People with severe depression probably have things they don't get around to here. No phone or internet means no family or friends, but I guess if you are planning to feed them 10g of shrooms and dump them back into a hunter gatherer lifestyle in South America you won't want them contacting anybody.

I personally would very much like to use my phone after somebody fed me TEN GRAMS of shrooms. I strongly feel that I would want to do them on the plane, and not in a remote village where I don't even speak the language, and I've got to occupy myself in the darkness with strangers who are going to make me stagger into the jungle and fish, or farm, or hunt. Something I was not severely depressed about would be my very low parasite load, or the lack of arthropods in close proximity. In fact, there are virtually none here.
Somewhere in South America there are very large spiders. We don't have them here. I would certainly not be depressed about this. In fact, I am jubilant and appreciative of my good fortune.

In fact, were I to have this condition, it would stem from an imbalance in my head. Because of it I would become depressed. This would be different than me not being "tuned" to my lifestyle, it's not clinical depression if I just need to paint my walls orange or just stop being such a mopey downer, it's a real drag, pitter patter, let's get at er! WEW! PROBLEM SOLVED!

It's like going bald, or having asthma, or being washed away by a tsunami while you are on a date. Sometimes things happen, which are not ideal and also not because of any defect or sin on your part. Sometimes things just happen, sometimes they happen to you.

For example, the poor person who's mind you reset with TEN GRAMS of shrooms and fired off thousands of miles from home and back in time thousands of years to do backbreaking manual labor among strangers. Seems unusually coercive, no? Punitive. Would you do that to your dog? A dog? For being sad too long?

Depressed is not stupid, after the monumental shroom trip, you'd have to force them to stay there, surely? This is probably the part where the ethics board might ask more questions, I reckon. We agree on that at least. Anyway, what if they in fact are not shamming and succumb to despair? Or simply tip the canoe or whatever over learning how to fish? TEN DAMN GRAMS of shrooms is going to make skills acquisition difficult, for quite some time after they eat them.

Socialization might be a lot to ask, do we share a language? What's the purpose of this anyway? Shouldn't this PURPOSE be something defined by me? Lack of agency was not a problem I had before, why is it part of your experiment? I mean, you don't even give me a choice, can't I volunteer or something? My friends probably are not sick, can I socialize with them? Instead of the strangers? In the village? How about you send me to work in Milan? Ok, Wales? Scotland? Missis... hmm. Scotland?

I mean really, you think phone and internet need to go, but instead want to force group interactions with strangers instead?

By the way, about your "personal opinion." If you know a whole bunch of people with ranges of issues, how did you achieve the deep insight into las depresionistas? Or are you saying that slacking is the root cause of mental illness? Force them into paleolithic lifestyle and they'll snap out of it? Would you say you've read 10 books on the subject? How many more than 10? Lots? I'm just trying to properly value your opinion here. How's your results?

Finally, I have to say that your experiment kind of seems similar to pray away the gay camp or whatever name was used for it. Isolation, coercion, duress and reconditioning. Plus TEN GRAMS OF SHROOMS.

Whole thing seems a bit sus, frankly.
