Heuristics for a good life

Posted on June 11, 2010 | 9 comments

I wondered what careers or the like help other people the most. Tyler reposted my question, adding:

Let’s assume pure marginalist act utilitarianism, namely that you choose a career and get moral credit only for the net change caused by your selection.  Furthermore, I’ll rule out “become a billionaire and give away all your money” or “cure cancer” by postulating that said person ends up at the 90th percentile of achievement in the specified field but no higher.

And answered:

What first comes to mind is “honest General Practitioner who has read Robin Hanson on medicine.”  If other countries are fair game, let’s send that GP to Africa.  No matter what the locale, you help some people live and good outcomes do not require remarkable expertise.  There is a shortage of GPs in many locales, so you make specialists more productive as well.  Public health and sanitation may save more lives than medicine, but the addition of a single public health worker may well have a smaller marginal impact, given the greater importance of upfront costs in that field.

I’m not convinced that the Hansonian educated GP would be much better than a materialism educated spiritual healer. Tyler’s commenters have a lot of suggestions for where big positives might be too – but all jobs have positives and many of them seem important, so how to compare? Unfortunately calculating the net costs and benefits of all the things one could do with oneself is notoriously impossible. So how about some heuristics for what types of jobs tend to be more socially beneficial?

Here some ideas, please extend and criticize:

  • Low displacement: if someone had to be hired, you only add the difference between your ability and the second best candidate (plus the second best candidate’s efforts to another job at random). The same goes for what you produce. Even if creating beautiful music doesn’t knock another musician out of business, people listen to your new song instead of older songs, which are not seemingly any worse.
  • Big gains to a marginal person being better: careers that fail the above can still rate highly if this is so. This is a hard route because if candidate quality matters more there will generally be stronger selection so you will be more average for who they let in. Your best bet here might be in something important to you which usually attracts people with poor abilities.
  • Goal discretion: one way a displacing person can make a relatively big difference is to have a better purpose than the person they displace in a position where that matters. This is more likely in jobs that aren’t meant to be altruistic. e.g. if you head an NGO for delivering fresh water to poor households, you only add to the cause to the extent that you are better at it than the alternative guy. If you are an academic with some choice in research topics and no imperative to be altruistic, you can add a person’s worth of effort to an important topic at the expense of an unimportant topic without having to be any better at researching. Similar for shop owners and heads of state.
  • Profits: if you are making huge profits, it’s probably good.
  • Positive externalities: same.
  • Ongoing effects: usually a kind of positive externality. Nice cake lasts minutes whereas nice ideas last a long time (though someone else would have thought of them eventually).
  • Negative externalities
  • Fueling status races or other zero sum games: arguably things people buy to look better than other people do not cause any overall benefit, so you shouldn’t read too much into the profitability of selling such things. Similar for weapons in at least some situations. Same for selling any other negative externalizing capabilities.
  • Speeding trends: culturesome things tend to cycle through new variants continually. Contributing a song, movie, or meme variant for a current trend certainly makes a lot of people like you (briefly). But it’s not clear what people value here: each new item while it is new, or being up to date with the current trends in general. If the former you are doing them a service by adding your bit of culture, if the latter you are just making it more expensive for them to keep up.
  • Effects on galaxy colonization chances and speed: this matters so much you can ignore all the other things.

What jobs do well on most of these things?

Advertise while honoring the dead

Posted on January 4, 2010 | 16 comments

Roadside suggestions not to kill yourself driving seem to be getting more humorous around here, which suggests that someone is trying to improve them. The best advertisements for careful driving I’ve seen are the little white stick crosses tied to trees and telegraph poles with withered flowers and photographs. I doubt I’m alone in finding the death of a real person smashed into a telegraph pole on my usual route more of a prompt to be careful than an actor looking stern at me or a pun (‘slowing down won’t kill you’). Plus nothing makes an activity feel safe like a gargantuan authority calmly informing me of the risks of it. If the government’s advertising something, everyone knows about it, and if there’s no panic or banning, it’s probably safe. A bedraggled, unprepared memorial is a reminder that ‘they’ aren’t really protecting me.

But how could a road authority use these? They could either increase the number or the visibility of them. The usual methods of increasing the number defeat the purpose, and inventing fatal crashes might make people cross. Making memorials more visible is hard, because they are put up by families, besides which the home-made look is valuable, so billboard versions wouldn’t do so well. One solution is just to give bereaved families a bit of the money they usually use on a billboard to construct a temporary memorial of their choice at the site. That way more people would do it, and they could afford more extravagant decoration, so enhancing visibility.

Repeated thought

Posted on January 5, 2009 | 3 comments

Eliezer Yudkowsky of OB suggests thinking and doing entirely new things for a day: 

Don’t read any book you’ve read before.  Don’t read any author you’ve read before.  Don’t visit any website you’ve visited before.  Don’t play any game you’ve played before.  Don’t listen to familiar music that you already know you’ll like.  If you go on a walk, walk along a new path even if you have to drive to a different part of the city for your walk.  Don’t go to any restaurant you’ve been to before, order a dish that you haven’t had before.  Talk to new people (even if you have to find them in an IRC channel) about something you don’t spend much time discussing.
And most of all, if you become aware of yourself musing on any thought you’ve thunk before, then muse on something else. Rehearse no old grievances, replay no old fantasies.
The comments and its reposting to MR suggests that this is popular advice. 
It’s interesting that, despite the warm reception, this idea needs pointing out, and trying for one experimental day. 
Having habits for things like brushing teeth is useful – the more automatic uninteresting or unenjoyable experiences are, the more time and thought can be devoted to other things. Habits for places to go could be argued for – if you love an experience, why change it? 
But why should we want to repeat thoughts a lot? Seems we say we don’t. So, why do we do it? Do we do it? If we can stop when Eliezer suggests it, why don’t we notice and stop on our own? Is it that habits are unconscious; a state that doesn’t lend itself to noticing things? Has the usefulness of other habits made us so habitual that our thoughts are caught up in it? 
What can we do about it?
As a side note, perhaps the quantity of unconscious habit in a life is related to the way time speeds up as you age.

Don’t change your mind, just change your brain

Posted on May 22, 2008 | Leave a comment

The best way to dull hearts and win minds is with a scalpel.

Give up your outdated faith in the pen over the sword! With medical training and a sufficiently sharp but manoeuvrable object of your choice, you can change anyone’s mind on the most contentious of moral questions. All you need to make someone utilitarian is a nick to the Ventromedial Pre­frontal Cortex (VMPC), a part of the brain related to emotion.

When pondering whether you should kill an innocent child to save twenty strangers, eat your pets when they die, or approve of infertile siblings making love in private if they like, utilitar­ians are the people who say “do whatever, so long as the outcome maximises overall happiness.” Others think outcomes aren’t everything; some actions are just wrong. According to research, people with VMPC damage are far more likely to make utilitar­ian choices.

It turns out most people have conflicting urges: to act for the greater good or to obey rules they feel strongly about. This is the result of our brains being composed of interacting parts with different functions. The VMPC processes emotion, so in normal people it’s thought to compete with the parts of the brain that engage in moral rea­soning and see the greatest good for the greatest number as ideal. If the VMPC is damaged, the ra­tional, calculating sections are left unimpeded to dispassionate­ly assess the most compassionate course of action.

This presents practical oppor­tunities. We can never bring the world in line with our moral ide­als while we all have conflicting ones. The best way to get us all on the same moral page is to make everyone utilitarian. It is surely easier to sever the touchy feely moral centres of people’s brains than to teach them the value of utilitarianism. Also it will be for the common good; once we are all utilitarian we will act with everyone’s net benefit more in mind. Partial lo­botomies for the moralistic are probably much cheaper than policing all the behaviours such people tend to disapprove of.

You may think this still doesn’t make it a good thing. The real beauty is that after the procedure you would be fine with it. If we went the other way, everyone would end up saying ‘you shouldn’t alter other people’s brains, even if it does solve the world’s problems. It’s naughty and unnatural. Hmph.’

Unfortunately, VMPC dam­age also seems to dampen social emotions such as guilt and com­passion. The surgery makes utili­tarian reasoning easier, but so too complete immorality, mean­ing it might not be the answer for everyone just yet.

Some think the most impor­tant implications of the research are actually those for moral phi­losophy. The researchers suggest it shows humans are unfit to make utilitarian judgements. You don’t need to be a brain surgeon to figure that out though. Count the number of dollars you spend on unnecessary amusements each year in full knowledge peo­ple starving due to poverty.

In the past we could tell moral questions were prompting action in emotional parts of the brain, but it wasn’t clear whether the activity was influencing the deci­sion or just the result of it. If the latter, VMPC damage shouldn’t have changed actions. It does – so while non-utilitarianism is a fine theoretical position, it is seemingly practiced for egoistic reasons.

Can this insight into cognition settle the centuries of philosophical debate and show utilitarianism is a bad position? No. Why base your actions on what you feel like doing, dis­counting all other outcomes? All it says about utilitarianism is that it doesn’t come easily to the hu­man mind.

This research is just another bit of evidence that moral reasoning is guided by evolution and brain design, not some transcendental truth in the sky. It may still be useful of course, like other skills our mind provides us with, like a capacity to value things, a prefer­ence for being alive, and the abil­ity to tell pleasure from pain.

Next time you are in a mor­ally fraught argument, consider what Ghandi said: “Victory at­tained by violence is tantamount to a defeat, for it is momentary’” He’s right; genetic modification would be more long-lasting. Un­til this is available though, why not try something persuasive like a scalpel to the forehead?

Why aren’t our property rights over one another more transferable?

Posted on November 10, 2007 | 7 comments

Why do people get married? If anyone ever proposes to me for a reason other than to surreptitiously steal my belongings or to get more centerlink benefits, I would have to refuse them on the basis that I could not love a man so irrational.

~ all married/engaged folks please forgive me and freely assume I’m just rather jealous :) ~

What is the purpose of a contract to love someone forever?
If you anticipate loving them forever anyway, it would seem to be pointless. I’m told it is romantic nonetheless, but how is it romantic to take a legal precaution that implies some doubt that you will love each other forever?
On the off chance that you stop being in love with them, the last thing you want is to be legally bound to stick with them. And a legal obligation to actually love them is pretty laughable. Possibly if they stop loving you you might want them to stick around regardless, but isn’t that rather selfish and desperate? Anyway, surely this is hardly the contingency people have in mind when saying their vows.

Anyway, now that divorce is allowed the whole thing seems to be completely meaningless, except if understood as a way of betting large swathes of assets on the outcomes of ones emotional attachments, with divorce lawyers and priests playing casino. If this is the kind of gambling that floats your boat it makes perfect sense, but perhaps you could benefit from counselling at some point.

I propose a solution for escaping most of the potential damage of weddings while retaining the romance they apparently emanate: short term marriage contracts. At the end of, say, six months (terms such as length should be completely flexible) you renew it, or don’t, and act accordingly. If your spouse forgets this anniversary you can give them a year off. The whole ceremony could be the same as before, with a minor alteration to the vows: ‘…in sickness or in health, to love and to cherish ’til death or May 17 – whichever comes first, do us part’. Plus you can have more parties later on.

(On the earlier point, if anyone is ever irrational enough to propose to me, and I usually consider them rational, perhaps I must conclude that they are irrational specifically with regards to me, so therefore may in fact love me. A heuristic for finding selectively crazy guys could be just what one needs. If this occurs then you all have permission to laugh at me lots.)
