Why do so many people discount psychedelics?

Either they're "just drugs", or they are without a doubt the most profound and culturally significant pharmacological discovery ever. I don't know which one but I'm inclined to go with the latter.

These abstract modes of consciousness legitimately exist in this universe - they are REAL. Ignore the cultural bias of the association between psychedelics and hippy nonsense like astrology and religion. The psychedelic state of mine is real and it exists.

Clearly there are enormously varied parameters on consciousness. What the fuck even is consciousness? Is it just an emergent property of computation or pattern recognition? It is a property of the universe itself and as such it falls under the purview of physics, not philosophy as some people dismiss it to be.

LSD is useful in research because it causes the brain to process all information equally without checking whether it's already archived an opinion on some of it. It quite literally causes you to discard your preconceptions and prejudices.

>The time will come when diligent research over long periods will bring to light things which now lie hidden. A single lifetime, even though entirely devoted to the sky, would not be enough for the investigation of so vast a subject... And so this knowledge will be unfolded only through long successive ages. There will come a time when our descendants will be amazed that we did not know things that are so plain to them... Many discoveries are reserved for ages still to come, when memory of us will have been effaced.
― Seneca, Natural Questions

Do you think we are an intelligent species? Or are we nothing in comparison to the potential for organic life such as ourselves, and we're just trapped in an evolutionary local maximum with respect to intelligence?

>Do you think we are an intelligent species?
Yes and the evidence is that I think so.
>Or are we nothing in comparison to the potential for organic life such as ourselves
This is a hard question to answer because we haven't met a more intelligent life form than ourselves and we know too little about our brain to ascertain how much more powerful such an organ can be. Some aspects of nature may seem beyond human comprehension, but that may be because we haven’t yet found a clever way to abstract them. Maybe our brain is adequate for the task, but we know too little to make sense of everything.

>Do you think we are an intelligent species?
We are the most intelligent life that we know can exist. We are the smartest general intelligence currently alive, at the very least on Dirt.

>Or are we nothing in comparison to the potential for organic life such as ourselves, and we're just trapped in an evolutionary local maximum with respect to intelligence?
We are extremely far form the smartest possible intelligence. I'm not sure what the biological limit to intelligence is, as it's a pretty delicate system, but we can surely invent a AGI that is smarter than us.

As far as whether we will evolve to be more intelligent, probably not. There are no evolutionary pressures for intelligence, and we like to jerk ourselves off for helping the less fortunate, which means that not only do we not encourage smart people to live, we try to keep the dumb people around, too.

Possible dangers of melatonin? Anyone used it for an extended period of time? I've read from a couple sources that you should be taking just ~.3 grams, as opposed to the 5 grams most stores will sell you. I have a lot of trouble sleeping, and yes I've tried turning off electronics hours before bed, being active in the day, clean sheets, proper sleeping posture, using blue light filters, essential oils, and whatever else I'm not remembering. And to keep this science related, is it ethical to sell a drug with so little research on it? Currently it's only sold over the counter in the US.

No known benefits unless you've recently changed your sleep cycle and then very minor benefit. You'll be fine

Get rid of wi-fi and stop using a cell phone. Bluetooth, etc, as well.

There's a reason your body isn't properly making its own melatonin, at the proper times, in the proper curve.

Hello, i want to ask /sci/ their opinion about Euarchontoglires phylogeny. I want to establish clear ideas about this, but sadly i have no resources to make an analysis on molecular grounds. But at least on morphological grounds, i want you to consider the following:

We can find 3 different structures of the postorbital ring in Euarchontoglires: The first in Ptilocercus lowii and the entire Primates order; the jugal makes a complete arch up to the superior segment of the eye socket and is itself separated from the lacrimal. The second in Glires and Scandentia minus P. lowii (Tupaiidae), here the arch formed with the jugal is much shorter and is completed by the frontal bone, which is separated from the jugal. And the third in Dermoptera, the frontal doesn't form an arch like in Primates and P. lowii, but unlike these, the jugal doesn't form a complete arch.

We can find 3 different auditory region structures within Euarchontoglires. In P. lowii, the bulla is completed by an entotympanic-caudal process of the petrosal, very similar to Primates. In the other Scandentia, the bulla is completed by a ectotympanic process of the alisphenoid, like in Glires. And finally, in Dermoptera, the bulla is completed by an ectotympanic-entotympanic process of the rostral, but this condition is plesiomorphic within Eutheria.

So, what do you think /sci/? If this different structures represent true clade synapomorphies, this would mean Scandentia is polyphyletic, Primatomorpha is paraphyletic (and probably a synonym of Euarchontoglires) and Tupaiidae is the sister clade of Glires.

Basically this is how our maths final looks like
After you finish around half of the classes in Algebra and Calculus 1/2, you do this test consisting of 50% theory and 50% problems

If you do >50% of both the theory and problems your x/100 points are multiplied by 0.5 and carry half of total points + you are freed of doing those problems on the final exams

If you do <50% on one of those two, your x/100 are multiplied with 0.3 and carry less than a third of all points and on your final exam you do everything, the whole year

On the final exam, you again get theory and problems, with the same rules, your test is valid and your points will be accounted for only if you have >50% on both theory and problems, and than those x/100 points will be multiplied with either 0.5 or 0.7 depending on that last test

>But that's not all
Before the final exam you have to do the notorious test of basic knowledge which is
20mins
10 trick problems
Points are valued only if everything is correct
6/10 is pass

If you pass this you get to do the exam, if you fail you will still get the exam but it will be disregarded and not examined, you fail automatically

Me being the lazy idiot, I got only ~9 on all those 4 subjects making it quite difficult to pass the subject. So far I failed each one around 2 times, sometimes failing the test of basic knowledge, sometimes theory, sometimes problems, once passing everything but not having enough points for a passing mark

But not this week, 1 week 4 math exams, 4 clear passes

Oh yea, I didn't mention

If I didn't pass this now, I would have failed my year
Each year, more students here want to apply for Electrical Engineering because of increasing demand in that sector. When you apply, there are usually 4 times more applicants than actual room in collage, so only 1/4 of the best get to enlist

When you enlist 70% of students get free scholarship, and 30% have to pay(+ it's the most expensive government collage right now)
The thing is the collage was built for only ~350 students, but they overcrowd us and enlist ~700. That's why they make tests so increasingly hard, so that they could slash most of the students out of free scholarship and force them to pay. Usually, around 30% of those that got free scholarship lose it, half of those fail the entire year

I can finally sleep

At first, it was discovered that movement is relative. Then it was discovered that time is also relative.More recently, there are other things like moral and religious relativism. Does that mean there can be a thing such as Economic Relativism? I think it's very intuitive that growth, interest, inflation, profit and all that can only make sense when analyzed from certain perspectives, so where are the formulas? Why is there no "Relativist" school of Economics? How would that be like and when will it become a thing?

I'm posting this here because Economics is science & math related and /biz/ has become a board for professional shills.

I'd post this in /his/ since it's humanities, but let's not kid ourselves on the quality of that board.
I'm in sophomore year of a human services AS with plans on getting a BS in something related to substance abuse treatment.
However, I've always had a fascination with pic related and /r9k/ incel types - how they got the way they are, why they persist, and possible ways to counsel and treat them so they can be somewhat happy, reproductive members of society.
My question is, what kind of field would be good for this sort of thing? Adolescent counseling? Therapist?
Pic related.
