We're not out to cut funding to your black hole detection chamber or revoke the degrees of chiropractors just because a couple of us don't believe in it, okay? Chill out, participate with the prompt and continue with having a nice day. I'm sure almost everybody has something to add.

The idea that SSRI antidepressants work by increasing serotonin levels. If that were the case, why don't they start working immediately? Instead, most people don't see positive effects for several weeks.

Full moons do not have an impact on people with mental illness, make weird things happen, increase work load, or increase the chance of going into labor. I have worked in three separate hospitals in three separate states and the consensus is: full moons bring out the crazies and the babies.

[–] [email protected] 0 points 10 months ago (1 children)

I believe there have been multiple studies that found that full moons affect most people sleeping and make sleep a bit harder

[–] [email protected] 1 points 10 months ago

I sleep in a completely blacked out room yet I know when it's near the full moon because my sleep gets very broken and restless.

[–] [email protected] -1 points 10 months ago

It's not true. Your observations may be affected by confirmation, bias, or other things.

However, barometric pressure can apparently induce labor

That mothers shouldn't co-sleep with infants. Every other primate I know of co-sleeps with their offspring. Until very recently every human mother co-slept with her infants, and in like half of the globe people still do. Many mothers find it incredibly psychologically stressful to sleep without their infant because our ancestors co-slept every generation for hundreds of thousands of years.

I would bet money that forcing infants to sleep alone has negative developmental effects.

[–] [email protected] 2 points 10 months ago (3 children)

The reason for this is that we tend to sleep deeper now than our ancestors. Because of this, we are more prone to roll onto a baby, and not wake up.

It can still be done, you just have to avoid things like alcohol, that stop you waking. You also need to make sure your sleeping position is safe. Explaining this to exhausted parents is unreliable, however. Hence the advice Americans seem to be given.

Fyi, if people want a halfway point, you can get cosleeping cribs. They attach to the side of the bed. Your baby can be close to you, while also eliminating the risk of suffocating them.

[–] [email protected] 1 points 10 months ago (1 children)

I think something on the UK's NHS implied the risk is primarily for mothers with various kinds of problems (including drug or alcohol abuse). Made me wonder if it's largely recommended for everyone to cover the many people who are at risk but don't want to think they are.

The Big Bang being a singular event that only happened once, as if we are so special we just happen to be at the point of time, within the spectrum of infinity where matter is in a state that can support life. (I'm not aware if that's the prevailing theory anymore)

Also the double slit experiment. We aren't a phantom observers, we are impacting the experiment. With our equipment.

[–] [email protected] 0 points 10 months ago* (last edited 10 months ago) (1 children)

On your second point, that's what the science actually says. "Observer" or "observation" is used in a scientific sense and was probably a poor word choice. Science journalism gets carried away with anything that has the word "quantum" in it and it drives us mad.

You're absolutely right that the mechanism that's causing the wave function to collapse is the presence of whatever piece of equipment the particle is hitting. Whether that collapse happens at the two slits or the back wall changes the pattern, and that change is what shows wave-particle duality.

Also: physics doesn't claim to know that the Big Bang only happened once. That's just as far back as we can rewind with our current models. This is again something that science journalism takes a lot of liberty with.

I’ve always thought the classic Hunter - Gatherer gender division of labor was bullshit. I think that theory has gone out of fashion but I always thought it seemed like a huge assumption. It seems so much more plausible to me that everybody hunted some days (like during migration patterns) and gathered others. Did they even have the luxury of purely specialized roles before agriculture and cities?

Another reason I think that is because prehistoric hunting was probably way different than we imagine. Like, we imagine tribes of people slaying mammoths with only spears. It was probably more traps and tricks. Eventually, using domesticated dog or a trained falcon or something.

[–] [email protected] 1 points 10 months ago* (last edited 10 months ago) (1 children)

I always assumed that hunter gatherer division was mostly down to the individual, some traits make some better at hunting than others.

I struggle to locate static objects, I for the fucking life of me just can't see it. I'll be looking for something and either look right over it or walk past it multiple times

But if I go outside and look in the trees I can spot all the squirrels within seconds. Not like that's a talent or anything special, but my point is that I'd starve if I had to look for food in the brush, and likely I imagine these types of traits are what defined who did what job, meaning who was good at what, and likely considering lots of hunting was endurance based and not skill based at all, then most adults probably participated to some degree.

I've also gone shroom hunting and had to come back empty handed because I can't see the god damned things.

You can read the dawn of everything book which is a very interesting take at a lot of those assumptions which are indeed false. This book goes deep into the ideological bias scientists have when interpreting evidence.

cut funding to your black hole detection chamber

I knew you'd come for my fucking black hole detection chamber you swine

[–] [email protected] 1 points 10 months ago

First they came for the black hole detection chambers and I said nothing because I was researching Computer sciences.

Then they came for my HPC clusters

The idea that animals do not have feelings. I don't believe complex thought is necessary for emotion. You can take away all our human reasoning, and we would still get mad, or sad, or happy at things.

[–] [email protected] 1 points 10 months ago* (last edited 10 months ago)

that comes from religion not science

[–] [email protected] 1 points 10 months ago* (last edited 10 months ago)

I don't think there is a scientific concensus on this. We are constantly finding previously unknown similarities between the minds of other animals and humans. I've put together a small lemmy community on animal communication and digital bioacoustics, it is somewhat related to this stuff.

If anything I think emotional response is the least advanced part of a human mind. However, if we're talking about brains of sharks, small lizards, or ants then I think emotion would be a word with a lot more nuance than whatever it is they do.

[–] [email protected] 3 points 10 months ago

It's definitely NOT science that animals don't have feelings. Maybe 50 years ago.

Now, there's a concerted effort to discern thoughts and emotions in animals.

Psychologists branding everyone with a disorder. You can spend a whole lifetime trying to understand yourself and you won't. 4 years of schooling and a book full of labels doesn't give you any extra magical understanding of everyone else.

[–] [email protected] 1 points 10 months ago (1 children)

4 years where? To become a real psychologist (not a therapist) in most places you need a PhD or a PsyD. In total, you probably do at least 8 years of schooling.

Not to mention that that "book full of labels" is constantly reviewed and was made based on consensus from psychiatrists, which are medical doctors with a lot more than 4 years of schooling.

You know I felt this way for years. I felt that way through psychopharmacology in pharmacy school, and I felt that way during our psychiatry and behavior lectures in medical school. I felt like psychiatry was minimizing behavior to these boxes was far too reductionist. Then I spent a month in an inpatient psychiatry facility as a third year medical student.

While I completely agree that each individual is unique and people are more than their diagnosis, you'd be absolutely shocked by just how similar patients' overall stories, maladaptive coping mechanisms, and behaviors are within the same psychiatric illness. I can spot mania from a doorway, and it takes less than five minutes to have a high suspicion for borderline personality disorder. These classifications aren't some arbitrary grouping of symptoms: they're an attempt to create standard criteria for a relatively well preserved set of phenotypic behaviors. The hard part is understanding pathology vs culturally appropriate behavior in cultures you don't belong, and differentiating within illness spectra (Bipolar I vs II; schizophrenia vs bipolar disorder with psychotic features vs schizoaffective)

Dark matter. Sounds like a catch all designed to make a math model work properly.

[–] [email protected] 3 points 10 months ago* (last edited 10 months ago) (1 children)

Yeh, that's how the scientific method works.
Observations don't support a model, or a model doesn't support observations.
Think of a reason why.
Test that hypothesis.
Repeat until you think it's correct. Hopefully other people agree with you.

People are also working on modifying General Relativity and Newtonian Dynamics to try and fix the model, while other people are working on observing dark matter directly (instead of it's effects) to further prove the existing models.

We are in the "testing hypothesis" stage. And have been for 50ish years

[–] [email protected] 0 points 10 months ago (1 children)

Yeah, it's legitimate science being done, but some people treat it as sacred and would fight you to no end because they say Dark Matter is some certainty, rather than approaching it with the proper scientific skepticism or with a statistical outlook.

For the most part believers in Dark Matter are cool, but a vocal minority practically worship it as the only possible truth.

[–] [email protected] 0 points 10 months ago (1 children)

The certainty is that there is something there, we just don't know what it is. The name "dark" anything is irrelevant.

[–] [email protected] 0 points 10 months ago (1 children)

If a new hypothetical model showed that either some far off unobserved mass(es) or the currently observable mass can have the gravitational effects that were previously explained by dark matter, or any other far off idea about the nature of gravity at large scale: then there would be evidence there is nothing there. Currently there is no evidence that something is there, just that there are forces and motions that are not understood.

[–] [email protected] 0 points 10 months ago (1 children)

Great example, and this brings up a great point about this topic - there's a difference between what's a scientific pursuit vs. what is current established scientific understanding.

Dark matter is a topic being studied to try to find evidence of it existing, but as of now there's is zero physical evidence that it actually exists.

[–] [email protected] 4 points 10 months ago

You’re not wrong. According to the current scientific understanding of the universe, that’s exactly what it is. They just gave it a badass name.

[–] [email protected] 0 points 10 months ago (1 children)

I know, I was so hype a few years ago when a new gravity well model supposedly eliminated the need for Dark Matter, but recently it's been in the news as a scandal that also doesn't fix everything.

[–] [email protected] 1 points 10 months ago

Modified Newtonian Dynamics (MOND). It's been the dissenting voice in the modern Great Debate about dark matter.

On one side are the dark matter scientists who think there's a vast category of phenomenon out there FAR beyond our current science. That the universe is far larger and more complex than we currently know, and so we must dedicate ourselves to exploring the unexplored. The other side, the

On the other you have the MOND scientists, who hope they can prevent that horizon from flying away from them by tweaking the math on some physical laws. It basically adds a term to our old physics equations to explain why low acceleration systems experience significantly different forces than the high-acceleration systems with which we are more familiar -- though their explanations for WHY the math ought be tweaked I always found totally unsatisfactory -- to make the current, easy-to-grock laws fit the observations.

With the big problem being that it doesn't work. It explains some galactic motion, but not all. It sometimes fits wide binary star systems kind of OK, but more often doesn't. It completely fails to explain the lensing and motion of huge galactic clusters. At this point, MOND has basically been falsified. Repeatedly, predictions it made have failed.

Dark matter theories -- that is, the theories that say there are who new categories of stuff out there we don't understand at all -- still are the best explanation. That means we're closer to the starting line of understanding the cosmos instead of the finish line many wanted us to be nearing. But I think there's a razor in there somewhere, about trusting the scientist who understands the limits of our knowledge over the one who seems confident we nearly know everything.
