In a Crash, Should Self-Driving Cars Save Passengers or Pedestrians? 2 Million People Weigh In (pbs.org)

In what is referred to as the "Moral Machine Experiment", a survey of more than two million people from nearly every country on the planet, people preferred to save humans over animals, young over old, and more people over fewer. From a report: Since 2016, scientists have posed this scenario to folks around the world through the "Moral Machine," an online platform hosted by the Massachusetts Institute of Technology that gauges how humans respond to ethical decisions made by artificial intelligence. On Wednesday, the team behind the Moral Machine released responses from more than two million people spanning 233 countries, dependencies and territories. They found a few universal decisions -- for instance, respondents preferred to save a person over an animal, and young people over older people -- but other responses differed by regional cultures and economic status.

The study's findings offer clues on how to ethically program driverless vehicles based on regional preferences, but the study also highlights underlying diversity issues in the tech industry -- namely that it leaves out voices in the developing world. The Moral Machine uses a quiz to give participants randomly generated sets of 13 questions. Each scenario has two choices: You save the car's passengers or you save the pedestrians. However, the characteristics of the passengers and pedestrians varied randomly -- including by gender, age, social status and physical fitness. What they found: The researchers identified three relatively universal preferences. On average, people wanted: to spare human lives over animals, save more lives over fewer, prioritize young people over old ones. When respondents' preferences did differ, they were highly correlated to cultural and economic differences between countries. For instance, people who were more tolerant of illegal jaywalking tended to be from countries with weaker governance, nations who had a large cultural distance from the U.S. and places that do not value individualism as highly. These distinct cultural preferences could dictate whether a jaywalking pedestrian deserves the same protection as pedestrians crossing the road legally in the event they're hit by a self-driving car.

      No, actually, we're going to let the traffic engineers at the Department of Transportation set the rules, which will be the same as for humans (stay in lane, stop as fast as you can, DO NOT SWERVE) and the engineers won't even ask the public.

      The passengers have seatbelts, air bags, and crumple zones to lessen their injuries

      The question is usually framed to already take that into account. They way I have heard it is:

      Choice 1: Hit pedestrian.
      Choice 2: Drive off a cliff and kill the passenger.

      It may be an interesting philosophical question, but it has little to do with reality. A scenario like that is almost never going to happen, and even if it did, a human driver would be faced with the same split second dilemma and be no more likely to make the "correct" decision (whatever that is).

      Far more important is that the SDC would have much better reaction time, more braking distance, better control of steering, more situational awareness of other traffic, and thus better able to kill no one.

      While this is an interesting hypothetical scenario, I might suggest that the number of times that this sort of thing has actually been any kind of real choice to have to make, particularly in a situation that was not preventable by paying enough attention to the road in the first place, is probably countable on one hand in the entire history of automobiles, if not actually entirely non-existent.

      The ideal is that the self-driving car would be paying enough attention (tirelessly, I might add) to the road and what lies ahead that this sort of "kill the driver or kill the pedestrian" situation that people like to dream up wouldn't ever arise in practice... an automated car that is genuinely designed for safety would simply not drive so fast in any sort of hypothetically reduced visibility situation that there would not be enough time to stop safely in the first place.

      That's why you're supposed to be watching for people who look like they're about to jump into the road and drive at a reasonable speed so you can stop. If you can't see around an obstacle, you assume a person could walk out from there and drive at a reasonable speed so you can stop. An automated car will need to anticipate the same type of situations "those two people on the sidewalk are.an adult who is holding a child's hand, therefore the child is not likely to run out", or "the adult is not holding the child's hand and he is running everywhere, he may run onto the road".

      Citation needed.
      Anyway...
      Jaywalking is only called as such if it's a crime. Otherwise it's called "crossing the road". So let's focus on where it indeed is illegal to cross the road wherever you feel like.
      Jaywalking was always a tricky thing. There are many variables to consider.
      Is it okay to cross a road through an unmarked location, if the road is empty for hundreds of yards either way or with no car in sight?
      Is it okay to play IRL Frogger in a busy intersection in the middle of the city?

      Personally, I am a strong supporter of (enforcing) heavy fines in case of jaywalking anywhere within a city or town's borders, with the exception of single-lane, one-way streets with speed bumpers or speed limit below 15 mph. The reason for this is my belief that a civilized society is based on respecting the "small rules": no littering, no jaywalking, no unruly behavior, no making a lot of noise, you know, common sense things.
      I'm from a country where jaywalking is punished... in theory. In practice, nobody gives a flying fuck, and as a result I stay at the red light with my little kids and everyone else just jaywalks, so I struggle to properly educate my kids to be civilized because everyone else shows them, through their apish behavior, that their dad is an idiot for following simple common sense rules. Am I an idiot for teaching my kids a civilized rule?
      In the past I used to work as a camera man for a local branch of a country-wide private TV channel. One of my tasks was to document all major incidents for the local police, as at the time they did not have their own camera man. I have documented car accidents, fires, demolitions gone wrong, suicides, homicides, pretty much anything with victims (be they wounded or killed). I've seen fatal effects of jaywalking, very closely and from a wide variety of angles. People who jaywalk have no fucking clue. I know exactly what I am keeping my kids away from, and I cringe every time I see parents dragging their kids across the road, in a hurry, because cars are coming with 30-40 mph. There was a case from back then where a parent with two kids jaywalked, one of the kids dropped his toy and pulled his hand from his father's, ran back to pick it up and was run over by a car. The other kid go scared and ran the other way, across the middle of the road and got hit by another car. The parent was unscathed but ended up with one dead child and another crippled for life. All because he decided not to wait for 30 more seconds.

      So yeah, it doesn't matter if jaywalking is a crime. Before it being a crime, it's a common sense rule. It became a crime because people lack common sense, so it needs to be hammered into their thick skulls with fines and such.

    You never know for certain that a given course of action will cause a fatality. When you're driving, you try to avoid accident. Self-driving cars will do the same. They'll compute the odds of an accident for all options and select the one with the lowest odds. It may be just a fraction of a percent less likely, but it will take that.

    The US is a nation composed largely of immigrants and their offspring, many who have arrived comparatively recently. In many cases they came not because it was convenient (getting to the US from Poland or Italy, for example, was not "convenient" before air travel - esp. for poor people) or because it was easy or because it was low risk. They subjected themselves to substantial risk, expense, and inconvenience to make the trip and survive in the US.

    These immigrants, of course, left behind those that didn't have the same drive or interest in creating a better situation for themselves and their families. It would not be surprising that those who had the gumption to better themselves rather than sacrifice themselves for the "common good" would be looking out for themselves and their families more strongly than those that lacked such gumption and remained behind.

    As well, the US has historically been one of the most diverse populations in the world (due to the source of our population) so the tribal "common good" notion is probably unsurprisingly much stronger than in monocultures like Japan or most of the Nordic countries.

    The US seems to have done pretty well - esp. in light of having to deal with its very diverse population.

  8. I don't think Jefferson was evil, but ACs are by DanDD · · Score: 3, Insightful

    From the very foundation that manages the estate of Thomas Jefferson at the home he built, Monticello, including his descendants, both black and white:

    “Though enslaved, Sally Hemings helped shape her life and the lives of her children, who got an almost 50-year head start on emancipation, escaping the system that had engulfed their ancestors and millions of others. Whatever we may feel about it today, this was important to her.”

    Pulitzer Prize-winning historian Annette Gordon-Reed, 2017

    I don't think Thomas Jefferson was quite as evil as you make him out to be. He seems to have been more interested in keeping his relationship with Sally Hemings secret, rather than in keeping anyone a slave. I also challenge you to produce a record of Jefferson selling any of his children with Sally Hemings, or a record of any of Sally's children being abused. Jefferson went out of his way to provide Sally with a private adjoining bedroom with his own. This woman had unfettered access to Jefferson. She could have easily killed him in his sleep, for decades, but she didn't. They also fell in love while in France, where mixed race relationships where no big deal.

    It's also not fair to use modern values to judge those from a different culture and era. If you have references to paint a clear picture of Jefferson as someone who was truly evil, rather than someone who was trying to avoid persecution for a forbidden love, I'd love to see them.

    Jefferson did leave clear instructions that all his slaves were to be freed, but I don't think this happened until after he died. I do love history, but I do not claim to be knowledgeable about Jefferson, although I have visited his home.

    If you want an example of evil in the founding fathers of US history - look at Alexander Hamilton. That SOB used anonymous news articles and stories to libel and belittle Aaron Burr for decades, a rather competent military man who went on to become vice president. Both Burr and Jefferson were not terribly fond of Hamilton's Federalist agenda, which has issues reverberating in American politics to this day.

    Burr eventually got tired of Hamilton's shit and challenged him to a duel, which was accepted. Hamilton, being inept with a pistol, his few competencies being running his mouth and flinging ink with his pen, lost the duel and died. A fitting end for an Anonymous Coward.

  9. engineers vs. philosophers by Tom · · Score: 3, Interesting

    It's a cute experiment with not exactly surprising results (humans prefer humans over animals - who'd have thought?).

    But in the end, like the trolley experiment, it is informative and insightful and a bunch of other +5 mod points buzzwords, but the actual solution for the real world will be made by engineers, not by philosophers, and it will almost certainly not involve a "moral decision" subsystem. The primary effort of a practical AI is in making a decision so quickly that it can still minimize damage. Every CPU cycle wasted on evaluating the data in other ways is silly. It will rely for its decision on whatever data its sensors have already provided, and that data will not be in the shape or form of "there are 3 black people with this age range and these fitness indicators in the car, here are their yearly incomes, family relations and social responsibilities. Outside the car we can choose between the river, average temperature 2 degrees, giving the passengers this table of survival probabilities. Or crowd A, here is a data set of their apparent age, social status and survival probabilities. Or crowd B, here is their data set."

    This is how the philosopher imagines the problem would be stated to the AI - or to a human in a survey.

    But in reality, the question will be more likely something like: "Collision avoidance subsystem. Here's some noisy sensor data that looks like the road ends over there. A bunch of pixels to the left could be people, number unclear. A bunch of pixels to the right also seem to be people, trajectory prediction subsystem has just given up on them because they're running fuck knows where. Estimated time to impact: 0.5 seconds. You have 1 ms to plot a course somewhere or it doesn't make a difference anymore. Figure something out, I need to adjust the volume on the infotainment system and make the crash warning icon blink."

    What we will end up with is some general heuristics, like "don't crash into people if you can avoid it" and then the AI will somehow come up with some result, and it will work ok in most cases in the simulator, and then it will be installed in cars.
