Juice Detoxes and Axioms 00:09:23
Today on Skeptoid, we've got another listener feedback episode, where I answer some emails sent in by people with more information about some past episodes.
This time, we're going to talk about crop circles, about the fact that humans and Neanderthals interbred, which we know because of genetic evidence, about juice detoxes, and about exactly what an axiom is, and more.
That's all coming up right now on Skeptoid.
Hi, I'm Alex Goldman.
You may know me as the host of Reply All, but I'm done with that.
I'm doing something else now.
I've started a new podcast called Hyperfixed.
On every episode of Hyperfixed, listeners write in with their problems and I try to solve them.
Some massive and life-altering, and some so minuscule it'll boggle your mind.
No matter the problem, no matter the size, I'm here for you.
That's HyperFixed, the new podcast from Radiotopia.
Find it wherever you listen to podcasts or at hyperfixedpod.com.
You're listening to Skeptoid.
I'm Brian Dunning from Skeptoid.com.
Listener feedback, Electric Boogaloo.
Once again, we open the mailbag to hear what Skeptoid listeners have to say.
In these shows, I don't include error correction as those go into their own dedicated shows.
Rather, I focus on listeners who can offer additional information or clarification on past shows or who have feedback or questions that are relevant to the conclusions.
Wherever appropriate, I try to always update the online transcripts with this information.
So let's see what the current batch of feedback looks like this month.
We'll get started with Vinny, who wrote in about our old episode on crop circles.
Hello, I have read your article about the crop circle jerks, and I enjoyed it.
However, it does not cover the complete subject.
There are still bits of pro-circle evidence that I have not had much luck with debunking.
The size of some circles compared with how long it would take people to make it in one night, the stems of the crushed plants being popped from the inside as from heat expansion or something, and the plants themselves becoming healthier.
There could be more that I have not heard.
You're doing a great service with your podcasts and articles when so many people in the world ignore the value of truth.
Cheers, Vinny.
Vinny, I would encourage you to recall two of our favorite mantras here at Skeptoid.
Hitchens' razor, what can be asserted without evidence can be dismissed without evidence, and Hyman's categorical imperative, do not try to explain something until you are sure there is something to be explained.
What you're describing as pro-circle evidence is more accurately described as very poorly evidenced claims made by true believers who are passionately dedicated to their belief that art in crop fields has a paranormal explanation.
Before you spend any effort on these claims, you should first take some steps to verify that these are indeed consistently reproducible observations.
A great place to start with this is asking the growers themselves.
Go to your local wheat growers association or corn growers association and do as I do all the time when I'm researching a subject.
Ask to be put directly in touch with someone who has been affected by this.
More than likely, you'll find the association happy to help and you'll start getting emails from farmers who have been through this.
I almost always find that people are delighted to talk about their expertise.
Too often, people researching Fortean phenomena limit their research to stuff on the internet written by either died-in-the-wool skeptics or impassioned true believers.
It seems many people have forgotten how to pick up the phone and actually talk to a real person in the real world.
I think you'll find the more far-fetched claims, like those you cite, are unknown outside the true believer community.
For this next one, I'm not going to read any one specific email because I got about a thousand of them, each giving some variation on the same theme.
In my episode called, No, You Shouldn't Question Everything, I gave concepts that are axiomatic as one type of thing that is usually not worth your time to question.
For instance, gravity is real, the laws of thermodynamics, 2 plus 2 equals 4.
I used the word axiom to refer to a concept that's so firmly proven that there's no practical point in re-examining it, generally the way the word is used in ordinary language.
Predictably, experts from every academic discipline wrote in claiming I'd misused the word, which it turns out has different formal definitions in different disciplines.
To some, an axiom is a theorem.
To others, an axiom is a postulate.
To still others, it's a proof.
I heard from everyone from mathematicians to philosophers.
In fact, each of you who thinks your specific definition is the only correct and universally accepted one is wrong.
There is no way I could have phrased what I said and pleased everyone who insists on a discipline-specific definition of axiom.
I say to everyone, relax.
You know what I meant.
It's my show and I reserve the right to speak colloquially.
Listener Jason wrote in with a report of some field research.
There are many chains of juice stores in the world that make implausible health claims, but Jason went to one in Los Angeles.
Their website makes a number of claims that drinking juice, quote, detoxifies the body.
They make assertions like, everyday life contributes to the congestion and buildup of harmful toxins in the body from processed foods, and sweating helps to release toxins.
Jason emailed them, asking them to specify exactly what toxins I'd be flushing from my system.
Their response pretty much sums up the cold-pressed juice craze.
And he got a reply.
Hey, Jason, unfortunately, due to regulations by the FDA, we are unable to specify exact health claims for our products.
We would recommend you consult with your physician if you have questions on the personal health benefits of juicing.
All the best, Ben.
They are, however, more than happy to specify vague and misleading health claims for their products.
Folks, juice do not, quote, remove toxins, which is exactly the reason these companies do not specify what toxins or by what mechanism.
Cleansing products do not do anything except provide a high-sugar liquid diet for a few days.
The only thing they cleanse is your wallet.
You have kidneys and a liver, which provide all the all-natural detoxification your body will ever need.
In a world that can feel overwhelming, spreading thoughtful, evidence-based content is one of the best ways to make a positive impact.
Ask your local public radio station to air the Skeptoid Files, a 30-minute radio-friendly version of Skeptoid that pairs two related episodes promoting real science, true history, and critical thinking.
And in these challenging times for public media, we're offering these broadcasts for free to radio stations, available on the PRX Exchange or directly from Skeptoid Media.
It's an easy ask.
Just send a quick message to your station's programming director.
By helping to bring the skeptoid files to the airwaves, you'll help promote the essential skills we all need to tell fact from fiction.
Just go to your local station's website, find the programming director's email address, or just their general email address.
You can even use the telephone.
I know that might sound crazy.
It's an old legacy device that allows real-time voice communication.
I know that's weird, but hey, it's an option.
The world can feel chaotic, but you're not powerless.
When you promote critical thinking, you can help your community tell fact from fiction.
And that's how we shape a better future.
In uncertain times, spreading good ideas can make you feel helpful, not helpless.
Let's stand up for reason, truth, and understanding.
Together, get them to air the skeptoid files from Skeptoid Media, available on the PRX Exchange, and they'll know what that is.
Remember when the conspiracy theory du jour was that President Barack Obama was going to round up law-abiding citizens into FEMA prison camps as a prelude for orderly execution?
Part of this tapestry of complex mythology was that some 500,000 boxes called coffin liners were being stockpiled in Madison, Georgia in preparation for all the expected bodies to be buried.
Photographs were even produced online, and indeed there was a giant lot stacked with mind-boggling numbers of these black cases.
Neanderthal DNA in Asia 00:02:49
I did a student questions episode where I was asked about these, but at the time, I couldn't quite find the answer.
Listener Thomas from Germany had better Google Foo skills than I did, and he turned up a thorough debunk of the conspiracy claim on Mick West's site, Meta Bunk.
The photo did indeed show tens of thousands of these plastic containers in a field, but they had nothing to do with FEMA.
According to West, they are actually not coffins or caskets.
They are burial vaults, also known as graveliners, depending on how well they seal water out.
A burial vault is something that a coffin goes in and is not used for interring people by itself.
It's used in several states in the U.S. where ground subsidence is an issue in graveyards.
A local paper, the Morgan County Citizen, had reported on this in 2008 when calls started pouring into the vault's manufacturer, a company called Vantage Products Corporation.
Vantage produced the lease for the industrial property on which they stored their inventory of the standard air seal model in black.
They'd initially moved 70 to 80,000 of the vaults onto the property, but it was down to about 50,000 at the time.
The last of them appears to have been moved elsewhere as of 2010.
Conspiracy theory fizzled.
Science moves along, so it's not unexpected that when a show runs 10 years or more, some of its information gets superseded.
Way back in 2007, I did an episode on claims of relic Neanderthals living in Asia, supposedly as an explanation for the Yeti.
At the time, I said, The Max Planck Institute is actually in the process of assembling a Neanderthal genome from a fragment of femur found in Croatia in 1980.
Until the genome is complete, we won't know for certain whether it was possible for Homo sapiens and Homo Neanderthalensis to interbreed.
Most DNA testing so far indicates that if humans and Neanderthals ever did interbreed, it was not at a significant level.
Listener Todd wrote in, Hi, Brian.
I found your site and I'm enjoying reading the articles.
I just read the article on possible early hominids living in Asia, like the Yeti and Almos.
It said that there isn't any evidence of significant interbreeding with modern humans and Neanderthals.
You may want to update this page since recent evidence has shown that many humans do have a small but significant amount of Neanderthal DNA.
I see that the article was written 10 years ago before this discovery was made.
Thanks for running an inquisitive, articulate, and enjoyable series.
Followed quickly by Juanita.
Evidence for Interbreeding 00:03:05
Hi, Skeptoid.
This is my first visit to your website, and I have found it very interesting.
However, in your article on Neanderthals in present-day Asia, there is an update needed.
In fact, we do know that many people today have Neanderthal DNA.
For example, check out the National Geographic Genome Project.
Thanks for the Skeptoid website.
I'm a big fan of science and truth over woo.
And it's true, humans and Neanderthals did interbreed.
They did so after humans left Africa, probably in the Middle East.
It turns out that Neanderthal DNA is found in every ethnic group on the planet, except Africans.
Once the interbreeding took place, Homo sapiens spread out and took those genetic markers to every other corner of the globe, which is why we find Neanderthal DNA in humans living in places where Neanderthals never ventured, like China and Papua New Guinea.
So, listeners, please keep the feedback rolling in.
Every little bit improves the quality of Skeptoid as a resource for people searching the web.
And we all know what a minefield that can be.
I do the research and the writing and the recording and all that behind-the-scenes puttering about.
But you're the ones who suggest the topics, provide the feedback, and keep the show on the straight and narrow.
Skeptoid is your podcast.
You're the custodians.
You're the executive producers.
I just hope you don't fire me.
