I'll do 10. Agreed with satt that having multiple raters for each prediction would be helpful. I previously read your previous post with the randomly selected predictions, which hopefully isn't disqualifying.

Cheers! Fine as long as you try and ignore them :-)

Have you spent $28,000 on nonessentials for yourself over the course of your life? Most people can easily hit that amount by having a nicer car and house/apartment than they "need". If so then by revealed preference, you value those nonessentials over 28 statistical lives; do you also value them over a shot at immortality?

For anyone in the vicinity, I highly recommend checking it out. Patrick and Jon and the non-LW people I met were very friendly, and I'm looking forward to studying Jaynes.

The hackerspace has quite an impressive collection of hardware, from a RepRap and MakerBot to the huge CNC mill and lathe, and even the beginnings of a biology lab. The current limit of my mechanical skills is assembling Lego Mindstorms, so it's a great learning opportunity.

I'll plan on showing up. Should be interesting, I've never been to a hackerspace before.

Thanks for coming out.

Knowing virtually nothing about the geography of Sweden, I'll guess 10,000 feet.

I was skeptical as well, but Googling for "immune to exercise" produced this: http://www.newscientist.com/article/dn6735-some-people-are-immune-to-exercise.html. It seems like an area that could really use further research; if the universally-dispensed advice is ineffective for nearly half the population, that's a huge problem.

Yes, but that shows that Eliezer probably misremembered what the 40% referred to. In that study, "40%" refers not to how many didn't benefit, but rather to the maximal benefit on a particular measure of fitness received by any of the participants:

For example, the team found that training improved maximum oxygen consumption, a measure of a person’s ability to perform work, by 17% on average. But the most trainable volunteers gained over 40%, and the least trainable showed no improvement at all. Similar patterns were seen with cardiac output, blo

The first observation was particularly interesting: "1. Sociopaths typically don't smalltalk about themselves as much as normal people do. They will direct the conversation back to the new acquaintance as much as they can." This seems like the perfectly rational thing to do (in most cases)

It's also what all the "winning friends and influencing people" advice tells you to do.

75% probability of being mainstream, or at least not unusual, by 2020. It seems like the obvious solution: phone screens are too small, laptops and even tablets are too inconvenient to carry around constantly. And I'd go 50/30/20 on the first mass market product being based on Android/Apple/other. (With Android, anybody can build it without asking for permission).

The argument for Apple is that a killer-quality device in this category would require serious UI support from the OS, possibly new interactions (eye tracking for example).

I'd guess that any delay that gives the other party a chance to back out would be sufficient. When determining the expected utility of each offer, there should be a term for the probability of the deal actually going through. That's very close to 1 when you take the $100 now and less if you have to wait a day for $120, which might tip the balance toward the $100. But the probabilities are nearly identical for 30 and 31 days, so $120 is the better choice there.

Good point. It might be interesting to try to find a money delta (ie, $100 vs. $200 or whatever) where someone would take the earlier one at 30 vs. 31 days, but the larger one at 90 vs. 91 days. But I'm not sure how much that would prove.

The concept that "I was acting rationally" isn't an excuse for predictably failing to maximize utility. I used to be a two-boxer on Newcomb's Problem; more practically, I believed that certain social situations were inherently biased against rational people.

I must not be a very good rationalist, because I find it blindingly obvious that if I believe one of two choices will have a better outcome, I should make that choice. :)
  1. 0.2 (I recall reading that white is the most common color, and I do see a bunch).
  2. 0.2 (p(10 year old Ford)=~0.001) (p(dent on rear right|10 year old Ford)=~0.01) =~ 2e-6, or 1 in 500,000.

Re #7, its past use as a discussion tool makes it more likely that people will create/simulate such situations as a joke in the future. The probability of "actually happening" thus seems far too low.
1sixes_and_sevens
You have a very high opinion of proof readers :-)

"Too big to fail" banks: they profit when their gambles pay off, we bail them out when they don't. Also arguably telecommunications carriers that have quasi-natural quasi-monopolies.

1James_K
I'd go along with both of those examples (though the US has a history of corporate bailouts that extends far beyond current events). Also rent control (it has significant perverse effects on rental markets and often hurts the poor). That's not to say other countries don't have their problems, I don't think the US is a uniquely bad policy maker, but there is something about the way the US government makes policy that seems to want to have its cake and eat it too. When they try that it usually doesn't end well.

The whole "happiness limited by shyness/social awkwardness which results in no dates" stereotype does not apply to many people here.

It does to at least one.

I'm all for this. I've gotten sort of lucky by wandering into a path where I can be professionally and financially successful without needing social skills beyond not saying blatantly inappropriate things. But developing those skills would provide many more options, and give me a much better shot at making an actual impact on the world.

And yes, being involuntarily single for years is neither enjoyable nor conducive to productivity.

I came here to post almost exactly that. Additionally, it inspired me to make another donation to the SENS Foundation.

I reject that entirely," said Dirk, sharply. "The impossible often has a kind of integrity to it which the merely improbable lacks. How often have you been presented with an apparently rational explanation of something which works in all respects other than one, which is just that it is hopelessly improbable? Your instinct is to say, `Yes, but he or she simply wouldn't do that.'"

Douglas Adams

After shutting up and multiplying, I agree those arguments are valid. This presentation by Anna Salamon is also instructive.

I'm uncertain as to whether funding for SIAI or anti-aging research provides the best marginal utility. Both would have a gigantic positive impact if successful; SIAI's would be larger but in my estimation anti-aging has a better chance of success. The matching donations tip the balance to SIAI today, so $900 more is on the way.

I do believe the political argument with number of donors may apply to SENS and MF, so I'm making smaller ... (read more)

$100 to general fund. I've recently received some unexpected cash and am looking at ways to increase humanity's expected utility. I'll be donating to SENS and the Methuselah Foundation as well. Where else should I be looking?

The Future of Humanity Institute.

Eliezer and SteveLandsburg agree: don't diversify your (altruistic) giving.

That was rather interesting. I got a 137 but beyond the first few questions I wasn't sure of any of them. Usually the best I could do was identify a possible sub-pattern, narrow down the options based on that, and make an educated guess. I think I did better on the ones with varying numbers of dots and lines compared to the ones with just the shapes moving and morphing.

Presumably if somebody took that test repeatedly (or possibly once if they're smarter than me), they'd figure out the class of algorithms being used and it would lose most of its value for determining immediate mental performance.

1Jonii
Actually, nope, I think that's exactly why it would make such an excellent benchmark for mental performance. The algorithms are surprisingly simple and after learning those, it's all about applying that limited library to the problem. Fast. If your performance is above average, you can do this a lot easier and faster and with less errors compared to a situation where you're not doing as well.

I tried it on two women at work and they both went for the million, one with no hesitation and the other after maybe 10 seconds. Although they both have some background in finance and are probably 1 to 2 standard deviations above average IQ.

2Eliezer Yudkowsky
That's not very surprising. You could see if they passed all three questions on the reflection test.

My fiance (who has a more advanced degree than I) thought I was trying to trick her and made me restate the problem several times.

That sort of attitude (among my opponents) is very helpful to my poker bankroll. You're giving up $60 for $50 of expected value. Even given your risk-seeking preference, surely you can find a better gamble. Putting it on a single number in roulette would be a better deal.
