Never Tell Me The Odds

We could learn lots about what others think of us if we would just ask our associates directly.  But we mostly don’t, mainly because we are afraid of what we might hear:

People control the nature of their relationships, in part, by choosing to enter (or avoid) situations providing feedback about other people’s social interest. … Individuals experimentally primed to feel avoidant were less likely than those primed to feel secure to choose to receive feedback about how another person felt about them. Overall, the research suggests that choices of socially diagnostic versus socially nondiagnostic situations play an important role in guiding people’s social relationships.

War From Near And Far

Longtime OB commenter TGGP gives quotes showing the “near/far dichotomy is reflected in Randall Collins’ “Violence: A Microsociological Theory”:

Soldiers who have been in combat and had direct contact with the enemy tend to depict him as courageous; it is enemies on more distant combat zones who are not respected; and soldiers in rear areas, and even more so civilians at home, who express a low regard for the enemy. …

The higher the rank, the more the person identifies with the formal frontstage ideals of the organization and is likely to talk in official rhetoric. … The contrast between detailed observation of what is happening in each micro-situation, and summary accounts of an ideal-typical version of performance; the latter would tend to be more idealized toward a favorable image, and we would expect that this bias would grow with as the actual memories of combat experience become more distant. …

In the modern era, casualties were caused primarily by artillery fired at long distance. In the musket era of parade-ground formations, cannon operating closer to the battle line generally accounted for more than 50 percent of the casualties. … The sheer distance from the enemy, and especially being shielded from personally seeing the men one is trying to kill increases the level of [soldier] performance. …The tension/fear of combat is almost completely debilitating at close range. …

Pre-battle elation … [is] troops’ “strange and fearsome delight at being at last up ‘really’ up against it”. This is a case of feelings prior to these men’s first battle, still in the phase of rhetoric. … Soldiers in rear areas express more hatred of the enemy, and more ferocious attitudes toward them, than frontline troops. … Whereas combat soldiers are more likely to treat prisoners well … rear area troops tend to treat prisoners more callously. … Civilians at home are more likely to express violent rhetorical hatred. … This fits the general pattern of all fights: surrounded by bluster and gesture up until the actual fight situation, when the emotion shifts drastically and tension/fear takes over. …

The proportion of empty rhetoric expands with each step toward the rear; war is successively more idealized, the enemy successively more dehumanized, attitudes toward killing successively more callous, and the whole affair more like the cheering of sports fans. …

The circumstances that cause the most fear not necessarily those that are objectively the most dangerous. Artillery shells and mortars … cause by far the most casualties – and the soldiers themselves generally know that – but the greatest difficulty in combat performance is in confronting small-arms fire at the forward edge of the combat zone. …  The source of strain is neither fear of death and injury, nor aversion to killing in principle. … What is different, and what seems to buffer them from tension/fear, is that [officers] personally do not have to do the killing.

War is a powerful horrifying example of just how badly our minds can be deluded by our “idealistic” far view.  Our far view of war functions well to help us signal our loyalty and commitment to our associates, but it makes us far too willing to make war and be cruel to our enemy, and makes us too willing to use tech that can kill from afar.

Prefer Local Government

Government agencies waste money mainly because they are inefficient, not because they are corrupt.  Local governments waste a lot less.  More here:

We analyze procurement purchases by a representative sample of Italian public bodies over the period 2000-2005. Our dataset contains very detailed information on the purchase of 21 generic goods. For each purchase, this includes quantity, brand, model, specifications, delivery conditions, and — most importantly — the price paid. …

The average prices paid by different Italian public bodies vary substantially. The public body at the 90th percentile of the fixed effect distribution pays on average 55% more than the one at the 10th percentile. …

Differences across public bodies are correlated with institutional characteristics rather than geography or size. Semi-autonomous bodies (universities and health authorities) pay the lowest prices. Compared to these, the average town government pays 13% more. The difference increases further for regional governments (21%), social security institutions (22%), while the average ministry tops the list with 40% higher prices. …

At least 82% of estimated waste is passive and that passive waste accounts for the majority of waste in at least 83% of our sample public bodies. …  Overall our findings are consistent with the hypothesis that, in aggregate, most waste in the procurement of generic goods by the Italian public sector is not due to corruption but to inefficiency.

Scale diseconomies appear to be strong in government, as they are in the private sector.

What Is “Personal”?

Consider:

  1. People often say “It’s not personal, it’s just business”, or “This is personal.”
  2. We have laws to discourage discrimination based on gender, race, age, religion, etc., but they only apply at work, school, clubs, etc. and not to “personal” relations such as friends or lovers.
  3. Law let’s us sue firms or schools that lie to us, to discourage such lies, but not only can’t we sue our friends or lovers for their lies, law prohibits blackmail, which would otherwise discourage such lies.

What are other key differences in how we treat “impersonal” from “personal” arenas?  What is the essential difference that explains these differing treatments?

My tentative theory: our ancestors had different social norms for “personal” within-tribe versus “impersonal” between-tribe behavior.  When you interacted with someone from another tribe, you had to be more careful to be neutral and inoffensive, since your whole tribe might suffer if you offended someone.

War Is Peace

warmongerWar isn’t always bad; sometimes war is required.  And Obama may well be a better than average president.  But this is so strange:

  1. Many voted for Obama saying Bush was a warmonger.
  2. Obama just won the Nobel Peace Prize.
  3. Obama doubled US troops in Afghanistan, for a net increase in US troops at war.

Med Decides If We’ll Get Richer

Since US med spending is now 18% of income, and is rising faster than other spending, then whether we get richer or poorer over the next half century or so mainly depends on whether we get much added value from increased med spending.  If, as I and many others have suggested, we gain relatively little from more med spending, we may actually get poorer.

Chernew, Hirth and Cutler in Health Affairs:

At approximately long-run average rates of excess health spending growth, 119 percent of the real increase in per capita income would be devoted to health spending over the 2007–2083 projection period. We argue that an alternative scenario, under which health spending grew just one percentage point faster than real per capita income, is “affordable,” although 53.6 percent of real income growth over the period would go to health care. … This analysis thus supports the argument that reforms that would dramatically slow the rate of health care spending growth are necessary.

Robert Samuelson in the Post:

Per capita GDP … from 2007 to 2030, it’s projected to rise from $43,900 to $60,600. That’s a 38 percent increase … Unless controlled, rising health spending would absorb much of that gain. The increase in per capita GDP from 2007 to 2030 is $16,700. If health spending continued to grow at past rates, it would go from $7,100 per person in 2007 to $15,300 in 2030. This rise of $8,200 is half the overall gain ($16,700) in per capita income. …

One study … [said] continuation of present [med spending] trends would result in “falling wages at the bottom of the earnings spectrum and very slow wage growth on up the earnings distribution. These dismal wage outcomes would persist over at least the next couple of decades.”  To be sure … some care extends life and improves quality of life. But the connections between being healthy and more health spending are loose. … Most people … get few benefits from high spending.

Of course this increased med spending, and reduced other wealth, would be an overall good deal if increased med spending dramatically improved our health.  But the median med policy wonk, who says we must hold down med cost growth, clearly has doubts about the value of added med spending.  Regardless of where your opinion sits here, let us agree: the net health value of added med spending is one of the most important research questions around; it largely determines if we will get richer or poorer over the next half century.

Yet I’d guess the number of full time equivalent researchers working on this is less than a few dozen, perhaps less than a dozen.   Why so few working on such an obviously central question?

Sex is Near, Love is Far

Sex is near and love is far, logical analysis is near while “aha” creativity is far, and conventional art is near while unconventional art is far.  These results seem to confirm my suggestion that near mode emphasizes practical action, while far mode emphasizes social image.  Sex is more what we really want, while love is more how we present ourselves to get such things.  Analysis tends to be more practical, while “creativity” and unconventionality is more done to show off.  More here and here:

When in love, people typically focus on a long-term perspective, which should enhance holistic thinking and thereby creative thought, whereas when experiencing sexual encounters, they focus on the present and on concrete details enhancing analytic thinking. … Two studies … found support for this hypothesis. …

Participants primed with love reported more wishes, goals, or events that related to future events compared to participants primed with sex or those in the control group …

The creative insight task … is (a) ultimately soluble, (b) likely to produce an impasse during the solution, and (3) likely to produce an “aha!” experience when the solution is discovered after prolonged efforts. An example: …

A dealer in antique coins got an offer to buy a beautiful bronze coin. The coin had an emperor’s head on one side and the date 544 B.C. stamped on the other. The dealer examined the coin, but instead of buying it, he called the police. Why? …

For the analytic thinking task, four logic problems from the Graduate Record Examination (GRE) of the form “If A < B and C > B then?” … involve evaluating the truth value of a number of propositions given an initial set of basic facts. … Continue reading "Sex is Near, Love is Far" »

Is Mass Transit Green?

Brad Templeton:

That transit is a significantly greener way to get around than private car travel almost goes without saying in our thoughts and discussions. Disturbingly, this simply isn’t true. … City diesel buses and electric trolley buses are both mildly worse than the car in energy efficiency. Light rail systems are also slightly worse, on average, though it varies a lot from city to city. Commuter rail and subway (heavy rail) trains tend to be a bit better, but not a lot better.

transit-mpg

Passenger Miles Per Gallon

What’s not in these numbers … energy to make and recycle cars and transit vehicles. … to build and maintain roads … and tracks … to extract, refine and ship fuel …

In spite of [these numbers], it is always the green move for any individual to take existing mass transit over their car. That’s because the transit is running anyway, so the incremental cost of carrying one more passenger is indeed less than just about any private vehicle.

This is a common way to analyze marginal costs, but I wonder.  When one rides mass transit one not only makes the train a bit heavier, one also makes it a bit more crowded, discouraging other passengers.  Worse, one makes all future transit planners estimate that a slightly higher fraction of the population is willing to ride mass transit, encouraging them to build more and large transit systems.  It seems to me that this last effect could bring the marginal cost of using mass transit back up to near its observed average cost, i.e., about the same than cars.

Let’s Not Kill All The Lawyers

The first thing we do, let’s kill all the lawyers. King Henry VI

Commenters on yesterday’s law post are obsessed with the scenario where future robots exterminate humans.  From my ’94 essay If Uploads Come First:

What if short people revolt tonight, and kill all the tall people?  In general, most societies have many potential subgroups who could plausibly take over by force, if they could coordinate among themselves. But such revolt is rare in practice; short people know that if they kill all the tall folks tonight, all the blond people might go next week, and who knows where it would all end? And short people are highly integrated into society; some of their best friends are tall people.

In contrast, violence is more common between geographic and culturally separated subgroups. Neighboring nations have gone to war, ethnic minorities have revolted against governments run by other ethnicities, and slaves and other sharply segregated economic classes have rebelled.

Thus the best way to keep the peace with uploads would be to allow them as full as possible integration in with the rest of society. Let them live and work with ordinary people, and let them loan and sell to each other through the same institutions they use to deal with ordinary humans. Banning uploads into space, the seas, or the attic so as not to shock other folks might be ill-advised. Imposing especially heavy upload taxes, or treating uploads as property, as just software someone owns or as non-human slaves like dogs, might be especially unwise.

It is always possible in principle for everyone but some small group to agree to violate the previous law and peace and exterminate or enslave that small group.  We could for example do this to retirees today, and avoid their being “useless parasites” on society.   We could similarly eliminate some sick, weak, mentally ill, stupid, or idle rich.  But we don’t.  Why?

We would suffer large costs to coordinate to do this, so the group we “eat” would need to be large enough to make this predation pay.  And this first act of coordination would lower the cost of similar coordinations on more small groups after that, and so each of us would acquire an heightened fear of being “eaten” in further rounds of extermination or enslavement.  These “slippery slope” expectations greatly add to the perceived cost of any first round of such coordinated predation.

This predation coordination is also much more expensive for groups that are well integrated into our society.  Such groups would hear early about the proposal to eat them, retaliate against the proposers, suggest other groups to eat instead, and in the worse case actively resist plan implementation.  Their elimination would disrupt their many relations with others, and harm many others who care about them or see such predation as immoral.

As long as future robots remain well integrated into society, and become more powerful gradually and peacefully, at each step respecting the law we use to keep the peace among ourselves, and also to keep the peace between them, I see no more reason for them to exterminate us than we now have to exterminate retirees or everyone over 100 years old.  We live now in a world where some of us are many times more powerful than others, and yet we still use law to keep the peace, because we fear the consequences of violating that peace.  Let’s try to keep it that way.

Prefer Law To Values

On Tuesday I asked my law & econ undergrads what sort of future robots (AIs computers etc.) they would want, if they could have any sort they wanted.  Most seemed to want weak vulnerable robots that would stay lower in status, e.g., short, stupid, short-lived, easily killed, and without independent values. When I asked “what if I chose to become a robot?”, they said I should lose all human privileges, and be treated like the other robots.  I winced; seems anti-robot feelings are even stronger than anti-immigrant feelings, which bodes for a stormy robot transition.

At a workshop following last weekend’s Singularity Summit two dozen thoughtful experts mostly agreed that it is very important that future robots have the right values.  It was heartening that most were willing accept high status robots, with vast impressive capabilities, but even so I thought they missed the big picture.  Let me explain.

Imagine that you were forced to leave your current nation, and had to choose another place to live.  Would you seek a nation where the people there were short, stupid, sickly, etc.?  Would you select a nation based on what the World Values Survey says about typical survey question responses there?

I doubt it.  Besides wanting a place with people you already know and like, you’d want a place where you could “prosper”, i.e., where they valued the skills you had to offer, had many nice products and services you valued for cheap, and where predation was kept in check, so that you didn’t much have to fear theft of your life, limb, or livelihood.  If you similarly had to choose a place to retire, you might pay less attention to whether they valued your skills, but you would still look for people you knew and liked, low prices on stuff you liked, and predation kept in check.
