I love how humble that man was, didn’t want to say he’s an expert after a mere 55 years of study. Contrary to the guy selling the salt lamp, he had all the answers with zero knowledge.
Good point on the comparison. I started college after 10th grade a "know it all", but now I often say that the most important thing that I learned at MIT was to say "I don't know". I learned it by seeing other experts speak like the one in this video. Once I can admit that what I know is a drop in an ocean of knowledge, it allows me to see that this ocean exists and gives me freedom to begin to explore it.
@@MrStanaland that’s an excellent point. I definitely won’t start at MIT after Sophomore year, but that is definitely something I need to remember. Thank you
It was also refreshing how Veritasium interacted with the salt lamp seller, Derek wasn't confrontational or arrogant. He wasn't trying to prove the seller wrong or make the seller feel guilty, because he knows that the seller guy just has the wrong info, and that's why he made this video, to give the right info to the people who need it. This is the type of education I like to see, one that doesn't talk down to the uneducated.
8:51 "So, your conclusion is that it's not producing any negative ions?" "We certainly aren't able to detect any ions." I love his response. It's such a humble, carefully worded, and scientific response. He doesn't say definitively that the salt lamp is not producing ions, just that they simply are not detecting any ions from the salt lamp. It is a subtle but important distinction, and a great example of how easy it is to develop hubris from literally anything if you're not paying attention to yourself. The scientific community - no, the _world_ needs more of this.
Alternative perspective is rigor. Rigor and humility may be associated but in this case I tend to focus on the rigor more. I personally practice rigor a lot, on a daily basis, and in casual conversations, rigor may not always be desired. In communication, it seems we oftentimes face a tradeoff between the accuracy of the statements and the cognitive load on the humans.
@@xj-vn4eo I don't think I've heard (or read) the word 'rigor' in the context that you're using it. What do you mean when you say you practice rigor a lot?
Adam Neely (A music channel) also does this, asks a question in the title, and promptly answers it in the thumbnail and honestly, Its refreshing to see that from educational channels
I adore how when Derek asks "are you an ion expert" the answer isn't yes or no. It's "here is my level of experience in the field." which gives you a way better idea of why you should listen than just "yes i am"
@@Demmrir The idea is that someone who studies something for 3 hours a day for 10 years, will have an expert-level of knowledge in that subject. The word “expert” is quite subjective. I feel like an expert is someone who devotes their entire life to that thing. There’s not some magic number you have to achieve and all of a sudden you’re an “Expert”. It’s just an estimate.
when i saw the title, i had no idea salt lamps were supposed to be anything other than aesthetic lamps, so I was like of course they work. They produce light and look nice.
For some reason I thought they were meant to remove moisture in the air? I don't know why I assumed that. I never knew anything about the ions until this video.
The thing with the thunderstorms, oceans and beaches is that they are already quite exciting on their own - so it's normal to feel different/better when experiencing them.
I was wondering how the effect would compare if you put a small fountain of water in your home or office, or even a recording of waterfalls or ocean waves. Also if the ionized air is creating a breeze, has that been tested against a gentle fan for creating the impression of fresh air?
Never thought salt lamps did anything besides give off a present soft pink/yellow light that's perfect for a bedside stand. I like them for aesthetics and practicality.
It's a big glowing rock that's perfect for people with light sensitivity (like me). I'd love to get one, but I'm sure my cats would knock it over immediately- mostly out of spite.
Being strict with conclusions is what makes good profs so boring when you're young but you gotta appreciate how responsible they with their language when you grow up
He did imply placebo. The moment he brought up people feeling happier, I was very curious whether the test was blind. Glad that was the point he was working towards.
@@ToonedMinecraft I didn't hear the participants were told to pay attention if they got happier during the experiment. So, they didn't know this could be one of the reactions. In short, academics will only accept ions have a positive effect on humans only if they get an affidavit, signed by the ions themselves, that they influence in a positive way health and mood of humans.
@@CyberSway Yeah. And worse. Much investigations have been done, during the XIX and beginnings of the XX century, where one discovery was that humans cells can emit and receive EM waves. And we got this guy here asking himself if ions have an influence on the human body and mind. And because he knows, the answer must be "No", he overlooks even positive results confirming that ions have that influence.
I just love how the scientist are so open-ended with their responses. None of them said absolutely not to any experiment. They all said stuff like " i believe or, or it appears to be that way".
hat's the point of science! If you ever hear anyone say something along the lines of "I absolutely know," they're either lying or trying to sell you something.
@@erich930Typically I would use something more along the lines of "The evidence resulting from this experiment supports the claim/argument that...," rather than a statement of personal belief in the claim.
Many scientists do this as a faux humility though. Then under the pressure of the pandemic most of them went crazy for masks and vaccine mandates at Caltech, which was the opposite of being humble or scientific.
@@commscan314 It's unfortunate that doesn't work in day-to-day conversations with, say, your parents, friends or family. People that aren't scientific minded get bored, or don't internalize it if you say it that way. See Veritasium's video about anecdotes vs data (idk the current title, but if you look for "anecdotes veritasium" you'll find it) A compromise I like to use is to reply with "yes, most likely" or "it does seem that way" then add an anecdote. Normal people take that more seriously this way.
That's literally how science works, genius. I know your democrat friends taught you the concept of "The Science is Settled", but no scientific theory is ever "settled". This language is not only normal, it's how it's supposed to be.
I was ready sending this to a friend who is a bit into those fancy fantasy toys. He knows their claims are bs but he also knows if he believe they work, he will have the desired affect. I don't know what to do now ,
I think the way the video is presented does a fantastic job of showing how impressionable we are. If a viewer paused at various points and walked away they would leave with a totally different viewpoint because we don't tend to continue with our own research, instead trusting the presenter to be honest (or at least not motivated by funding or advertisers).
I have never believed that salt lamps have any benefit for the health, chemically speaking. However, I do believe that their warm, pinkish, orangish glow is good for mood. And they look very cool.
The package of the salt lamp I bought wrote, it has a calming effect. I like the soft, warm light. I like to think that these lamps do help to calm down. I set the lamp near my bird cage. I have canaries and they often wake up during the night or are awake for too long. Every time I turn on the lamp they sleep better.
salt is the ingredient. People use salt inhalers to improve airways. People pay to travel to get therapy in salt caves. And if these are run for some time they do shed the salt around the lamp so I always put my salt lamp on a saucer or plate.
“Are you an ion expert?” “I’ve been studying ions for 55 years.” I love it. He’s not saying he’s an expert, he’s giving you information and letting you decide.
I like when people make thumbnails like this. It answers the question and makes you go like: well why doesn’t it work? And then you have to watch the video to find out why. This is a much better strategy than click bait
tbh it takes a lot of effort to debunk without hurting feelings, but it's a good way of doing it as the gullible person is less likely to dig their heels in and double down on their pseudoscience nonsense. Wish I had the patience to explain stuff as well as Derek.
honestly it wasn't debunked hard enough. i'd bet someone who already thought this effect to be real would come out of this video thinking "oh so the tests that weren't done didn't _yet_ show the real effects, they'll need to test it harder to prove i'm right"
I like to think that when he's walking with the camera he's actually grabbing us by the throat a dragging us along while rambling about ions and salt lamps
@@OmnistrikeRZ probably forgot the chant as well. Should've also protected the nozzle with a thin sheet of silk to keep interfering dark forces out, those eat ions. Amateurs.
@Benjamin gammer The interesting part was that he got all the scientists to pretend like it was an actual thing to investigate, and not the patent nonsense it really is.
They do work. I’ve eaten about 15 of them by now and I feel great! A little dehydrated and I now have high blood pressure but that’s easily fixable, I’m sure.
I think another important thing to point out about the ion "tests" is that doing these tests in things like office settings is a great way, experimentally-speaking, to get a positive result without knowing if you've identified the correct cause. Sure, people probably do notice an improvement in mood and general behavior when an ionizing air purifier is put into the room, but that doesn't just change the ion content of the room. I could very easily imagine introducing an air purifier to an office that previously didn't have one would improve air quality *in general* and improve air flow in a room that's probably rather stuffy otherwise. Sure, it could be the ions... but it could also be a lot of other things.
@@simoringenfreitag5603 Yeah but what if the air purifier produced a sweet smell like the one tested in this video? That would also obviously impact productivity. The point was a lot of the studies, including that one, were poor quality. That doesn't make them useless, but it does mean the only real conclusion you can draw from them is "it would be good to repeat this study but do some things differently".
My salt lamp works perfectly...It lights a hall at night so I don't trip over something and break my leg. Works perfectly at keeping my legs healthy. :-)
You have to give things the benefit of the doubt. Be sceptical all you want, but you need to allow things the opportunity. We cannot have science, if we do not test things.
@@kolelokaram8541 Without the "but". Being skeptical includes being skeptical of the things you know, and basing your assertions on that which has more evidence. Be skeptical that negative ions AREN'T good for you, gather some evidence and conclude. You might discover something along the way
I also love how the professor spoke like a true scientist: Veritasium: "It's producing no negative ions" Dr. Dalleska: "We're certainly not able to detect any negative ions" There is always that very very small chance that it is indeed producing, but we're not able to detect it. So as a scientist you can't say with absolute certainty that it is not producing.
My entire life I got bad grades in school. Geography was the exception because of the passion I had for Nature... So it was easy to learn something I intuitively understood. But... YOU have made learning any subject a want to do, not a have to do... I am so grateful for the scientific learning you provide on Veritasium! I wish people like you ran schools across the planet. We wouldn't be in this divided world if education was performed correctly... Thank You!
i really like how you portray the narrative around this subject. You start off by explaining all the reasons why negative ions are good for us, show us a giant stack of papers written about the subject, and give an example of a study showing positive results. Only to come in at the end and show how despite all that, the claim is not proven at all. This is a good representation of how we should never believe something just because it seems to be true.
Also, just because a paper (or many papers) is written supporting something, doesn't mean it's true. The quality of the evidence makes a big difference.
8:50 Veritasium: So your conclusion is (..) that it produces no negative ions? Scientist: We are certainly not able to detect any negative ions. That's a true scientist's answer!
I yelled same thing to the screen. On point answer. No strict conclusions can be drawn through single test with single method on a single sample. But detected evidence as the result of that test can be spoken for.
Love this! I have a whole Himilayan Mountain range of these lamps in my house, but have only ever purchased them for their aesthetic qualities, a.k.a their moody pink and orange glow. Everytime anyone comes over and comments on them, I feel I have to give them the disclaimer that I don't actually believe the new-age-woo associated with them, and that they're just for decorative purposes.
Same, I received one from my mother who genuinely does believe in the pseudoscience, but I have to continually remind her of its falsehood. She is not willing to accept it. In the meantime, I have acquired a wonderful mood-lighting lamp.
since this is veritasium i at least tried to think to myself "why would that even make a difference? this makes absolutely no sense" and was patiently waiting for an actual explanation to change my mind and learn something new. not really surprised to see that it didn't come to pass, but it did have me on edge for a while.
I really like the facts presented in this video, and how they were presented. It also may explain why I like being around waterfalls and beaches, and why I love going outside after a thunderstorm. I also like that professor who doesn't just answer "yes" to being an expert, but rather gives his credentials like any true scientist would and leave it at the listener's discretion to determine expertise (because a real expert would know there's always more to learn). Even more fascinating is that there really IS a crystal that will produce ions when heated, a shame it's too expensive for normal sales purposes.
This video is just one example of how much information and explanation it takes to disprove a statement someone makes in less than 2 seconds. This is why things like "alternative facts" persist: no one has the patience to actually learn things.
I feel like most people don’t know what Alternative facts are. That was just someone saying that “my research contradicts yours” in a very poorly worded way.
Its worse than that though. Its not just about disproving things that aren't true, but its also that its really difficult to go through "peer reviewed literature." Honestly, unless you are at least working on a graduate degree, its probably a waste of time to mess with the incredibly tiny details of peer reviewed research. I know there are problems with news journalists, but generally the best source of looking critically at a claim is simply asking "what is the mechanism by which this assertion works." Quickly you get the explanation about some production of serotonin and then you consider how few negative ions you breathe in relative to all the atoms you breathe in and you quickly see how ridiculous the claim is. You don't need to mess about with research and studies, just use common sense. That's going to get the lay person way further than mucking through details that ought to be left to people who have nothing else better to do.
Notice how when Prof. Beauchamp was asked if he was an "expert," he only provided his credits and never said yes. That's the type of guy that I would trust over someone that upfront refers to themselves as an expert in anything.
The idea of being an "expert in ions" is ridiculous to begin with, its such a broad category, so yeah it'd definitely be concerning if someone claimed to be an "expert in ions"
Scientists answer questions really carefully. Notice when Derek asked the professor, “does that mean the salt lamp doesn’t produce negative ions?”, and he answered, “we didn’t get to detect any.” 😂 many statements that normal people think equivalent could appear not directly but only conditionally so.
I love how the answer to "are you an ion expert?" was "I've been studying ions for...55 years, and have written hundreds of papers on all aspects of ions." He is not claiming to be an expert, he is just stating his experience.
Beware of those who call themselves to be "social scientists" or "social engineers," as they suffer from dyscalculia They are ultra-extreme leftists with multiple personality disorders. They can't reason or think logically.
Sterf Google I am half an expert on phonetics. For decades, I had severe speech impediments, because I had too great a difficulty in distinguishing sound-alike letters in my flawed hearing. Eventually, I bought books on phonetics like those on IPA letters, intonations, voice-training for actors & singers, elocution, etc. I meticulously studied all speech parts, their lip positions and tongue positions. I regularly keep a small notebook on pronunciations of obscure words and jot them down in IPA letters indicating certain sounds. Today, I speak fluently.
Think about how many other people have walked by that lamp, thinking the very same thing... then pulled an Ariana-Grande-not-so-secret-lick in that VERY same spot that YOU just licked👅🤢🤭😉
I thought the opposite, those are his old professors from his Master's program. The comfort level is quite high. The way the one man said, "Hi Derek" I could hear 'what now?' resigned to his constant curiosity.
Salt lamps absolutely work! I received one for Christmas and it definitely emits light. Not only that, but the lampshade that surrounds it prevents any chance that the naked bulb will be visible to me.
@@ericulric223 yes, I grew up on Spock's logic and curiosity, his 'superpowers'. I often spill a drop of ale to Brother Roddenberry for the Utopian vision he created for us to aspire to.
As someone actively doing research in neuroscience, it felt uneasy to hear the salesman confidently saying 'Serotonin is, like, the primary transmitter in your whole body'.
My research has absolutely nothing to do with it, and that alarmed my sham detectors. I would've instantaneously noped out of there. Also the dude just claimed that all living things work like that. That's a *very* bold claim.
Yeah? Well you folks in Big Serotonin WOULD say that, wouldn’t you? Always trying to crowd out artisanal, small-batch serotonin artistes from the marketplace :-(
i suffer from depression and was naturally gravitating toward the beach and outdoor living. after watching your production, i now understand my love of beaches and constant desire to go to the beach. i also have an aversion to artificial air. thank-you for your work.
Finer sand beach has more negative ions. You will get 20x more negative ions in your bathroom on average with warm shower running. Cold air conditioning will generate net/more positive ions.
That salesman basically claimed the lightbulb inside the lamp was hot enough to sublime salt, but still safe to have turned on in close proximity to people.
@@Rig0r_M0rtis sublimation is the phase transformation directly from solid to gas. It is a line on the pressure/temperature phase diagram of a material, so sublimation temperature will depend on the pressure. At some pressures there will be no sublimation because the liquid phase can exist. But as an example, CO2 has a sublimation point at ambient pressure, which is the reason why dry ice exists. But for NaCl at atmospheric pressure it will melt and then boil, so no sublimation.
Great video Derek! Pertinent in an age where people aren't willing to listen to each other and only attempt to persuade , ending up in even more biased and extreme positions. It was also a good example of how cognitive dissonance works both ways. I could feel myself getting frustrated at the first 3 minutes of the video when I believed you to be proposing an "unscientific" concept. Thanks for being a great example of how we can make science more well received by the general public by making it less patronizing. Science shouldn't be polarising.
When you need a click baity title but you are a man on standard and wont allow pseudoscience to influence people who didnt click or watch through the video..
Well I don't know about you guys but I love my salt lamp. I have anxiety and depression and the cozy glow of the lamp brings warmth, comfort, and relaxation to me. 😌 And with that, I say it works for me.
Well, I have three salt lamps, and I've always been skeptical to the whole negative ion thing. I still enjoy them because they are nice to look at, and provide a nice level of low light conducive to my circadian rhythm in the evening. What I especially like about this debunking is that anyone who has these lamps can go forth and spend less money in the long run on both bulbs and electricity by using LED night light bulbs instead, because who cares if it produces less heat. Thanks for the info!
Quick heads up though if you want to use a bulb that puts out less heat you gotta make sure the salt lamp isn't exposed to any kind of humidity. If it's not kept hot enough it tends absorbs moisture and can melt. Messy as all hell to clean up lol
it s so true that learning is not about facts but about stories that seems to bring things to an understanding within my brian . i love I can read and hear and watch all at the same time.
@@spadaacca how generous. But solving a bit of salt in water is enough to make ions. And I guess drinking or breathing this should have exactly the same effect
wouldnt it be better if they were designed to produce positive ions? i think we could all do with being a bit less negative. who wants to go into business with me?
It's kind of reverse psychology. If it didn't say "no" in the title, it would probably get less views because the subject isn't that interesting to many of us, even though we've all heard of these lamps. However, when you bring to mind that no, they don't work... well that's more interesting because I'm asking myself "why doesn't it work"? Which the video is destined to answer. So in conclusion, it's almost more clickbait than it otherwise would be. But there's nothing wrong with clickbait.
there's no such thing as ion expert except for laymen and hippies maybe. so if i was asked about that i would be very, very embarrassed to say yes even if i was, in fact, an ion expert.
Wow! Derek, this is currently my FAVOURITE video you've ever made! Just super enlightening! I had given away our salt lamp years ago. Loved the segment on natural generators of ions!
AntsCanada They still looks nice and cozy, that’s why I have them. But I never believed it has any health benefits, which is now supported by science as well
Hahahaaa Mickey... Your all over my favourite channels mate! I'm coming back to the Philli's soon, so hope to meet you.. Derek... There are OZONE water machines where you drink water with high amounts of ozone and it's supposedly good for GUT HEALTH and was wondering if you could debunk that too, or not>?;)
just learned what salt lamps are and came here to see if the hype is true. I must say I had my doubts but I remained hopeful. ty for clarifying everything.
For many years now Ive been subscribed to your channel & I can honestly say, I always get excited EVERY time I see a notification that you have uploaded a new video. I have learned so much from your channel! I want to thank you for your hard work & for encouraging all us young people to not only pursue physics, but also not to be dismissive of other people's points of view. Youre open minded yet unlike many academics, I have never heard you be dismissive of the fact someone might be religious or spiritual & that they want to be a man of science, (something that two of my professors do all the time). You are the reason I decided to choose to get my undergrad in physics with the hope that when I finish my undergrad here at Carnegie Mellon, I can get my PhD in astrophysics. I still have two more years..... if school isn't tough enough, the fact that I have to work makes it really tough but its so worth it! You were a big part of my decision to pursue physics & by doing so, I found out that the pursuit of knowledge through the world of physics is not simply want I want to do for the rest of my life, its what I would LOVE to do! From the bottom of my heart: THANK YOU!
Indeed. I see so many people on social media who try to paint all people with any belief in God as (figuratively and occasionally literally) flat Earthers. But that ignores the huge number of religious men through the ages who have advanced science. Not the least of which is Georges Lemaître who proposed what eventually became known as the Big Bang theory.
The argument that "huge numbers of religious men advanced science" is pointless since the vast majority of the population through the ages were "religious" at least publicly, given every major religion would likely execute them en masse otherwise. As for whether religious men in the past advancing science somehow implies that religious members today somehow add to the scientific process is preposterous. The reason religion is generally mocked is because it's the definition of unscientific dogma. "Faith" - which is what every single religion is built on can be succinctly defined as "belief without sufficient evidence".
@@davidalm2148 totally agree. Anything should be subject to criticism, including religions. Teachers have a duty towards the promotion of critical thinking, trying to fight an intrinsic idea in religion which threatens it should be applauded. Dogmatism is clearly not what is advancing science, quite the contrary.
Best scientific wording: - So, your conclusion after testing this device is that's producing no negative ion? - We're certainly not able to detect any negative ions.
I love how it's such a scientific way of thinking. We don't see one test and say it's 100%. We test our hypothesis over and over again before we even call it a "theory"
@@iwantitpaintedblack Not true, there are multiple reasons why a mass spectrometer may not detect ions. I myself have injected ions into a mass spectrometer and not seen any meaningful signal.
All of the scientific papers I've read claiming that they produce light weren't verifiable later on. Often the sample sizes were small, and there's very little research indicating these lamps are even _capable_ of lighting a room. The perceived effects could very well be due to the placebo effect, or some other source of light. :)
I've come to learn when someone is asked if they are an expert on something and they respond with anything other than "yes" or "no". That man is an expert.
I love when you visit a Scientist, and they don't just say "no it does nothing" they say "Interesting, well, let's go test this thing with a very specific machine I've been working on for the last 50 years."
maybe because it might not actually be true that something does something, or if it did in the past maybe it didnt in the future due to better technology edit: in other words, its cool
@@oneverymadlad1124 a sad truth, indeed. the ones who would visit an authority on a subject, and then ask for a second opinion, and then get frustrated when that second opinion coincides exactly, because they didn't get the answer the WANTED.
Mass spectrometers aren’t a very specific lab. I’ve been working in science and every lab I work on has had one (my current lab actually has dozens of them). They’re pretty much the most useful tool in chemistry!
@@AMK544 yes, fairly true. but, I more meant it's specific in what it does, it is not a heating mantle, or a beaker. like a microscope it has a fairly specific use. but...this is a comment from 2 months ago you're replying to. iunno what I was thinking at the time, nor care.
Demonizing it just serves to push people that believe it further into denial. Just like telling a cult member they're in a cult. Approaching it from a neutral stance helps everyone form a new opinion based on the presented facts rather than previously held opinions.
I think you misunderstand what is "pseudoscience". The scientific studies said that more studies are necessary to come to a conclusion. That is exactly the definition of science: hypothesis, trial, measuring results, analyzing data, modify/repeat until conclusions become clear. Pseudoscience is demonizing the scientific method in favor of a preconceived assumption of truth without actual science backing it up. So you would be following pseudoscience. Check out Veritsium's video titled "Is Most Published Research Wrong" to see where you have been tripped up: ua-cam.com/video/42QuXLucH3Q/v-deo.html
As a pilot, the part about ozone was the most interesting. Smelling ozone in an airplane usually means there is lightning nearby, along with static on the radios. We can also get St. Elmo's fire on the aircraft structure, so lots of ionization going on...but not very calming.

These things totally work. I had serious problems with a lack of chalky white mineral deposits on my desk. I got one of these lamps, and I got chalky white mineral deposits in spades.
Salt lamps do work! If they are plugged in. It was dark in my son's room, so as an experiment I only turned on the salt lamp. Conclusion, it works, I could now safely move around the room as all obstacles were now visible due to the light being cast in the room. To validate the experiment I turned off the salt light then attempted to cross the room. Outcome, I tripped on a pair of discarded sneakers, and I got a bruise from ramming my leg into the corner of the bed frame. YES, the light does work.
There is one problem did you perform the experiment with a control group. Are you able to cross the room during the day time? I’d be interested to hear the results.
I absolutely love scientists - like imagine working on one specific topic for 30 years and doings 100s of papers on it but you won’t claim to be an expert. They’re the best
I absolutely love how scientists maintain plausible deniability at all time. - "are you an expert in ions?" - "I've been studying ions for 55 years" - "so it's not emitting ions?" - "we certainly cannot detect any ions"
@@lukenajeeb8255 Basically the scientist is saying there might or might not be ions, the method proven to detect ions has not detected ions. With the expert comment he didn't say he's an expert, he's only studied them for 55 years, written papers about the aspects of ions. He doesn't throw bold claims, merely expel the data he has.
How can you possibly mistake stating the facts for plausible deniability? Did you discover the concept one month ago and decided to throw it at anything even remotely similar?
Even though they don't work in the slightest (my family never fell for that negative ion crap), the novelty of just having a rock that had a lightbulb in it was good enough for us :)
I love the answer of a true scientist to a subjectively graded question. "Are you an expert?" "I've... been studying my field for decades and written several papers on the subject."
Dunning Kruger Effect. People with little to no competence in a topic are very (overly) confident in their knowledge, while "true experts" (for which this guy most definitely qualifies) are more "humble" about their knowledge, always accepting the possibility that they dont know about something. For all intents and purposes, with decades of research and hundreds of papers published, he could have simply answered "yes", but decided to give the viewer his qualifications and let them decide for themselves. I really liked him in that moment^^
@@Yamyatos That's not what the dunning-kruger effect is. The dunning-kruger effect is when someone who's basically just stupid in general thinks they're much more intelligent than they are. It has nothing to do with being ignorant in a particular subject.
@@lordgarion514 Actually not. The dunning kruger effect is not about intelligence at all, but about knowledge / competence. Summarizing it in one sentence would be "an incompetent person cant know how incompetent he is". Not that it really matter tho, since the dunning kruger effect is more of a fun relation to mention online, since it's not actually brought up in any scientific debates a lot.
@@Yamyatos "In the field of psychology, the Dunning-Kruger effect is a cognitive bias in which people of low ability have illusory superiority and mistakenly assess their cognitive ability as greater than it is." "A cognitive bias is a mistake in reasoning, evaluating, remembering, or other cognitive process, often occurring as a result of holding onto one's preferences and beliefs regardless of contrary information. Psychologists study cognitive biases as they relate to memory, reasoning, and decision-making." TBH, you're simply wrong. And as you can easily see from the definition, just because someone has low ability doesn't mean they have the dunning-kruger effect working on them. But that does not mean the dunning-kruger effect is not caused by low ability. Just like only the flu viruses cause the flu, but just because you get the flu virus doesn't mean you're going to get the flu, but if you do then it was caused by the flu viruses.
@@lordgarion514 Robert Pruitt As you can see by the definition, the dunning kruger effect is not concerned about intelligence, as you claim it is. In the original paper Dunning Kruger (1999) tested people in social and intellectual tasks (humor, grammar, logic, ..) and found out that people who scored very low still believed they placed over average. He concluded, that people with low abilities regarding a specific field lack the ability to score high, but also the ability to recognize their lack of ability. That's why i earlier said the dunning kruger effect can easily be summarized in the statement "an incompetent person cant know how incompetent he is". This is easily applicable to most mental tasks, but does not reflect or make any statement about the intelligence of a person. It's not about intelligence, but competence (regarding a specific field / topic). Hope that clears things up a bit. If it does not then i dont know what will. Also, Wikipedia is a nice tool to get a rough idea about a topic, but it's wrong way more often than you might think. Normally i'd suggest reading the actual paper, but i'm not sure if it's available for free unless you currently work or study at an university.
Take a walk is great advice! But it's not just the exercise but the extroversion and space perception that helps. By orienting and looking outward you get space. Except some people are so stuck in their head, that while their eyes look outward, all their attention is still looking at past pictures in the mind and so they walk does little good because they are not mentally there, focus on the present and give attention to that.

I honestly have only heard about the ion thing with salt lamps very recently and never believed that. I had heard more that they help with slightly lowering humidity and helping dispel static electricity around electronics. I have one just because I have a really hard time falling asleep in total darkness but a salt lamp isn't bright enough to keep me up. And they are very pretty to look at which is nice.
Yes!! I love the lighting they give off, and the extra humidity protection is an even better plus especially when we've had water issues in the past. 😁
More people who were tricked into buying one in denial. There are a million other products that provide low light that aren't trying to trick you through outrageous claims. Stop it
@@deadpanfish I definitely wasn't tricked into buying one, I tried at least a dozen nightlights and adjustable lamps and all of them were still too bright. I actually didn't think a salt lamp would work either but my mom let me test one of her old ones out and with the light on the lowest setting it was about as prefect a match to the amount of light I wanted. It is a very nice warm glow, very similar to a candle or oil lamp that is very hard to get without using an open flame and is much safer. Even if they didn't have any benefits besides their appearance it still isn't fair to say that those who get them are idiots who are wasting their money. I personally think most modern minimalistic plastic/resin decor and appliances are bland and boring but I wouldn't tell others that they are wasing their money and are stupid to buy them just because that is their preference in decor. Everyone in this thread didn't get them because we think they are amazing cure all devices, we just freaking like the way they look and are appreciative of the few beneficial side effects they provide.
"Are you an Ion experct" "I've been studing them for 55 years" That's a real expert. Doesn't want to say yes because there's always more to learn. Just tells you his credentials and lets you decide if you think he's an expert.

I love how humble that man was, didn’t want to say he’s an expert after a mere 55 years of study. Contrary to the guy selling the salt lamp, he had all the answers with zero knowledge.
Good point on the comparison. I started college after 10th grade a "know it all", but now I often say that the most important thing that I learned at MIT was to say "I don't know". I learned it by seeing other experts speak like the one in this video. Once I can admit that what I know is a drop in an ocean of knowledge, it allows me to see that this ocean exists and gives me freedom to begin to explore it.
@@MrStanaland that’s an excellent point. I definitely won’t start at MIT after Sophomore year, but that is definitely something I need to remember. Thank you
The more you study, the more you learn that there's more to learn.
It was also refreshing how Veritasium interacted with the salt lamp seller, Derek wasn't confrontational or arrogant. He wasn't trying to prove the seller wrong or make the seller feel guilty, because he knows that the seller guy just has the wrong info, and that's why he made this video, to give the right info to the people who need it. This is the type of education I like to see, one that doesn't talk down to the uneducated.

"So, your conclusion is that it's not producing any negative ions?"
"We certainly aren't able to detect any ions."
I love his response. It's such a humble, carefully worded, and scientific response. He doesn't say definitively that the salt lamp is not producing ions, just that they simply are not detecting any ions from the salt lamp. It is a subtle but important distinction, and a great example of how easy it is to develop hubris from literally anything if you're not paying attention to yourself. The scientific community - no, the _world_ needs more of this.
i noticed that too, pretty smart of him to word it like that
Alternative perspective is rigor. Rigor and humility may be associated but in this case I tend to focus on the rigor more. I personally practice rigor a lot, on a daily basis, and in casual conversations, rigor may not always be desired. In communication, it seems we oftentimes face a tradeoff between the accuracy of the statements and the cognitive load on the humans.

I adore how when Derek asks "are you an ion expert" the answer isn't yes or no. It's "here is my level of experience in the field." which gives you a way better idea of why you should listen than just "yes i am"
True, but I think we can safely say that after working for _55 YEARS_ in the field, this man is indeed an expert.
@@nob2243 It’s widely accepted that 10.000 hours is the average time it takes to be considered an “Expert” in something.

I liked his response, too.

For some reason I thought they were meant to remove moisture in the air? I don't know why I assumed that. I never knew anything about the ions until this video.

The thing with the thunderstorms, oceans and beaches is that they are already quite exciting on their own - so it's normal to feel different/better when experiencing them.
I was wondering how the effect would compare if you put a small fountain of water in your home or office, or even a recording of waterfalls or ocean waves. Also if the ionized air is creating a breeze, has that been tested against a gentle fan for creating the impression of fresh air?

@@ToonedMinecraft
I didn't hear the participants were told to pay attention if they got happier during the experiment. So, they didn't know this could be one of the reactions.
In short, academics will only accept ions have a positive effect on humans only if they get an affidavit, signed by the ions themselves, that they influence in a positive way health and mood of humans.
@@O-Kyklop lol. Yeah, that's totally how science is done.
@@CyberSway
Yeah. And worse. Much investigations have been done, during the XIX and beginnings of the XX century, where one discovery was that humans cells can emit and receive EM waves.
And we got this guy here asking himself if ions have an influence on the human body and mind. And because he knows, the answer must be "No", he overlooks even positive results confirming that ions have that influence.
@@O-Kyklop you have a very conspiratorial mindset.
I just love how the scientist are so open-ended with their responses. None of them said absolutely not to any experiment. They all said stuff like " i believe or, or it appears to be that way".
hat's the point of science! If you ever hear anyone say something along the lines of "I absolutely know," they're either lying or trying to sell you something.
@@erich930Typically I would use something more along the lines of "The evidence resulting from this experiment supports the claim/argument that...," rather than a statement of personal belief in the claim.
Many scientists do this as a faux humility though. Then under the pressure of the pandemic most of them went crazy for masks and vaccine mandates at Caltech, which was the opposite of being humble or scientific.
@@commscan314 It's unfortunate that doesn't work in day-to-day conversations with, say, your parents, friends or family. People that aren't scientific minded get bored, or don't internalize it if you say it that way.
See Veritasium's video about anecdotes vs data (idk the current title, but if you look for "anecdotes veritasium" you'll find it)
A compromise I like to use is to reply with "yes, most likely" or "it does seem that way" then add an anecdote. Normal people take that more seriously this way.
That's literally how science works, genius. I know your democrat friends taught you the concept of "The Science is Settled", but no scientific theory is ever "settled". This language is not only normal, it's how it's supposed to be.

I think the way the video is presented does a fantastic job of showing how impressionable we are. If a viewer paused at various points and walked away they would leave with a totally different viewpoint because we don't tend to continue with our own research, instead trusting the presenter to be honest (or at least not motivated by funding or advertisers).
I have never believed that salt lamps have any benefit for the health, chemically speaking.
However, I do believe that their warm, pinkish, orangish glow is good for mood. And they look very cool.
The package of the salt lamp I bought wrote, it has a calming effect. I like the soft, warm light. I like to think that these lamps do help to calm down. I set the lamp near my bird cage. I have canaries and they often wake up during the night or are awake for too long. Every time I turn on the lamp they sleep better.
Well if you believe it, it must be true.
@@lucrative6477 the placebo effect is very real and entirely based on belief
salt is the ingredient. People use salt inhalers to improve airways. People pay to travel to get therapy in salt caves. And if these are run for some time they do shed the salt around the lamp so I always put my salt lamp on a saucer or plate.

I think another important thing to point out about the ion "tests" is that doing these tests in things like office settings is a great way, experimentally-speaking, to get a positive result without knowing if you've identified the correct cause. Sure, people probably do notice an improvement in mood and general behavior when an ionizing air purifier is put into the room, but that doesn't just change the ion content of the room. I could very easily imagine introducing an air purifier to an office that previously didn't have one would improve air quality *in general* and improve air flow in a room that's probably rather stuffy otherwise.
Sure, it could be the ions... but it could also be a lot of other things.
It’s most likely not ions.
But if they are periodically turned on and off and then see a difference in performance, it would prove it, like they did
@@simoringenfreitag5603not necessarily because turning off the purifier would also change the airflow back to how it was.
@@simoringenfreitag5603 Yeah but what if the air purifier produced a sweet smell like the one tested in this video? That would also obviously impact productivity. The point was a lot of the studies, including that one, were poor quality.

We cannot have science, if we do not test things.
Rather sure they scripted that and he was aware of what would happen.
That is science. You have to test it.
@@kolelokaram8541 Without the "but". Being skeptical includes being skeptical of the things you know, and basing your assertions on that which has more evidence. Be skeptical that negative ions AREN'T good for you, gather some evidence and conclude. You might discover something along the way
I also love how the professor spoke like a true scientist:
Veritasium: "It's producing no negative ions"
Dr. Dalleska: "We're certainly not able to detect any negative ions"
There is always that very very small chance that it is indeed producing, but we're not able to detect it. So as a scientist you can't say with absolute certainty that it is not producing.
My entire life I got bad grades in school. Geography was the exception because of the passion I had for Nature... So it was easy to learn something I intuitively understood. But...

i really like how you portray the narrative around this subject. You start off by explaining all the reasons why negative ions are good for us, show us a giant stack of papers written about the subject, and give an example of a study showing positive results. Only to come in at the end and show how despite all that, the claim is not proven at all. This is a good representation of how we should never believe something just because it seems to be true.
Also, just because a paper (or many papers) is written supporting something, doesn't mean it's true. The quality of the evidence makes a big difference.

I also like that professor who doesn't just answer "yes" to being an expert, but rather gives his credentials like any true scientist would and leave it at the listener's discretion to determine expertise (because a real expert would know there's always more to learn). Even more fascinating is that there really IS a crystal that will produce ions when heated, a shame it's too expensive for normal sales purposes.

This video is just one example of how much information and explanation it takes to disprove a statement someone makes in less than 2 seconds. This is why things like "alternative facts" persist: no one has the patience to actually learn things.

This is so true and I wish more people would realize it
I feel like most people don’t know what Alternative facts are. That was just someone saying that “my research contradicts yours” in a very poorly worded way.
Its worse than that though.
Its not just about disproving things that aren't true, but its also that its really difficult to go through "peer reviewed literature."
Honestly, unless you are at least working on a graduate degree, its probably a waste of time to mess with the incredibly tiny details of peer reviewed research.
I know there are problems with news journalists, but generally the best source of looking critically at a claim is simply asking "what is the mechanism by which this assertion works."
Quickly you get the explanation about some production of serotonin and then you consider how few negative ions you breathe in relative to all the atoms you breathe in and you quickly see how ridiculous the claim is.
You don't need to mess about with research and studies, just use common sense. That's going to get the lay person way further than mucking through details that ought to be left to people who have nothing else better to do.

I'm not even in college and that statement made me cringe
Serotonin is the transmitter house of the cell power.
My research has absolutely nothing to do with it, and that alarmed my sham detectors. I would've instantaneously noped out of there.

Finer sand beach has more negative ions. You will get 20x more negative ions in your bathroom on average with warm shower running. Cold air conditioning will generate net/more positive ions.
That salesman basically claimed the lightbulb inside the lamp was hot enough to sublime salt, but still safe to have turned on in close proximity to people.
Technically sumblimation is a matter of pressure not temperature. With high temperature the salt would melt not sublimate.
@@Rig0r_M0rtis sublimation is the phase transformation directly from solid to gas. It is a line on the pressure/temperature phase diagram of a material, so sublimation temperature will depend on the pressure. At some pressures there will be no sublimation because the liquid phase can exist. But as an example, CO2 has a sublimation point at ambient pressure, which is the reason why dry ice exists.
But for NaCl at atmospheric pressure it will melt and then boil, so no sublimation.
@@wouterbaake7386 yeah, so? That's just what I said.
@@Rig0r_M0rtis Just clarifying that sublimation is not a matter of just pressure but a combination between temperature and pressure

Well, I have three salt lamps, and I've always been skeptical to the whole negative ion thing. I still enjoy them because they are nice to look at, and provide a nice level of low light conducive to my circadian rhythm in the evening. What I especially like about this debunking is that anyone who has these lamps can go forth and spend less money in the long run on both bulbs and electricity by using LED night light bulbs instead, because who cares if it produces less heat.

For many years now Ive been subscribed to your channel & I can honestly say, I always get excited EVERY time I see a notification that you have uploaded a new video. I have learned so much from your channel! I want to thank you for your hard work & for encouraging all us young people to not only pursue physics, but also not to be dismissive of other people's points of view. Youre open minded yet unlike many academics, I have never heard you be dismissive of the fact someone might be religious or spiritual & that they want to be a man of science, (something that two of my professors do all the time). You are the reason I decided to choose to get my undergrad in physics with the hope that when I finish my undergrad here at Carnegie Mellon, I can get my PhD in astrophysics. I still have two more years..... if school isn't tough enough, the fact that I have to work makes it really tough but its so worth it! You were a big part of my decision to pursue physics & by doing so, I found out that the pursuit of knowledge through the world of physics is not simply want I want to do for the rest of my life, its what I would LOVE to do! From the bottom of my heart: THANK YOU!
Whoa! This inspires me. I wish you all the best!
Indeed. I see so many people on social media who try to paint all people with any belief in God as (figuratively and occasionally literally) flat Earthers. But that ignores the huge number of religious men through the ages who have advanced science. Not the least of which is Georges Lemaître who proposed what eventually became known as the Big Bang theory.
We miss you dude .... no homo...
The argument that "huge numbers of religious men advanced science" is pointless since the vast majority of the population through the ages were "religious" at least publicly, given every major religion would likely execute them en masse otherwise.
As for whether religious men in the past advancing science somehow implies that religious members today somehow add to the scientific process is preposterous.
The reason religion is generally mocked is because it's the definition of unscientific dogma. "Faith" - which is what every single religion is built on can be succinctly defined as "belief without sufficient evidence".
@@davidalm2148 totally agree. Anything should be subject to criticism, including religions. Teachers have a duty towards the promotion of critical thinking, trying to fight an intrinsic idea in religion which threatens it should be applauded. Dogmatism is clearly not what is advancing science, quite the contrary.

All of the scientific papers I've read claiming that they produce light weren't verifiable later on. Often the sample sizes were small, and there's very little research indicating these lamps are even _capable_ of lighting a room. The perceived effects could very well be due to the placebo effect, or some other source of light.

Demonizing it just serves to push people that believe it further into denial. Just like telling a cult member they're in a cult. Approaching it from a neutral stance helps everyone form a new opinion based on the presented facts rather than previously held opinions.
I think you misunderstand what is "pseudoscience". The scientific studies said that more studies are necessary to come to a conclusion. That is exactly the definition of science: hypothesis, trial, measuring results, analyzing data, modify/repeat until conclusions become clear. Pseudoscience is demonizing the scientific method in favor of a preconceived assumption of truth without actual science backing it up. So you would be following pseudoscience.

"In the field of psychology, the Dunning-Kruger effect is a cognitive bias in which people of low ability have illusory superiority and mistakenly assess their cognitive ability as greater than it is."
"A cognitive bias is a mistake in reasoning, evaluating, remembering, or other cognitive process, often occurring as a result of holding onto one's preferences and beliefs regardless of contrary information. Psychologists study cognitive biases as they relate to memory, reasoning, and decision-making."
TBH, you're simply wrong.
And as you can easily see from the definition, just because someone has low ability doesn't mean they have the dunning-kruger effect working on them. But that does not mean the dunning-kruger effect is not caused by low ability.

Robert Pruitt
As you can see by the definition, the dunning kruger effect is not concerned about intelligence, as you claim it is.
In the original paper Dunning Kruger (1999) tested people in social and intellectual tasks (humor, grammar, logic, ..) and found out that people who scored very low still believed they placed over average. He concluded, that people with low abilities regarding a specific field lack the ability to score high, but also the ability to recognize their lack of ability. That's why i earlier said the dunning kruger effect can easily be summarized in the statement "an incompetent person cant know how incompetent he is".
This is easily applicable to most mental tasks, but does not reflect or make any statement about the intelligence of a person.
It's not about intelligence, but competence (regarding a specific field / topic). Hope that clears things up a bit. If it does not then i dont know what will.
Also, Wikipedia is a nice tool to get a rough idea about a topic, but it's wrong way more often than you might think. Normally i'd suggest reading the actual paper, but i'm not sure if it's available for free unless you currently work or study at an university.

it absolutely does work as a bit of a dehumidifier. i watched this video as a result of my lamp sitting in a puddle after a rainy day!
More people who were tricked into buying one in denial. There are a million other products that provide low light that aren't trying to trick you through outrageous claims. Stop it
@@deadpanfish I definitely wasn't tricked into buying one, I tried at least a dozen nightlights and adjustable lamps and all of them were still too bright. I actually didn't think a salt lamp would work either but my mom let me test one of her old ones out and with the light on the lowest setting it was about as prefect a match to the amount of light I wanted. It is a very nice warm glow, very similar to a candle or oil lamp that is very hard to get without using an open flame and is much safer. Even if they didn't have any benefits besides their appearance it still isn't fair to say that those who get them are idiots who are wasting their money. I personally think most modern minimalistic plastic/resin decor and appliances are bland and boring but I wouldn't tell others that they are wasing their money and are stupid to buy them just because that is their preference in decor. Everyone in this thread didn't get them because we think they are amazing cure all devices, we just freaking like the way they look and are appreciative of the few beneficial side effects they provide.
"Are you an Ion experct"
"I've been studing them for 55 years"
That's a real expert. Doesn't want to say yes because there's always more to learn. Just tells you his credentials and lets you decide if you think he's an expert.
me and my brother who says anything about relearning? There’s always more questions upon more discoveries when it comes to science. Smh
Autistic or not, you’re the one lacking wisdom.
@me and my brother eh autism does have some positives
Dunning Kruger at its finest
@me and my brother It's really simple minded to assume someone has a mental issue based on their field of interest. It's dedicated people the like man in the video whose work has made our lives as comfortable as they are.
Todo McGillicutty He should have said he had been studying them for eons
Yes, salt lamps work: they glow and if you lick them, they taste salty.
Everything you could want of a salt lamp!
I'm teaching mine to get the newspaper for me
So far... unsuccessful

I placed some headphones on it playing David Goggin's audiobook on a loop.
We'll keep ya'll updated.
The title of the video asks a question. The thumbnail answers the question. Thankyou. I don't ask for much in life.
