Just Plain, Or Not So Plain, Ignorant

I was reading Yuval Harari’s “Sapiens” last night and came upon this. (Despite my occasional cavils, this is a brilliant book, highly recommended.)

The Scientific Revolution has not been a revolution of knowledge. It has been above all a revolution of ignorance.

Shortly after came this:

Premodern traditions of knowledge such as Islam, Christianity, Buddhism and Confucianism asserted that everything that is important to know about the world was already known. The great gods, or the one almighty God, or the wise people of the past possessed all-encompassing wisdom, which they revealed to us in scriptures and oral traditions. Ordinary mortals gained knowledge by delving into ancient texts and traditions  and understanding them properly. It was inconceivable that the Bible, the Qur’an or the Vedas were missing out on a crucial secret of the universe – a secret that might yet be discovered by flesh-and-blood creatures.

If something couldn’t be found in scriptures then it was, by definition, trivial.

So, I have to ask: has anything changed? The power of religions is based upon their traditions and scriptures, so they reinforce that power every chance they get. They weave that power into our cultures and politics to sustain it.

And, it is clear that very, very, very important things were left out of scriptures as they were unknown at the time of their writing.

So, has anything changed?

And I Can’t Stands No More!

Okay, this is getting seriously out of whack. The Ancient Aliens crew have been selling snake oil for years now and have created a great deal of content that is a lark. They fast cut from topic to topic spinning a narrative that aliens have visited us and are responsible for, well, most of human evolution, according to them.

Last night I viewed an episode that went way too far. Here is their website’s blurb for the episode:
The Science Wars
TV-PG
Nearly every year archaeologists and anthropologists make discoveries that require revisions to our history books. But there are numerous artifacts that are outright ignored because they don’t fit into the accepted scientific paradigm. Could clues about our extraterrestrial origins be hidden in these discarded pieces of our past? Shocking evidence has recently been revealed that challenges the accepted dating of the Great Pyramid. An ancient hammer found in Texas that dates back 140 million years is ignored by mainstream archaeologists. And unexplainable elongated skulls have been found on nearly every continent of the world that science refuses to test. Could we be on the brink of scientific discoveries that the academic community cannot deny? Evidence that reveals the truth of where we really came from, why we are here and if we are alone in the Universe?

At the end of this episode they hammer away at science, at how it is broken, at how science resists their findings, and how science jumps to conclusions before all of the evidence is in. The drum gets beaten very, very hard here. And, this is just at a time when science denial is ascending.

In the episode, an AA host takes a Brazilian skull of some antiquity and has it CAT scanned and its DNA analyzed. The CAT scans show some items missing from what normal Homo sapiens skulls exhibit. The researcher states that they have never seen anything quite like it before. The DNA analysis only found mitochondrial DNA, so it could only assess the lineage of the female ancestor of the skull’s original owner, and found it to be like someone of Scottish ancestry.

So, these anomalous findings, all of which warrant further study, are used as a basis for their position that science jumps to conclusions and is resistant to their narratives and findings. And just where did these researches take place? At a London university research complex, about as mainstream as you can get!

And right after hearing that further research is warranted in the minds of the experts they consulted, and vigorously claiming that science jumps to conclusions too quickly (excluding their hypotheses, etc.), the host comes to the conclusion that the skull represents the results of an alien mating with a human female. WTF? How about a disease that no longer exists that results in deformations of bones in babies? How about a single mutation that chanced to survive for a generation or two? How about testing all of the other skulls in that collection to see if the results are consistent? Nope, we go straight to fucking aliens, literally!

The “resistance” they bemoan is called “skepticism.” Basically, extraordinary claims require extraordinary evidence and large qualities of it if you want to challenge established science. Yes, scientists often have problem changing their minds. Some scientists go to their graves clinging to ideas that have been discredited. Scientists are, after, people. But, science itself moves on. Look at how much Darwin’s theory of evolution was resisted by scientists. The theory of plate tectonics was mightily resisted. This is not a bug, it is a feature. Scientists, after all, have seen a great deal of evidence that fits into their current paradigms. They are going to have to see a great deal more to accept a new paradigm.

In the AA episode, the show points out any number of the limitations of carbon-14 dating of objects. These limitations are corroborated by mainstream academics, to whom they are well-known. (I am sure they were a surprise to a the AA producers.) But the show is just casting shade. One of the key limitations on carbon-14 dating is if a sample has been exposed to an enriched source of carbon-14, it will appear younger than it really is in that test. Some examples were provided that had dating results that showed the samples were from the future! (the concentration of carbon-14 was higher than baseline, not lower as would be expected.) Scientists look at this kind of anomalous result and assume that there is something wrong with the test and they repeat the test. Getting the same result, they assume the test is not working in this case. Reasons for the extra carbon-14 can be anything from contact with a meteor, exposure of the sample to volcanism, or an intense radiation sources, such as an atom bomb. Of course, the show goes off on the atom bomb diversion like a starving dog spotting a sausage.

In chemistry we had a set of “Standard Methods” for measuring quantities of chemicals in various substances (carbon in steel, strontium-90 in milk, residual lye in soap, etc.). At the end of each and every procedure was a section that listed know interferences with the test, not only acknowledging that there were things that could throw the test results off, but also that these were just the ones that were known and unknown interferences may also be involved because they are yet to be discovered. Every … single … damned … test had known limitations. This is something that scientists are quite comfortable with, including the need to get independent results from other tests to corroborate one’s findings.

Scientists are aware of the limitations of single tests, so they perform multiple tests. They are leery of the results of a single kind of test, so they look for evidence that is of an entirely different kind to corroborate findings.  Archaeologists and anthropologists use radiochemical dating procedures, and written records, and pottery patterns, and analysis of food wastes, and pollen identifications, and, and, … all trying to get a consistent picture of “when” and “what.”

Scientists are skeptical of their own findings (and especially of those who are their competitors). Scientists are also leery of jumping to conclusions. Even the producers of Ancient Aliens are. They have a formula for asking the leading questions that punctuate the episodes: they use the word “could” as in “could it not be the case that …” and then they always answer “ancient alien theorists say yes.” What they are asking is always “is such a thing possible.” They never ask is it probable.

Scientists are never certain, but this AA script kept hammering away with the phrase that “scientists crave certainty,” which is a strange way of saying scientists are skeptical of things they cannot support. Anyone who craves certainty is going to be miserable if they choose science as a career. All scientific finds are provisional. All “conclusions” may later be proven to be false, which is why all scientific conclusions are tentative. Nothing, absolutely nothing, is absolutely certain in science. Only in religion can you find absolute certainty … well, and in Ancient Aliens scripts.

I think they have turned the corner and are doing real damage to the public as they ramp up their anti-mainstream science rhetoric.

Marco Rubio and Creationists Can Relax

Sen. Marco Rubio of Florida was recently caught in an interview by a question about the age of the Earth and instead of responding with the “a bit over 4 billion years” that there is a scientific consensus for, he mumbled something about there being a “theological debate.” Most people are describing this as an example of his pandering to a conservative base who believe the Earth is less than 10,000 years old.

If you ask any of those “young Earth” Creationists, so-named because they believe in the Biblical story of creation of the planet and, well, the Universe, why they think the Earth id just a few thousand years old, they say it is a matter of their Christian faith.

Since the Christian faith is based solely on their Bible, I decided to check and, in fact, nowhere in the Bible does it say how old the Earth is. Some people, a little more in the thrall of the Creationists, can quote Bishop Usser’s estimate that the Earth was created in 4004 BC, specifically on the nightfall preceding 23 October 4004 BC, which means I and the planet share a birthday. It is curious that the worthy stated such a time, “nightfall” because “nightfall” is a condition that sweeps around the Earth once every 24 hours, so it occurs at different times in different places, but I digress.

The esteemed Bishop used certain assumptions about how long people lived and counted the generations which, with a little math, resulted in his estimate. But what most don’t know is that a great many other people did the same thing and came up with similar estimates of Earth’s birth date from roughly 3600 BC to 7000 BC. A few more modern folk, embarrassed about the difference between those dates and the date that geophysicists have come up with, namely ca. 4,300,000,000 BC have managed to stretch the birth date as far back as 20,000 BC.

Apparently, the people who believe the Bible and believe these “estimates,” also apparently believe the interpretations of people who lived hundreds of years ago and who had no knowledge of modern science. This is hard to believe especially for Evangelicals as they insist that they need no intermediaries to interpret the Bible. Some go so far to say that people who claim such positions are automatically deceivers.

For the rest of believers, there must be some doubt about the methods of people who take the same information and come up with “calculations” whose results differ by huge amounts. If the data is divinely inspired, should not the results come out the same for everyone? The fact that they do not indicates that the results of those calculations are merely the dreams of pointy-headed intellectuals.

So, if you base your faith on what the Bible actual says, you can rest easy. There is no dispute between the Bible and reality. And Marco Rubio can put away his dancing shoes.
