Well, yes, adding noise increases the fractal dimension of a signal. "Shannon entropy" is noise. "Lempel-Ziv complexity" is "how long is the zip file".

Does listening to white noise increase the fractal dimension the same way as drugs?

No.

I'll take the bait. A drug being regulated by narcotics regulation does not mean that its use has to be completely forbidden. Just because Average Joe is not allowed to do something does not mean that there might not be professionals who are. Opiates for example are both regulated and used for pain treatment. Any study with human participants has to go through an ethics review and the participants have to be both inf…

You have to understand that because animals borrowed cell signaling form plants that most transmitter blockers and analogues can be found plant cell signal chemicals Or to put in broad terms our brains are powered by degrees of getting high. Its more of the degree and method that produces bad social results

The similarities between very different species are absolutely mind-blowing indeed. Anesthesia works on plants for example! Jellyfish have to sleep, despite having no brain at all. They even suffer from disorientation when being sleep-deprived (afaik researchers frequently poked or otherwise disturbed them in their tank during their normal sleep-phase. On the "next day" they showed signs of sleep deprivation).

There is lots of potential benefits that far outweigh any downsides,so it's worth investigating. They were made illegal for political reasons rather than for scientific or evidence based reasons

Sources for benefits (plural) vs. downsides? Source for politically-motivated criminalization?

Not lsd but the reason behind the banning of cannabis and heroin is a pretty well known story https://www.unharm.org/the-racist-truth-behind-the-war-on-dr...

They were criminalised to criminalise part of society. Lsd was similar - the govt was worried about losing control of people and their desires.

Lsd has never been an interest of mine, but I am aware many people find the experiences they have truly profound.

there was some excellent work in curing alcoholism that used Lsd and proved very successful prior to it being banned; BBC News - LSD 'helps alcoholics to give up drinking' http://www.bbc.co.uk/news/health-17297714

Anecdata: I once took LSD and went on a bad trip.

I "discovered" that everything in the universe is fractal: space, time and causality. Every microsecond of existence contains within itself the whole existence of the universe and at the same time each one of those 'temporal universes' contains other temporal universes, every micrometer contains the whole space, and every moment there are millions of decisions that take us to the next 'frame', but the other decisions still exist and have their own decision trees.

Also, we're all the same person or being.

Weird day.

That sounds like a profound experience, would you say these insights had any lasting impact on your life? And, if may ask, in what way was it a bad trip? I once took LSD and was hoping for that level of experience, but only got nice visual sfx and some bad emotions later on.

Lots (hundreds? thousands? a large cross section of the population of every music music festival on the planet for the last 50 years) of human beings report them encouraging a good time with increased enjoyment, openness, creativity, ability to do things, and they where praised by the creators of AA to be helpful in the treatment of alcholism. Very few of the doctors, nurses, lorry drivers, support workers, shop keepers, crafters, farmers, scientists who attend these events and lie about their participation go on to develop serious social or medical problems or they wouldn't have the money to go back year on year for more illegal fun. Unfortunately the majority of these positive experiences are not recorded by government backed science, since reporting LSD use to the government results in the loss of jobs, driving privileges, children and ultimately homes and freedom. Users complained about the war, lsd was banned (- over simplification for brevity.). Laughter has no accepted medical use and trying to prove otherwise is a crime

Consider that you're remarking on his takeaway here. The "insights". The conceptual end-product of all that strange-seeing.

But it's the strange-seeing that's the real feast.

I would say it has opened a door to different way of seeing reality, and I can open that door whenever I want, but I don't think it has changed any of the practical decisions I've made.

It was a bad trip because the fractal nature of time implies that your life repeats itself infinitely many times (probably with the exact same details). You can never rest, it's all an infinite loop, and that idea made me extremely distressed, like this fractal nature was some sort of punishment or permanent purgatory.

Why is it even legal to conduct LSD experiments? There was some animal testing post earlier, but giving people illegal consciousness altering drugs seems so much worse.

Out of curiosity, which part bothers you?

1. That the drugs are illegal

2. That the drugs alter consciousness

What’s your stance on cannabis?
