From criminal cases to designer babies, DNA is reshaping humanity’s future. Michael Regilio unravels this double helix of discovery on Skeptical Sunday!
Welcome to Skeptical Sunday, a special edition of The Jordan Harbinger Show where Jordan and a guest break down a topic that you may have never thought about, open things up, and debunk common misconceptions. This time around, we’re joined by skeptic, comedian, and podcaster Michael Regilio!
On This Week’s Skeptical Sunday, We Discuss:
- DNA is simultaneously microscopic and massive in scale — while coiled up tightly in each cell’s nucleus, if you unraveled all the DNA in a single human body and laid it end-to-end, it would stretch to the sun not once, but 600 times! This mind-bending fact perfectly illustrates how we’re all walking around with an astronomical amount of genetic information packed into our cells.
- The ethical implications of DNA databases are more complex than a double helix — even if you never take a genetic test yourself, your relatives’ DNA decisions can expose your genetic information. It’s like playing genetic poker where someone else can accidentally show your hand. This raises serious concerns about privacy, insurance discrimination, and how genetic information could be weaponized by bad actors.
- CRISPR technology has opened Pandora’s genetic toolbox — while it offers incredible potential for treating diseases like sickle cell anemia, it also enables the possibility of “designer babies” and genetic enhancements that could create new forms of social inequality. We’re essentially writing code for humans now, but without a clear user manual for the consequences.
- DNA evidence has revolutionized criminal justice — but it took decades to establish proper standards and protocols. From its first use in catching Colin Pitchfork (whose villainous name seems almost too on-the-nose) to modern genetic genealogy solving cold cases, DNA has become the ultimate witness that never forgets and never lies.
- Understanding and working with DNA is becoming increasingly accessible and beneficial — from personalized medicine to ancestry exploration to crop improvements, we all have opportunities to engage with and benefit from DNA science. By staying informed about genetic advances while thoughtfully considering their implications, we can help shape a future where this powerful technology serves humanity’s best interests rather than our darker impulses.

1105: DNA | Skeptical Sunday
This transcript is yet untouched by human hands. Please proceed with caution as we sort through what the robots have given us. We appreciate your patience!
[00:00:00] Jordan Harbinger: Welcome to Skeptical Sunday. I'm your host, Jordan Harbinger. Today I am here with Skeptical Sunday co-host Michael Regilio on the Jordan Harbinger Show. We decode the stories, secrets, and skills of the world's most fascinating people and turn their wisdom into practical advice that you can use to impact your own life.
And those around you. Our mission is to help you become a better informed, more critical thinker. And during the week, we have long form conversations with a variety of amazing folks from spies to CEOs, athletes, authors, thinkers, and performers. On Sundays, though, we do Skeptical Sunday, where a rotating guest, co-host and I break down a topic you may have never thought about and debunk common misconceptions about that topic.
Topics such as fast fashion, weddings, the death industry, homeopathy, hypnosis, diet pills, and more. And if you're new to the show or you wanna tell your friends about the show, I suggest our episode starter packs. These are collections of our favorite episodes on persuasion, negotiation, disinformation psychology, cyber warfare, crime, and cults and more.
That'll help new listeners get a taste of everything we do here on the show, or almost everything. Just visit Jordan harbinger.com/start or search for us in your Spotify app to get started. Today, DNA and genes are everywhere, both figuratively and literally. Get your mind outta the gutter Folks. Not only are they the building blocks of every living thing, but they also hold the secrets to our ancestry, unlock the mysteries of unsolved crimes, and help doctors predict and treat potential health conditions even more.
Maury Povich famously used DNA to determine if somebody is or is not the father.
[00:01:29] Michael Regilio: You are not.
[00:01:34] Jordan Harbinger: But as technology advances, we're now capable of manipulating DNA, raising profound questions about what it means to be human. Are we on the brink of a beautiful new age or stepping into a dystopian sci-fi nightmare to help us navigate this microscopic landscape, skeptic, Michael Regilio is here to help us unravel the double helix of ethical dilemmas and excitement around DNA.
[00:01:55] Michael Regilio: Hey, Jordan, if I may a quick compliment on you. You seem quite healthy and smart. Thank you. I do what I can. Sure. It's important to stay fit and sharp, but the fact of the matter is you had little to do with being healthy and smart. In fact, you had no say in the matter at all. You were predetermined to be those things.
You just made the most of it. So you're talking about my genetic predisposition.
[00:02:18] Jordan Harbinger: right? Yep. It's in your genes and it's in your DNA. So I think we all have some sense of what our DNA and genes are, but why don't you break it down for us? I don't actually know the difference. I.
[00:02:29] Michael Regilio: Okay, sure. DNA or deoxyribonucleic acid is a molecule, and a molecule is a bunch of atoms stuck together.
This particular molecule, DNA, is coiled up in the nucleus of every cell in our body, and each coiled up strand of DNA is the complete blueprint to make,
[00:02:45] Jordan Harbinger: uh. You. Yes, I've seen Jurassic Park, but I'm still mind blown by El. This cells are really small and the idea that a cell can replicate itself is pretty wild, but the fact that each cell also holds the blueprint to make another entire me is just crazy.
I. Yeah,
[00:03:02] Michael Regilio: cells are really small. And to illustrate this, let me hit you with this fact. Every time you scratch your nose or rub your arm, dead skin cells fall off your body. Humans shed about 600,000
[00:03:13] Jordan Harbinger: skin cells per day. You'd think you'd notice if you lost 600,000 of pretty much anything. But no, I've never noticed this generally.
[00:03:21] Michael Regilio: So we're talking. Tiny here, and the DNA strand in each cell isn't just coiled up in the cell. It's actually coiled up in a much smaller part of the cell. The
[00:03:29] Jordan Harbinger: nucleus. Aha. Okay, so seventh grade science class coming in handy here. DNA is obviously extra tiny if it's all curled up in the nucleus of the cell.
Uh, actually only kind. Kind of sounds a little bit less scientific than we like to be on Skeptical Sunday, but I'm gonna roll with it. Okay. Look, if
[00:03:45] Michael Regilio: Uncoiled, a single strand of DNA would stretch to about six feet, five inches long, so it sounds like we're packed pretty tight up in there. I. Right, right now, consider that there are about 50 trillion cells in your body.
So if you laid end to end all the DNA strands in your body, that would stretch to the sun. And not just once,
[00:04:05] Jordan Harbinger: but 600 times. Okay? So that's obviously incredible, but I can't really wrap my head around it because the sun is super far away. Look, science
[00:04:15] Michael Regilio: and reality do not care what makes sense to you and I or even to scientist to put it in modern parlance facts don't care about your feelings.
The function of DNA is to tell amino acids how to line up into the correct protein shapes. Proteins combine to make cells, cells combine to make up tissues. Tissues make up organs, and organs make up living creatures. The entire process as magical as it seems, is all just. Chemistry, it can be studied, it can be understood.
And that understanding took many people over a hundred years since we first spotted DNA to really figure out. And of course, there's still a lot to be explored. So when was this all first discovered?
[00:04:55] Jordan Harbinger: When did people find out that we even had DNA?
[00:04:58] Michael Regilio: DNA was first discovered in 1869 by a Swiss biologist named Friedrich Meher.
Meher was studying white blood cells and he had a nice supply of white blood cells because he would collect all the used bandages from a nearby hospital.
[00:05:12] Jordan Harbinger: Ah, that's disgusting. Okay, so collecting used bandages from strangers in a hospital. This guy, he must have really loved science. Or used bandages.
[00:05:23] Michael Regilio: Oh man, that is super gross.
Okay, well, it's about to get grosser because Misha was studying white blood cells, which were hard to extract from a healthy person, but were in great abundance in the pus
[00:05:33] Jordan Harbinger: on used bandages. Oh, wow. Now I'm glad I didn't eat before this. Apologies to anybody who's listening to this during lunch right now as we talk about this dude's pus collection.
[00:05:42] Michael Regilio: So he wasn't really collecting used bandages as much as he was collecting the puss on used bandages. And in studying the pus, he experimented and isolated a new molecule he called nucleon and studied it using now from puss to salmon sperm, which might not be exactly as gross as the pussy bandages, pus, caviar, anyone.
And so today we call Nucleon nucleic acid. This is one of the building blocks of life. Almost a hundred years later in London, a scientist named Rosalyn Franklin discovered the double helix shape that we're so familiar
[00:06:16] Jordan Harbinger: with of DNA. So hold on. I thought I remembered that Watson and Crick discovered the double helix thing.
Franklin,
[00:06:23] Michael Regilio: although she was appreciated, her day was largely overlooked for her contributions to the understanding of DNA. And most of the credit went to Watson and Crick because men,
[00:06:34] Jordan Harbinger: right? They say history repeats itself. And I will say that whenever the question of why was this woman or these women overlooked, their accomplishments were overlooked, the answer is almost always because her work just didn't count until a dude came along and took credit for it, which is not cool.
[00:06:48] Michael Regilio: Yeah, look,
[00:06:49] Jordan Harbinger: let's not overlook Watson Andrick. Now. These were also good scientists doing good work. Anybody that watches crime shows or likes a good detective novel knows that the understanding of DNA has been an absolute game changer for solving crimes exactly. Before DNA
[00:07:04] Michael Regilio: law enforcement had a few tools at their disposal.
They were actually pretty imprecise starting in the 1920s with blood typing. Scientists identified four different types of blood, A, A, B, B, and O. This was huge for doctors because they could now safely perform blood transfusions, but it also came in handy for law enforcement. So to catch the bad guys, yeah.
No, actually just the opposite. To free the good guys, you could prove somebody definitely was not the crook if there was a blood sample and the suspect did not have that type of blood, but law enforcement could not use it to help identify a suspect beyond a reasonable doubt,
[00:07:41] Jordan Harbinger: right? Because there are only four blood types, you couldn't do any better than to say that there's a certain percent chance that somebody's the bad guy.
[00:07:48] Michael Regilio: And that's far from enough evidence to convict somebody of a crime. But DNA testing has turned that percentage up like way up, like 99%
[00:07:56] Jordan Harbinger: accurate and higher. And this time, not just for exonerating, but I'm guessing also for convicting. Exactly. In fact, the first
[00:08:04] Michael Regilio: use of DNA evidence in a crime did both. It all started with Alec Jeffries, a professor and geneticist in the UK in the 1980s.
In his research, Jeffrey Study of the humid family revealed that children had a composite of both their mother and father's DNA, and this finding was widely reported in the press. I. A lawyer read about it and he was working on an immigration case and saw the story, and he thought it would be helpful with a client who was having trouble proving his identity.
Professor Jeffries, using the mother's DNA, was able to prove his client was who he said he was. And police took note of this. So that was a, at the time, quite a breakthrough, I'm guessing? Yeah, and it opened the doors for criminal investigations. So in 1986, investigators asked Jefferies to help with a murder case.
Two 15-year-old girls had been sexually assaulted and murdered. A teenage boy with learning disabilities had been arrested and had confessed to one of the murders, but not the other. The police wanted help pinning both murders on the boy and went to Jefferies. And guess what happened
[00:09:04] Jordan Harbinger: based on the fact that you already said this first case, both the bad guy and exonerated an innocent person.
I'm gonna guess the DNA proved that this kid was not the murderer.
[00:09:13] Michael Regilio: Now with no suspects, the cops and Jefferies began to collect DNA samples from local men, but they came up with no matches.
[00:09:21] Jordan Harbinger: You can tell this was the UK because I'm pretty sure in America, the police can't just run around demanding everyone's DNA until they find the right guy.
[00:09:28] Michael Regilio: Oh, yeah. That gets us into all the ethical questions that we're gonna get into in a second surrounding DNA, but yes. This was the UK in the eighties, and there were no laws around DNA sampling. Yet the cops had no leads in this murder case until someone overheard a local baker named Colin Pitchfork bragging that he had submitted a friend's DNA.
So the cops grabbed the dude and he was the perfect match.
[00:09:51] Jordan Harbinger: Wow. Okay. I'm glad they caught him. Right, but what a freaking moron. And his last name was Pitchfork, which is kind of on the nose for a villain. Yeah, they brought out the torches
[00:10:01] Michael Regilio: and pitchforks for pitchfork and he went down and DNA evidence became a thing.
'cause in truth, it actually took years for American Courts to figure out how and when it was acceptable to use DNA evidence. There were ethical questions that needed to be addressed. If they're going to be databases of people's DNA, then those databases and laboratories had to then meet the standards that were established.
But. There was no getting around it. This was a huge leap forward as DNA evidence enabled law enforcement to solve cases that had gone cold decades ago. The DNA Identification Act of 1994 authorized the FBI to create a national DNA database that compares DNA found at crime scenes to the DNA of violent offenders.
[00:10:45] Jordan Harbinger: I understand the ethical questions that come with DNA evidence, but on the whole, I mean, that kind of seems like a win, right? You're a violent offender. You put your DNA in a database. And then they find all the other people that you killed or attacked or whatever.
[00:10:56] Michael Regilio: Yeah, it was a huge win and TV writers everywhere, rejoiced and mic drop moments were unleashed on a hungry public.
[00:11:02] Jordan Harbinger: Yes. It sounds like Professor Jeffries should basically be getting royalty checks for every episode of Law and Order or NCIS or whatever. Yeah.
[00:11:10] Michael Regilio: TV writers had plenty more to write about as real science continued to catch up with science fiction. The next big achievement came with the mapping of the human genome in 1990.
[00:11:21] Jordan Harbinger: I remember that. That was a really big deal, and it really doesn't sound like that long ago, but again, as always, I'm old now.
[00:11:28] Michael Regilio: Yeah, and it was a really big project, like a really big project. The project was headed by Francis Collins and it took 13 years and sequenced 3 billion chemical pairs and maps all the genes
[00:11:40] Jordan Harbinger: encoded in human DNA.
Okay, so it seems like a pretty good time to ask what's the difference between DNA and genes.
[00:11:49] Michael Regilio: Short answer, genes are segments of your DNA. Those segments. Genes are responsible for our unique physical characteristics. In short, genes are the units of hereditary traits and contribute to the traits and organism inherits from its parents.
DNA is the complete string of these segments all strung together in a double helix.
[00:12:11] Jordan Harbinger: Okay, so stop me if this is derailing us too much, but what is cloning? I know I've heard of that. When it comes to DNA.
[00:12:17] Michael Regilio: Okay, let's start by differentiating between cloning plants and animals. Many plant cells are to tippit, meaning each cell has the potential to regenerate into a whole new plant.
Very often cloning a plant requires little more than just snipping a branch and allowing it to grow into a whole new plant. Cloning animals is different. That is when scientists make an exact copy of something using its DNA. That is to say no sex needed. Some organisms already do this in nature like starfish, which can regenerate an entire new body from just an arm.
Most animals can't do this, but with a scientist's help, just about any living thing can make an exact copy of itself. In 1996, scientists in Scotland successfully cloned a sheep named Dolly. Oh, I remember that
[00:13:03] Jordan Harbinger: too. That was huge news. Dolly
[00:13:06] Michael Regilio: was the only lamb to survive out of 277 attempts.
[00:13:09] Jordan Harbinger: I mean, that sounds like cloning is pretty hard.
You gotta hand it to them for not giving up though. After 200 dead lambs, I might be like, Hey, this is not working.
[00:13:16] Michael Regilio: Yeah. In fact, until Dolly, many scientists believe mammals just couldn't be cloned. But they can. In fact, right now, there are companies that can clone a pet for you. If your favorite kitty dies, you can literally get them back.
And once again, a panoply of ethical questions have arisen.
[00:13:35] Jordan Harbinger: Oh yeah. I don't know how I feel about that. So can humans be cloned? That's the obvious Next question here.
[00:13:40] Michael Regilio: In truth, the bigger question is, should humans be cloned? And the answer is yes. We think primates have already been cloned and researchers in South Korea and Michigan have cloned a human embryo.
But that was only for research purposes. Countries are passing laws about human cloning. Like all things DNA is mired in ethical questions. You know,
[00:14:01] Jordan Harbinger: it's almost as tasty as a collection of pussy used bandages. I. Define products and services that support this show. We'll be right back. This episode is sponsored in part by IQ Bar, our exclusive snack sponsor.
I've been instructed to tell you I've been extra focused on my fitness and nutrition goals. If you haven't noticed, and if you wanna achieve goals, counting macros is really the key to staying on track. So whether I'm working on losing fat, building muscle, or just maintaining, hitting the right balance of protein, carbs, and fats is not always easy, especially with a busy schedule.
That's why I keep IQ bars close by. The bars are packed with protein and fiber. They're low in sugar and carbs, and they actually taste good. A lot of times these bars, you know, they taste like cardboard. Whether I'm grabbing a chocolate sea salt bar to start my day, or a peanut butter chip for an afternoon boost, I know I'm fueling my body with quality ingredients, no junk.
They're gluten-free, dairy-free, soy-free. And free of artificial sweeteners. I'm already soy enough I guess, according to many of you. Basically all the good stuff, none of the bad. But IQ Bar is not just about the bars. They've got IQ mix, which is zero sugar hydration mix, packed with electrolytes, magnesium to boost mood, lion's mane for mental clarity, you know, all that trendy stuff.
And IQ Joe is a great jitter, free caffeine with lion's mane and magnesium, which is a good way to start the day, especially if you don't wanna drink a bunch of coffee like the rest of us.
[00:15:14] Jen Harbinger: Now IQ Bar is offering our special podcast listeners, 20 person off all IQ bar products, plus get free shipping. To get your 20 person off, just text Jordan to 64,000 text J-O-R-D-A-N to 64,000.
That's Jordan to 64,000. Message and data rates may apply. C terms for details.
[00:15:33] Jordan Harbinger: This episode is also sponsored by Shopify. It's 2025. So let me ask how long you've been sitting on that business idea. You know the one you think about all the time, but you haven't started yet. Don't get stuck. Overthinking, second guessing, and then regretting, not starting sooner.
Shopify makes starting a business ridiculously simple. You get access to Shopify's customizable template, so you don't need to be a coding wizard or design guru. Just drag drop and voila, that's French. You've got a professional looking online store that's open for business, and Shopify doesn't just stop at, set it and forget it.
They actually wanna help you grow their social media tools, let you turn, scrolling into sales, connecting your products with people wherever they hang out online, and they handle the not so fun stuff. Shipping, taxes, payments so you can focus on your big ideas. Instead of figuring out tax brackets, and if you don't start now, will you regret it?
That I think they're implying that you will. Will someone else beat you to the punch again? I think they're implying that they will. Shopify helps you take action and your first sale is closer than you think.

Again, Jordan harbinger.com/news. Alright, back to Skeptical Sunday. All the hilarious dad jokes aside about how I could use a clone of myself, it does seem really dicey and hard to put that genie back in the bottle, but I kind of assume places like China are doing this.
And in a way, actually I hope they are because I'm dying to know how this all plays out.
[00:17:20] Michael Regilio: Yeah, look, we'll get to China in a minute because they are players here, but each of these developments raises a new set of ethical questions. Genealogical databases, that's where tons of private health information is stored.
They could be hacked by bad actors. And I don't mean like Nick Cage, I mean somebody leaks your DNA on the internet and now insurers don't want to cover
[00:17:42] Jordan Harbinger: you because you're prone to
[00:17:43] Michael Regilio: cancer or whatever.
[00:17:43] Jordan Harbinger: To be fair, Michael, that does sound like the plot of a movie with a script that Nick Cage would say yes to, like
[00:17:50] Michael Regilio: that is so true.
And you know what I. I saw, what was that? I, I saw his movie Pig recently and it was really weird and good. It's about, anyways, I haven't seen,
[00:18:01] Jordan Harbinger: I haven't watched anything since my kids were born other than Coco Melon.
[00:18:04] Michael Regilio: Okay. I haven't heard of Cocoa Melon yet, but yeah, don't worry about
[00:18:08] Jordan Harbinger: it. It's a cartoon that repeats.
Sing songy stuff over in. Yeah, I don't wanna talk about it. Yeah. Look, Nick Cage basically just shrugs and says, sure to every script that slides across his desk. That's I'm convinced.
[00:18:21] Michael Regilio: Yeah. You know what? If he's working that hard, maybe he could use a clone of himself. But look back to the ethical questions like the genetic counseling, which could arise as we enter this brave new world that could turn easily into eugenics and eugenics in case anyone doesn't know.
Is an attempt to create a superior gene pool and it is widely condemned as racist, ableist, and in violation of human rights. And if you needed any more evidence that it's a bad idea. The most famous champions of eugenics were of course, the Nazis.
[00:18:52] Jordan Harbinger: Okay, got it. So eugenics, bad idea.
[00:18:55] Michael Regilio: Right? And I don't know if this company is a sponsor, but I have to say my jaw was on the ground when I first saw commercial for a company that has a product called Eugenics.
So definitely eugenics. Bad. Don't even talk about it. So personalized medicine, look, as we head into this brave slash weird new world personalized medicine could then eventually equal one quality of care for the rich and another one for the poor. You mean like healthcare is right now in America basically?
True. And here's a really scary one. How about biological weapons that target individuals? Whoa, that's sci-fi crazy talk. Is that actually possible? That's actually, yeah, that's a real possibility. And the idea here is to use DNA to create weapons that exploit the genetic differences between ethnicities.
Obviously, most weapons research is secret, but rest assured, DNA targeting as a weapon of war is something that's being developed.
[00:19:53] Jordan Harbinger: Yes, everyone rest easy knowing that DNA bombs or whatever they can wipe out entire population groups might be in your future. I.
[00:20:01] Michael Regilio: Let's take a little break from the dark stuff and talk about the fun aspects of DNA, figuring out who our great grandparents banged.
[00:20:09] Jordan Harbinger: Yeah. Everybody loves to find out about their ancestry, actually. Maybe almost everyone. There's definitely some exceptions to this rule, for sure. Yeah. Like racists who find out that they're not quite as white as they thought they were. Oh yeah. No, that, but that's rich though, that everyone straight into my veins with that one.
Yeah, but it is fun.
[00:20:27] Michael Regilio: In fact, tracing the old family tree through home genetic tests is so fun that it's a $3 billion a year industry. And
[00:20:36] Jordan Harbinger: I have to ask, have you done it? I have. I've done, I won't say the name because when they get hacked, I don't want people looking for my DNA or whatever, but I. I've done one of those, or a few of those.
I also hired somebody else to trace my family way back. And you get messages on the website sometimes where it's like, I think we're related. And I'll tell my mom and she's like, don't reply. They're probably nuts. Just like everybody else on our side of the family, I. And we did find out that my grandfather on my dad's side basically had a secret family before he had my dad's family.
But I guess back then when you got divorced, you just never talked to that family ever again and pretended they didn't exist. That was what you did.
[00:21:12] Michael Regilio: Wow. Yeah. I mean, that's what DNA does. It's uncovering family secrets. In fact. There's a really interesting story. There's an actress, Kerry Washington, and she tells this really heartwarming story of when she was asked to be on the show Finding Your Roots.
Do you
[00:21:26] Jordan Harbinger: know the show? I think I've seen It's like an airport lounge watch. Yes. They run DNA tests on celebrities and then reveal their true roots, and it's fun and surprisingly not trashy.
[00:21:37] Michael Regilio: So was asked to be on the show, and as such, she needed her parents to also take a DNA test and her parents freaked out.
She comes to find out that her father couldn't have children and her parents used a sperm donor, but never told her. Ah, okay. That must
[00:21:53] Jordan Harbinger: have caused a little bit of strife.
[00:21:55] Michael Regilio: No, actually, the way she tells it, it's like it's strengthened her relationship with her father. As you realize that her dad really wanted to be her dad.
Like he chose to go through the hurdles and emotions of using a sperm donor. It actually made her feel closer to him. So it's a sweet story. Yes. But DNA. Home tests aren't all sweet stories. As we've talked about. There are so many concerns.
[00:22:17] Jordan Harbinger: Yeah. I heard as we mentioned earlier, that there are risks involved in having your DNA just out there in a database floating around, waiting to be hacked or used by bad actors like Nicholas Cage.
[00:22:28] Michael Regilio: Yeah, for sure. Although the Affordable Care Act AKA Obamacare, yes, Obamacare makes it illegal for health insurance companies to deny you coverage or charge a different rate. They can still ask about the health of a customer, but health insurance isn't the only insurance or even. The only institution interested in what's in a person's genetic code, like life insurance, I'm guessing.
Sure. And there's also disability insurance, not to mention banks might be very curious about the health of the person they're about to give a loan to.
[00:23:01] Jordan Harbinger: Yeah, that makes me even more hesitant to take a test, although I'm probably too late for having done a couple of these already. So how secure is this data?
[00:23:09] Michael Regilio: Okay, so these companies are aware of these threats. In fact, in 2018, my heritage.com experienced a breach affecting email addresses and passwords, but not genetic data thanks to their separation practices. That is to say the customer's name and information is in a different database as the genetic information.
Genetic testing companies claim they all take extra care to separate the customer's identity from their genetic information. But. Once it's in the customer's hands, the onus is on
[00:23:40] Jordan Harbinger: you
[00:23:41] Michael Regilio: to protect it.
[00:23:42] Jordan Harbinger: When I think of how often my laptop says it's detected spyware, it just doesn't leave me with a lot of confidence.
[00:23:48] Michael Regilio: Yeah. Here's the thing, Jordan, you could never take a genetic test and your genetic info could still get out there. How? How is that possible? Because you are not the only one walking around with this hereditary data in your cells. Everyone you're related to has the same info to varying degrees.
[00:24:07] Jordan Harbinger: Oh yeah. I did not think of that.
So if both my parents took a test, they basically say, well smash these together. There's Jordan.
[00:24:15] Michael Regilio: Yeah. Or how about a sibling who has the exact same two parents and therefore the exact same hereditary information. You can learn a lot about someone by studying relative's. DNA just asked the Golden State Killer, that's how they nabbed him.
They found a close relative of his through a genetic database and found him almost immediately.
[00:24:35] Jordan Harbinger: That's right. We did a episode with Paul Holes, one of the guys that caught him, and that's episode 7 25, and they basically. Yeah, I think they found his brother or something like that, and he was a close match, but it couldn't have been him.
And they were like, wait a minute. This person is so close. Who else could it be? It's gotta be related to him. Oh, he is got a brother who's a police officer, and that was the Golden State Killer. Not exactly the poster child for genetic privacy rights, but it does illustrate the risk.
[00:24:59] Michael Regilio: Yeah. In fact, prospective employers might also like to know who they're about to offer the big job to.
Is
[00:25:05] Jordan Harbinger: he a notorious, most wanted
[00:25:07] Michael Regilio: serial killer or not? Or just is he going to get really sick in the next couple of years and maybe he's not the guy to give the job to. This is scary stuff. It's almost like having a crystal ball. It's definitely not something that you want out there in the world. It is private information.
So brave slash weird new world. Brave old world too. 'cause genealogists can now trace our earliest ancestors' diaspora from Africa to the furthest corners of the world. Turns out that we didn't need written records of the ancient past. The story of the human species is written in our DNA. That's how scientists discovered Mitochondrial Eve.
[00:25:46] Jordan Harbinger: Mitochondrial Eve sounds like a holiday for a very specific type of nerd. I
[00:25:51] Michael Regilio: love that joke. Mitochondrial Eve refers to the most recent common ancestor of all living humans traced through maternal lineage. A single woman estimated to have lived in Africa around 200,000 years ago. And because mitochondria is only passed through the mother, we can trace everyone's existence back to this one.
Woman.
[00:26:14] Jordan Harbinger: Wow, that is wild. So we all have the same great whatever grandmother. So the best history books really are written inside ourselves. How cool is that? Yep.
[00:26:24] Michael Regilio: See, it's even written in the DNA of our hominid brothers and sisters. That didn't make it. So I was gonna make a joke about don't pour 40 out.
Okay, nevermind.
[00:26:34] Jordan Harbinger: Pour 300 million forties out for our homies.
[00:26:38] Michael Regilio: But that's because scientists have mapped the DNA of Neanderthals with one sample taken from a 38,000 year old Neanderthal in Croatia and great-great-great grandma may not have kissed and told, but the DNA doesn't lie. Humans and Neanderthals bred with each other around 65,000 years ago.
[00:26:57] Jordan Harbinger: Oh man. I guess calling somebody in ne Enderol is not the insult that we thought it was. It's got a kernel of truth. Right. Yeah, exactly. You might just be being accurate
[00:27:06] Michael Regilio: if you call somebody that that's part that's pretty damn fascinating actually. Yeah. DNA is pretty damn fascinating. Our understanding and ability to manipulate it is a game changer.
For instance, genetic engineers can modify the DNA of the plants we eat to improve diets and food distribution. So GMOs basically. Yeah, look, I obviously that is its own episode, but everything was genetically modified long before we had a word for it. That's what farmers have been doing for thousands of years.
Bottom line, as we look ahead at the changes our planet is undergoing, we are going to need this technology to create drought and disease resistant crops,
[00:27:46] Jordan Harbinger: or the world could come together and implement meaningful changes to stem, the worst effects of climate change. Yeah, I'm, I'm kidding. That'll probably never happen, and we should probably be open to technology that solves parts of this
[00:27:57] Michael Regilio: for us.
And plus, through DNA, doctors can create truly personalized care for patients based on their individual DNA, because we're all genetically different. Well, I. Technically, we're actually pretty darn similar. Humans are 99% genetically the same, but that little 1% does a lot of work to make us unique, but even that could change as we face the realities of gene
[00:28:21] Jordan Harbinger: splicing through crispr.
So tell us what CRISPR is again, I think a lot of people have heard of it. A lot of folks might not know what that is. It was a massive
[00:28:29] Michael Regilio: leap forward for humanity. It made the cover of magazines, newspapers, and won the Nobel Prize. For the two scientists who discovered it, and I only mentioned this because we talked about how Rosalyn Franklin was initially denied credit for her contribution to our understanding of DNA.
These two scientists were both women, Emmanuel Sharpen and Jennifer Doudna, and like so often in science, they made this discovery by accident.
[00:28:54] Jordan Harbinger: I always find that so interesting. Many scientific discoveries are just made by accident. It doesn't happen as often in other fields. You know, a random accountant was not doing some dry cleaners taxes and is like, oh look, I've invented cryptocurrency.
So what was the happy accident that ended up with us getting the ability to edit DNA?
[00:29:15] Michael Regilio: They were studying how bacteria protects themselves from viruses. This also blew my mind. Bacteria can get sick. Really? How ironic is
[00:29:23] Jordan Harbinger: that? Yeah. I'm just telling you what I learned. So basically my infection can get an infection, which is crazy.
Okay, so you said CRISPR is gene splicing. Tell us what that is exactly.
[00:29:35] Michael Regilio: It's gene splicing or gene editing. In short, while studying bacteria, these scientists discovered that bacteria have a part of their DNA called crispr, which stands for clustered regularly, inner space. Short palindromic repeats.
Palindromic like a palindrome like the word race car. I think so. And just as a total aside, my favorite palindrome is go hang a salami. I'm a lasagna
[00:29:58] Jordan Harbinger: hog. So palindromes are when it's the same, when it reads the same backwards and forwards. A race car is the same backwards and forwards and apparently so is go hang a salami.
I'm a lasagna hog, which is, you gotta wonder how they figured that one out. That's. Almost as impressive as discovering the ability to edit genes while looking for something else.
[00:30:16] Michael Regilio: You talked about these very specific kind of nerds that celebrate mitochondrial Eve. I think palindromes are probably discovered by a different kind of very specific nerd.
I think you might be right. Yeah. So this CRISPR stores a tiny piece of a virus's DNA, and the next time the virus comes back, this CRISPR snips out a piece of the DNA and destroys it. So these two scientists wondered, why can't we use that technique to cut? Out genes that are unwanted and replace them with ones that are wanted.
You know what comes with
[00:30:46] Jordan Harbinger: absolutely no ethical dilemmas supporting the fine products and services that support this show. We'll be right back. This episode is sponsored in part by Better Help. What's your story for 2025? Is it gonna be the year you make real changes or is it gonna be another chapter of, uh, I'll figure it out later?
We've all been there, but seriously, the new year is not just about resolutions that fade, it's about rewiring the tough chapters and building something that actually lasts. Therapy for me personally, has been huge and for everybody I know who's into it, and by the way, I find out when I start talking about it, a lot of people are like, oh yeah, I do therapy.
You do therapy. It's like this weird secret, especially among guys, I don't get it. Come on, do it. It's good for you, for God's sake. Then again, so are vegetables and I don't really indulge anyway. I didn't mess with therapy for a long time. Therapy though. Not for when things just go sideways. Although it can be a lifesaver then too.
It's like having a GPS for life, helping you avoid dead ends. Navigate the tricky stuff. Figure out where you really wanna go, and better help is good. They make therapy so accessible. It's almost impossible to make excuses. It's completely online. It's affordable. It connects you with over 30,000 licensed therapists.
You can do sessions via video, phone, even text, which means you can literally be in sweatpants. Still be working on yourself. And here's the best part. If your therapist is not the right fit, because not everyone's a match, I've dumped a few in my day. You can switch at no extra cost.

It's the location and neighborhood. So if you've got kids, it's also schools nearby parks, transportation options. That's why homes.com goes above and beyond to bring home shoppers the in-depth information they need to find the right home. And when I say in-depth, I'm talking deep. Each listing features comprehensive information about the neighborhood complete with a video guide.
They've also got details about local schools with test scores, state rankings, student to teacher ratio. They even have an agent directory with the sales history of each agent.

Now, for the rest of skeptical Sunday, this, this is fascinating. 'cause I always thought, oh, gene editing, it's like some machine that does a bunch of specific things and I'm sure there's machinery involved, but really this is a natural process.
They're using a natural process to edit DNA, which is. Wild to me. Okay. So they're cutting out jeans that are unwanted, replacing them with jeans that are wanted and do you mean in humans in anything?
[00:33:26] Michael Regilio: As I said, this is a huge leap forward and as such, this technology comes with a huge ethical concerns.
Have you
[00:33:33] Jordan Harbinger: seen the film Gatica? Yes. A classic Ethan Hawk and Uma Thurman. I love that movie. It's a dystopian,
[00:33:40] Michael Regilio: futuristic tale in which society is divided not by race or nationality or religion, the classic dividing line, but rather by genetically enhanced humans and non-genetically enhanced humans.
[00:33:52] Jordan Harbinger: Yeah.
Such a good movie with su. It's got a super cool aesthetic that I can't really describe because I don't know anything about movies, but it's sort of like. It's 1939, but it's also a hundred years ahead in the future. At the same time,
[00:34:04] Michael Regilio: no. Yeah, it's a great movie. I love the film thanks to crispr, that future is now.
That's what this technology could and I emphasize, could do, how scientists could manipulate an embryo and turn off the genes for genetic diseases and turn on the genes for intelligence, athleticism, and a myriad of other desirable traits. This. Is where the debate comes in. You see there are two kinds of cells in the human body.
There are somatic cells in germ cells altering one or the other has different ethical implications. So you're gonna
[00:34:40] Jordan Harbinger: need
[00:34:40] Michael Regilio: to
[00:34:40] Jordan Harbinger: explain
[00:34:40] Michael Regilio: that to me, okay? If you go to an adult and change their somatic cells, these are genetic changes done to an adult with their consent and the changes you make to them genetically cannot be passed on to their offspring.
Okay, I am think I'm following so far. So changes to somatic cells in an adult come with no real ethical dilemmas. In fact, it's already been done. Take the case of Victoria Gray. Victoria was born with a blood disease called sickle cell. It's a pretty brutal disease that both compromises the quality of a person's life and can dramatically shorten it.
For the first time ever, doctors used CRISPR to treat the disease. Doctors infused Victoria with more than 2 billion of her own bone marrow cells. That had been edited with crispr. That is to say they had cut out the gene for the disease. Wow, that's amazing. I. Yeah, and it worked. Almost all of her symptoms are gone.
Victoria is enjoying her life in ways she never could have hope for before crispr.
[00:35:40] Jordan Harbinger: Okay, so no ethical dilemma there. And by the way, I'm so curious. How do you know if the DNA is in every cell in your body? How do you know which DNA you have to change to get it to work? There's gotta be some sort of chain reaction.
Oh, if we change one bit of DNA in some cells here, it just spreads and then you don't have this anymore.
[00:35:56] Michael Regilio: And I'm so curious. Right. I wish I had an answer for you on that one. Although I do know that in my research that blood diseases are one that they're really optimistic that CRISPR can be a game changer for.
So there's something about blood diseases that they think is particularly optimal for using crispr.
[00:36:13] Jordan Harbinger: I have no idea how long it takes to refresh all your blood cells. I know it's different for different types of cells and some never completely refresh like fat cells, but. It makes sense that blood would be something where they can reasonably say, Hey, by the way, your defective blood is gonna be largely gone within a few weeks, months, or whatever.
[00:36:30] Michael Regilio: I have a list of four reasons why blood diseases are particularly easy to treat with crispr. Number one, accessibility of blood. Number two, well-characterized genetics. Many blood diseases such as sickle cell anemia are caused by a single gene mutation, established transplant procedures and rapid cell turnover.
[00:36:50] Jordan Harbinger: So basically because of rapid cell turnover, and I'm, again, I have no idea what I'm even talking about here, so let's continue.
[00:36:57] Michael Regilio: The dilemma comes from the other changes that could be made, changes to the germ cells, which are changes made to an embryo. That procedure comes with a host of issues.
[00:37:07] Jordan Harbinger: I'm guessing.
One issue in this case is that the person being altered has absolutely no say in the matter because they're not born yet. I. You nailed it. The
[00:37:14] Michael Regilio: other is that these changes can be passed on to offspring. Since this technology is new, scientists can't be sure what unforeseen consequences might arise to do it is to literally experiment on people who had no say in whether or not they wanted to be experimented on.
[00:37:32] Jordan Harbinger: That seems like an issue that requires a bunch more research before it should be done at all.
[00:37:37] Michael Regilio: But, and this is a huge, but it's already been done. It has, yep. This is the Tale of Haji and Quay, a Chinese researcher who stunned the world when he announced that he had produced genetically edited babies.
[00:37:53] Jordan Harbinger: Babies like the plural of babies. So more than one baby has been genetically edited by this guy in China. Yep. Three babies, a
[00:38:01] Michael Regilio: set of twin girls and another child. In November, 2018, he announced that he had genetically altered a number of human embryos in a way he believed would give them resistance to HIV.
He made the announcement at the International Summit on human genome editing in Hong Kong, and I'm not sure what he thought the reception would be, but if he was hoping he'd be heralded as a hero, he was wrong. His colleagues went, and this is a scientific term ape shit.
[00:38:29] Jordan Harbinger: Yeah, I can only imagine. Talk about opening Pandora's box and see I told you that Chinese were probably doing something with this ethics aside.
I'm actually still dying to hear how this shakes out. And it's amazing, even if it is totally unethical from a medical, scientific, moral, whatever, perspective.
[00:38:48] Michael Regilio: Here are some of the problems. Fellow scientists pointed out that there are safer, less potentially disastrous methods for protecting people from HIV.
And of course, there's the whole issue that he just blasted right past the ethical concerns without so much as even conferring with his scientific peers. This was maddening.
[00:39:06] Jordan Harbinger: It definitely seems like a strange move. Rogue scientists, they don't exactly have a great reputation in history or even fricking fiction for that matter.
You know, I'm something of a scientist myself.
[00:39:19] Michael Regilio: Yeah. The story of Dr. Frankenstein isn't really a story of what to do, and the Chinese government wasn't exactly thrilled to have been embarrassed on the world stage by him, so they arrested him. He was convicted of illegal medical practices and sentenced to three years in prison.
I feel
[00:39:37] Jordan Harbinger: like if people were like, wow, this is amazing. China would've been like, yeah, cool. Yeah, we did it. But since everybody was like boo, they were like, oh man, you're gonna have to fall in the sword for this one buddy.
[00:39:46] Michael Regilio: Yeah. And look, in his trial, it was claimed that he had falsified paperwork, that he hadn't been completely honest with the people that were donating the embryos.
I. And the Chinese government has definitely distanced themselves and said, we've had nothing to do with this. But I also dunno that I trust the Chinese government to be completely honest with us on everything.
[00:40:06] Jordan Harbinger: So they arrested him and then what? Is he still in prison? No, I think he's out. What about the kids?
He experimented on? How are they doing?
[00:40:13] Michael Regilio: That's not clear because understandably they're not in the public eye. But for better or worse, the Chinese government now has three test studies on the long-term effects of designer babies, and now we've entered a brave, or at least a weird new world, I.
[00:40:29] Jordan Harbinger: Hopefully for the better.
What's really gross and scary to me, and I really hope I'm wrong about this, there's kind of only one real foolproof way to test if a baby that is supposed to be resistant to HIV is actually resistant to HIV, and that is to try to infect them repeatedly and deliberately with HIV. And I really hope those babies in China are not being jabbed with HIV needles on a regular basis just to see if they get a horrible, potentially fatal disease.
I.
[00:40:57] Michael Regilio: Legit, that is a legit concern. But in this case, what happened was the father donor actually, 'cause I looked into this, he was HIV positive, the mother wasn't. So what the scientist was trying to do was create them resistant from the get-go. They kind of were exposed to HIV in the womb. There's another thing where when the cells separate, as we do, when you have an embryo, and it begins separating where scientists were concerned that some.
Of the cells could be genetically altered and others could not be. And so you could end up with a person who's half their organs or half of their cells are genetically resistant, the other half aren't. Again, he jumped the gun. He should not have been doing this. There was way more research to do. In addition, there are people who are born with a natural resistance to HIV.
So this scientist was simply turning on the genes in these babies that some people already have. Look, 75 countries already prohibit the use of CRISPR in human reproduction, but I think we'd be naive to think we can put the toothpaste back in the tube on this one. We really think Kim Jong-Un or Vladimir Putin are going to be restrained by ethical questions in the face of making an army of super soldiers.
[00:42:06] Jordan Harbinger: Yeah, I think those super soldiers would first need working weapons, ammunition, and if they make 'em really smart, they might be like, I am not gonna fight for this authoritarian nonsense regime. And in the case of North Korea, they need food. But yeah, see your point.
[00:42:20] Michael Regilio: I. Yeah, it's a totally legit concern.
Authoritarian states could potentially misuse DNA data on their citizens, like for surveillance and tracking. We mentioned Gatica in that film, there was technology that vacuums up all the dead skin cells. We leave everywhere.
[00:42:35] Jordan Harbinger: Yeah. 600,000 a day. And I do definitely remember Ethan Hawk furiously vacuuming his computer keyboard at the end of every workday and then opening a vial and sprinkling other skin cells on it so that they would find them.
Yeah.
[00:42:49] Michael Regilio: In fact, he started every day by like using a pumice stone to get all those dead skin cells off of him, or as many as possible so that he wasn't leaving a trail of skin cells. Because that's just what we do. We leave a dead skin cell trail everywhere we go. In the film, the technology is such that they can instantly identify whose cells they found.
That speed of identification is not a science reality yet, but it is a reality that that identification can be done. And as to the speed.
[00:43:17] Jordan Harbinger: It's coming. Yeah. Why is it always the scary tech in sci-fi movies? That becomes reality and we still don't freaking have hoverboards, man, come on. Yeah, I
[00:43:25] Michael Regilio: hear you on that one.
Totalitarian states could use DNA to discriminate against certain ethnic groups. This can lead to a systemic exclusion, detention or worse. Plus DNA data might be used to create profiles of individuals deemed likely to commit crimes based on their genetic markers.
[00:43:43] Jordan Harbinger: Yeah, so see, that's really scary. It reminds me of Minority Report with Tom Cruise, but instead of ESP, they're using DNA, and either way they're using an acronym to oppress people.
[00:43:55] Michael Regilio: Yes, look, welcome to the future. These potential uses illustrate the importance of strict regulations and safeguards to protect genetic data and prevent its misuse. Then again, when has there ever been a technology that someone somewhere wasn't willing to mess with, no matter how dangerous, and here I was killing Goode about the promise of crispr.
Me too. Look, progress always comes with questions and scary worst case scenarios, including the human race, gaining access to the blueprints of life and developing the ability to mess with them. Who knows what the distance future may hold. Maybe people will become genetically altered to live on Mars or a moon of Saturn.
Maybe we can remove the genes for mental illness or cancer. I'm an optimist, a skeptical optimist. This understanding of DNA and how to manipulate it has already done so much good.
[00:44:46] Jordan Harbinger: I agree. Hey, we talked about the kid who was exonerated in that first case of DNA evidence. But he was just the first of many lots and lots of innocent people have been freed from wrongful convictions, from DNA evidence.
[00:44:58] Michael Regilio: Plus millions of people now get to add a whole ton of new ethnicities to their dating profiles. Yes, that's
[00:45:04] Jordan Harbinger: right. Those are the real heroes of the podcast. I'm 0.4% yakut, by the way. That's
[00:45:11] Michael Regilio: true. Wow. Them are some bragging rights. It's clear we stand on the brink of unprecedented possibilities from curing genetic disorders and enhancing human capabilities to ethical dilemmas and unforeseen consequences.
The power to edit our genetic code opens a Pandora's box of opportunities and challenges. I. As we move forward, it's super important that we balance innovation with responsibility, ensuring that the benefits of genetic advancements are accessible and equitable. Let's stay informed, engaged, and thoughtful as we navigate this brave slash weird new world.

Join us on episode 8 79 to explore the fine line between psychopathy and genius and why being labeled a psychopath might not be the curse.
It seems.
[00:47:06] JHS Clip: Going back to the good psychopath question, I think the key here, that is how you dial those up. It's exactly like mixing a soundtrack in a studio, right? It depends on the combination. In which you dial those straits up. It depends on the level, and it also depends on the intention that you're gonna use 'em for.
If you've got ruthlessness, fearlessness, no conscience, no empathy, all turned up to max and it's stuck there. You are likely gonna be a bad psychopath. However, if you can twiddle those dials in various combinations, depending on the circumstances that you might happen to find yourself in, uh, ruthlessness, fearlessness, mental toughness, self-confidence.
Course under pressure, emotional detachment, lack of conscience, lack of empathy, those kinds of things. Now, none of those characteristics that I've just outlined is necessarily a problem in itself in isolation. All of them in the right context and kind of dialed up at the right levels can actually prove pretty useful, what I call rather controversially, some precision engineer psychopathy.
So you're gonna be what I call a good psychopath. Great quote by the famous British writer, George Orwell. Good men sleep soundly their beds at night because rough men stand ready to do violence on their behalf. Good psychopaths do exist, but it all depends on those dials. It's a very unpalatable sentiment, but unfortunately some people might say happens to be true.
