Speaker 1: Welcome to Stuff you should know from house Stuff Works
Speaker 1: dot com. Hey, and welcome to the podcast. I'm Josh Clark,
Speaker 1: and there's Charles W. Chuck Bryant, and there's Jerry. Jerry
Speaker 1: the placebo do sir? No, No, that was bad, Chuck. Yes.
Speaker 1: Have you ever heard of the word placebo? Do, sir? Yeah? Placebo?
Speaker 1: You know what I mean? I do. Tell everybody I
Speaker 1: shall see, No, I will please, I shall please. That's right,
Speaker 1: met ill see, We'll see about that. I shall please.
Speaker 1: That's what I meant in Latin. Yes, all right, so placebo.
Speaker 1: Everybody's heard of a placebo and very famously the placebo effect.
Speaker 1: You wonder where that comes from? The placebo effect. The
Speaker 1: word placebo um fourteenth century. It referred to hired mourners
Speaker 1: at funerals. What they would hire mourners in place of
Speaker 1: family members, and they would start their morning wailing with
Speaker 1: that mourning. But as in m O, you are with
Speaker 1: placebo domino in region vivorum, which means I shall please
Speaker 1: the Lord in the land of the living. But in
Speaker 1: that it means placebo. Uh. This article said, it carries
Speaker 1: the connotation of substitution. Weird. Yeah, that is fantastic stuff.
Speaker 1: I thought. So this is from Placebo's and Placebo Effects
Speaker 1: in Medicine Colon Historical Overview by Tisson cap Chuck Green
Speaker 1: and Legion Catchuck. That guy is high quality. Oh yeah, yeah,
Speaker 1: a lot of skeptics. He's at Harevard. Let me tell
Speaker 1: you a little bit about Ted Kapchuck. Okay, the coney
Speaker 1: Allen cap Chuck's I just raised a lot of skeptics
Speaker 1: hackles because some people see him as a huckster of
Speaker 1: fraud or everything that's wrong with placebos. These people, um
Speaker 1: would probably have a problem with us even talking seriously
Speaker 1: about the placebo effect in the first place. So I
Speaker 1: don't know that it's a really big deal that I
Speaker 1: just raised their hackles. But Ted Katchuk is a former right,
Speaker 1: let me tell you about capture. Now. He's a former
Speaker 1: acupuncturist and he apparently had some sort of epiphany one
Speaker 1: day when he was he was treating somebody and they
Speaker 1: started to feel better before he even used the acupuncture.
Speaker 1: So he started wondering, like, okay, what's going on here?
Speaker 1: And he started investigating the placebo effect, and in short
Speaker 1: order he ended up as an instructor at Harvard and
Speaker 1: became one of the leading researchers into the placebo effect,
Speaker 1: which is a really strange journey because every medical school
Speaker 1: doesn't usually hire acupuncturists. And he had like kind of
Speaker 1: a rocky road at first, like he didn't know what
Speaker 1: he was doing with clinical trials, and he got publicly
Speaker 1: called out in the New England Journal of Medicine and
Speaker 1: UM over the years, over the decades, I think this
Speaker 1: is the eighties that he really started to look into it.
Speaker 1: He um, like I said, became the foremost researcher in
Speaker 1: in coming up with quality clinical trials for trying to
Speaker 1: get to the root of what the placebo effect is
Speaker 1: and how to use it. What years was that? You
Speaker 1: know he's still doing it, but when was this? When
Speaker 1: he was started all that stuff. He got called out
Speaker 1: and I think a two thousand one issue of the
Speaker 1: New England Journal of Medicine UM basically for not using
Speaker 1: a control group in his placebo study. So you know,
Speaker 1: when you do a study, you have a placebo group
Speaker 1: which is your control group, and that basically is I'm
Speaker 1: giving you real medicine, but I'm giving Jerry a sugar pill.
Speaker 1: And in a proper study, I don't know who's getting
Speaker 1: the sugar pill and who's getting the medicine. It's called
Speaker 1: double blind. Um so in if you're studying just the
Speaker 1: placebo effect, I should be giving you a placebo and
Speaker 1: I should be giving Jerry no treatment whatsoever. To truly,
Speaker 1: I thought you needed three people, one with a real treatment,
Speaker 1: one with placebo, and one with no treatment. It's another
Speaker 1: way to do it, Okay, at the very least, though,
Speaker 1: you need the placebo group and somebody who's receiving no treatment, gotcha. Yeah, yeah,
Speaker 1: if we're skinning cats, well, if you're doing good science
Speaker 1: researching into the placebo effect. But what's ironic is is
Speaker 1: this whole double blind placebo study came about because the
Speaker 1: placebo effect was first noticed by Western practitioner by the
Speaker 1: name of Dr Henry Beecher, who in World War Two
Speaker 1: supposedly saw a nurse give a shot of sailing to
Speaker 1: a soldier because they'd run out a morphine, but the
Speaker 1: nurse told them it was morphine, and the soldier responded
Speaker 1: to this shot of saline like it was morphine, And
Speaker 1: from that Beecher was like, what is going on here?
Speaker 1: Started to investigate the placebo effect and ended up proposing
Speaker 1: the double blind placebo study to prove the efficacy of drugs.
Speaker 1: That goes back further than that, my friend, let's hear
Speaker 1: it man UH try seventy five the New Medical Dictionary,
Speaker 1: they described the placebo as a commonplace method or medicine,
Speaker 1: and then a short time later, in eighteen eleven and
Speaker 1: Quincy's lexicon uh Medicum, he defined the placebo as an
Speaker 1: epithet given to any medicine adapted more to please than
Speaker 1: to benefit the patient, like heroin. So they were on
Speaker 1: it back in the early eighteen hundreds, which is surprising. Yeah,
Speaker 1: but I mean, like that's the basis of like snake
Speaker 1: oil and hucksterism, right, Yeah, Well they called him bread
Speaker 1: pills back then because I guess it was it was
Speaker 1: probably some sort of like pill made of yeast, as
Speaker 1: my us UH and Thomas Jefferson in eighteen o seven
Speaker 1: even Uh recorded what he called the Pious Fraud, and
Speaker 1: he observed quote that one of the most successful positions
Speaker 1: I've ever known has assured me that he used more
Speaker 1: bread pills, drops of colored water, and powders of hickory
Speaker 1: ash than all other medicines put together. UM, and people
Speaker 1: treated people with bread pills. In the early eighteen hundreds,
Speaker 1: it was a thing and like they were way onto
Speaker 1: the placebo effect and and the fact that it seemed
Speaker 1: to work. Uh. And another dude named John Haygarth in
Speaker 1: the early eighteen hundreds actually started performing the first studies
Speaker 1: on placebo effect, and um, he said it went back
Speaker 1: to the renaissance idea that imagination was the major mediator
Speaker 1: between body and mind, which is starting to be proven
Speaker 1: is possibly correct. Yeah, it's pretty interesting. And in the
Speaker 1: nineties is when they started publishing papers on the placebo
Speaker 1: uh and actually doing clinical trials and um. They said.
Speaker 1: One of their points in the nineteen thirties would confidence
Speaker 1: aroused in a treatment, the encouragement afforded by a new procedure,
Speaker 1: even like just people getting treated in a new way.
Speaker 1: People would say, oh, well, this is gonna work, and
Speaker 1: it maybe he did work. And then we're up to
Speaker 1: the forties where Beacher comes along notices the placebo effect
Speaker 1: himself ultimately comes up with the double blind placebo based study.
Speaker 1: And what's ironic about that is the placebo based double
Speaker 1: blind study ultimately has split back off into the study
Speaker 1: of placebo again because there are so many trials where
Speaker 1: the placebo was more effective than the drug, even though
Speaker 1: the drug worked, but the placebo worked even better. And
Speaker 1: finally in the nine nineties, people were like, what is
Speaker 1: going on here? We need to study this thing in
Speaker 1: and of itself. Well, yeah, because one of the things
Speaker 1: I had no idea. I thought placebos were only used
Speaker 1: in studies for efficacy rates. I did not know that
Speaker 1: they are. There are doctors, always have been, and still
Speaker 1: are prescribing placebos as medicine unknowingly even though they're not
Speaker 1: supposed to. We'll get to that later. No knowingly, no
Speaker 1: unknowingly for the patient, even though they're supposed to tell
Speaker 1: the patient. Yeah, but we'll get to that towards the end.
Speaker 1: But I had no idea that they were prescribing placebos
Speaker 1: to people. Yeah, And in their defense, a lot of
Speaker 1: times doctors are carrying on a tradition where they don't
Speaker 1: have anything else to prescribe. But they can't say if
Speaker 1: they say that to their patients, the patients are going
Speaker 1: to go off and suffer. So at the very least
Speaker 1: they can use the last ditch attempt of saying psychological traitor. Yeah. Yeah,
Speaker 1: and I'm not knocking it. I just was surprised to
Speaker 1: learn that that still happens. And I'm wondering if I've
Speaker 1: ever been given a placebo. And it makes me feel
Speaker 1: dumb as a patient to say, like, yeah, man, that
Speaker 1: whatever you give me really helped. And the doctors like
Speaker 1: because it's the same thing as that prank of like
Speaker 1: giving somebody non alcoholic beer un telling the real beer
Speaker 1: and watching them make a jerk out of themselves getting
Speaker 1: or wrong. It's exactly the same thing. So let's talk
Speaker 1: about placebo. We assume that everybody knows what placebo is,
Speaker 1: but let's define it a little more clearly. The placebo effect, specifically,
Speaker 1: is the very real phenomenon that people, when given a
Speaker 1: pill or a some sort of medical intervention that feel better. Yes,
Speaker 1: they feel better, even though what they've been given is
Speaker 1: not medicine and it was not actually a real intervention. Yeah,
Speaker 1: And the placebo is the pill itself. That that is
Speaker 1: the placebo, and the effect is what you just described, right,
Speaker 1: And it doesn't have to be a pill, can be
Speaker 1: an injection, it can be fake surgery, there's true. And
Speaker 1: it doesn't even have to be uh pharmacologically inert. It
Speaker 1: can be a vitamin or like an aspirin, even though
Speaker 1: some argue that's not a true placebo. But um, sometimes
Speaker 1: that's what the doctor will give you and call it,
Speaker 1: you know, medication, But they're there. Um very often, things
Speaker 1: like a sugar pill. Yeah, like you said, pharmacologically inert
Speaker 1: um and astoundingly, depending on the size of the pill,
Speaker 1: the shape of the pill, the color of the pill,
Speaker 1: people will have different effects and responses to these things
Speaker 1: that are just sugar. Um. So there's some really strange
Speaker 1: psychological things going on here. And at first, for a
Speaker 1: long time, everybody just kind of assumed it was just psychology,
Speaker 1: that we were tricking ourselves into feeling better, or we
Speaker 1: hadn't really felt bad in the first place, and we
Speaker 1: were being tricked into not feeling bad any longer, or
Speaker 1: not thinking we were feeling bad. In any hypochondria, maybe
Speaker 1: very much. So. Yeah, Um, they this article says they've
Speaker 1: been shown to work in about thirty percent of patients,
Speaker 1: and that was actually that's based on Beacher's finding. It
Speaker 1: was like alretty, thirty five point two. Yeah, that's what
Speaker 1: he found out in nineteen fifty five. That's what they're
Speaker 1: still basing that on. Yeah, but there's been other studies
Speaker 1: that have gone back through beat your studies and said no, no, no,
Speaker 1: that's not that much. Other people have found up to
Speaker 1: respond to it, right, And basically one of the big
Speaker 1: questions is is it a psychological effect or are there extual,
Speaker 1: actual physical responses that are going on. And there's been
Speaker 1: a lot of research lately that's pretty interesting. I think,
Speaker 1: like we're saying that the the initial idea was that
Speaker 1: it was all psychological, right, Yeah, Like, uh, well, I
Speaker 1: guess we can talk about the two effects. The subject
Speaker 1: expectancy effect, which is basically, if you know the result
Speaker 1: ahead of time and the pill you're gonna take, you're
Speaker 1: gonna end up feeling that result. Right. That's what a
Speaker 1: blind study seeks to prevent, is a subject expectancy effect,
Speaker 1: and also the observer expectancy effect, which is what a
Speaker 1: double blind studies seeks to prevent. Yeah, and that's important
Speaker 1: because it's are different because it's all self reported, right,
Speaker 1: which is always a little you know, right. So the
Speaker 1: other idea, if it has a psychological basis, is that
Speaker 1: it's classical conditioning that we are raised from birth to
Speaker 1: think that if somebody gives you a pill, you're going
Speaker 1: to respond to it because it has medicine and that
Speaker 1: is not self reported. That is actually seeing physical responses. Right.
Speaker 1: And with classical conditioning established very famously by Pavlov and
Speaker 1: his dogs, right, um, you are you're having You're responding
Speaker 1: physically to a psychological stimulus. Right, So you are getting
Speaker 1: a physiological response. So classical conditioning eventually kind of came
Speaker 1: to be viewed as the more um reasonable explanation for
Speaker 1: what was going on because, uh, study after study, if
Speaker 1: the study has shown that we are having a physical
Speaker 1: reaction to these inert placebos. Yeah, one of them. In
Speaker 1: two thousand two from u C. L As Neuropsychiatric Institute,
Speaker 1: they had a couple of groups of patients and a
Speaker 1: lot of the placebo studies are uh for mental conditions. Um,
Speaker 1: not all of them, but a lot of them are
Speaker 1: in um like the clinical trials. Yeah, yeah, exactly. Um.
Speaker 1: So this one was for any depressants and they had
Speaker 1: two groups that got um experimental drugs like real drugs,
Speaker 1: and then the third was given the placebo. Uh. They
Speaker 1: spent a few weeks on these pills and monitored their
Speaker 1: brain activity with the old E G. Wonder machine and well,
Speaker 1: it's not the wonder machine. It's it's a wonder machine,
Speaker 1: not the wonder machine. Uh. And the patients on the
Speaker 1: placebo reported positive effects and showed greater increase of brain
Speaker 1: activity than those who had responded to the drug. You know,
Speaker 1: I remember or that it was, Yeah, totally undermined people's
Speaker 1: faith in antidepressants because it was on the other end
Speaker 1: of like the whole nineties where everybody was on antidepressants,
Speaker 1: and this study came out and was like people were saying, like,
Speaker 1: do these things even work? It was it was kind
Speaker 1: of taken the opposite way. Rather than wow, the placebo
Speaker 1: effect is really something, it was wow and indepressance or fraudulent. Well,
Speaker 1: I wonder what they were trying to It was a
Speaker 1: placebo study though, right, so kind of backfired or did
Speaker 1: they even care? No, I think it very much carry
Speaker 1: because there when compared to place with the whole point
Speaker 1: of a drug trial is to show that this drug
Speaker 1: is more effective than placebo, it's more effective than the imagination,
Speaker 1: and if it's not, then that means that drugs shouldn't
Speaker 1: be brought to market. Even though now the thinking is
Speaker 1: more like m that's not necessarily true. Because we're coming
Speaker 1: to understand the placebo effect can be very powerful, especially
Speaker 1: depending on the individual too. Yeah for sure. Uh. The
Speaker 1: interesting thing about that study is when the E e g.
Speaker 1: Lit up um, the activity was in different parts of
Speaker 1: the brain. Um. I think that the placebo patients said
Speaker 1: the preformal cortex was lighting up, and basically that says
Speaker 1: that the brain isn't being fooled, it's just doing something different. Yeah,
Speaker 1: they responded better to the treatment then the people who
Speaker 1: responded to the drug. So some people did respond to
Speaker 1: the drug, but different parts of their brain were activated
Speaker 1: by the drug than the people who responded well to
Speaker 1: the placebo, even though they felt better. Yeah, that's mind boggling.
Speaker 1: It is. So they had they reached the same conclusion,
Speaker 1: but using a totally different region of their brain and
Speaker 1: they actually felt better. Um. That wasn't the first study
Speaker 1: to prove that there is a physiological response to placebos
Speaker 1: or last there's a dental study from the seventies that
Speaker 1: I think was the first that showed that if you
Speaker 1: blocked endorphins, which are nature's pain relievers, you can also
Speaker 1: block the placebo effect. So the people weren't responding to
Speaker 1: the placebo like you would expect them to a pain
Speaker 1: reliever placebo because they weren't able to release their natural
Speaker 1: pain relievers. Yeah, and that's backed up I guess by
Speaker 1: this two thousand four study from the University of Michigan
Speaker 1: uh Go wolverines. They basically demonstrated that it is related
Speaker 1: to endorphins specifically. Uh, So that I guess that backs
Speaker 1: up that study because if you can block them. So
Speaker 1: here's the thing. It's not that study was related to
Speaker 1: endorphins specifically. Other studies have found that it can be
Speaker 1: related to how much a person expresses dopamine specifically. So
Speaker 1: there's like this idea that there's a genetic basis to
Speaker 1: our predisposition to UM placebos. But I think that it's
Speaker 1: depending on the drug or the effect that you're trying
Speaker 1: to induce using the placebo effects. Because think about it.
Speaker 1: If you are somebody who naturally produces more endorphins than
Speaker 1: somebody else, Uh, you're going to naturally produce more endorphins
Speaker 1: when it's UM triggered by a placebo than somebody who
Speaker 1: doesn't produce more endorphins naturally. Yeah, So there's a genetic
Speaker 1: basis to it, I guess, But I think the genetic
Speaker 1: basis is that the individual must be predisposition to be
Speaker 1: able to have that genetic response UM to the drug
Speaker 1: or the placebo and have that that um that I
Speaker 1: guess response to it. Yeah, And it's like you said,
Speaker 1: it's also personal because they found that it is even
Speaker 1: affected by a person's personal experience with past pills. The
Speaker 1: color of the pill, the shape and size of the
Speaker 1: pill will have a different reaction because the person had
Speaker 1: maybe took another little blue pill for something else. Sure,
Speaker 1: And actually blue pills in in particular, they are known
Speaker 1: to be um to have sedative effects as placebo's. Red
Speaker 1: pills are known to have stimulating and pain relieving effects
Speaker 1: as placebo. That's odd that they made by agraab blue. Yeah,
Speaker 1: like in Heavinaly marketed it as the little blue pill.
Speaker 1: Interesting sedative effect, Yes, I don't think so. So. Chok, Well,
Speaker 1: not that i'd know. Well, we've got more stuff about
Speaker 1: all this coming up. But I don't know what we're
Speaker 1: gonna talk about next. It's a grab bag right now. Yeah,
Speaker 1: but we're gonna come right back after these messages. All right,
Speaker 1: we're back, buddy, And I tell you what we're going
Speaker 1: to talk about. Something that I had never heard of,
Speaker 1: which I think is super interesting, the no sebo effect.
Speaker 1: It is super cool, and that is when well, it's
Speaker 1: there's a couple of things. That is, when you are
Speaker 1: taking a placebo and you experience maybe the effects of
Speaker 1: the pill, which is great, and the side effec of
Speaker 1: that pill that you think might be but you're supposed
Speaker 1: to have, right, you're actually experiencing side effects that aren't
Speaker 1: shouldn't be there, right, and then a sugar bill. They
Speaker 1: noticed this in clinical trials too, because when you're carrying
Speaker 1: out a clinical trial, you have to warn the patients
Speaker 1: this drug may give you these terrible side effects. And
Speaker 1: so they started noticing like people who were who were
Speaker 1: on placebo were still experiencing the side effect like physical
Speaker 1: reactions like hives and itch in things. Right, So there
Speaker 1: is a there's a negative side to placebo as well,
Speaker 1: and no cibo means I shall harm like placebo means
Speaker 1: I shall please yeah um. And they found that this
Speaker 1: is definitely backed up by the idea that it's classical conditioning.
Speaker 1: They found that people who have gone through chemotherapy UH
Speaker 1: can become nauseated when they enter a room that's painted
Speaker 1: the same color as the room where they received chemo before. Yeah,
Speaker 1: that makes sense. Yeah, so there's all sorts of ways
Speaker 1: that the no cebo effect can pop up, but it's
Speaker 1: pretty mind boggling as well. Yeah, and then no sebo
Speaker 1: can doesn't even have to be just with the placebo.
Speaker 1: You can experience side effects that aren't on the list
Speaker 1: of a real drug because of what we were talking about,
Speaker 1: because it looked like another pill you might have had before. Man,
Speaker 1: the brain powerful stuff. So going back to kat Chuk,
Speaker 1: who I'm I'm just kind of a fan of. Yeah,
Speaker 1: I think if you're into like a long form articles,
Speaker 1: which I love, go to Harvard Magazine and search for
Speaker 1: the placebo phenomenon and it's a profile of him and
Speaker 1: his work. It's really interesting stuff. But he was saying
Speaker 1: that kind of in line with the idea that like
Speaker 1: the color of the pill or the shape of the
Speaker 1: pill will have an effect, will either on the no
Speaker 1: sebo or the placebo effect. Um. He was saying that
Speaker 1: it seems like the basis of the placebo effect is
Speaker 1: what's called ritual yea, and ritual is it involves everything
Speaker 1: from like the physician's bedside manner to how expensive the
Speaker 1: patient thinks the pill is to how effective the patient
Speaker 1: thinks the pillars and um. He did a study where
Speaker 1: he carried out what was called schmaltzy um like a
Speaker 1: smalty care to where he was just lavishing attention on
Speaker 1: the patient and telling him how badly he felt that
Speaker 1: they were going through this. But this pill is really
Speaker 1: effective with your condition. And apparently not just this study,
Speaker 1: but other studies show that there's a positive correlation between
Speaker 1: the ritual and response to the placebo effect. So the
Speaker 1: more you think that this drug is expensive, that this
Speaker 1: drug is effective, that this physician cares about you, the
Speaker 1: greater of a placebo response you're going to have. Yeah,
Speaker 1: you know, I have you ever been accused of being
Speaker 1: a hypochondract by anyone? Know, it's got to be very demeaning.
Speaker 1: It is because it happened to me. And yeah, I
Speaker 1: went to the emergency room in New York, as you know,
Speaker 1: when we were up there recently for a trip. I
Speaker 1: went to the e R and uh, it was something
Speaker 1: and it was a result of it was it was
Speaker 1: throwing up in uh nausea from UM I learned from
Speaker 1: anti inflammatory pills I was taking at the time for
Speaker 1: something else I had nothing to do with being sick,
Speaker 1: and they figured that out, but they kept you know
Speaker 1: this guy, I called him Nurse Jackie. He was just
Speaker 1: like Nurse Jackie, except he was a dude. He kept
Speaker 1: coming by and treating me with things and giving me
Speaker 1: the I V. Drip and I was like, dude, I'm
Speaker 1: not feeling better and I'm not a hypochondrac in any way.
Speaker 1: I didn't go to the doctor for like eighteen years straight.
Speaker 1: And uh, I could tell he was looking at me
Speaker 1: like I got one of these guys. Yeah, And I
Speaker 1: was like, no, no, and I could tell. I could
Speaker 1: could sense it. And so he finally gave me this
Speaker 1: thing to drink that um knocked me out, woke up
Speaker 1: like twenty minutes later and felt felt better. I can't remember.
Speaker 1: It was something to gatorade now. It was like three
Speaker 1: different things. It was like a cocktail of stomach pleasing
Speaker 1: things and what's the stuff that like numbs you numb
Speaker 1: my throat and I can't remember light to can I think? Um? Yeah,
Speaker 1: it worked. I woke up and I felt better. I said,
Speaker 1: you know, I don't feel so naxious now, and they
Speaker 1: were checking me out and I reached up and I
Speaker 1: felt behind my ear for some reason, and it felt
Speaker 1: like a golf ball behind my ear and it had
Speaker 1: popped up in the last twenty minutes, and so I
Speaker 1: was literally leaving. I was like, oh, wait a minute,
Speaker 1: I got this thing behind my ear all of a sudden,
Speaker 1: and this guy looked at me like h and he
Speaker 1: called the doctor over and she was like, yeah, it's
Speaker 1: it's very swollen at your limp node. But he wasn't
Speaker 1: there for that, so he came back over. It's like,
Speaker 1: what did she say. I said, well, she said the
Speaker 1: swollen and he said that you're a hypochondriac. And I
Speaker 1: was so mad at nursed Jackie. I was like, dude,
Speaker 1: look at it. It's huge. I'm not making this up.
Speaker 1: And I started defending myself like I never go to
Speaker 1: doctors and I'm not one of those people. And he
Speaker 1: was just he was like, I was just kidding. I
Speaker 1: was just kidding, and I was just kidding. Yeah, but
Speaker 1: it made it totally made me feel like a jerk. Yeah,
Speaker 1: I mean imagine if like you, if that happened to
Speaker 1: you a lot too, I mean, well that means you're
Speaker 1: a hypocontract right. But now it definitely made me felt
Speaker 1: and I know he was kidding, but it made me
Speaker 1: feel really bad, like I'm in there just uh, what's
Speaker 1: what's the syndrome? Is that it? Yeah, we did an
Speaker 1: episode on that too. Yeah. Uh anyway, sorry about that. Yeah, well,
Speaker 1: I'm sorry that that happened to you. I mean, that
Speaker 1: is b S. But you mentioned the I V guarantee
Speaker 1: you that was just sailing, and that's a placebo in itself. No,
Speaker 1: I mean they told me that. I mean they didn't
Speaker 1: say like this is the wonder bag, but there's basically
Speaker 1: I'm no reason to give you sailing solution. Well to
Speaker 1: hydrate me, I guess if i'd been throwing up. Oh yeah, okay,
Speaker 1: but um yeah, I guess you're right though to see
Speaker 1: like something dripping into your arm, like surely that's got
Speaker 1: to be doing something. Yeah. Uh. Well, one interesting thing
Speaker 1: is back to placebo's, there have been studies that have
Speaker 1: shown that, uh, if you don't tell the patient what
Speaker 1: they're supposed to do, that they don't work as well. Yeah.
Speaker 1: They even found that with drugs that they know for
Speaker 1: a fact work, if you don't tell them it won't work. Yeah.
Speaker 1: They did a placebo based trial with a pain killer
Speaker 1: and the pain killer proved more effective than placebo. And
Speaker 1: then they did another trial with the same pain killer,
Speaker 1: didn't tell anybody what it was and it didn't work. Interesting.
Speaker 1: And then conversely, this is the one that gets me
Speaker 1: to study where they so crazy? Where you're going. They
Speaker 1: used an injection that they put into patient's jaws in
Speaker 1: the study, which me to induce pain Like that was
Speaker 1: the point. They were trying to induce pain in somebody's
Speaker 1: jaw using harmless but pain full jaw injections, and they
Speaker 1: would inject sailine into the jaw um to keep the
Speaker 1: patient's self reported pain level steady throughout the study. And
Speaker 1: then they used another injection and gave them sline but
Speaker 1: told them this was a pain reliever, and everybody's pain
Speaker 1: across the board dropped as a result in the study.
Speaker 1: Unbelievable placebo effect. I could just sit around and rattle
Speaker 1: off studies all day. It's pretty interesting. What do you
Speaker 1: think about obacalp Yeah, it seems kids are done. You
Speaker 1: could just call it placebo anyway, I think it's unnecessary. Well,
Speaker 1: obacalp is placebo spelled backwards obviously, and that in two
Speaker 1: thousand eight was I guess sort of invented or not
Speaker 1: invented but coined and packaged by a mother I think
Speaker 1: Australian named jin Boutner. She Australian, I don't know. I
Speaker 1: think so is that an Australian last name? And then
Speaker 1: I don't think there's such a thing. Um, And so
Speaker 1: that's basically Placebo's for kids. It's marketed. You can you
Speaker 1: can buy a bottle of obacalp and it's for when
Speaker 1: your kid isn't feeling good. But um, you but you
Speaker 1: know your kids not sick, that kind of thing, and
Speaker 1: so you give the kid the pill and it makes
Speaker 1: them feel better. And some people have problems with this
Speaker 1: and say you're teaching your child that you get relief
Speaker 1: from pills only when they're you know, I don't necessarily
Speaker 1: need to be taking pills all the time. And proponents say,
Speaker 1: you know what, it's it's the same thing as putting
Speaker 1: a bandage or kissing a boo boo. It's like you said,
Speaker 1: these are dumb little kids. Well, I remember growing up
Speaker 1: with the children's aspirin, the orange aspirin. I'm pretty sure
Speaker 1: those were just sugar pills. You think I had a
Speaker 1: whole bottle of them, and I was fine, but those
Speaker 1: are vitamins. It was children's aspirin. Oh I think they
Speaker 1: were orange flavored. Yeah, I totally remember those. Yeah, I
Speaker 1: think those are probably place I remember the taste, like
Speaker 1: I can still sense that they're good, the whole bottle
Speaker 1: of them once because I was a little fat kid,
Speaker 1: you didn't eat and get sick sugar pills. I have
Speaker 1: I think so, because I even remember I was old
Speaker 1: enough thinking like I probably shouldn't have eaten that whole
Speaker 1: bottle of those things because it's medicine, and watched it
Speaker 1: down with the sky and I was right and that
Speaker 1: was fine. Afterwards, Well, they do have legit baby aspert
Speaker 1: now though, they I'm starting to doubt everything, so starting
Speaker 1: to talk about doubt. There are plenty of criticisms of
Speaker 1: all this, and we'll talk about him right after this.
Speaker 1: So Chuck, I'm a big time into the placebo effect.
Speaker 1: Your big time into the placebo effect. There are people
Speaker 1: who are not that's true. There Uh, it raises plenty
Speaker 1: of skepticism, which again is one of the reasons why
Speaker 1: my hat is off to Ted Katchuk because he has
Speaker 1: responded to the criticism. He's adjusted his methodolog g he's
Speaker 1: doing really good science in the investigation of the placebo effect.
Speaker 1: I like that guy. Still, skeptics say, there are a
Speaker 1: lot of things that you can use to explain away
Speaker 1: the placebo effect. For example, it's possible the person was
Speaker 1: actually a hypochondriac, they weren't actually sick in the first place. Yeah,
Speaker 1: It's possible that some people get better with no treatment.
Speaker 1: It's possible that some diseases do treat themselves, just get
Speaker 1: better over the course of time. And if if you
Speaker 1: overlay a placebo effect or a placebo and and you
Speaker 1: put that over the same course of time, it's gonna
Speaker 1: look like it was the placebo that did it, when
Speaker 1: really it's just heal itself. Yeah, which is why they
Speaker 1: critics call for studies where there is one UH group
Speaker 1: that has not given any medication whatsoever exactly, which makes sense.
Speaker 1: So UM. One of the other criticisms, though, is that
Speaker 1: if a doctor is is saying and there are, like
Speaker 1: you said, plenty of doctors who do this, UM. There
Speaker 1: there were studies that found that UM. A two thousand
Speaker 1: seven study from the University of Chicago found doctors surveyed
Speaker 1: in the Chicago area had prescribed placebos before at some
Speaker 1: point during their career. In two thousand and eight, they
Speaker 1: did a little more robust when six hundred doctors all
Speaker 1: across the US and half of them said that they
Speaker 1: had prescribed placebos. So this is like, this is still
Speaker 1: going on the thing. It's pretty widespread, and the criticism
Speaker 1: is well, that means doctors are lying to their patients.
Speaker 1: They're using deception to practice medicine, and that's unethical. So
Speaker 1: the A m A came out with it's a guideline
Speaker 1: that's kind of flies in the face of the placebo
Speaker 1: effector of the idea that if you give somebody a
Speaker 1: placebo and tell them it's a placebo, that it shouldn't work,
Speaker 1: which is not necessarily true. Yeah, in two thousand six,
Speaker 1: the AMY came out and said, uh, quote, physicians may
Speaker 1: use placebos for diagnosis or treatment only if they patient
Speaker 1: is informed and agrees to it. To me, that means
Speaker 1: it's not a placebo. I mean I guess it is,
Speaker 1: but if you know it is, I don't get it. Like,
Speaker 1: what's the point of a doctor coming in and saying,
Speaker 1: I'm going to give you the sugar pill? Would would
Speaker 1: you like a prescription for sugar pills, and you say, yes,
Speaker 1: I would. Supposedly, there are um studies that show the
Speaker 1: placebo effect is still works sometimes, but the across the board,
Speaker 1: pretty much everyone believes that if the placebo effect is
Speaker 1: a real thing, the cats out of the bag. It
Speaker 1: is part of the imagination, and that you do kind
Speaker 1: of have to fool the person into thinking that it's
Speaker 1: a real thing. That expectation coupled with imagination provides the
Speaker 1: placebo effect. Yeah, and this article points out to we're
Speaker 1: not just saying these doctors are lying liars um. Apparently,
Speaker 1: one one tech that a doctor can take is to say, uh,
Speaker 1: I have something that I think can help, but I
Speaker 1: don't know exactly know what the deal is with it
Speaker 1: or how it works, but i'll give it to you
Speaker 1: if you want to try it. And you know how
Speaker 1: people are a lot of people are like, sure, I'll
Speaker 1: try anything. Right Exactly, that's not really deception because if
Speaker 1: the doctors are prescribing a placebo he or she obviously
Speaker 1: does believe in the placebo effects, so here she does
Speaker 1: think it could work but doesn't know how, or if
Speaker 1: it only really does work in of the population, then
Speaker 1: you've got a seventy chance of striking out anyway with
Speaker 1: this course of treatment. Uh so you're back to where
Speaker 1: he started to begin with. Yeah, and again it's got
Speaker 1: that falls into what's the point category? Now again, we
Speaker 1: should say that a lot of physicians who do prescribe
Speaker 1: placebos aren't just doing it to toy with their patients.
Speaker 1: They're doing because they think that their patient will suffer
Speaker 1: more without it, or they just don't have anything that
Speaker 1: could be used to address the patient's problem, like they
Speaker 1: can't find anything medically wrong with the patient, but just
Speaker 1: saying that the patient's not going to help. So here's
Speaker 1: a sugar pill. UM. The other tech that a doctor
Speaker 1: can take to chuck is um to say, hey, new patient,
Speaker 1: welcome to my practice. Let me tell you about the
Speaker 1: placebo effect. And in the course of me treating you,
Speaker 1: sometime during your lifetime, I may find that a placebo
Speaker 1: will be the best thing to use. Are you okay
Speaker 1: with me doing that to you at some point possibly
Speaker 1: basically like signing up for my own personal U long
Speaker 1: term study kind of as a doctor. But wouldn't you
Speaker 1: from that point on be like you just gave me
Speaker 1: the placeboy, it's a placebo. I know it's a placebo.
Speaker 1: I wouldn't know which way was up, Like, I don't
Speaker 1: know how to feel. That's the better worse side effects? None, yep.
Speaker 1: And the other tech doctors can take is to knock
Speaker 1: off early and go hit the golf course, which they
Speaker 1: do that one a lot on TV. That's a that's
Speaker 1: a that's such an old bit trope. It's like, yeah,
Speaker 1: cops in their doughnuts? Is that doctors in golf? I
Speaker 1: think that was pretty accurate. I mean in Caddyshack, the
Speaker 1: doctor was Dr Beeper. He was the one who just
Speaker 1: got mad all the time, right now. That was Judge Smailes.
Speaker 1: Dr Beeper was he was just one of the guys,
Speaker 1: one of the foursome, okay that I think he played.
Speaker 1: Was it Buck Henry? Was he the doctor? No? I can't,
Speaker 1: I can. I can picture the guy. It's Buck Henry, right,
Speaker 1: I don't think so we'll figure this out offline. How
Speaker 1: about that? Yeah? All right? If you want to know
Speaker 1: more about the placebo effect, and believe us there is
Speaker 1: plenty more to know about it, you can type those
Speaker 1: two words in the search part how stuff works dot
Speaker 1: com and uh, since I said that, it's time for
Speaker 1: a listener mail. I'm gonna call this Australian last name.
Speaker 1: This is, he says, dear Josh, Chuck and Jerry and
Speaker 1: anyone else I should think, And I think we never
Speaker 1: mentioned other people that support us. Didn't we already talk
Speaker 1: about in Australian last name? Yeah, that was the joke. Okay,
Speaker 1: let's call the call back, gotcha. I just felt like
Speaker 1: this listener mail, though, made me realize that we don't
Speaker 1: think other folks a lot besides Jerry and like Noelan Matt.
Speaker 1: But um, let's do that noway. Like Rebecca h Rebecca
Speaker 1: is uh, what's her official title? I don't even know
Speaker 1: what titles are around producer web producer maybe yeah, I
Speaker 1: mean she handles our website. It makes everything look great.
Speaker 1: And Sherry, even though we do our own social media,
Speaker 1: Sherry does social media for how stuff works. And she
Speaker 1: throws to us a lot, throws to us and helps
Speaker 1: us out a lot. And Joe, our buddy, Joe is
Speaker 1: a huge help um, and that's kind of the crack staff.
Speaker 1: I mean, we're answering our own emails and we're doing
Speaker 1: a lot of our own stuff, but it doesn't mean
Speaker 1: we don't have help. You know what I'm saying. We
Speaker 1: have tons of help, so you know, I just want
Speaker 1: to say thanks to this. It's very nice if you
Speaker 1: chuck thanks everybody. I figured six years and seven years
Speaker 1: and we might as well shout out some of our help.
Speaker 1: Uh So this from Alex and he said to thank
Speaker 1: anyone else he doesn't know about. And he's from Perth,
Speaker 1: Western Australia, which is nothing like Eastern Australia. I'm a
Speaker 1: nineteen year old aspiring electrician trapped in the depths of
Speaker 1: Western Australia's mining downturn due to layoffs in the mining sector.
