Barry schwartz held an excellent talk at TED: “Our loss of wisdom” (YouTube, full lesson on TED Ed). A few quotes (not all of them are literal):

  • The job description of a hospital janitor includes many kinds of tasks but not a single one involves other human beings. Not one. Yet, when you look at what janitors tell you when you ask them about your job, it’s always about other people:
    • Mark stopped mopping the floor because a patient had got up and did exercises in the corridor.
    • One janitor refused to vacuum the visitors lounge because family members slept there despite orders of her superior.
    • Luke washed the floor in a comatose patients room twice because a relative hadn’t noticed him doing it the first time.
  • Not all janitors are like this but those who are think these are essential parts of the job.
  • “These janitors have the moral will to do right by other people and beyond this the moral skill to figure out what doing right means.”
  • “A Wise Person Knows: When and how to make ‘the exception to every rule.'”
  • “A Wise Person Knows: When and how to improvise.”
  • “A Wise Person Knows: How to use these moral skills in pursuit of the right aims.”
  • “A Wise Person: Is made and not born.”
  • It takes experience to become wise and not just any experience: You need the permission to be allowed to improvise, to try new things, occasionally to fail and to learn from your failures.
  • “You don’t need to be brilliant to be wise. The bad news is that without wisdom, brilliance isn’t enough.”
  • @05:57, he tells a story how people with good intentions ruin the lives of a family for several weeks just by obediently following rules. All people involved said “we hate to do it but we have to follow procedure.”
  • “Rules and procedures may be dumb but they spare you from thinking.” (- and they allow you to blame others)
  • When things go wrong, we turn to two tools: Rules and incentives. When something happens, we want better ones and more of them. That happened after the financial crisis: Regulate, regulate, regulate, fix the incentives, fix the incentives, fix the incentives. @8:21 “The truth is: Neither rules nor incentives are enough to do the job.” How do you pay people a bonus for being emphatic?
  • Rules and incentives help in the short run but they create a downwards spiral in the long run.
  • By relying on rules, we engage in a war on wisdom. Rules help prevent disaster but they also ensure mediocrity (@10:30). We need enough rules but not too many.
  • Incentives seem better. But sometimes, they compete with the original goal instead of complementing it. We suddenly stop asking “What is my responsibility?” and turn to “What serves me best?”
  • Solution? Smarter incentives. Unfortunately, there will never be incentives which will be smart enough. We need incentives but excessive incentives demoralize: “It causes people who engage in that activity to lose morale and it causes the activity itself to lose morality.”
  • “We must ask, not just is it profitable, but is it right.” – Barack Obama, 18th Dec 2008.
  • What doesn’t work: Teach more ethics courses. “There is no better way to show people that you’re not serious than to tie everything you have to say about ethics in a ball and consign it to the margins as an ethics course.”
  • What to do instead? See for yourself @14:25

How Incentives (Don’t) Work

2. January, 2013

Ever wondered why companies do better when they don’t pay bonuses to managers?

In a nutshell, incentives occupy your brain. If your brain has to make complex decisions, then incentives reduce the amount of free brainpower available to solve problems. The result is poorer performance, not despite, but because of the bonus.

For details, see my old (updated) blog post: Bonus is Bad For Motivation


NRA Turns Schools Into Shooting Ranges

26. December, 2012

Some people seem to object to the stance of the NRA after the last massacre in ConnecticutLaPierre says:

The only thing that stops a bad guy with a gun is a good guy with a gun. (source)

Translation:

I know, like any sane person, the only thing that really stops a bad guy is making it harder to gain access to guns. But me and my colleagues make billions of dollars by selling arms to id… err … lu… err … customers. A little bit of collateral damage is to be expected when this amount of money is turned over, right? You can’t really expect us to give up our fortunes just because a few hundred people get killed every year. If we don’t make it, someone else will get rich.

Of course, he can’t say that. Instead, he points at scapegoats: Video games and violent media.

Penny Arcade summarized this in the Christmas strip:

It is a very odd sort of Patriot that would destroy the First Amendment to protect the Second.

There is no study which can show that violent video games turn anyone into a killer but it sounds good. Killers prefer violent games but not every gamer is a killer – claims to the opposite are a result of overgeneralization. Some studies claim that violent persons use video games to reduce stress, delaying outbursts of violence. Humans are no simple machines; there is no surefire way to know beforehand how someone reacts to something in advance.

What science does show is that a healthy social life will prevent these incidents. But you can’t sell those. Which means the NRA will stick to what they know following the old “wisdom”: “If all you have is a hammer, everything looks like a nail

Still not convinced?

  • Why do hunters need machine guns?
  • Is a machine gun (which goes quickly through the ammunition) really better to protect the USA?
  • Why doesn’t Switzerland have the same problem? They have 45.7 guns per 100 residents (US has 88.8) but only 0.52 people (out of 100’000) are killed with firearms (3.7 in the US, about 5 times more taking the guns per resident into account)

Some reasons why Switzerland fares better than the US:

  • Most people get their rifle during military service. Which means: Only people who have went through basic training get a gun (= most instable persons are sorted out).
  • Military rifles must be presented once per year during the mandatory shooting training.
  • When the training ends (usually at age of 35), you must return the rifle and all ammunition.
  • Ammunition is only dispersed in sealed containers. Ammunition is checked during the yearly training and broken seals mean trouble.
  • Rifles must be locked away.
  • Ammunition must be kept in a different place and also locked away.
  • The striker must not be installed while the rifle is stored.
  • Machine guns are not for sale anywhere. If you want one, you either need to join special forces (police or military) with the additional personal background checks plus training. Or you can try to get one illegally. Which isn’t a good idea. The police hates people with machine guns and if they catch you, they will make sure you notice.
  • Hunters and shooting fans need special permits, training and there is a whole slew of laws and regulations. You don’t get a gun for fun in Switzerland.

So Switzerland is proof that strict laws do work. It also means that Swiss arms makers have to sell most of their goods in other countries. Like the US …

The Meaning of Life

24. December, 2012

Minimize suffering.

Examples:

  • We like to help others, minimizing their suffering (main goal of helping others) and our own (we feel shame when we see someone who needs help or sometimes even feel their pain as if it was our own)
  • Laws are designed to minimize suffering. Revenge might be our first instinct but it never minimizes anything. Like the old says: Eye for an eye leaves everyone blind. That might minimize insight but not the pain.
  • Even the most simple animals avoid pain. Plants try to grow out of shade. Excited electrons quickly return to their normal state – a phenomenon which allows us to see.
  • Moral and ethical guidelines help to minimize suffering. Apart from the obvious effects, they help members of the group to behave well without suffering through the long and tedious process of discovering those truths themselves.
  • Religions try to minimize suffering by giving explanations for the inexplicable. Buddhism boiled everything down to this phrase: “Life means suffering” (from The Four Noble Truths[*]).

Merry Christmas and a Painless New Year.

[*]: And their solution isn’t death, it’s ascension – Nirvana: “Nirvana means freedom from all worries, troubles, complexes, fabrications and ideas. Nirvana is not comprehensible for those who have not attained it.”


Designing a Garbage Bin

17. December, 2012

Many of us have noticed that designing software is surprisingly hard but many don’t know why that is. The simple answer: Design is the art to balance contradicting goals.

Not convinced?

Let’s design a public garbage bin together.

What do we want?

  1. Big enough so it never spills
  2. Easy to clean
  3. Nice to look at
  4. Robust enough to withstand riots
  5. Soft enough to cushion the impact of car
  6. Long lifetime
  7. Cheap

It’s easy to see that “cheap” contradicts almost anything else. “Nice to look at” means an (expensive) artist has to build the form. Big garbage bins ain’t cheap. Easy to clean and robust mean high quality materials for hinges and locks. Easy to clean and long lifetime involve expensive surface materials and finishing.

It should be easy to lift for the cleaning crew but not for rioters. When a car hits it, the bin should give way. So these contradict each other as well.

Still not convinced? Look at my elevator example.


The End is Nigh

12. September, 2012

No, the world doesn’t end 2012 but it will soon be a much less hospitable place for us humans. Before I share my view, what do you believe will be the most prominent factor in the massive reduction of the human population?

Update: Polldaddy didn’t keep my poll alive and I missed to copy the results before it was gone. Sorry for that.

I do so knowing that along some paths of cosmic discovery
There are times when, at least for now,
One must be content to love the questions themselves
