Risk-taking as a situationally sensitive male mating strategy

Risk-taking as a situationally sensitive male mating strategy
Michael K Baker and John K Maner; 2008

Abstract

Evolutionary theorists suggest that men engage in risk-taking more than women do in part because, throughout human evolutionary history, men have faced greater sexual selection pressures. We build on this idea by testing the hypothesis that risk-taking reflects a male mating strategy that is sensitive to characteristics of a potential mate. Consistent with this hypothesis, the current experiment demonstrated a positive relationship between mating motivation and risk-taking, but only in men who had been exposed to images of highly attractive females. Moreover, risk-taking in men was associated with enhanced memory for attractive female faces, indicating enhanced processing of their attractive facial characteristics. No relationship between mating motivation and risk-taking was observed in men exposed to images of unattractive women, nor was any such relationship observed in women. This experiment provides evidence that psychological states associated with mating may promote risk-taking, and that these effects are sex specific and are sensitive to situational context.

"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."

"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.
