: Is the scientific method seriously flawed?
The flaw I believe is in human nature, not the scientific method. The flaws mentioned are a result of humans wanting more out of something than the circumstances warrant. As long as we keep things moving forward though we should eventually zero in on reality.

HI, not to be contrary but I'd like to point out that peer review is merely the first step on the road to scientific validity. It's like a spellchecker for science weeding out the obviously flawed stuff so others don't have to waste their time on it. Once a paper has passed peer review it gets published and is open to the support and/or criticism of the broader scientific community.

Thanks river..
I understand peer review is just part of the process, but these guys are attacking the parts of the process so I kept them separate for the discussion.

In bygone years a theory had to be replicated multiple times by often competing laboratories. In many cases labs wanted to prove the other guys wrong to show them up, but if they proved the theory and replicated the results they were adult enough to admit it and advance science for the sake of mankind.

What we see so much of today is people duplicating their own work and declaring a scientific breakthrough. Then when someone else try to replicate their experiment and fails the confirming scientific group is attacked in the press and in scientific papers. Instead of advancing the discussion they try to stifle it.

You are correct that human nature, or more precisely human ego, has corrupted the process.

Where would we be if zealots defended the junk science about cold fusion in the 1980s instead of using legitimate science to confirm or refute the claims?

Scientific Method exposes flawed research, ergo the Scientific
Method must be wrong. Now, that's logic at it's finest. Is it no wonder
that people are skeptical of politicized "scientific" issues?

Humans are seriously "flawed"
Human nature, with attachment to specific outcomes, is our greatest enemy, not the scientific method. This can manifest as enterprises skewing data, process, and conclusions to paint a new patent drug favorably. It can appear as Group Think where anyone who dares to propose that the common wisdom is incorrect, automatically becomes a quack, and is discredited. It can appear in quelling research into areas where we already "know" the answer.

Blaming the scientific process for all its "shortcomings" is like blaming seat belts for being ineffective when they are not used.

riverat1 is right
The failure to follow the scientific method does not invalidate the
method. It invalidates the researchers.

In several of the disciplines mentioned in the article, the holiness of
the theory trumps contrary data.

RE: Is the scientific method seriously flawed?
The researcher omitted a vitally relevant source of many false research reports: politics. In the acupuncture example, it is in the best interests of the AMA to publish research findings that negate the value of acupuncture, just as they did historically with so many other health approaches, e.g. labeling Echinacea as "snake oil" and publishing ads promoting tobacco smoking in their journals. Political agenda is a potent force behind the publishing of spurious research conclusions.

RE: Is the scientific method seriously flawed?
What silliness. Far from condemning the scientific method, the
so-called "decline effect" confirms it. Junk science is always with
us, whether it stems from "selective reporting," flawed "peer
review," or "publication bias." Scientists are human, after all. The
"test of replicability" counters human bias, poor experiment
design, lack of rigorous data collection, etc. Continued repetition
of experiments eventually winnows out junk science. Our facts
are not "losing their truth." Rather, it's simply being
demonstrated that the facts in question are not, in fact, facts.
That's the scientific method at work. Q.E.D.

RE: Is the scientific method seriously flawed?
Unfortunately the scientific method is utilized less and less in order to avoid accountability and to make room for more money to flow in from grants and the like. The scientific method isn't flawed, it is being abandoned so researchers and "scientists" can make outrageous claims, provide no evidence and secure more funding and fame.

if nothing else, the fact that this tripe is being touted on this site brings at least the authors (if not those who should be screening articles and story ideas) into question - along with much of the material the authors have brought forth previously.

I'm with the rest of the crowd on this one
If folks WERE following the 'scientific method' then this would not be an issue in the first place.

JimRicker states it well. Too much of "science" is about fund raising. How many so-called science issues start out, "You're all going to die if you don't fund [fill in the blank] research." I put forth the IPCC as a classic example of rent seeking. Look at Cancun this week. What's the big result? Why, scalping the American taxpayers for 100 BILLION dollars a year, that's what.

I love science. Let's try doing some.

RE: Is the scientific method seriously flawed?
The problem is that "information" is not "knowledge". The New Yorker wrote, "It's as if our facts are loosing their truth." What is more accurate to say is that the truth is getting obscured by a deluge of information.

We live in a world of near infinite information, but the production of knowledge and the identification of truth haven't scaled up nearly as fast as the production of information. What's more, the distribution of information is skewed to the more sensational, since us humans enjoy novelty. The net result is an information space which obscures the value of the scientific method.

In other words, articles with the title "Is the scientific method seriously flawed?" are favored as a novel bit of information rather than articles which might educate more to the truth.

Correct the title! S/B: Scientists use flawed methods in their science.
The argument pursued in the article concerned the methods used by "scientists" and the problem is not at all the "scientific method".

It is the "agendized" science that is at fault, and the writer mentioned that a few times, and failed to indicate where the scientific method is/was wrong.

The New Yorker is NOT science magazine or journal
So any stories in there about science should be taken with a HUGE parking lot of salt.

The scientific method works. But it only works where something can be DISproven. If it's not possible to prove something wrong, then it's not subject confirmation by the scientific method. Thomas Edison's teams were well known for doing experiments that showed lots of ways things couldn't be done.

Regression to a mean is not the decline effect. The problem with many experiments is that the report is made based on a limited number of tests where the results are too few to be statistically significant. In those cases, outliers are still the drivers and early analysis and conclusions will be flawed; but not the method itself.

Peer review, especially for science and engineering, is most cost effectively done at the university level. Nothing like 20 colleges sticking 50 or more undergrads on evalutating a hypothesis to show whether it's any good or not.

All good ... and logical comment ...
I see it a bit like the legal system ... Court lawyers might use tricks
of law to mitigate 'unfortunates' in fact ... like a company-
employed scientist ...
Above them are the power-mongers ... the Judges ... who define
.. and defend .. "Law" ...
Perhaps more scientists should contemplate climbing higher in
their chosen field ... and endear more intra-professional respect
.. and integrity ..
As a matter of ethics ... the method isn't flawed ... but some of it's
users' might be .... The supposed goal is "The greater good" ..
which .. of course .. might conflict with ego ...

RE: Is the scientific method seriously flawed?
What you point out are not flaws in the scientific approach but bad science, small and narrow samples, and self-serving or wishful-thinking bias. The last thing we need are average joes running around saying "the scientific method is wrong - we can believe whatever we want!"; we have too much of that already. Skepticism is good only when accompanied by an honest understanding of different aspects of the particular issue at hand, but otherwise is useless or harmful.

RE: Is the scientific method seriously flawed?
Is your process for choosing the titles of your articles seriously flawed?

* Choosing a good title is difficult. Why be diligent when you can just be clever?

* The peer review process is flawed. If you veto my jazzy title, I'm gonna veto yours.

* Publication bias. Writers aim for catchy titles that will grab eyeballs, the facts be damned.

* Money. Advertisers like eyeballs too.

* Selective reporting. Jump on a provocative statement and run with it as your title. Never mind that the vast majority of experts in the field think the statement is utter nonsense. Pose your title as a question: that way, you can always backpedal by saying, "Hey, we never CLAIMED this was true -- we just posed the question."

"So what?s the fix?"
You wanna know what the fix is? Have *REAL* scientists perform *REAL* science...not this pseudo-crap sensationalistic "science" that is only designed to get headlines.
Get the reporters out of the laboratory to allow the real scientists enough time to get actual results. Look at what happened with the fiasco of Cold Fusion a dozen and a half or so years ago.

RE: Is the scientific method seriously flawed?
One thing missing from these replies so far is the "grease" that allows the scientific method to work, the disinterested observer. If your results are not 'significant' redesign your experiment and rerun, don't massage the data to make it something it isn't. Ignoring results that conflict with your goals isn't science it's salesmanship.

One way to address the corporate bias, is for the federal Government to require that ALL research results be published, no matter who pays for it. No ditched studies. JM2C

Wow! You guys are getting good!
I'm going to apply for a grant to study how best to elicit comments. I'll pay off my house with the money, live for a year in the basement surfing the web for legitimate research supporting whatever angle I like best (Politics!), ignore whatever evidence I don't like (because it could negatively impact my case, and, thus, my grant money), set up a web-site to publish some provocatively worded articles (Osama beats his wife! Palin beats her husband!), enlist my network to like them, maybe even comment, add a bunch of comments to other blogs about how stupid my critics are for not accepting the obvious truth the blogs evolved spontaneously with no thought or plan behind them (shouldn't be too hard to prove), write up a paper on the psychology of serial commenters, and I'm on my way... Speaking engagements, people citing my 'ground-breaking research' in scholarly papers, interviews. Hey! If I can tie my stuff into the crisis du jour, I could end up in office!

Hmmm... what crisis... Global warming's been done to death. Healthcare? Passe. OH! I know! Ozone from hybrid car electric motors is giving us cancer, but commenters are drowning out the responsible reporting of legitimate media outlets!

And I can prove it, too!

You can all make donations to my paypal account.

Now that's what I call the scientific method!

RE: Is the scientific method seriously flawed?
Not only is the scientific method not seriously flawed, it ain't flawed at all. It's pretty straight forward.
1.Theory - If ..xyz...Then.....abc
2. Design an experiment to prove or disprove: if xyz then abc.
3. Execute the experiment and observe the results.

Example:
1. If I am holding a container of milk in my hand and I open my hand, releasing my grip on the container of milk, it will fall to the floor, to the great delight of my cat.
2. I will obtain a container of milk and a cat and a slow-motion camera to record the results of this earth shaking experiment.
3. With my new found friend watching me with great interest, I open my hand, releasing my container of milk and observe the results.
Observation #1 The container of milk falls earthward rather than floating off into the distance. Thus I have proved Sir Isaac Newtons theory of Gravity, even though I didn't get hit on the head with an apple. I have also simultaneously disproved Sarah Palin's theory of everything.
Observation #2 I forgot to look where the cat was before releasing the container of milk, which strikes the cat on the head before spilling on the floor sending the cat running.
Observation #3 The cat has returned and seems somewhat happy as it laps up the milk.
Observation #4 (unintended observation by my wife)...So, where did this cat come from, why is it soaking wet and why is there milk all over the floor?
Observation #5 I can still run faster than my wife.
That boys and girls is the scientific method. Whether or not I publish the results for all to see or make big bucks (only publishing after patenting my new method for bathing and feeding cats simultaneously), really has no bearing on whether or not this is the scientific method. I now invite all you to go out, obtain a cat and a container of milk and replicate the results of my experiment. Make sure your wife isn't watching. Ladies don't worry if hubby is watching because he doesn't really care what happens to the cat or the milk, as long as he doesn't have to clean up after your experiment. Try to aim for a section of the floor where the cat isn't standing.

RE: Is the scientific method seriously flawed?
When science was the pastime of the rich gentlemen they had perhaps less interest in the results of experiments, no money would trade hands and their reputations were maintained by their secretish societies. If you did not get the recognition you craved you just started another society. Thus you could experient to either prove or disprove your theory and either way it was your rigorous attention to the method of data collection that earned merit. Now the only results that brings home grants and private money are positive ones.Sooooooooo. . . .

Alternative?
So, people claiming to use the scientific method sometimes achieve different results than other people claiming to use the scientific method.
Does the New Yorker have any suggestions for repair or replacement of the scientific method? Popular vote, perhaps? Or submit all questions to Professor Trelawny?
Just comparing how I'm typing this, compared to how I would have had to submit text for publication a few decades ago, speaks to the success of the scientific method.
Or maybe it just doesn't apply well to the two disciplines mentioned: ecology, where scientists hope to improve the reactions within the 200 million+ cubic miles that make up our environment (That number just represents the ocean and lower atmosphere. I guess we should also add the earth's interior and solar & lunar influences.), and psychology, a system as prone to being influenced by its observers and any electron Mr Heisenberg ever met.

There is absolutely NOTHING wrong with the scientific method!
However, people are flawed, and the use of REDUCTIONIST experimentation is limited.

It's been known for a long time that the only way major progress happens in a scientific field is by having elder scientists die or retire.

"As an experiment is repeated statistical flukes get tossed out."
THIS IS NOT using science--all the really cool stuff is in those statistical "flukes!"

"The peer review process is flawed. Peer review is ultimately tilted to positive results."

The peer review process has ALWAYS been flawed, but again, it is NOT part of the scientific method, it's part of the reporting process--little original work which raises questions manages to make it trough the review process, which rather than favoring positive results, favors results which agree with previous study!

"Publication bias. Journals and scientists aim for being statistically significant and this leads everyone aiming for positive results. We don?t want to see a null result. Researchers are ?significance chasing,? or interpreting data so it passes the statistical test of significance."

Again, NOT part of the methodology, but part of the reporting process.

"Money. For instance, pharmaceutical companies have little interest in publishing results that aren?t favorable. Validating a hypothesis is all the more gratifying if there?s financial gain to be made."

Again, NOT a problem with the method, but external forces affecting what gets studied, how it gets studied and whether it gets published!

"Selective reporting. The New Yorker notes that selective reporting isn?t fraud, it?s just that researchers may make subtle omissions and misperceptions as they try and explain their results. Scientists look for ways to confirm their preferred hypothesis."

AGAIN! it's not the METHOD that's flawed,it's how it gets twisted in use. Scientists who come up with null inconclusive or heaven forbid--contradictory results don't get funding.


NOTHING IS WRONG WITH THE METHOD.

HOW it is applied, what hypotheses are tested, how well studies are designed, sample sizes, reporting are all HUMAN problems related to HUMANS working to push forward an agenda rather than to explore and find out about the Universe.

This is "Science" the religion, not the scientific method.

Throwing out statistical anomalies without finding the explanation for them, is BAD research. But it says NOTHING about the scientific method, since it is an aberration of the method.

Directed research on which millions of dollars depend is almost certain to lead to flawed results--if your results don't support the profitable outcome, you will not get funded.

The acceptance of extremely small sample studies is a major flaw in how science is conducted--this is especially true in biology, since have organism reacts slightly differently to each stimulus.

Reductionist science (limiting all but one factor,) can only take you so far--nearly everything is synergistic and thus varies according to multiple conditions.

Teaching is a problem too--nearly everyone "knows" that "All objects fall at the same speed regardless of mass in a vacuum."

But it is only APPARENTLY true when the mass difference between the "falling" bodies is minute compared to the body they are attracted to--once the masses of all three objects become similar, so that the differences become minute between the attracted bodies, they will move at different speeds because G is a function of the masses of both bodies.

A feather and a hammer fall at so nearly the same speed the difference is negligible. But compare a feather and a mass nearly the same as the attracting body (say a really large asteroid and the moon,) and the rates will become measurably different.

We've been presented with an image of the "pure" scientist over the past century or so, who, like the "infallible" doctor, and the "independent" American, doesn't exist.

History is filled with "science" which was held as "fact" long after it was proven to be incorrect, and there will always be differences of scale--the Universe does not behave the same at all scales! What happens at the quantum level is, so far as we know, not representative of things happening at human or galactic scale.

The financial and social issues surrounding our use of science is as flawed as any other human endeavor. But the method is solid, and because it includes explicitly the concept that previous reasoning may be flawed and thus can be changed, makes it superior to any previous methodology we have used to understand the Universe.

"Science" is not the "scientific method," but an aberration of the results of the method to reflect the human need for stability. Humans would rather "know" something to be so, and be wrong, than to have to live with the uncertainty of the unknown.

"Science" is no more the scientific method, than "Religion" is the same as theology.

However flawed our execution, the scientific method, which is purely an extension of "common sense," is sound.
