  • 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.

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.

I learned it by seeing other experts speak like the one in this video.

    • 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.

  • 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.

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.

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.

    • 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 so glad you put a logical and scientific explanation to this craze that gets so misused by certain people.. no offense. The things are still awesome, I collect rocks so I appreciate minerals, crystals but I don't think they heal me in anyway other than the benefit I get mentally and physically by going out and gathering them in Nature, exercising as I collect and gather rocks and hike my dogs. That alone. That experience, the act of exploring, hunting, finding. Is so beneficial to my soul and mind. Then just being out in the woods here in Oregon and exploring the woods is the best type of therapeutic experience for me. It's like active meditation because even tho I am not sitting in one place - I am in a state of hyper awareness and I get in tune with my observation skills more and more each time I go exploring in the woods. There is just something magical about going on a walk in the wilderness by yourself and with your dog. Or, just by yourself if you don't have any dogs. The experience of hiking alone innately teaches you a lot, even if it's subconsciously. Nature is a amazing teacher, and you can learn how to be more connected to yourself, just by practicing going on solo hikes in the woods. (The one thing I am facinated about, is the effects scientist's have found Magnetic field waves are showing medicinal benefits and I'm curious to see where that field of science is going to go and evolve to...? 🧲🧠👍🏻)
