care to explain?

Sure. I was replying to a comment in which worker ownership and worker leverage were being equated with "the gulag", a collective term for the Soviet Union prison/labor camp system. To illustrate that large-scale freedom, ownership, and autonomy do not result in labor camps, I provided Mondragon as a productive counter-example. Mondragon is a federation of worker-owned cooperatives that netted €593 million on €11 bil…

That makes a lot more sense with the explanation thanks.

> Does cocaine temporarily boost intelligence? I thought it boosted the feeling of being intelligent. For people who lack confidence or an ego, this may very well be the same thing. Just the urge to prove myself got me far in life. Sometimes I clearly struggle more than others, especially when surrounded by extremely smart people at university, but at the end of the day I've gotten much further than those who capitul…

I've long believed most people can learn most things if they're willing (and able) to make the effort and have the right resources available to them. When I left university, I started a job writing Android apps that required high-performance and low-level stuff, at the start I couldn't imagine it ever being "easy", I struggled at first to understand it all, and often wondered if I'd ever be good at it; but over time…

While this is true for many people, and most of the people you'd interact with on HN or, possibly in your daily life, it is not true for all people.

High IQ correlations with life outcomes are usually pretty weak, but low IQ correlations with undesirable outcomes are very strong - I think smart people systematically underestimate how limiting it is to be not-smart.

Side topic, but dropping coffee was the best thing I ever did. I used to drink only one cup a day, rarely two, for many years - but turns out when I stopped (for reasons unrelated) my anxiety unexpectedly 80% went away after a week or so without any other changes in my lifestyle. It was a big difference and I feel now very different than what I used to. I wake up much better rested too (much easier to get out of bed)…

I've had a very similar experience. If i drink coffee daily, it bumps my anxiety significantly after a few days or a week. If i rarely have it, it's usually fine. But if I let myself have it, it's too easy to trend towards daily again.

I drank coffee for years and don't think it had an impact, but at some point, I noticed it and the impact was very real when not drinking it.

People do joke about being dangerous without their morning coffee, but I have yet to see a coffee addict breaking into vehicles to score their morning fix. Also I have never had to worry someone is going to mug my loved ones to get some quick cash for a double-double. And have you ever heard of someone who skips important appointments because they stayed out getting high on caffeine instead Pretending caffeine is as…

This is what the drug war has done to our minds. People would absolutely be burglarizing homes to feed their caffeine habit if caffeine wasn't dirt cheap due to the free market. If it were legal to produce meth your local meth-head would not be raiding your house for copper because it would be cheap enough that his minimum wage job could support his habit.' And frankly I've showed up to important events absolutely fu…

>People would absolutely be burglarizing homes to feed their caffeine habit if caffeine wasn't dirt cheap due to the free market.

I'm about as caffeinated as most anyone else I know, and I would not. There are times where just putting on a pot of coffee is too much work for me to make my daily fix and I lazily skip it for the day.

I do get withdrawal headaches and probably behave a bit differently, but even then sometimes I don't make the effort to get it. I've been at conference and hotels where the only options were so badly made I skipped it for days and just took the headache.

i think you are bitting the dust of getting used to the taste of a drug, just like people who drink wine, beer etc. these are literally toxic & you get a natural avoidance response the 1° time you try, with very rare cases of acceptance without repulse

I never understood the acquired taste thing. If I don’t like the taste the first time I try something then there won’t be a second time. Why acquire a taste for something you didn’t originally like?

I really disliked beer until I was about 25 years old. I kept occasionally trying it, maybe because my girlfriend liked beer, and one day, to my surprise, found a particular beer I really liked. Trying new craft beers is now a bit of a passion, and have had over 250 different beers (I avoid buying repeats [unless extremely good] or a multipack)

> caffeine addicts are standing in line at Starbucks Have you considered that those people queuing outside Starbucks might be drinking coffee because they enjoy the whole experience? Caffeine pills are an absurdity to me because I only drink coffee for the taste. Why suffer the unwanted effects of a drug without the enjoyment that it’s supposed to come with?

Are they ordering decaf?

It is my understanding that decaf coffee is typically made from poor quality beans, because consumers typically expect decaf to cost as much as regular coffee even though the decaffeination process means an additional cost.

For decades I only drank decaf and only in the past few years I have replaced my morning cup with regular coffee because it's so much easier (and cheaper!) to find good beans.

In other words, there are good reasons to consume caffeinated coffee besides an addiction to caffeine.

> Have you considered that those people queuing outside Starbucks might be drinking coffee because they enjoy the whole experience? Not the OP, but to respond to your question I think that Starbucks is actually hitting its customers with a triple-whammy of caffeine, sugar, and fat that most brains can't resist addiction to. Are you sure they actually enjoy Starbucks coffee and not its addictive components?

Not OP but I generally only order black coffee when I go to Starbucks, so yes.

I love my caffeine. But caffeine is an addictive, highly profitable substance. So advertising it and trying to promote it as somehow having real health benefits is widespread. I would not be surprised if routine consumption of caffeine was at least mildly detrimental to health. I think some drugs have managed to gain a special place in our society . Advertising and lobbying warps our perception of these drugs. I even…

> highly profitable substance Yes and no. I've been a fan of caffeine pills for years. They are very cheap, readily available (portable), and most importantly to me offer completely consistent dosing. With caffeine pills I'm able to ensure I stay below the FDA recommended maximum daily intake of 400 mg (worst case). Another fun bonus - when a physician asks you what your caffeine intake is and you respond in milligra…

most people at starbucks are addicted to sugar and not caffeine
