For me, antidepressant medication makes a huge difference in how much I can tolerate setbacks, demands, interruptions, and other annoying bullshit.

This kind of tolerance is not always a good thing, however, as this anecdote shows:

The punch line comes when he asks one of his patients how her antidepressant medication is working. “It’s working great,” she says. “I feel so much better. But I’m still married to the same alcoholic son of a bitch. It’s just now he’s tolerable.”

This seems like it would really suck if you're trying to learn something that doesn't have a simpler model than the thing itself. English spelling can be like this: you either know how to spell "through" and "separate" or you don't. I've always found foreign language vocabulary to be the hardest thing for me to learn in school. It's terribly incompressible. Knowing that "red" is "rojo" and that "blue" is "azul" doesn't help you at all when trying to remember that "green" is "verde". I wasn't terrible at it, but my usual trick of "remembering things by actually understanding what's going on, so I can compensate for imperfect memorization" was completely useless.

It's the grid-level storage problem. Solar panels don't produce much energy at night, wind doesn't blow all the time, etc., so you need to produce extra energy and store it for when production is less than demand.

Shipping small packages from China to the US via the USPS has been subsidized - the price of mailing a Beanie Baby from Beijing to New York has been lower than the price charged to mail that same Beanie Baby from Los Angeles to New York. One of the few things the Trump administration did right was renegotiate the international postal system treaties so that China doesn't get "developing nation" subsidies any more.

If the actuarial statistics I've read are accurate, about 1 in 1000 18 year old men in the US die before their 19th birthday. If the chance of dying each year stayed perfectly flat, life expectancy would be about 1000 years...

Comment by CronoDAS on Anti-Aging: State of the Art · 2021-01-20T00:51:49.750Z · LW · GW

Science fiction author and physicist David Brin has pointed out a theoretical reason why we might expect anti-aging therapies that work in mice to fail in humans: the human lifespan is already a ridiculous outlier. Life spans vary with size, metabolism, and other factors, but one thing tends to hold constant: most mammals have a lifetime of about one billion heartbeats. Humans get a whopping 2.5 times that. An intervention would have to more than double a mouse's lifespan just to catch up with whatever it is that evolution has already done to humans - if there are any simple mechanisms that can cause a mammal's body to increase its lifespan, humans are probably already pushing them to their limits.

Pick 2^N potential targets. Send half of them a prediction that a stock will go up and the other half a prediction will go down. Eliminate the people who got a wrong prediction, and then do this again and again. Eventually you'll end up with one guy who's convinced you're never wrong, so charge him an arm and a leg for investment advice.

I have since lost some faith in the Magic Online Event Ticket. I do not have any more faith in Bitcoin than I did eight years ago. Furthermore, I'm fairly confident that Bitcoin is of net negative value to the world - a huge amount of energy is devoted to computing otherwise useless hashes so hackers can collect ransoms and some people can try to take money from greater fools.

Comment by CronoDAS on Introduction To The Infra-Bayesianism Sequence · 2020-09-02T19:09:39.976Z · LW · GW

Why are you minmaxing over expected values of policies, instead of over outcomes? Isn't the worst case for the "tails only" policy "I'm in COPY and the coin is heads", not "'I'm in COPY"?

Basically I don't understand why "past me, who is screaming at me from the sidelines that it matters whether I pick tails or not" once I see that the coin comes up heads is actually correct and the "me" who's indifferent is wrong; one man's modus ponens is another man's modus tollens.

Here's another example that makes my intuition go "ouch" - suppose that choosing heads in REVERSE HEADS when the coin is heads gives 0.1 utility. Then the "match the coin" policy has an expected value in REVERSE HEADS of 0.3 instead of 0.25 and the minmax rule you picked still tells you to "always pick tails", but conditioning on heads, "pick heads if you see heads" gives you 0.1 utility or 1 utility, while "always pick tails" gives you 1 utility or 0 utility, so isn't "pick heads" a better strategy?

Comment by CronoDAS on Introduction To The Infra-Bayesianism Sequence · 2020-09-01T00:39:35.073Z · LW · GW

Maybe I'm understanding this wrong... but isn't there another kind of dynamic inconsistency here?

Suppose you walk into an empty room. Then you're told you're in either WORLD A, which gives reward 1 for choosing heads and reward 0 for choosing tails, or WORLD B, which gives reward 0 for choosing heads and reward 1 for choosing tails. You have Knightian uncertainty between the worlds, so you minmax and end up indifferent between them; you arbitrarily choose heads.

Then you hear a voice:

"Actually, I flipped a fair coin that came up heads. If it had instead come up tails, in WORLD A you would have gotten reward 1 for choosing tails and reward 0 for saying heads, but in WORLD B you would have gotten 0.5 reward no matter what. (And my monologue would have changed appropriately.)"

Should you reconsider your decision to choose heads? What you learned doesn't actually change the decision you're faced with, does it?

Sports bookies deal with "investors" that have net biases - lots of people will, for example, bet on the home team because they're fans. I also have it on pretty good authority that people drastically underestimate the variance in soccer matches between closely matched teams; when the World Cup comes around, a simple strategy of "bet on the underdog in every match" makes money.

Calculus itself isn't inherently more difficult to learn that earlier math, but it is where many math students hit a wall because it has a lot of prerequisites; if you were a mediocre student in algebra and trigonometry, there is a good chance that you will have trouble with calculus because you never completely mastered other skills that you have to use over and over again when doing calculus.

Possibly Antonie van Leeuwenhoek's study of microorganisms; he made microscopes that were much better than anyone else's at the time, and he kept his methods secret and they weren't properly reverse engineered until the 1950s. (Conventional lens making techniques did catch up, and people like Robert Hooke had been investigating biology on micro scales, but he was probably a generation or so ahead of everyone else.)

Comment by CronoDAS on The Politics of Age (the Young vs. the Old) · 2019-03-24T16:25:09.300Z · LW · GW

If there's a minimum voting age, I think there should also be a maximum voting age. Sufficiently old people suffer from cognitive and physical decline, frequently to the point of dementia, and can be as vulnerable to manipulation or coercion by their caretakers as children are to their parents. It seems entirely reasonable to me that people over 80 should not be allowed to vote.

B) I don't want to be doing x.

I got permission from the math department at Rutgers to skip the proof-writing class... I think I must have picked up the skill elsewhere, because I didn't feel like I had any trouble with the proof-based linear algebra and real analysis classes that would normally require the proof writing class as a prerequisite.

(The most likely places I learned the skill was from non-textbook books on mathematics and from the philosophy department's classes on formal logic that I used to cheat on my degree's humanities requirement.)
