Does that actually work better than just setting a higher bar for significance? My gut says that data is data and chopping it up cleverly can't work magic.

Cross validation is actually hugely useful for predictive models. For a simple correlation like this, it's less of a big deal. But if you are fitting a local linearly weighted regression line for instance, chopping the data up is absolutely standard operating procedure.

My intuition is that chickens are less sentient, and that is sort of like thinking slower. Perhaps a year of a chicken's life is equivalent to a day of a human's. A day of a chicken's life adds less to the numerator than a day of a human's, but it also adds less to the denominator.

Maybe I'm way off base here, but it seems like average utilitarianism leads to disturbing possibility itself. That being 1 super happy person is considered a superior outcome to 1000000000000 pretty darn happy people. Please explain how, if at all, I'm misinterpreting average utilitarianism.

How much does a genius cost? MIRI seems intent on hiring a team of geniuses. I’m curious about what the payroll would look like. One of the conditions of Thiel’s donations was that no one employed by MIRI can make more than one-hundred thousand a year. Is this high enough? One of the reasons I ask is I just read a story about how Google pays an extremely talented programmer over 3 million dollars per year - doesn't MIRI also need extremely talented programmers? Do they expect the most talented to be more likely to accept a lower salary for a good cause?

Two notes: First, the term "genius" is difficult to define. Someone may be a "genius" at understanding the sociology of sub-Saharan African tribes, but this skill will obviously command a much lower market value compared to someone who is a "genius" as a chief executive officer of a large company. A more precise definition of genius will narrow the range of costs per year.

Second, and related to the first, MIRI is (to the extent of my knowledge) currently focusing on mathematics and formal logic research rather than programming. This makes recruiting a team of "geniuses" much cheaper. While skilled mathematicians can attract quite strong salaries, highly skilled programmers can demand significantly more. It seems the most common competing job for MIRI's researchers would be that of a mathematics professor (which have a median salary ~88,000$). Based on this, MIRI could likely hire high quality mathematicians while offering them relatively competitive salaries.

Writing a string of symbols, publishing it, and selling it more times than has been managed with all but 100 strings of symbols.

Give machine A one nickel and have it produce a random sequence of 499 characters. Have machine B write a random sequence of 500 characters. Code machine A to pay machine B one nickel for its "book" whenever it has a nickel. Code machine B to give a nickel to machine A for its book whenever it has a nickel. Wait perhaps a few days, and you will have two bestselling authors reminiscent of Zach Weiner's Macroeconomica http://www.smbc-comics.com/?id=2855

A study suggests that happiness is negatively affected by having children

It doesn't seem to. Following your link, the study suggests that working women in Texas weren't very happy when taking care of their kids.

That's an answer to a drastically different question.

Sorry, a more applicable study is behind a pay-wall. http://www.jstor.org/discover/10.2307/351391?uid=3739640&uid=2&uid=4&uid=3739256&sid=21103313626383 Summary: data from six surveys suggest negative correlation between having children and several measures of life satisfaction. Standard caveats that correlation doesn't imply causation, etc.

A study suggests that happiness is negatively affected by having children http://www.npr.org/2013/02/19/172373125/does-having-children-make-you-happier Note, there seem to be some issues with the methodology used in the study, but it also seems to be fairly well respected in academia.

Nitpick, the link in the first sentence reads "Definability of Truth in Probabilistic Locic" rather than logic.

I recommend trying loving-kindness meditation.

Could you elaborate? I'm relatively familiar with and practice mindfulness meditation, but I've never heard of loving-kindness meditation.

You say

I find myself happier when I act more kindly to others.

Yet you said earlier that

How can I get more enjoyment out of alleviating others suffering and giving others happiness?

Does this mean that you feel that you do enjoy it but not "enough" in some sense and you want to enjoy it even more?

Comment author: Dan_Weinand 11 December 2013 02:16:27AM *  3 points [-]

Correct, it is enjoyable but I wish to make it more so. Hence why I used "more".

Comment author: shminux 10 December 2013 08:47:17PM 0 points [-]

What is your reason for wanting to?

Comment author: Dan_Weinand 11 December 2013 12:39:31AM 1 point [-]

I find myself happier when I act more kindly to others. In addition, lowering suffering/increasing happiness are pretty close to terminal values for me.
