Scientific facts vs personal opinion about vaccines, evolution, climate change

scientific facts

When I write, I usually stick to scientific facts that are supported by evidence published in peer-reviewed biomedical journals. Because I can be rather blunt about a scientific topic, for example, stating that evolution is a fact, it may sound like I’m saying “my opinion is that evolution is a fact.” No, it’s a scientific fact, not a personal opinion.

When it comes to opinions vs scientific facts, there is a difference, a huge difference. An opinion is a preference for or judgment of something, generally supported by weak evidence. Or sometimes no evidence. A scientific fact only exists because there is a vast amount of supporting evidence.

My favorite color is blue or green, depends on the day. I think that mint and mushrooms taste horrible, and I can’t imagine what they’d taste like together. Doctor Who is boring. Soccer is even more boring to the point of inducing depression. These are all my opinions, meaning that evidence, especially the scientific kind, probably could not be found to support any of them (see Note 1).

Opinions may be unique to me alone or massively shared across the general populations but they all have one thing in common – they cannot be verified by evidence, except that I believe them.

As Jef Rouner wrote in the Houston Press,

There’s nothing wrong with an opinion on those things. The problem comes from people whose opinions are actually misconceptions. If you think vaccines cause autism you are expressing something factually wrong, not an opinion. The fact that you may still believe that vaccines cause autism does not move your misconception into the realm of valid opinion. Nor does the fact that many others share this opinion give it any more validity.

On the other side are scientific facts, which only exist because of evidence – unbiased evidence, along with well-designed experiments that give us that evidence. Let’s take a look at opinions vs scientific facts, just in case you think they are equivalent.

What is the scientific consensus, and what it means for evolution, climate change, and vaccines?

scientific consensus

In the hierarchy of scientific principles, the scientific consensus – that is, the collective opinion and judgment of scientific experts in a particular field – is an important method to separate real scientific ideas and conclusions from pseudoscience, cargo cult science, and other beliefs.

I often discuss scientific theories which “are large bodies of work that are a culmination of a composite of the products of many contributors over time and are substantiated by vast bodies of converging evidence. They unify and synchronize the scientific community’s view and approach to a particular scientific field.”

A scientific theory is not a wild and arbitrary guess, but it is built upon a foundation of scientific knowledge that itself is based on evidence accumulated from data that resulted from scientific experimentation. A scientific theory is considered to be the highest scientific principle, something that is missed by many science deniers. In addition, a scientific consensus is formed by a similar method – the accumulation of evidence.

I have written frequently about the scientific consensus because it is one of the most powerful pieces of evidence in a discussion about critical scientific issues of our day – evolution, climate change, vaccines, GMOs, and many other areas of science.

This tome has one goal – to clarify our understanding of the scientific consensus, and how we arrive at it. Through this information, maybe we all can see the power of it in determining what is real science and what are policy and cultural debates.

But the most important thing is that the scientific consensus (and theories, for that matter) are not opinions. They aren’t random thoughts pulled out of the ether. Scientific consensus is based on overwhelming scientific evidence published in respected journals.

Project Steve – the petition about science that actually supports science

Project Steve

Some of you know about Project Steve. Most probably don’t. So what is Project Steve?

Well, it is a tongue-in-cheek, sarcastic, humorous parody of the various declarations, petitions, and proclamations that science deniers use to “prove” there is a controversy about science, usually climate change, HIV/AIDS, evolution, and most recently, COVID-19.

One of the most famous is the Scientific Dissent from Darwinism (SDD), set up by the Seattle based, intelligent design think-tank (yes, you probably see all the irony). One more thing – Darwinism is one of those creationist code words that doesn’t mean what they think it means.

Although Charles Darwin was one of the first scientists to recognize evolution and natural selection, that was over 150 years ago. We know so much more about evolution today including the existence of DNA, genes, mutations, and so much more. Modern evolutionary biology has its roots in Darwin, but it has “evolved” far beyond what Darwin understood.

The great vaccine debate – only exists in the brains of anti-vaxxers

Lately, I’ve seen ludicrous articles from the anti-vaccine religion demanding a vaccine debate between the well-known pseudoscience liars, like Robert F Kennedy, Jr and Del Bigtree, and legitimate vaccine scientists and experts. I always laugh, and then I always recommend not participating.

The problem is that if you pay attention to any scientific topic, like climate change, evolution, and, yes, vaccines, you’d think that some scientific principles were actually being debated by scientists. The unfiltered information about important scientific subjects allows the science deniers to use a false equivalency to make it appear that the minority and scientifically unsupported point of view is equivalent to the scientific consensus which is always based on huge amounts of published evidence.

From listening to the screaming and yelling, you would think that there is a great vaccine debate. Or an evolution debate. Or a climate change debate. 

There aren’t any debates in any of those (and hundreds of other) scientific topics. Just because someone, like RFK Jr or Bigtree, thinks that there is some “debate,” it doesn’t mean there actually is one. All that happens is one side, almost always the science deniers, use misinformation, lies, anecdotes, and pseudoscience while attempting to scream and yell as loud as possible, then claim they’ve won.

Science can’t be debated. And there is no vaccine debate. Continue reading “The great vaccine debate – only exists in the brains of anti-vaxxers”

George Clooney PSA for good science including vaccines

George Clooney vaccines

George Clooney goes after all kinds of science deniers, including the anti-vaccine religion. Of course, Clooney may know more about vaccines when he played pediatrician Dr. Doug Ross on ER than most anti-vaxxers and their lame Google University degree

As a bonus, George Clooney goes after evolution deniers too. 

 

Yeah, I know, this is just clickbait to have George Clooney in the headline. Well, if that gets someone to check out some snark about the anti-vaxxers, I’ll accept that!

Vaccine research – it doesn’t mean what the anti-vaxxers think it means

vaccine research

How many times have you read a comment from an anti-vaccine zealot along the lines of “do your research, vaccines are bad.” That comment seems to imply two things – that the anti-vaxxer believes they have done real vaccine research, and those on the science/medicine side have not done real vaccine research.

Typical of nearly every claim made by the anti-vaccine religion, this is another one where they understate how hard vaccine research really is while overstating their actual skills and experience in comprehending real scientific research. I suppose this is a perfect example of the Dunning-Kruger effect – a cognitive bias wherein people without a strong scientific background fail to recognize their actual ineptitude in the field and mistakenly overrate their knowledge and abilities as greater than it is.

On the other hand, I’ve done real scientific research and worked hard at it. Time to explain. Continue reading “Vaccine research – it doesn’t mean what the anti-vaxxers think it means”

Science denialism politics – vaccines, GMOs, evolution, climate change

science denialism politics

On an episode of his HBO political talk show, Real Time with Bill Maher, Maher repeated his contention that the Republican Party, more generally the right wing of the American political spectrum, is the party of science denialism politics.

I am no fan of Bill Maher, because, in fact, he himself is is a science denier. Maher hits some of the top 10 list of science denialism: he’s an anti-vaccine crackpot, he’s pro-alternative medicine, he’s on the verge of AIDS denialism, and, to top it off, he hates GMO foods.

In other words, Maher, a leftist by any stretch of the meaning, embraces science denialism politics in a way that would probably inspire your local climate change or evolution denier on the right.

HBO’s other political news-ish program, Last Week Tonight with John Oliver, features British comedian Oliver, who is pro-science on every issue I’ve heard, including scientific research and vaccines.

Neil deGrasse Tyson was a guest on Maher’s episode, and contradicted him regarding the claim that Republicans hold the monopoly on junk science:

Don’t be too high and mighty there, because there are certain aspects of science denials that are squarely in the liberal left.

I like to generalize about the politics of science denialism politics – I and many others have claimed that the anti-GMO crowd is nothing more than the left’s version of climate change deniers. But some people have taken umbrage with Tyson’s comments, and believe that science denialism cannot be correlated with political beliefs.

One caveat about this article – it is primarily focused on American politics. In many countries, both the left and right accept the consensus on scientific principles like evolution and vaccines. Only in America is science denialism the default position, crossing party boundaries.

Let’s take a look at left vs. right ideas about science, and how each embrace science denialism and pseudoscience. It’s quite a bit more complicated than you can imagine.

GMO vs non-GMO foods – genetic modification techniques

GMO vs non-GMO foods

There are so many myths and tropes about genetically modified (GMO) foods, much like the vaccine world, it’s sometimes difficult to find out what is based in science, and what is not. Thus, I thought it would be the time to examine the crop modification techniques for GMO vs non-GMO foods.

Not to give away the conclusions early on, but all crops that end up being our food sources are genetically engineered. And have been for 10,000 years, since the dawn of human agriculture. If we hadn’t been genetically engineering our foods from day 1, we’d be eating corn that provided little nutritional value.

 

GMO vs non-GMO foods

Take a look at the evolution of corn from the wild ancestor, teosinte, to the delicious cobs of corn we eat during a summer BBQ – it’s closely tied to human advances in genetic engineering of food crops over the past 10,000 years. Teosinte is barely edible, and the amount of nutrition per plant pales compared to modern corn.

If you want corn that’s never been genetic engineered, then you’ll have to travel through some wild fields in Mexico to find yourself some teosinte. Then harvest a small warehouse of it to feed yourself for a couple of days. But 10,000 years of genetic modification, using a variety of techniques, gave us modern corn.

I know what you’re going to say. No, ancient farmers did not practice genetic modification. They didn’t stick a gene from a walrus into the corn plant – but then again modern genetic modification doesn’t do that either. Time to take a look at various genetic modification techniques used since the dawn of agriculture – let’s see what is the difference between GMO vs non-GMO foods.
