Skeptical Raptor's Blog hunting pseudoscience in the internet jungle

How to evaluate the quality of scientific research

einstein-science-false-balanceOne 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.

Agricultural pesticides cause autism? Don’t hold your breath.

pregnant-fieldIf you’re a regular reader of this blog, you would think that I spend a lot of time discussing autism spectrum disorders (ASD). But the goals of this blog is weed out and debunk pseudoscientific beliefs, especially some of the more popular ones. Probably the most ridiculous had been the fraudulently invented and eventually thoroughly debunked link between vaccines and autism. That belief is completely dead, right? Well, not really. Irrational and, frankly cult-like, groups like Age of Autism refuse to give up. Of course, the Age of Autism is so deluded by their illogical and unscientific beliefs, they oppose funding for genetic research into autism.

Not everyone in the world of ASD has that fanatical hold onto the “vaccines cause autism” trope. Most real scientists accept that the likely cause of ASD is some combination of genetics and environment. But that hasn’t stopped people from claiming that everything, but the kitchen sink, causes ASD. About three years ago, Emily Willingham, Ph.D., whom I consider to be one of the leading ASD scientific experts on this planet, wrote a hysterical, but still appropriate, article about all the popular causes of ASD. Older mothers. Older fathers. Depressed mothers. Fingers. Facial features. Facial features?

Dr. Willingham wrote about around 50 different causes of ASD, including refrigerator mothers (but not kitchen sink mothers)–it has nothing to do with actual refrigerators. That article was very important to me, because it formed the basis of my skepticism about popular beliefs regarding correlation and causality. It’s not just ASD, but other areas, like cancer causes and cures, which seem to attract the everything-but-the-kitchen-sink science.

How science deniers use false equivalency to pretend there’s a debate

If you read a news article, Google a scientific topic, or watch TV, you’d think that some scientific principles were actually being debated by scientists. From listening to the screaming and yelling, you would think that scientists aren’t sure about evolution, vaccines, global warming, and the age of the earth (or even the age of the universe). There are even those who think there’s a debate that HIV doesn’t cause AIDS.

Science vs BS

Part of the problem is that some people think that science is unapproachable and too hard to comprehend. It isn’t. Now, that doesn’t mean it’s easy, because it shouldn’t be. Answering questions about the natural universe requires, demands that scientist approach it with the least amount of bias and the most amount of evidence. And sometimes it is complex and nuanced, but why do people give false balance to someone, without the expertise or education in the field, as if they know more about the issue than does the scientist.

To become a world class architect and to design a skyscraper isn’t easy, but we non-architects can observe what we see, and accept that the building isn’t going to topple over in a hurricane. Do we presume to know how the foundation has to be built to support the building? Or what materials are used to give flexibility in a wind, but strong enough to not collapse? Mostly, we don’t, we trust that there isn’t a massive conspiracy to build unsafe skyscrapers because architects are being paid off by Big Concrete to use cheaper materials. We don’t question the architects’s motives or whether there are solid engineering principles, probably outside of most of our understanding, that were employed to make that skyscraper.

It’s the same with science. We can accept scientific principles without doing the research ourselves. But, and it’s a big but, if you want to dispute accepted science, then you have to bring science to the table not a false debate. Science isn’t hard, but it isn’t easy either. You cannot deny basic scientific facts without getting a solid education, opening a scientific laboratory staffed with world-class scientists, and then publishing peer-reviewed articles that can help move the prevailing scientific consensus. You cannot spend an hour or a day or even a week Googling a few websites and then loudly proclaim that the scientific consensus is wrong; no, you need to do the hard work. Until you do, those of us who are skeptics and scientists get to ignore you, and we get to continue with the current consensus.

The Irish Catholic children’s home scandal–it’s NOT about vaccines

children-at-st-marysThere’s an appalling story out of Ireland that has dominated the news for the past few days. Over a period of 35 years, St Mary’s Mother and Baby Home, a Catholic home for unwed mothers in County Galway (on the west coast of Ireland), apparently buried some children in a sewer system after dying in that home. You might have heard from some irresponsible journalists that over 800 children were buried in the septic tank, without questioning whether 800 bodies could actually be buried in the septic system, and without determining when the home was moved to a County sanitary sewer system, making it impossible to dump dead children in the septic tank. OK, that’s a small point.

According to the individual who actually uncovered this atrocity, Catherine Corless, an academic historian, she claims, through her research of birth records and other information, around 800 children died at this home over 36 years. The Irish Times reports, “between 1925, when the home opened, and 1937 the tank remained in use. During that period 204 children died at the home. Corless admits that it now seems impossible to her that more than 200 bodies could have been put in a working sewage tank.” OK, it’s sad and maddening that 22 children died every year at this home, even if infant mortality rates were substantially higher back then because of malnutrition and vaccine preventable diseases (like measles, mumps, polio, rotavirus and others) that would run rampant through closed quarters like that.

So the first myth we need to debunk is that there are 800 bodies buried in a septic tank–there aren’t. But, like I’ve said, that’s really just a minor point (setting aside the atrocity itself, which we’ll address later), because there are some other issues that have arisen with this story that also need to be discussed honestly.

Science can anger people even in the most obscure fields

 

younger-dryas-cometAs 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.

GMO opponents are the left’s version of global warming deniers

Zombies and GMO. Can't go wrong.

Zombies and GMO. Can’t go wrong.

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.

What does science say about GMO’s–they’re safe

scaremongering-WordleThe science deniers of the world, whether they deny evolution, global warming, vaccines, or GMO safety, spend their time inventing pseudoscience to support their beliefs and claims. As I wrote a few weeks ago, “Pseudoscience is easy. It doesn’t take work. It’s the lazy man’s (or woman’s) “science.” But it has no value, and because it lacks high quality evidence in support of it, it should be dismissed, and it should not be a part of the conversation.”

Alternatively, real science is really hard. And it takes time. And it’s based on high quality evidence. And it is repeated. And it is almost always published in high quality journals. As I’ve said a thousand times, real science takes hard work and is intellectually challenging. You just don’t wake up one day and say “I’m a scientist.” No, it requires college, graduate school, teaching, working in world class laboratories, publishing, defending your ideas to your peers, and one day, if you don’t stop, you will be an authority in your little field of science.

The anti-GMO crowd is mostly lazy. They have this luddite belief that all technology is bad, but have absolutely no evidence to support it. Sure, they pick out one or two poorly done articles and then shout for all the world to hear “GMO’s are dangerous to…bees, humans, babies, whales, trees” over and over and over again.  Yet what do the GMO refusers really bring to the table?

Correlation does not imply causation. Except when it does.

One of the central tenets of the pro-vaccine world is that correlation does not imply causation. We, the pro-science/pro-vaccine world, dismiss correlation, if it even can be shown, as indicative of any causal relationship. Conflating causation and correlation is somewhat different than the logical fallacy of post hoc ergo propter hoc, where one thinks one event follows the first event because of the existence of the first event. I’m sure all good luck charms and superstitions, like walking under a ladder, are related to the post hoc ergo propter hoc fallacy. So when I walk under a ladder, then trip on a black cat, then crash into a mirror, they were all related to walking under the ladder.

Correlation and causation are a very critical part of scientific research. Basically, correlation is the statistical relationship between two random sets of data. The closer the relationship, the higher the correlation. However, without further data, correlation may not imply causation, that the one set of data has some influence over the other.

The false ideology of science deniers–research is easy

tyson-science-trueA 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.

Trying to save lives with the Frankensquito

giant-mosquitoFour hundred years ago, the world was so afraid of Galileo’s scientific ideas that the Catholic Church put him under house arrest for the rest of his life. And he was just describing heliocentrism, the astronomical model where the earth revolves around the sun. Very important to our understanding of the universe, but it was not a life or death matter. You would assume that if a new scientific idea that would help people live longer and healthier, then there would be no fear. However, that assumption is disproven again and again with the antivaccine gang and the Big Pharma ad hominems that we hear frequently.

Over the past couple of years, I’ve written about an innovative an small UK based biotech firm, Oxitec, which has developed genetically modified male mosquitos, sometimes referred to as  Frankensquitos (at term I fully embrace as being both ironic and descriptive) that would mate with wild females. Those females would produce offspring that would not survive to adults, because they require an antibiotic, tetracycline, in their diet, something that isn’t usually available in the the wild. Over time, with multiple releases of males, the population of the Aedes aegypti mosquito, which is the vector for transmitting Dengue fever. would fall to such a level that transmission of the the disease would be significantly reduced, if not completely stopped.

Jenny McCarthy lies about vaccines. Surprise.

Jenny McCarthy is the erstwhile MTV drunk college dating game hostess, and current “journalist” on The View, an American daytime talk show on the ABC television network (owned by Disney). This transformation, of sorts, occurred despite widespread condemnation from scientists, journalists, and yours truly about her loud and annoying antivaccine rhetoric. Clearly, no one of any note supported her being hired on the View, except for websites like the Age of Pushing Nonsense To Harm Children.

This is old news. If you didn’t know, Jenny also has a newspaper column at the Chicago Sun-Times, where, I suppose, she can comment on anything she likes. I have never read it. Until I did. In her column of 12 April 2014, she wrote:

I am not “anti-vaccine.” This is not a change in my stance nor is it a new position that I have recently adopted. For years, I have repeatedly stated that I am, in fact, “pro-vaccine” and for years I have been wrongly branded as “anti-vaccine.”

Wait! What? She said she is not anti-vaccine?

Again. Again. And again. Thanks Bill Nye.

Again. Again. And again. Thanks Bill Nye.

Mammoth created on sixth day–according to South Carolina

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.

south-carolina-mammoth

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.

One hour of research on Google–obviously all science is wrong

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. 

Science is obviously wrong about everything. Including unicorns. Obviously wrong about unicorns.

Hey vaccine deniers–it’s just simple math

When dealing with those pushing pseudoscience, like the antivaccination cult, the most frustrating thing is that they tend to ignore and deny the most basic tenets of science. If denying the fact of gravity would further their goals of “proving” vaccines are neither effective nor safe, they would do so. For all I know, they have.

Sam Harris, who has a Ph.D. in neuroscience from UCLA (which is ironic), and is one of leading science philosophers of our generation, says this about those who cling to pseudoscience:

Water is two parts hydrogen and one part oxygen. What if someone says, “Well, that’s not how I choose to think about water.”? All we can do is appeal to scientific values. And if he doesn’t share those values, the conversation is over. If someone doesn’t value evidence, what evidence are you going to provide to prove they should value it? If someone doesn’t value logic, what logical argument could you provide to show the importance of logic?

If the antivaccination movement didn’t lead to epidemics of long-gone diseases, which can harm and kill children, the conversation would be over. I would just put the vaccine deniers in the same group as evolution deniers (creationists) or gravity deniers (there has to be some, somewhere). I would mock their pseudoscience, and move on. Of course, their denialism does lead to deaths of children, so we have to do what is right, and stop their lies, misinformation and ignorance in every forum we can.

We have to appeal to scientific values, and despite the fact that antivaccination pushers don’t share those values, we must continue to try. I have gotten enough emails and comments from people that they have started to vaccinate because of what I have written, so maybe some child’s life is better because all of us who support vaccines are heard.

Anti-GMO cult trumpets GMO genes transfer to wild rice–update

GMO_riceIt is well accepted observation that when the pseudoscience or anti-science crowd runs out of supporting evidence (usually when it’s thoroughly debunked by scientific skeptics), it has to rely upon the whole range of logical fallacies, which are errors in reasoning to support a position in an argument or debate. Because scientific skeptics (or if we’re talking about medicine, science based medicine) always demand high quality evidence to support their own claims, or alternatively demanding evidence from other making suspicious claims, the anti-science and pseudoscience pushing troupes frequently cherry pick “peer-reviewed” research to use as their “proof” for their claims. 

Cherry picking makes it appear that there a nothing but ripe beautiful cherries of evidence supporting your position. The problem is when you look at the whole basket of cherry’s you see all sorts quality. Same with peer-reviewed evidence. You may find one article that says “Point A is correct.” But what is the quality of that article? How does it fit with all the other articles that say “Point A is not only incorrect, but Conclusion B is the scientific consensus.” You can’t cherry pick one article, without understanding and analyzing the vast breadth of research in a field.

Moreover, because the pseudoscience promoters are resort to confirmation bias, always looking for evidence to support their beliefs rather than seeing what the evidence supports, they ignore the vast majority of evidence or tend to misinterpret the evidence. So, when you read some blog post or pseudo-news article about a published scientific article that says GMO’s are dangerous, you need to dig beyond the headlines, and head right to the scientific source to determine what is really being said. And this happened recently.

Vaccines increase rate of Type 1 diabetes–another myth refuted

Diabetes wordcloudIf you cruise around the internet, engaging with the antivaccination cultists, you will pick up on their standard tropes, lies, and other anti-science commentary. One that has always bothered me, not because that it was a lie, but because I had enough evidence floating in my brain that I was wondering if it were true–that vaccines might lead to Type 1 diabetes.

A lot of the vaccine deniers believe that vaccines cause a lot of everything, and the one that says vaccines cause Type 1 diabetes is one of their most popular. And probably the biggest promoter of this trope is Markus Heinze, an antivaccine author, whose daughter contracted Type 1 diabetes when she was young, and he blamed a vaccination as the cause.

In a long-winded rant, Heinze brings up the old ad hominem argument about not trusting research paid off by pharmaceutical companies, because they’re hiding all the evil about vaccines. That doctors are clueless, because Heinze’s 2 hours of Google research is more valuable. Oh and his 18 months studying psychology at a low level college in Kentucky somehow makes him an expert on anti-psychotics and depression medications. You know, because the four years of medical school, and another 8 years of post medical-school training to be a psychiatrist is irrelevant to him. Yes, he’s an arrogant man.

Cancer has become more prevalent in the USA–another myth debunked

cancer-foods-causeOne of the enduring zombified tropes of the junk science world is that the rate of cancer in people is higher today than it was in the past. Depending on the one screaming this myth, this rate of cancer increase is a result of A) vaccines, B) GMO crops, C) pasteurized milk, D) non-organic foods, or E) everything.

To be certain, there are a few things that do cause cancer, like smoking, asbestos, and obesity (and there are a lot of causes of obesity, it might be impossible to link the cause of obesity directly with cancer). Here and there, you might run across a study that mentions one thing or another may or may not increase or reduce the risk of cancer. But most of those studies are one-off primary research, usually using small groups, providing little clinical evidence that you may or may not be able to increase or decrease the risk of cancer. Wait until we can find these studies in large systematic reviews, before deciding that this or that may or may not increase or decrease the risk of cancer.

Australian vaccine denier group changes name–still a lie

 

 

Thanks to StopAVN.

Thanks to StopAVN.

About a year ago, Meryl Dorey, Australia’s infamous American-born vaccine denialist and anti-science promoter, and her Australian anti-Vaccine Network (AVN) was ordered to change its misleading name or be shut down. The New South Wales (an Australian state) Office of Fair Trading left an order at the home of AVN  president Meryl Dorey yesterday with a letter of action, “labeling the network’s name misleading and a detriment to the community.” Given Dorey’s, and by extension the AVN’s, well known antivaccination stance, this order wasn’t surprising.

Dorey and AVN attempted to fight the order through Australian courts, but lost. And was recently ordered to pay A$11,000 in court costs to cover the legal fees of Stop the Australian Vaccination Network campaigner Dan Buzzard after he appealed against an apprehended violence order she took out against him last year. She actually then went to AVN and begged for money to pay for it, since I guess she does not get the Big Pharma shill money. Amusingly, the group, formerly known as the Australian Vaccine Network, and their leader/mouthpiece, Meryl Dorey, kept prevaricating about changing the name. But finally the Australian government ordered her to change the name or there will be consequences. 

Finally, Meryl and gang renamed their group the Australian Vaccine-Skeptics Network (still abbreviated as AVN). Ironically, Meryl and AVN first tried to name the group the “Australian Vaccine Sceptics Network”, using the Australian English spelling of the word, but a real skeptic (or sceptic) already owned that name. In even more irony, Meryl called the real owners of the trade name, a “hate group.” No, she really said that given Meryl and her group are the definition of a hate group.

Poll: which scientific principle do you accept or reject

One of the things that drive pro-science types crazy (amongst a few hundred things, but still let me proceed) is when someone who seems to be rational about a scientific idea, then drop a bomb that they accept something so pseudoscientific, you have to wonder about everything else that person accepts.

I know people who argue vociferously for the fact of evolution, then claim that astrology predicts the future. Or someone who will accept everything in science, but claim that vaccines are dangerous. My personal favorite are those who proclaim widely that global warming deniers are crazy lunatics, then try to convince us that GMO crops are dangerous, using the same exact tactics and lack of science as the global warming deniers.

I began to wonder where my readers stood on the four major scientific consensuses (I assume that’s the plural of consensus, but it looks weird) that I discuss regularly here. They are:

  1. Evolution, which is supported by the overwhelming consensus of scientists throughout the world.
  2. Anthropogenic (human caused) global warming, which is supported by the overwhelming consensus of scientists throughout the world.
  3. Vaccinations (the safety and effectiveness of vaccines to prevent disease), which is supported by the overwhelming consensus of scientists throughout the world.
  4. The safety of GM (genetically modified) foods, which is supported by the overwhelming consensus of scientists throughout the world.

See what I did there?

In this week’s poll, a double version, first, just vote on how many of these four key scientific principles you accept. Then second, choose which ones you reject. Easy!

GMO foods transfer DNA to humans-another myth

franken-corn-DNAHere we go again. A pseudoscience pushing website (which occasionally tosses in stories about real science) is trumpeting a primary research study (published 6 months ago) that may, or may not, indicate that plant DNA may survive intact in the digestive tract and show up in the bloodstream. You just know what they’re going to say next.

This will now be all about genetically modified foods.
