Hopefully some interesting bits of information extracted from science and non-fiction literature. (For historical reasons there are some poems scattered throughout this blog.) Sachthemen und Sachtexte. (Historisch finden sich auf diesem Blog auch einige Gedichte und Aphorismen.) [Just collecting some exciting bits of information here.] [Eine Sammlung von interessanten Texten, Fragen und Antworten will das hier sein. Nicht mehr, aber auch nicht weniger.]

Individual differences in risk-propensity:

Individual differences in risk-propensity: Associations between personality and behavioral measures of risk
Sandeep Mishra and Martin L Lalumiere

Abstract

Previous research has demonstrated that various forms of risky behavior are highly associated among individuals, and such personality traits as impulsivity, sensation-seeking, and low self-control are correlated with risk-taking. However, little evidence indicates that self-report measures of personality traits associated with risky behavior significantly correlate with a behavioral preference for risk. We examined whether personality questionnaire measures of traits associated with risk (impulsivity, sensation-seeking, low self-control) were correlated with various behavioral measures of risk (future discounting, probabilistic risky choice). We show that measures of risk-propensity comprise three principal components: Future Discounting, Risky Personality, and Variance Preference. Risky Personality and Variance Preference were significantly correlated. Future Discounting was not associated with either of the other risk components. Together, the results provide some evidence suggesting that stable personality traits may represent proximate mechanisms through which a behavioral preference for risky outcomes manifests.

(Linda S. Gottfredson)

"If our professions do not allow us to devote more than two hours a day to a subject, do not abandon the work on the pretext that we need four or six. As Payot wisely noted, 'A little each day is enough, as long as a little is produced each day.' "

"So zu lesen und zu studiren, daß es sich immer ansezt, kan ich rathen, obgleich die Welt nicht an mir den Nutzen dieses Rathes sieht, ich gebe ihn nicht weil ich ihn durch häufige Erfahrung nützlich befunden habe, sondern, weil ich jezt sehe und deutlich, daß ich ihn hätte befolgen sollen."

(Georg Cristoph Lichtenberg)

"no matter who your are, your joie de vivre mostly derives from paying attention to someone or something that interests you."

"Every organism, whether a bacterium or a member of Homo sapiens, has a set of things in the world that matter to it and which it (therefore) needs to discriminate and anticipate as best it can."

"The key, Paul [Silvia] explained, is that novelty for the beginner comes in one form, and novelty for the expert in another. For the beginner, novelty is anything that hasn't been encountered before. For the expert, novelty is nuance."

(Angela Duckworth)

"So I discovered early on if you want anything you went for it and you got it. And most people don't ever go anywhere or want anything, so they never get anything."

(Ray Bradbury)

"the physical universe has structure, and one’s perceptions of this structure, one’s partiality to some of its characteristics and aversion to others, are precisely the elements that make up one’s taste."

(Chen Ning Yang)

Genialität als ein Etwas, das uns in die Lage versetzt, Wert zu detektieren, und das uns danach streben lässt, Wert hervorzubringen.

In seinen lebendigsten Stunden findet der Mensch Erfüllung.

Aufgabe der Philosophie: Den Charakter dieser Welt einzufangen; in deutlichen und klaren Worten. Unter Miteinbezug innerer Erfahrung.

Dem Philosophierenden geht es darum, fundamentale Einsichten in den Charakter dieser Welt zu gewinnen.

Einen Menschen sehen, in voller Stärke, ganz und gar in seinem Element ...

Der Reiz mancher Gedanken erschöpft sich nicht. An manchen Gedanken können wir wieder und wieder und wieder Anteil nehmen.

Das tun, was in der eigenen Macht liegt. Der Rest ist Schicksal.

Menschen, die auch im Schmerz noch singen. Denen der Mut nie abhanden kommt.

Freiheit: Die Bestrebung, das "Ich muss" zu entfernen, und, als Ersatz, das "Ich will" zu kultivieren.

Es gibt Richtungsentscheidungen, im Leben, die zu einem Mehr an wertvollem Leben hinführen, oder von solchem Leben entschieden wegführen.

Die Welt ist in einer Weise beschaffen, dass wir in ihr zutiefst positive Erfahrungen sammeln können.
