Can Science Ever Be "Settled?"
StartsWithABang writes "From physics to biology, from health and medicine to environmental and climate science, you'll frequently hear claims that the science is settled. Meanwhile, those who disagree with the conclusions will clamor that science can never be 'settled,' and then the name-calling from 'alarmist' to 'denier' ensues.
But can science legitimately ever be considered settled, and if so, what does that mean? We consider gravitation, evolution, the Big Bang, germ theory, and global warming in an effort to find out."
all attempts to disprove it have failed and until evidence can be presented to disprove or bring the results into question it is settled
it doesn't mean "this is doctrine never challenge it" it means challenge it knowing that it has been challenged before and the theory has held
Newton's laws have been pretty much settled. Einstein found a way to get more precision under certain circumstances, but Newton is good enough most of the time.
That's not a summary, that's a click bait.
Fuck systemd. Fuck Redhat. Fuck Soylent, too. Wait, scratch the last one.
It's a process.
"evolutionary criticism . . . is completely forbidden in US schools."
Well, unless you go to school in one of those states where the school boards also don't think children should be trusted to learn about puberty, carbon dating, and history that wasn't vetted by the Club for Growth and the Daughters of Confederate Heroes.
No amount of experimentation can ever prove me right; a single experiment can prove me wrong.
-- Albert Einstein
First class example is that evolutionary criticism (missing intermediate species or disputed claims of finding them, Darwin's doubled-down denial of genetics, etc) is completely forbidden in US schools.
They're not "completely forbidden", and they're certainly not forbidden in private schools. What is forbidden is using petty nitpicking of details, which are at best only marginally relevant to the validity of evolutionary theory, to advance religious doctrine, which is the only reason these issues are ever raised in the first place. If you want religion taught in public schools, move to Iran or some other country where superstition is mandated by law.
For well over a thousand years Aristotle's work in the physical sciences (including zooology) was considered settled... until people started testing his theories
We called that period the "Enlightenment"
Not a result. Thus, attempts to claim that the science is settled are attempts to shut down the scientific process.
If the results of the scientific process are good, they're reproducible, and there's no point in trying to build up a religious dogma of belief on something that simply is.
Questioning the "settled science" is science. Shut it down at the cost of shutting down science.
Stalinism
Is it petty of me to wish that people who accuse their political opponents of being Nazis, Communists, etc., could live for a little while in the world of their paranoid fantasies? If they survived the experience, a month in the actual USSR under Stalin, for example, might give them much more perspective.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
Or maybe Evolution is just supported by so much overwhelming evidence that 99%+ of scientists accept it as the best theory. Most of the scientific discussions around Evolution are centered around how we dot the i's and cross the t's, not whether Evolution is a better theory than "last Tuesday God said 'abracadabra' and the Universe was formed as is with its 'history' as an illusion."
In a school's science class, students should learn what the prevailing scientific theories are. They should learn why those theories are the prevailing ones. However, school is not the place for students - who are just learning the material and who will have a highly incomplete knowledge of the subject - to make a determination of which theory is the "right" one.
Whenever someone says "we need to teach the weaknesses of Evolution", what they really mean is "I would like schools to teach Creationism, but that was struck down by the Supreme Court... as was Intelligent Design... so maybe if we sow enough doubt about Evolution in the students, they'll grow up believing that God created it all 10,000 years ago."

Yes, it's petty, but I do it too, all the time. For instance, just last week I was thinking about how helpful a smallpox epidemic would be in demonstrating why we have vaccines. Likewise, I'd like to see the American Christians who claim to be persecuted spend some time in Saudi Arabia or China so they could understand the true meaning of persecution. I don't actually think any of these people deserve this, but I can't think of anything else that would convince them of how stupid they sound.
I really liked the way one person put it to me a while back. Some people used to have some idea the earth was flat, but then some people realized that wasn't true and said it was a sphere. Well, that was clearly wrong too but a sphere is a lot closer to the truth than flat; treating wrongness as a boolean would just label them both wrong but, one is clearly a lot less wrong than the other.
So to some degree, it was settled...possibilities were excluded. Then, well its clearly not a sphere, it bulges in the middle, I have heard "slightly pear shaped" is a good description.... then you have the satellites that have precisely measured variations in gravitational field...they have an even more complex picture.
Whether it is settled or not depends on to what degree you need the answers.
"I opened my eyes, and everything went dark again"
Absolutely. Settled doesn't mean True - science is unconcerned with Truth, perhaps even actively opposed to it. Because there is no theoretical way to distinguish between Truth and an extremely accurate and reliable misunderstanding. Accepting something as Truth denies the ability to challenge it - and those challenges are the very essence of science.
Settled means it has so thoroughly withstood all challenges that nobody much even bothers to challenge it anymore, and you'd better have some really solid new evidence to back any new challenge or expect to be laughed off the stage.
This is why the vast majority of anti-AGW positions are considered so ridiculous: The studies they're based on are almost universally either so laughably bad as to be obvious paid "science" propaganda, or are so badly misrepresented that the researchers themselves object to the claims being made by the pundits. Meanwhile the handful of potentially legitimate challenges are largely ignored by the media, presumably because they're either so esoteric they can't be expressed in sound bytes, or so outlandish that only other scientists could take them seriously. Unlike the propaganda being fed to the public, the larger climatology community generally treats those challenges with polite skepticism and constructive criticism because they are at least plausible, even if they need a *lot* more supporting evidence before they could be considered viable alternative explanations.

There's also a difference between observations and theories. For instance, gravity is pretty much "settled". However, it's an observation. We always see that objects are attracted to other massive objects; every time we throw something in the air, it falls to the ground. At this point, it'd be stupid to say that gravity doesn't exist.
However, whyare objects with mass attracted to other objects with mass? That isn't very well understood. We have a theory that describes the relationship (the universal gravitation theory), in a simple equation that tells you the gravitational force given two objects' masses and distance apart. But why is it so? According to Einstein's theories, it's because the spacetime continuum is warped by mass like a rubber sheet, and gravity is just a side-effect of this. According to Quantum Mechanics, particles called gravitons are responsible somehow.
So we can debate all day about what exactly causes gravity, but the existence of gravity itself is really undeniable at this point.
Similarly, with evolution, the age of the earth, etc., the theories might be somewhat debatable (but not nearly as much as gravitational theories), the evidence that led to those theories' creation is pretty undeniable at this point, namely fossils and other geological evidence. Claiming the earth is 6500 years old when there's enormous evidence contradicting that claim is just stupid.
First class example is that evolutionary criticism (missing intermediate species or disputed claims of finding them, Darwin's doubled-down denial of genetics, etc) is completely forbidden in US schools.
They're not "completely forbidden", and they're certainly not forbidden in private schools. What is forbidden is using petty nitpicking of details, which are at best only marginally relevant to the validity of evolutionary theory, to advance religious doctrine, which is the only reason these issues are ever raised in the first place. If you want religion taught in public schools, move to Iran or some other country where superstition is mandated by law.
The idea that questions about evolution are only raised to advanced religious doctrine is a bit of a religious doctrine in and of itself. Literally the moment that anybody questions anything main stream the immediate response is that those people must be backwoods religious extremists. You see it EVERYWHERE. Somebody raises questions about monetary policy and excessive spending and people immediately go straight to conservative therefore religious. Anybody had the gall to suggest that it was possible for some people to be predisposed to have a negative reaction to something in a vaccine you'd immediately hear "right-wing-religious-nut-job" thrown into the conversation somewhere.
At some point public branding began happening that if you ever dare to discuss an issue, point out flaws, or raise dare I say "valid" discussion points that your question was invalid simply by invoking "right-wing-religious-nut-job" in the conversation.
The sheer fact that so many people immediately use that as a go-to rather that even thinking of defending any questions would seem to indicate that those people feel their own doctrine is being questioned, which makes the idea of those people calling others extremist nut jobs kind've ironic.
One of my all time favorite quotes:
"The test of first rate intelligence is to hold two opposing ideas in the mind at the same time and still retain the ability to function." - Dwight Whitney Morrow
There's a lot of people who believe themselves to be intelligent who cannot allow themselves to try to see things from another angle. Nobody holds a viewpoint strongly without having a good reason for doing so. If more people recognized that and tried to understand the other side you'd see a lot less vocal hostility.
Odds are very good that if you feel strongly about something there are a whole lot of times where you're right and a whole lot of times where you're also wrong.
"Don't teach a man to fish, feed yourself. He's a grown man. Fishing's not that hard." - Ron Swanson
My interpretation is that there is enough confidence from the scientific community for anyone who is not a scientist researching the topic to accept the current understanding as fact. It doesn't mean they should think it is a fact, just that they should lead their life and form opinions based on the assumption that it is a fact.
Research should of course continue, probably until the end of time, but at a certain point the general population should no longer question the findings. They simply are not trained enough to form an opinion that differs from the general consensus.

In the past 30 years Darwinists suppressed information about inheritance of acquired traits. The Lamarckian-looking genetics that explain this are now FINALLY being accepted as science and are called, as a group of phenomenon, "epigenetics".
This simply demonstrates your ignorance of the field. Epigenetics is far more fundamental and complicated than Lamarckian inheritance - it's a basic mechanism of genetic regulation in all multicellular organisms. This wasn't even remotely controversial 15 years ago, when I started studying biology; any freshman biology course would cover the subject. It still isn't terribly well understood, but what can you expect when we still don't know the function of half of our genes?
What was genuinely controversial was the extent to which epigenetic regulation affected germ cells and was therefore heritable. It was not controversial because "Darwinists" (whatever that means) tried to suppress information, it was because none of the loudest proponents of the theory had found molecular evidence to support it. This is now slowly changing, as biologists are realizing (yet again) that genetic regulation is even more complex than they imagined.
In any case, none of the new information contradicts modern evolutionary theory; likewise, it does not have any relevance to the issue of whether modern life forms were designed or evolved. It also doesn't overturn the "central dogma" of molecular biology or prove that Lamarck's overall hypothesis was correct. We still have every reason to continue to believe that the unmodified genome is the most important carrier of genetic information and determinant of phenotype, and the extent to which epigenetics is heritable is still an unsolved debate. That makes it a fascinating target for more research, and I'm sure there will be more startling discoveries (and perhaps Nobel prizes) in the near future. I'm also very confident that any new discoveries will be made by actual scientists doing actual research, not theologians.
I have no idea how monetary policy or vaccine reactions are relevant to this debate, or what they have to do with religion. Nor are politics particularly relevant, since you can find scientists of all ideologies working productively without making extravagant pseudo-scientific claims.
As a biologist, I do know that nearly every single objection I have ever encountered to evolution - and, in particular, common descent, especially as applied to humans and apes - has ultimately been driven by a religious viewpoint, usually a belief in the literal truth of the Old Testament. (I was going to say that the panspermia advocates were the biggest exception, but even they aren't really arguing with the fact of evolution, but the origin of life, which is a different matter.) This goes doubly for the age of the earth, which is even less controversial than common descent. The creationists are also almost uniformly not practicing scientists (or even trained as biologists, in all but a handful of cases); I have yet to meet any biologist who continues to be productive while completely ignoring 150 years of scientific evidence. Conversely, I've known a decent number of biologists who were religious, but did not see the need to distort every scientific finding to fit into their theological worldview. (Francis Collins and Ken Miller are two of the most famous examples, but I've never met them, although I think I used Miller's textbook in high school.) In fact, the one who found "intelligent design" the most infuriating was a conservative Catholic.
In summary: why shouldn't I assume that creationists are religious? You've given me absolutely no reason to think otherwise.
My money is being used to expose children to views I don't agree with.
My money is being used to enforce laws I disagree with, and buy weapons I don't approve of. It's called representative democracy; deal with it, or move somewhere else. We do, however, have a specific clause in our constitution about establishment of religion, and the courts have decided that teaching religion in taxpayer-funded schools is included in this prohibition. (This does not equate to disallowing all criticism of science; you are welcome to spout any nonsense you wish, as long as you do not expect the government to pay for it.) If you're unhappy with that, work on getting the 1st Amendment repealed, or move to another country. I'm sure you won't find much support for teaching evolution in, say, Somalia. (But they're probably not going to be wild about your religion either.)
How is asking critical questions about view points being pushed onto children with my money establishing religion?
Stop playing dumb. We all know that the only reason these "critical questions" (which never come from actual scientists) are ever introduced into a classroom is to promote a religious alternative. Pretending otherwise is just disingenuous and insulting. At least Ken Ham has the honesty to admit this is his goal.
Natural selection comprises two types: ecological and sexual. Both work the same way: An individual passes its genes down more successfully by surviving longer and in good enough health to produce more offspring.
Ecological selection is what we normally think of as "natural" selection (survival of the fittest). In this case the "selection pressure" is determined by fitness for the environment where one lives. In sexual selection, the selection pressure comes from other members of the species.
Though they work in similar ways, the two may often be at odds with each other. The classic example would be the peacock's tail, which is "costly" to produce and maintain, and actually makes the bird less well adapted to the environment -- dragging all that plumage around slows him down, making him more susceptible to predation. The only useful purpose it serves is to attract peahens. The peahen's preference for a large, showy tail creates a positive feedback, pushing the peacock's tail to its maximum "survivable" size.
