=== Debunking the Mozart Effect (06:00) ===

[00:00:03]  It's one of those things that we've all heard and that many of us take for granted.
[00:00:06]  Play music for an unborn baby, specifically Mozart, and it will help their brain develop faster and smarter and confer extra abilities like spatial intelligence.
[00:00:18]  Today we're going to put this very popular belief to the test and also answer some other questions sent in by students.
[00:00:26]  Student questions are coming up next on Skeptoid.
[00:00:33]  Hi, I'm Alex Goldman.
[00:00:35]  You may know me as the host of Reply All, but I'm done with that.
[00:00:39]  I'm doing something else now.
[00:00:41]  I've started a new podcast called Hyperfixed.
[00:00:44]  On every episode of Hyperfixed, listeners write in with their problems and I try to solve them.
[00:00:48]  Some massive and life-altering and some so minuscule it'll boggle your mind.
[00:00:53]  No matter the problem, no matter the size, I'm here for you.
[00:00:56]  That's Hyperfixed, the new podcast from Radiotopia.
[00:00:59]  Find it wherever you listen to podcasts or at hyperfixpod.com.
[00:01:09]  You're listening to Skeptoid.
[00:01:11]  I'm Brian Dunning from Skeptoid.com.
[00:01:14]  Student Questions, the Mozart Effect, Quantum Theory, and AIDS.
[00:01:20]  Once again, a giant round of thanks to the students who have sent in this week's questions.
[00:01:25]  If you're a student and are wondering about some pseudoscience or other skeptical question you've heard, send it in and I'll answer it in a future episode.
[00:01:32]  Just come to skeptoid.com and click on Answering Student Questions.
[00:01:38]  Let's get started today with Jerome from the Philippines.
[00:01:42]  Hey, Brian, this is Jerome Clemente from Manila Philippines.
[00:01:45]  I want to hear your take on the Mozart effect.
[00:01:48]  Can music really affect the intelligence of an individual?
[00:01:51]  Like they say that rock music can make you dumber and classical music can make you more intelligent.
[00:01:58]  Like me, I listen to have a middle, but I don't feel stupid.
[00:02:01]  Thank you.
[00:02:02]  I'm glad you asked.
[00:02:03]  It just so happens that my wife, Lisa, was one of the test administrators when this research was originally conducted in the early 1990s at UC Irvine by Dr. Gordon Shaw, a physicist, and Dr. Francis Rauscher, an experimental psychologist.
[00:02:18]  The idea was to test whether young children's spatial temporal IQ scores could be improved by listening to various types of music.
[00:02:27]  Although they had some promising preliminary results from a particular Mozart piece, which made immediate worldwide headlines, the full study eventually showed no significant result.
[00:02:38]  I once spent half an hour with Gordon Shaw in his office, batting a crumpled-up ball of paper back and forth and discussing his theories on dark matter.
[00:02:47]  I asked him straight out what the research showed so far, and he said something like, basically bupkiss.
[00:02:53]  Even though strictly speaking, that violated the blinding on a couple of levels, but I think by then they were just about done with it and had zilch.
[00:03:01]  Nevertheless, as you probably know, the headline, Mozart Makes You Smarter, was such a great one that whole industries exist around it, more than 15 years after it was conclusively falsified.
[00:03:15]  Selling Mozart CDs to pregnant mothers and claims that music therapy cures all sorts of diseases and everything else a snake oil salesman can invent.
[00:03:25]  In short, the testing found the claim to be pure pseudoscience.
[00:03:29]  The most significant effect of buying a Mozart CD in hopes of making your child smarter is to transfer a sum of money from your pocket into that of a company exploiting sensationalism.
[00:03:41]  Hello, my name is John and I go to Westchester Community College in New York.
[00:03:46]  I often hear the terms quantum physics and quantum theory used by people pushing pseudoscience.
[00:03:51]  Can you give me a brief introduction to what quantum is and why it is so useful to bad science?
[00:03:56]  Thanks.
[00:03:57]  This is a great question.
[00:03:59]  It is so tiring to hear peddlers of supernatural nonsense supporting their claims by citing quantum physics.
[00:04:07]  The word quantum refers to the smallest discrete unit possible.
[00:04:11]  For example, a quantum of light is a photon.
[00:04:15]  You can't have half a photon of light.
[00:04:18]  Max Planck discovered around 1900 that energy is always transmitted and absorbed in discrete units, which are called quanta.
[00:04:28]  Quantum theory is the study of matter and physics at a very small subatomic scale.
[00:04:33]  Classical physics deals with a large-scale world, where I drop a rock and it lands on my foot, or a planet orbits the sun and is held in place by gravity.
[00:04:42]  In the quantum world, these physics no longer apply, in part because that world is driven by different fundamental forces, and we have weird things like particle-wave duality, and singularities, and spin, and entanglement, for which there are no analogs in classical physics.
[00:05:01]  Our brains evolved in a different world, so it's really hard for us to wrap our heads around quantum theory.
[00:05:08]  Thus, it's the perfect reference to support a meaningless pseudoscience.
[00:05:12]  Nobody understands it.
[00:05:14]  Nobody's qualified to falsify its relevance to the claim.
[00:05:18]  Everybody's impressed by the term.
[00:05:21]  When Rhonda Byrne wrote The Secret and claimed that quantum physics explains how you can wish for things and they'll magically appear, she didn't know anything more about quantum physics than the average person on the street.
[00:05:33]  She's just a smart enough marketer to know that when people hear the term, they're impressed.
[00:05:38]  Ask a theoretical physicist who has read her chapter on quantum theory.
[00:05:42]  Not a single word of it makes any sense.
[00:05:45]  It's just childish techno-babble to impress the masses.
[00:05:49]  Real quantum theory has no conceivable relevance to paranormal claims like the secret or what the bleep do we know.
[00:05:57]  Thus, its frequent employ is almost always without any scientific meaning.

=== The Alkaline Diet Myth (02:09) ===

[00:06:03]  Hi, I'm Bailey from William Smith College, and I'd like to know if there is legitimate science behind using an alkaline diet to treat GERD.
[00:06:11]  GERD, basically gastric reflux disease, is a chronic condition where stomach acids come up into your esophagus, causing heartburn discomfort and also tissue damage.
[00:06:22]  When this happens a lot, your esophageal sphincter can be damaged, which makes the situation even worse.
[00:06:29]  An effective symptomatic treatment is to take an antacid, like TUMS, which quickly neutralizes the acids in the esophagus and eases the discomfort.
[00:06:38]  Effective long-term treatments include drugs that block acid production, changes to your sleeping position like elevating the head, and weight loss.
[00:06:48]  What doesn't work so well is making your diet more alkaline, i.e. less acidic.
[00:06:54]  According to a number of studies, eating less acidic foods and even consuming antacids stimulates additional acid production in the stomach to digest it.
[00:07:04]  Now, that's okay, your stomach is designed to hold highly acidic contents, but it means your reflux is probably going to continue.
[00:07:12]  Most research does not support an alkaline diet to treat GERD.
[00:07:18]  Your best bet is to eat a lower calorie diet to help you lose weight, watch your sleeping position, treat the symptoms with antacids only as needed, and if it continues, consider drugs to reduce acid production and give your esophageal sphincter a chance to heal.
[00:07:38]  Hey everyone, I want to remind you about a truly unique and once-in-a-lifetime adventure.
[00:07:45]  Join me and Mediterranean archaeologist Dr. Flint Dibble for a skeptoid sailing adventure through the Mediterranean Sea aboard the SV Royal Clipper, the world's largest full-rigged sailing ship.
[00:07:58]  This is also the only opportunity you'll have to hear Flint and I talk about our experiences when we both went on Joe Rogan to represent the causes of science and reality against whatever it is that you get when you're thrown into that lion pit.

=== Mediterranean Skeptoid Adventure (05:11) ===

[00:08:12]  We set sail from Málaga, Spain on April 18th, 2026 and finish the adventure in Nice, France on April 25th.
[00:08:21]  You'll enjoy a fascinating skeptical mini-conference at sea.
[00:08:26]  You'll visit amazing ports along the Spanish and French coasts and Flint will be our exclusive onboard expert sharing the real archaeology and history about every stop.
[00:08:36]  We've got special side quests and extra skeptical content planned at each port.
[00:08:42]  This is a true sailing ship.
[00:08:44]  You can climb the rat lines to the crow's nest, handle the sails.
[00:08:47]  You can even take the helm and steer.
[00:08:50]  This is a real bucket list adventure you don't want to miss.
[00:08:53]  But cabins are selling fast and this ship does always sell out.
[00:08:58]  Act now or you'll miss this once-in-a-lifetime opportunity.
[00:09:01]  Get the full details and book your cabin at skeptoid.com slash adventures.
[00:09:08]  Hope to see you on board.

[00:09:19]  Hello, Brian.
[00:09:20]  I am Javier from FSU at Tallahassee, Florida.
[00:09:23]  I read online that there is no scientific evidence showing the relationship between HIV and AIDS.
[00:09:29]  I would like to know what do you think about this and the HIV conspiracy theory?
[00:09:33]  Thanks.
[00:09:35]  First of all, it's important to understand that the fact that AIDS is caused by the HIV virus is thoroughly established and is beyond any reasonable medical question.
[00:09:45]  The best article I've seen that explains how we know this is by the U.S. Department of Health and Human Services and is reprinted on Dr. Stephen Barrett's excellent QuackWatch website.
[00:09:57]  The article also goes through many of the specific claims made by the people who doubt the relationship and explains the facts behind each question.
[00:10:06]  The medical questions are raised and answered, and also a few of the crazy conspiracy questions are outlined.
[00:10:12]  For example, AZT and other anti-retroviral drugs, not HIV, cause AIDS.
[00:10:20]  You know, the whole thing where American big pharma conspires to spread death and disease throughout the world in order to maximize profits.
[00:10:27]  Well, that's goofy, of course, but you can banter the goofiness back and forth all day long.
[00:10:33]  Whereas this article describes clinical trials that have proven AIDS is not caused by AZT or any other drugs.
[00:10:40]  The scientific evidence showing that HIV causes AIDS is vast.
[00:10:44]  There's a link to the article titled The Evidence That HIV Causes AIDS in the online transcript for this episode.
[00:10:53]  Hi, Brian.
[00:10:53]  This is Kevin Dennerman from Toronto, Ontario, Canada.
[00:10:56]  And my question is, is recycling really environmentally or economically friendly?
[00:11:03]  Exceptions abound, but generally the answer is yes.
[00:11:06]  Recycling does often have limited environmental benefits.
[00:11:10]  And no, recycling rarely makes economic sense.
[00:11:14]  Here's an oversimplified example.
[00:11:16]  Let's say you're a manufacturer who buys aluminum.
[00:11:19]  You can buy it from the mining company who finds it profitable to employ miners to dig it out of the ground, refine it, and sell it to you.
[00:11:27]  Or you can buy it from the recycler at a similar price.
[00:11:31]  Is it profitable for the recycler to employ drivers to go around collecting recycle bins and selling it to your factory?
[00:11:38]  No, which is why they don't pay the owners of those bins the way the mining company pays its miners.
[00:11:43]  The recycling company has to charge the owners of those bins.
[00:11:48]  That's why all of our monthly utility bills cost extra to have a recycling bin collected.
[00:11:54]  Aluminum is also a great example because it's the most recyclable of materials.
[00:11:59]  It can be recycled over and over again forever and is the only recyclable material that pays for itself.
[00:12:06]  Nevertheless, it takes only 5% as much energy to make an aluminum can from natural ore than it does to make a recycled can.
[00:12:15]  Manufacturing from raw materials enjoys an economy of scale, unmatched by the tedious inefficiency of driving trucks around to everyone's house, hand-sorting every piece of garbage, and driving more trucks around.
[00:12:29]  Paper is among the worst materials to recycle, making neither economic nor environmental sense.
[00:12:36]  Paper manufacturers plant trees, which are a renewable resource, and they suck carbon dioxide out of the air.
[00:12:44]  Paper recyclers drive trucks around, hand sort, and drive more trucks, emitting carbon dioxide into the air.
[00:12:53]  But it's not a simple question.
[00:12:55]  What do we do with our trash when we're done with it?
[00:12:57]  Bury it in a landfill or pay the costs of recycling?
[00:13:01]  Neither solution is desirable.
[00:13:03]  The important lesson to learn here is that improvement is needed throughout the process.
[00:13:08]  And all existing solutions have downsides crying out to be addressed.
[00:13:14]  So don't oversimplify it and conclude that recycling is either good or bad.
