Murder as a victimless crime

SMBC often does great rationalism jokes, Zach Weiner is definitely our people (anyone know if he frequents Less Wrong?). Today's comic rephrases the old Torture-vs-Dust-Specks debate. I realize some people posit that death has infinite disutility and thus is inapplicable. Still, an example of the sort of problem one often encounters when trying to promote a shut-up-and-multiply rule in morality.

Does building a computer count as explaining something to a rock?

 

(If we still had open threads, I would have posted this there. As it is, I figure this is better than not saying anything.)

Advice request: Buying a car

1 Maelin 29 May 2011 07:33AM

So I'm looking at buying a car. At the moment I am using my parents' old car, however when I move out of home I will not be able to take it with me, and it also lacks some of the features I would like (cruise control in particular).

I'm looking at buying a small car, probably a hatchback. At the moment I have saved around AU$12,000. My parents are willing to lend me some amount, probably up to $5000, and I work for a bank which can give me a loan at a very favourable staff rate. I earn a bit over $325 per week at the moment and I have few living expenses beyond luxuries, that income is bolstered semifrequently when I can work extra shifts. At the beginning of 2013 I will be seeking a full time job as a high school teacher.

Looking at a few car websites (in particular carsales.com.au) it appears I can buy a fairly good second hand car for around $15,000, or a brand new car that seems quite good for around $24,000. This is a very rough guide to local prices.

I am aware that my decision process in this judgement is very fallible because I don't know much about buying cars, e.g. the potential pitfalls of a second hand one, and any other things I need to take into account.

Being as this is by far the most money I will ever have spent on a single thing and it is likely to last me for most of a decade at least, I am strongly motivated to make this decision rationally.

Does anybody have any advice they can give on how I can decide how much money to spend, or things I should consider when comparing potential cars?

A discussion of an applictation of Bayes' theorem to everyday life

9 AdeleneDawner 29 May 2011 06:04AM

[12:49:29 AM] Conversational Partner: actually, even if the praise is honest, it makes me uncomfortable if it seems excessive.  that is, repeated too often, or made a big deal about.

[12:49:58 AM] Adelene Dawner: 'Seems excessive' can actually be a cue for 'is insincere'.

[12:50:05 AM] Conversational Partner: oh

[12:50:25 AM] Adelene Dawner: That kind of praise tends to parse to me as someone trying to push my buttons.

[12:51:53 AM | Edited 12:52:09 AM] Conversational Partner: is it at least theoretically possible that the praise is honest, and the other person just happens to think that the thing is more praiseworthy than I do?  or if the other person has a different opinion than I do about how much praise is appropriate in general?

[12:52:59 AM] Adelene Dawner: Of course.

[12:53:13 AM] Adelene Dawner: This is a situation where looking at Bayes' theorem is useful.

Torture Simulated with Flipbooks

9 Amanojack 26 May 2011 01:00AM

What if the brain of the person you most care about were scanned and the entirety of that person's mind and utility function at this moment were printed out on paper, and then several more "clock ticks" of their mind as its states changed exactly as they would if the person were being horribly tortured were printed out as well, into a gigantic book? And then the book were flipped through, over and over again. Fl-l-l-l-liiiiip! Fl-l-l-l-liiiiip!

Would this count as simulated torture? If so, would you care about stopping it, or is it different from computer-simulated torture?

List of literally false statements in the Bible

-13 Academian 20 May 2011 08:10AM

Jehova's Witnesses aim to interpret the Bible literally, which is in some sense admirable because that is the only way it can serve much to constrain one's anticipations about reality.  By contrast, if one aims to interpret a religious text only "metaphorically", then there are so many possible meanings that it does essentially nothing to constrain one's anticipations.

For example, when one accepts the best scientific knowledge about the origin of Earth, one believes that it was not in fact created in 6 days, and that the literal meaning of the English Bible is false in this case.  Christians who accept the true age of Earth are not usually bothered by this, and resort to a "metaphorical" interpretation wherein "days" are metaphors for longer periods.

But if you only believe that each statement in the Bible has some metaphorical interpretation which is true, it doesn't tell you much about the world at all.  The Bible asserts that God exists... but since we're only taking things metaphorically now, maybe God doesn't actually literally exist.  Maybe He's pretend.  Maybe there in fact is no God, but there is a rainforest, and God is a metaphor for the rainforest.  Or for the sun.  Who knows.  Since there is no way to tell which metaphor is the right one, believing that the Bible is "metaphorically true" basically tells you nothing.

Jehova's Witnesses seem to understand this, so they're not going there.  They're sticking to the literal Word of the Lord.  Which makes me interested:

What verses of the Bible can we cite that are false in their literal interpretation, according to accepted scientific or well-founded historical knowledge?

Thanks to anyone who contributes!

Coercion is far

-6 saliency 16 May 2011 12:37AM

I was in the subway about a month ago when saw an advert for a new show The Bourgeoisie.  While waiting for my train I thought about the families patriarch and the control he probably exerted over family members.  I imagined the cliché of the daughter forced into a marriage for political advantage.  I thought about the sacrifice for the greater good of the family that she would be coerced into making and thought how it is easier to force others to sacrifice then to sacrifice yourself.  I thought that coercion may be one of the mechanisms that have enabled humans to engage and execute long term plans.  If the immediate short-term costs are what most often repress long-term action then those not saddled with the short-term costs of their long-term actions will be prone to engage in more long-term action.  Coercion is far.

Motivation quotes

3 zntneo 11 May 2011 05:08PM

I have been looking for rational motivation quotes because most quotes I hear don't seem to be. As an example i see in sports "pain is weakness leaving the body" this seems irrational and maybe harmful. 

Norms survey (dead)

0 Cayenne 10 May 2011 11:01AM

Edit - Barring a major surprise, this post should be regarded as a worthless artifact of my impulse to do things instead of talking about them.  I apologize for any time wasted on this, and would recommend ignoring it unless it is for historical purposes.  I'll just stick to things I'm less bad at from now on.

 

This article will be edited as people post and discuss.  

I believe that we need to have a clear, concise statement about the beliefs, practices, and taboos that it is rational to hold, and that we already hold as a group.  To be clear, this is not an attempt to make new norms, but an attempt to codify the ones that we already hold and to get a rough estimate of the popularity/importance of each.

Core Rational - skills, meta-beliefs, and habits that enhance personal rationality

Social Rational - norms that enhance working in groups rationally

LessWrong Norms - norms for dealing with Less Wrong specifically

Common Knowledge - basic, useful beliefs to build on


Please post one phrase at a time and then give your reasoning under it.  Once any idea has a common consensus, I'll add it to this article in the appropriate list.  

Edited - Removed the word 'should' as someone has suggested a better phrasing.  Edited again - category change, remove extra now-useless examples.
