the dunning-kruger effect

random stuff, science 2 Comments »

I just came across the so-called Dunning-Kruger effect, which looks like a rather psychological thing. Since I never heard of that name before (although I’m familiar with some of the studies), I asked a couple of psychologists I’m having breakfast with currently, none of them knew the effect either.

Have you heard of it before?

The Dunning–Kruger effect is a cognitive bias in which “people reach erroneous conclusions and make unfortunate choices but their incompetence robs them of the metacognitive ability to realize it”. The unskilled therefore suffer from illusory superiority, rating their own ability as above average, much higher than in actuality; by contrast the highly skilled underrate their abilities, suffering from illusory inferiority. [...] “Thus, the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others.”

(Quotes from Kruger & Dunning, 1999, Source: Wikipedia)

Bertrand Russell had a funny way to put it:

The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.

earthquake shortens days

mad world, random stuff, science 0 Comment »

The magnitude 8.8 earthquake in Chile last Saturday actually shifted the axis of the Earth by 8 centimeters. This led to an increase of the rotation of the Earth, which shortens the days by 1.26 microseconds (0.00000126 seconds). Unfortunately, this can only be calculated, not actually measured. The smallest amount of time that can currently be captured is 5 microseconds.

Now, what does that mean?

Even less sleep for me, I guess.

Sigh.

In comparison to Chile, the 2004 Sumatran earthquake (magnitude 9.1) is estimated to have shortened the length of day by 6.8 microseconds and shifted Earth’s axis by 7 centimeters. It did not have an impact as strong as the one in Chile – JPL research scientist Richard Gross explains why:

First, unlike the 2004 Sumatran earthquake, which was located near the equator, the 2010 Chilean earthquake was located in Earth’s mid-latitudes, which makes it more effective in shifting Earth’s figure axis. Second, the fault responsible for the 2010 Chiliean earthquake dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake. This makes the Chile fault more effective in moving Earth’s mass vertically and hence more effective in shifting Earth’s figure axis.

happy holidays

May you be touched by HIS noodly appendages and have a happy FS-Mas. May HIS INVISIBLE NOODLY GRACE bestow upon you lots of meat-balls. May OUR NOODLY CREATOR take care that the stripper factories and beer volcanos in heaven never run dry.

May you have a blessed holiday!

RAmen.

As has been noted previously in blog discussions, it is possible that Christian usage of the “ball”-type ornament to decorate their holiday trees actually originated as an homage to His divine meatballs and that the garlands or strands of lights used on Christian holiday trees are in fact merely a representation of His noodly appendages.

Lena Schöneborn hat das erste Olympia-Gold für Deutschland im Modernen Fünfkampf seit 72 Jahren gewonnen.

Naja, so modern kann der moderne Fünfkampf ja wohl nicht sein …

in your face, DSDS!

all posts, germany, random stuff 2 Comments »

Für eine neue Staffel der Castingserie “Deutschland sucht den Superstar” (abgekürzt DSDS) hatte RTL bei der Stadt Bremen angefragt, ob das Casting für einen regionalen Vorentscheid im Bremer Rathaus erfolgen kann.

Bürgermeister Jens Böhrnsen (SPD):

Die Kandidatinnen und Kandidaten werden bei der Sendung vor einem Millionenpublikum mit Häme, Spott und Beleidigungen überzogen und lächerlich gemacht [...] Sie werden gezielt erniedrigt.

Böhrnsen sagte weiter, die Kommission für Jugendschutz der Landesmedienanstalten sei zu dem Schluss gekommen, dass beleidigende Äußerungen und antisoziales Verhaltung in der Sendung als Normalität hingestellt würden. Die Bremer Bemühungen um eine von gegenseitigem Respekt und Toleranz geprägt Jugendkultur würden durch ein solches Sendeformat geradezu konterkariert.

Schön, dass mal einer sagt, was Sache ist, und den Trend anspricht, den das deutsche Fernsehen seit 5+ Jahren immer weiter verfolgt. Umso trauriger, dass die Leute genau das sehen wollen. Es sagt schon einiges über den Selbstwert von Menschen aus, die gerne sehen, wie andere erniedrigt werden – gemischt mit Sensationsgier, versteht sich. Wenn das so weitergeht, steht in 10 Jahren das erste moderne Colosseum in Europa …

volbeat, choices and modern heavy metal culture

all posts, ego, english, random stuff 7 Comments »

Okay, here we go.
I’m afraid this will be a fairly long entry, as I had plenty of time to think about it yesterday night on the long and arduous way home (long live the public transportation in Munich) …

Life is about choices, and every choice you make also means not chosing the various alternatives. The human psyche is constructed in a way that, after making a decision, it usually takes care that we don’t doubt a lot. We convince ourselves that the choice we made was the best one, and that the other alternatives weren’t really good options anyway (there is a lot of interesting psychological research to the topic, see this video as an example).

These mechanisms are a bit screwed up in my brain, I doubt a lot, especially regarding choices. About alternatives I could have taken, about other paths I could have chosen – but yesterday night, it felt like there was only one place on this planet to be, it felt like I made the right decision: I was at the Volbeat concert in Augsburg.

Now let me tell you about the Rockfabrik where the concert took place:

“Am I going to have a problem with you, Mr. Bond?”
- “No, don’t worry, you’re not my type.”
“Smart?”
- “No, single.”

While searching for the new Southpark Easter Episode on Youtube, I for the first time encountered:

############################################################

Things do change, after all. Sad on the one hand, very good to understand on the other. Youtube was sharing videos protected by copyright for years without getting into trouble.

schlechte menschen

all posts, random stuff 14 Comments »

Jeder kennt sie, keiner mag sie: schlechte Menschen. Sie verbreiten schlechte Launa, ein ungutes Gefühl bekommt einen, wenn man in ihre Nähe kommt, eine zuerst unbewußte, aber dann sehr spezifische Abneigung macht sich breit; man wird gemein, wendet sich von ihnen ab, und sucht im besten Fall das Weite …

Lange habe ich darüber nachgedacht, was diese schlechten Menschen – die jeder von uns kennt – ausmacht, was sie determiniert, wie sie bestimmt, klassifiziert, definiert werden können. Was macht sie zu schlechten Menschen, und was unterscheidet sie von mir?
Ich habe heute früh endlich eine Lösung gefunden:

Schlechter Mensch, der; ein ~ ist eine männliche oder weibliche Person die, so sie irgendwo arbeitet, wo es Kassen gibt, z.B. in einem Supermarkt, einer Tankstelle oder einer Bäckerei, dem Kunden trotz dessen Freundlichkeit und direkt neben dem aufgestellten Rückgeldteller aufgehaltener Hand das Wechselgeld lieber auf just erwähnten Teller legt, anstatt in die Hand des Kunden, und dies zu allem Überfluß auch dann tun würde, wenn sie überhaupt nicht in einem der genannten Geschäfte arbeiten würde, da es sich um einen tiefes phänotypisches Charakteristikum der ~ handelt, was sich nur unter gewissen Umständen, dann aber sehr zuverlässig zeigt.

Im übrigen bedingt die Existenz schlechter Menschen nicht notwendigerweise die Existenz von guten Menschen.
