A question about the accuracy of science

Wow! mamooth's dialogue has too many fallacies to cover them all.

You neglected to show where any of it was a fallacy. You just repeated your various unsupported conspiracy theories.

I showed the problem with Popper. Feynman, the problem is not with Feynman, but with the way deniers cherrypick him to misrepresent his views, and the way that they lack the self-awareness to understand Feynman was criticizing them. For instance, this bit of Feynman is aimed directly at denier types.

“Ordinary fools are all right; you can talk to them, and try to help them out. But pompous fools-guys who are fools and are covering it all over and impressing people as to how wonderful they are with all this hocus pocus -- THAT, I CANNOT STAND! An ordinary fool isn't a faker; an honest fool is all right. But a dishonest fool is terrible!”

That is, Feynman was a real skeptic, and he'd have had zero patience with poseur-skeptics like deniers.

The favorite denier quote from Feynman is

“It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong”


Which is stupid of them, being climate science does agree with the experiments, while those experiments contradict denier claims.

It's also an oversimplification. If an observation contradicts a theory, it doesn't mean the theory has to be completely wrong. It often means the theory only needs a bit of modification.

For example, the theory of gravity says things fall down.

I see a bird flying.

That doesn't nullify the entire theory of gravity, but denier logic says that it does.

Let's change the example. Peptic ulcers are caused by stress. The evidence was overwhelming that stress exacerbated peptic ulcers. But that dealt only with symptoms not the primary cause. Bacteria was found to be the primary cause. Was the evidence for stress wrong? Or just misguided?

I think everyone already clearly sees how global warming deniers are the equivalent to the "Ulcers are caused by stress!" diehards. New convincing evidence poured in saying they were wrong, but they refused to budge from their debunked beliefs. Some of them, doctors with practices based on treating ulcers the old way, had a financial incentive to deny the evidence. And some people just liked being contrarians, because they thought it made them look smart.

Why am I unsurprised that you didn't get the point. Consensus science determined that stress caused peptic ulcers. A team of skeptic scientists came along and demonstrated Heliobacter was the primary cause and that stress was secondary.

While global warming skeptics have not disproved CO2 as the primary cause of warming, they have certainly shown that it has been exaggerated and likely to only be a secondary factor.
 
Many people here bring up instances in which the majority opinions of scientists in a number of fields have been found incorrect. Peptic ulcers were once thought to be caused by acidic food. The universe's expansion was once thought to be slowing. These posters have used these sorts of instances to argue that we have no reason to be influenced by the fact that the vast majority of climate scientists in the world today believe that the world is still warming and that the dominant cause since at least the middle of the last century is human activity. They believe that history tells them that we have no reason to trust such opinions - that their universality simply makes them more suspect.

So, here is the question. Let us look at all the positions held by all the world's scientists since the development of the modern scientific method. If we rule to the best of our knowledge on which of those positions have since been shown to be incorrect, will we find that individual scientists or small groups of scientists have been wrong LESS often than majorities, or MORE often wrong.

The answer, of course, is that there is a very strong and direct correlation between the numbers of scientists (percent or absolute) who hold a given position and the likelihood that it is found correct - that it is not falsified. Thus the logic of rejecting the common opinion for that of the lone wolf fails its most basic test.

The Earth is getting warmer and the dominant cause is human GHG emissions and deforestation. The effects of that warming will be consequential and a committed human response is required.

More importantly... He has shown absolutely zero evidence of understanding scientific evidence.

And you're missing the point that we're the skeptics, while you deniers are only skeptic-poseurs who cling to a disproven consensus instead of looking at the data.

While global warming skeptics have not disproved CO2 as the primary cause of warming, they have certainly shown that it has been exaggerated and likely to only be a secondary factor.

And you keep illustrating that point every time you state a conspiracy theory as if it were a fact.

Ian, you're just a common conspiracy nutter with delusions of adequacy. And your reaction to those who point that out is the same as any other conspiracy nutter.

the only conspiracy is that CO2 is dangerous. Promoted by warmers with no evidence. PERIOD!

I see you have retreated into fact free and idea free ranting and poo flinging again.

Up your game.
 
The earth is getting warmer (or colder)

So what? That's what the earth has done

Domant cause humans

So in your world you want to exterminate us all? You go first.


The effects of that warming (or cooling) will be consequential


Again so what, it would happen anyways

human response is required.


Why? So it makes you feel good, when we all die anyway when yellow stone explode or a mile wide asteroid slams into us?

The problem is economics. When you have weather problems that are extreme it costs big bucks to make everything normal again. Drought in the desert southwest, extreme cold/rain in the northeast. If we did worked to make the air clean/cleaner again it could go along way to normalize weather patterns or at least make breathing easier.

I'm doing my part with two electric vehicles, one charging only from the sun. What are you doing?

The arrow of time precludes going back to the good ol' days.

I am all for cleaning up the air but your personal choices are not available for most of us. Perhaps some of the money being wasted on the bureaucracy of clime change could be better spent on other more useful projects.

The development of technology to replace fossil fuels will come. But just dumping money into old technology won't work. There are reasons why we got rid of windmills, and solar panels aren't much better.

Dumping gobs of money into physically unrealistic schemes only makes the charlatans rich.

Lemme help ya out here. In theory -- It only takes ONE scientist to bring down an entire highrise tower of misconception or error. That's just how it works. YOU DEFEND positions. You debate the methodology and you analyze the data. He/She/It who presents the most UNIMPEACHABLE argument wins.

BTW -- doesn't mean that the person WINNING that round HAS to offer another valid explanation. It can be done by REPLACING that explanation --- or finding that the initial idiot can't DEFEND his assertion.. Equally acceptable outcomes.

BTW #2 ---- If you REFUSE to answer the questions, duck the debates or HIDE YOUR DATA --- you automatically lose.. You also lose immediately upon any appeal to consensus or authority... :biggrin:

Has NOTHING to do voting, polls, or the size of the team.. It's really "an individual sport".. Got it? Great....
 
"Science is science but theories are funded".. The surprisingly readable book "Neanderthal Man in Search of the lost Genome" by Swedish PHD, Svante Paabo (2010) inadvertently offers insight into the sleazy world of modern science and scientists. Guess what, they cheat, steal, offer fraudulent data in exchange for money and fame and in short they are just like us common folks except a bit less concerned with honesty. If you translate the information offered by Paabo to the lavishly funded "global warming theory" there is no question that the scientific community would be the hired gun of any administration that funded the "research". Why would federal drones with oversight responsibility for global warming data question the data as long as the data coincides with the theory the federal government is paying for?
 
Ah, philosophy of science questions.

First rule of thumb. If someone quotes Popper or Feymann non-ironically to back their position, you're almost certainly looking at a pseudoscience crank, as that's a favored tactic of those who have no evidence for their own position.

Popper had some problems. He said that falsifiability defines science. To show the problems with that, consider ...

"Vaccines do not cause autism."

Now show what could falsify that.

It's pretty much impossible to absolutely falsify that statement with any realistic data. Yet it's still clearly science.

Real science is more defined by coherence, consilience, and consensus.

Coherence. Internally consistent. Real climate science is coherent. Denialism cobbles a dozen conflicting conspiracy theories together.

Consilience. Multiple independent evidence streams converging on the same result. Real climate science has that, which is why it's so peculiar that deniers think obsessively nitpicking a single minor point means anything.

Consensus. Scientists share a common set of theories, observations and models, and can talk to each other, find flaws in any points, and work forward from it. Real climate science has that. Denialism has no consensus of its own, just a religious belief that requires hating the opposition.
Prove it, without quoting Rush Limbaugh

Actually plants require less water when ambient air concentrations of CO2 are higher, thus fighting desertification.

I miss the days when weather used to be gentle. When was that again?

Drought in the desert southwest, extreme cold/rain in the northeast.

Drought in the desert? I blame oil. Durr.

Popper had some problems. He said that falsifiability defines science. To show the problems with that, consider ...

"Vaccines do not cause autism."

Now show what could falsify that..
Anything that would establish a clear link and mechanism for a vaccine causing autism. If a vaccine did cause autism (they don't) then it would be possible to show that it did, and that would falsify the claim that the vaccines do not cause autism.

That's a bad example, though, as "vaccines do not cause autism" isn't a theory in itself, but a rejection of the theory that vaccines do cause autism (because there is zero support for that claim).
 
Popper defined the modern scientific method - based on falsification. It is current and if a research scientist (at least, in the pure sciences) wants his/her peers to approve a publication (in a scientific journal), that scientist damn well better have paid attention to Popper.

For those in the market for snake oil, rather than science, believe the hack who is selling it.
 
Global warming denialism, being totally unfalsifiable, would be defined by Popper as snake oil.

In contrast, global warming theory is easily falsifiable in many ways, and is thus defined by Popper as real science.

However, Popper is still kind of snake oil himself. Some things in science are too fuzzy to be absolutely provable or disprovable by any realistic means. As Feynman said, sort of refuting Popper, “If you thought that science was certain - well, that is just an error on your part.”
