Revised 18 November 2014.
One of the most tiresome discussions that a scientific skeptic has when debunking and refuting pseudoscience or junk science (slightly different variations of the same theme) is what constitutes real evidence. You’d think that would be easy, “scientific evidence” should be the gold standard, but really, there is a range of evidence from garbage to convincing. So this is my guide to amateur (and if I do a good job, professional) scientific evidence. This is a major update of my original article on this topic, with less emphasis on Wikipedia, and more detail about scientific authority and hierarchy of evidence.
In today’s world of instant news, with memes and 140 character analyses flying across social media pretending to present knowledge in a manner that makes it appear authoritative. Even detailed, 2000 word articles that I write are often considered to be too long, and people only read the title or the concluding paragraph. This happens all the time in the amateur science circles specifically. For example, many people only read the abstract and, even there, only the conclusion of the abstract for scientific articles.
THE most popular article I ever wrote on this blog was one that thoroughly refuted a crazy meme that bananas kill cancer (which is an update of the original banana article). Hysterically, it was based on a complete misunderstanding of a study by “Japanese scientists” (the lead author was, in fact, an American, but whenever you see something that tries to claim authority by using unnamed, but smart sounding, scientists, be wary). Moreover, the conclusion made by the meme-author was based on ignorance about why a growth factor called “tumor necrosis factor” (TNF) that doesn’t do what it sounds like it does, about how a banana would never produce TNF, about how TNF would be broken down in the digestive system, about how it couldn’t be transported from the digestive system to the blood, and about how if you could eat enough bananas, if they did contain TNF, to have a biological effect, it would have to be more bananas than you could possibly eat, and the TNF effects would make you really sick. The banana meme did not have one single accurate assumption. None.
But still, it’s a popular belief. Just go to Facebook, and you’ll find someone promoting it. Like all anti-science memes, it’s a zombie, it reanimates from the dead and spreads its pseudoscience every few months, and I get thousands of hits from people trying to confirm the meme. Well, that’s actually good. I did the hard work of digging into the article and trying to figure out if this whole TNF thing was real.
Whenever I read statements from the anti-evolution/creationist crowd, I often wonder if they’re satisfied with their intellect and knowledge. Their level of denialism is so high that they cannot even get basic science right. In Vasko Kohlmayer’s Washington Times article, Is Richard Dawkins an ape?, decides to deny most basic biological knowledge just to make some point that humans are somehow “better” than an ape, and use it to “disprove” evolution. Kohlmayer’s logic, if you can call it that, is so fallacious, I’m not sure which fallacy would fit. Maybe I’ll just use them all.
Before we start, you should know a little bit about The Washington Times. It was founded by the Unification Church (better known as Moonies, from their namesake, Sun Myung Moon) as a competitor to the Washington Post, a rather progressive newspaper in Washington, DC. The Post had written some negative articles about Moonies back in the late 70’s, while it was the only newspaper in the US Capital. The Washington Times has a very conservative editorial bias, based upon anti-communism and “Judeo-Christian values.” Of course, the paper is generally a mouthpiece for the conservative movement in the US, with its preference for climate change and evolution denialism.

I know I shouldn’t use the conspiracy theory fallacy when talking about the pseudoscience-pushing science deniers, who are the bread and butter of topics for skeptics. But, when I keep observing the same ridiculous and insanely illogical arguments used in the same manner by all of the deniers, I begin to wonder if they don’t get together annually at the International Society of Pseudoscience meeting, usually held in Sedona, Arizona, ground zero of woo. They obviously share their stories, because we hear the same regurgitated stories in different contexts.
The antivaccinationists, creationists, anthropogenic global warming deniers, and whomever else pretends to use science to actually deny science frequently focus on a trope that “science makes mistakes.” And then they produce a list of historical events that “prove” that science is wrong. Of course, this indicates more of a misunderstanding of what is science and the history of science than it is a condemnation of science. But your typical science denier is probably not going to let facts get in the way of maintaining faith in their beliefs. So let’s deconstruct and discredit these “science makes mistakes” tropes.
By the way, in my story, I admit that “science makes mistakes,” so read on.

Neil deGrasse Tyson, probably the most popular astrophysicist, if not scientist, of this generation, replaced Carl Sagan as the spokesman of all things science for the country. While not ignoring Bill Nye‘s impact on making science education fun and approachable (and who took classes from Carl Sagan at Cornell University), Sagan literally passed the baton of being the country’s science teacher to Tyson.
For those of us on the left side of the political spectrum, Tyson is like the hero of the pro-science crowd. This past spring, Tyson hosted a program, Cosmos: A Spacetime Odyssey, which described and supported some of the great science ideas of our time–evolution, age of the universe, human caused climate change, and other major scientific principles. Ironically, the show was broadcast in the USA on the Fox TV network, whose news division can be charitably described as ultraconservative. Right wing Christian fundamentalist groups, one of the main key demographic groups who watch Fox News, loathed Cosmos for trumpeting scientific knowledge over religious interpretations in just about every one of the the 13 episodes.
Of course, for every reason that Fox News hated Cosmos (even though it was a huge ratings success for Fox, and has garnered a significant number of TV awards and nominations), those of us on the pro-science side loved it. Now, I’m a rarity in the science community in that I did not enjoy the show (the animations offended me on so many levels, but apparently kids loved it), I did watch every episode and would have to rank the episodes on evolution and global warming as some of the best science TV I’d ever seen–despite the lame graphics.

I’ve written over 640 articles over the past 2 ½ years, 3-4 a week. It’s fun, mostly. About 360 of those articles are on vaccines, vaccination, and you know, those who don’t like vaccines.
When I started, I wanted to write about all kinds of topics that always rub us skeptics the wrong way: creationism, global warming denialism, UFO’s, the Loch Ness Monster, Sasquatch, the Loch Ness Monster having an affair with Sasquatch, everything but the kitchen sink causing or curing cancer (seriously, it’s that bad with cancer), and, near the bottom of the list, vaccines. Why at the bottom of the list? I naively believed that vaccines were a settled question. You know, vaccinate or really horrible diseases will return. I guess I was wrong.
This is just a “sense of the readers” poll. So choose wisely. I might go in that direction.
As I have said many times, I’m a scientific skeptic. That is, I don’t just reject ideas simply to reject them, I actually reject or accept ideas based on the quality and quantity of evidence. I don’t pretend to know much about the Big Bang, but I know when it happened and what happened, but I leave it to experts to hash out the details. No one person can be an authority on every field of science, no matter how many initials follow their name. I’ve already mentioned how hard it is to become an expert in a scientific discipline.
If you read this blog regularly, you’d think I’m completely interested in vaccines, with a little bit here and there on GMO’s, evolution, and climate change. But my own personal interests in biology are, in no particular order, is evolution of man (about which I’ve written some), endocrinology (about which I’ve written nothing), and extinction events (about which I’ve written little here). I have co-authored a couple of articles on Wikipedia on extinction events, have read dozens of books on the major extinction events, and have attended many scientific conferences on mass extinction. I may not have an official degree in extinction geology and biology, but I have spent several thousand hours doing real research in the area.
But I’m pretty certain that the audience for this blog will find my discussion about extinction events to be a bit dull. However, I’m hoping that there is a cautionary tale about science that can be applied to some general rules I have about science.
A couple of years ago, I started editing an article on Wikipedia about the Younger Dryas impact hypothesis. Without going into too many details, it was a hypothesis (named after an Alpine flower) that some sort of comet or asteroid impact struck the ice sheet covering North America, about 13,000 years ago, which lead to the death of the megafauna (mammoths, sabertooth cats, and whatever else lived in North America). It is hypothesized that the impact actually caused a temporary reversal of the retreat of the glaciers towards the end of the glacial maximum.
I actually came across ran the article when I was reviewing some information I had read about climate change from the last glacial maximum (you know, when glaciers covered much of North America). I wanted to know if a bolide impact (meteor or comet) could caused a massive change in North America.

Scientific denialism (also known as pseudoskepticism) is the culture of denying an established scientific theory, law or fact despite overwhelming evidence, and usually for motives of convenience. Sometimes those motives are to create political gain for their supporters.
Two of the most annoying denier viewpoints are the darlings of the right wing: evolution denialism and global warming denialism. The former is more commonly known as creationism and is mostly an American phenomenon, though it is known in other countries. In the USA, creationism is a fundamental part of the Republican Party strategy across the country. The latter is sometimes mistakenly called global warming skepticism, because “skeptic” was stolen by the pseudoskeptics, but plainly is a right-wing belief across the world, often intersecting closely with the evolution deniers. In fact, much of the anti-evolution legislation pushed by Republican legislatures in the United States has an anti-global warming component.
Global warming and evolution is supported by a massive mountain of scientific evidence, and has been established by a definitive scientific consensus. Both are theories that are “well-substantiated explanations of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.” As I have stated before, rhetoric and debate are not going to refute these theories. We demand scientific data, produced in world class laboratories that have been published in top tier, high quality, high impact factor journals, and that has been subjected to tough analysis and criticism from peers.
Both global warming and evolution are well-substantiated explanations of the natural world. There is no debate, unless someone has a political or socio-economic bias.

A few days ago, a fellow pro-science person was concerned about a tweet she received. Her antagonist was claiming that if my friend had all that time to tweet, then she obviously wasn’t working in academics as she claimed.
I have a Twitter feed that flies across the top right corner of my screen. I have over 1200 followers, and I follow the tweets well over that number. I have varied interests, but to be honest, there are too many tweets. I only respond or retweet things I happen to see when I look up to that upper right corner of my computer’s screen. I know I miss some good stuff. But I think I find a few dozen every day that lead me to read news articles or peer-reviewed journals. Occasionally, I run across a Tweet that makes me laugh or think.
Yes it takes time, but from the moment I wake up until I go to bed, I’m reading, writing, texting/messaging other scientists for ideas. We discuss books we’ve read. All of us in science writing work very hard to get where we are, which cause an epiphany bout the science deniers. I have a theory about their behavior and dismissal of science. I cannot be sure it applies to everyone; for example, there are some seriously deranged people who blame everything in science on Reptilians, Illuminati, Jews, and the US Government (run by Jews I suppose). There’s no logic with those types.

Ah, South Carolina. The Palmetto State. A lovely state, with beautiful beaches and forests.
But also known as the Whoopee Cushion of the Nation. And they’ve blown up the cushion again, and the rest of the country is snickering.
Through the persistence of an eight-year old third grade student, Olivia McConnell, the South Carolina House voted 94-3 on HB 4482 in February to specify that the Columbian mammoth (Mammuthus columbi) as the official state fossil. Olivia wanted the mammoth as the state fossil because its teeth were one of the first vertebrate fossils found in North America, dug up by slaves on a South Carolina plantation in 1725.
The bill was sent to the South Carolina Senate, where it got quick treatment from the Senate Judiciary committee, and sent to the full Senate for a vote in late March.
So far, this is a great story. Young child, interested in fossils and history, trying to honor the fossil for her state. The bill to make this happens sails through the state House, and quickly moves through initial review in the Senate.
But this is South Carolina, and here comes that whoopee cushion.
On 25 March 2014, while HB 4482 was under discussion in the Senate, Kevin L. Bryant (R-District 3) sought to amend the bill to acknowledge Genesis 1:24-25, which describes the sixth day of creation, to recognize that some “god” was responsible for creating the Animal Kingdom. It was reported that Bryant explained on his website, “I attempted to recognize the creator.” Bryant’s amendment was ruled out of order based on parliamentary rules.
So did Bryant give up? Not when you have a whoopee cushion to make a great sound. So he doubled-down on his effort, and he sought to amend the bill to add “as created on the Sixth Day with the other beasts of the field” after each instance of “mammoth.” This amended bill passed the South Carolina Senate by a vote of 35-0 (so that means progressive Democrats voted for it), and was sent back to the Senate, where they could change the Senate wording.
There you go. The South Carolina whoopee cushion just let out the best flatulence sound ever.
Note. for those of you who actually accept science as the most accurate description of the age of the planet and evolution of organisms. The earth is 4.5 billion years old, and we have no evidence that it was created by anything other than the accretion of material from the early Solar System. Life on Earth arose 3.7 billion years and is described by the theory of abiogenesis, that is that life arose from organic compounds. The Columbian mammoth appears to evolved in North America around 126,000 years ago, dying out at the end of the last ice age, around 10,000 years ago. There are some unreliable information about Columbian mammoth remains dating to around 7600 years ago. In other words, the mammoth died out before it was even created in Christian religious myths.
A second note. See, no vaccines. Or Chili’s. But if Chili’s is making chili with vaccinated mammoth meat, I will certainly discuss it here. It would be an awesome story.
A third note. Because I was spending so much time on vaccines and Chili’s, I didn’t get to this article earlier. I’m like a week late, and on the internet that’s like 5 years late.
I’ve been told that I need to quit relying on the peer-reviewed journals for my scientific knowledge, because they are paid for by Big Government, Big Pharma, Big Agra, Big Hebrew and Big Whatever. They’re all just big with every single person involved dedicated to providing information to fool the people of earth.
Apparently, the only acceptable type of research is doing it yourself using Google. Or in a pinch, Bing.
Because I wanted to be more open-minded and to learn the Truth™ about everything. And here’s what I found.
