When you find out about Dunning-Kruger and realise that that's why everyone else in the world is so stupid apart from you.

[–] Conradfart@lemmy.ca 79 points 2 years ago (1 children)

Unlike most people, I see what you did there.

grabs popcorn to watch inevitable argument about mean vs median

Central Limit Theorem 🤝 Me in first year stats

"Mean and Median are the same"

I'll be "IQ is a normalized distribution", someone else take "IQ isn't intelligence"

[–] Eylrid@lemmy.world 4 points 2 years ago

I'll take "IQ is a flawed measure of intelligence, but intelligence is probably still normally distributed"

I sometimes genuinely expect people to know "basic quantum mechanics" and I'll start ranting about it as if they have some background knowledge and then when I saw the moon might not exist if I don't look at it my roommate looks at me like I'm crazy.

The funniest part of this comment to me is that it could be said unironically either by someone educated in college or on tiktok

I sometimes expect people to know "basic physics," which is apparently a bit much to ask sometimes. I don't mean having a firm grasp on what e=mc² actually means, I don't even have that. I'm talking about a firm grasp on energy simply being the capacity to do work, and the basic fact that there is no free energy device.

No, you cannot charge an electric car while it's driving by putting wind turbines on it. No, you cannot use gear ratios to achieve overunity. No, magnets can't solve the problem either.

PS, if you firmly believe that crystals vibrate on higher frequencies (eta: and that vibration can somehow heal you or something), but can't describe what frequency amethyst vibrates at in hertz, you are what Dunning and Kruger set out to study

[–] starman2112@sh.itjust.works 13 points 2 years ago

I got curious, so I googled it. There's a company that sells amethyst that claims it vibrates at 32,876 Hz. They do not describe anything about the physical characteristics of the particular rock they measured, which would have an impact on the frequency at which it vibrates.

Another source claims amethyst resonates with the Crown chakra, which has a frequency of 768 Hz. They do not explain how they derived this frequency. 32,876 is not a multiple of 768, and would not resonate with something that vibrates at that frequency.

Yet another source claims that amethyst vibrates at 963 Hz. It does not list any physical characteristics of the rock they measured, and this is not a multiple of either of the other numbers.

Credit to Beadworks Philadelphia for explaining that different objects have different resonant frequencies, even if they're made of the same material! Unfortunately, that credit is revoked because they immediately claim that amethyst crystals can cure or treat medical conditions. Shame.

I'm not a physicist, but I think crystals can vibrate at a fixed frequency? Isn't that how quartz watches work?

[–] EpeeGnome@lemmy.fmhy.net 8 points 2 years ago

A crystal's resonant frequency is determined by its size and shape as well as it's material. The quartz crystals used in watches and other precision crystal oscillators are machined very exactly. Even then it's not that they can't vibrate at other frequencies, they're just not good at it.

[–] starman2112@sh.itjust.works 5 points 2 years ago* (last edited 2 years ago) (1 children)

Yes and no. The quartz in watches needs to be tuned to a specific frequency. They do this by either adding material or taking some away, just like a normal tuning fork. Here's a video explaining it better than I possibly can, and it's Steve Mould, so you know it's worth the watch

[–] pudcollar@lemmy.ml 3 points 2 years ago

ahh worth the watch

[–] sharkfucker420@lemmy.ml 2 points 2 years ago

Dunning Kruger etc etc

[–] Dr_Cog@mander.xyz 14 points 2 years ago (2 children)

I do the same with psychology. Except it's worse because people think they DO know psychology when they absolutely don't

[–] sharkfucker420@lemmy.ml 18 points 2 years ago (1 children)

I'm so glad I don't have to deal with people pretending to know physics that often. Usually I just get "why the fuck did you major in physics" and then I go cry

[–] RojoSanIchiban@lemmy.world 16 points 2 years ago (1 children)

I'm assuming you wish you'd gone for marine biology instead, sharkfucker420?

[–] sharkfucker420@lemmy.ml 6 points 2 years ago

You could say that

[–] Spzi@lemm.ee 9 points 2 years ago (1 children)

This is telling a lot about your psyche.








;)

[–] Dr_Cog@mander.xyz 8 points 2 years ago (1 children)

And how does that make you feel?

[–] Spzi@lemm.ee 1 points 2 years ago

Makes me smile, but ... Dr. Cog, can you try a bit deeper?

[–] funnystuff97@lemmy.world 72 points 2 years ago (5 children)

I mean, pulling it back for a second, what the fuck would an "abstract study" even be about? What, would you publish the results of your thought experiment?

[–] Spzi@lemm.ee 56 points 2 years ago (1 children)

An abstract study has yet to be implemented. You cannot run an abstract study on it's own. Otherwise, it can be about anything.

for non programmersAn abstract class is a concept in programming.

[–] mindbleach@sh.itjust.works 12 points 2 years ago

void* study();

[–] fossilesque@mander.xyz 22 points 2 years ago (1 children)

Journal of Philosophy would like a word.

[–] xantoxis@lemmy.world 9 points 2 years ago

Also every scientist who works in theoretical disciplines.

[–] Kolanaki@yiffit.net 7 points 2 years ago (1 children)

I was actually wondering this the other day. Could I be so abstract that I don't even really say anything useful at all in the paper, but still make it sound like there's something to it? 🤔

[–] troyunrau@lemmy.ca 3 points 2 years ago (1 children)

So basically anything made by ChatGPT? ;)

[–] frezik@midwest.social 1 points 2 years ago

AI generated nonsense has been published before. Even got by peer review. That was even before ChatGPT.

[–] Liz@midwest.social 2 points 2 years ago

Clearly it's a meta analysis of abstracts.

[–] Hedup@lemm.ee 1 points 2 years ago

It's just a study done on a higher abstraction level. Like looking at CPU as a collection of logic gates instead of transistors. Or programming in C instead of assembly.

[–] CareHare@sh.itjust.works 24 points 2 years ago

Same problem in the abstract art business. Too many artists publish only a summary of their painting or song, instead of the whole deal.

[–] secondaccountlemmy@lemmy.world 13 points 2 years ago (2 children)

What's the context for this?

[–] TexMexBazooka@lemm.ee 54 points 2 years ago

A summary of a scientific paper is called an abstract, it’s a stripped down version of what the paper is covering.

The joke is that this person is not scientifically literate enough to understand that “abstract” in this context has a different meaning than in other fields of study like art

[–] fossilesque@mander.xyz 36 points 2 years ago

It's abstract, you wouldn't get it.
