On the size of sex differences in personality:

"When sex differences across multiple traits are combined using multivariate statistical methods, the global difference between the average profiles of men and women ranges between two and three standard deviations. This means that the personality distributions of males and females overlap by about 10%, which is close to the anatomical overlap between male and female faces (Del Giudice, 2013; Del Giudice et al., 2012). The comparison between faces and personality profiles is illuminating: while the sexes look fairly similar if one considers one anatomical feature at a time (e.g., the size of the eyes, the length of the nose), the difference becomes obvious as soon as one starts looking at whole faces of men and women."

'Flow':

Momente, Stunden und Tage, wo dem menschlichen Denken und Erleben vorübergehend nicht mehr die Erdenschwere anzuhaften scheint. Wo sich die Aufmerksamkeit entschieden auf pos. Möglichkeiten anstatt auf Gefahren, Notwendigkeiten und Problematiken richtet.

"The evolution of language—another defining adaptation of our species—permits the exchange and transmission of information on an unprecedented scale."

"an improper or outdated or otherwise invalid attachment—such as the attachment to an inappropriate pattern of behavior or belief—turns the world into waste"

Romantic Love and Sexual Desire as Separate Relational Processes

Romantic Love and Sexual Desire in Close Relationships
Gian C. Gonzaga et al. (2006)

"Two schools of thought converge on the notion that romantic love and sexual desire are independent relational processes. Relationship researchers have long grappled with the question of how romantic love and sexual desire emerge and evolve over the course of intimate relationships (Aron & Aron, 1998; Hatfield, 1988; Hatfield & Rapson, 1993; Hatfield & Walster, 1978; S. S. Hendrick & Hendrick, 1992; R. J. Sternberg, 1986). Within this tradition, researchers differentiate between companionate love (or romantic love, in our terminology), which involves deep feelings of commitment, intimacy, and connection, and passionate love (or sexual desire, in our terminology), which involves powerful feelings of attraction, desire, passion, and infatuation (Diamond, 2003; Hatfield, 1988; Hatfield & Rapson, 1993; Reis & Shaver, 1988). Within this framework, romantic love fulfills a commitment role, sustaining long-term bonds by promoting intimacy, connection, and the formation of mutual long-term plans (e.g., Aron & Aron, 1998; Diamond, 2003; Dion & Dion, 1973; Ellis & Malamuth, 2000; Hatfield & Rapson, 1993; S. S. Hendrick & Hendrick, 1992; R. J. Sternberg, 1986). In line with this thesis, romantic love relates to an interest in being close to a partner (Aron & Aron, 1998; Hatfield, 1988; Hatfield & Walster, 1978) and encourages self-disclosure (Aron, Norman, Aron, McKenna, & Heyman, 2000; S. S. Hendrick, Hendrick, & Adler, 1988; Wieselquist, Rusbult, Foster, & Agnew, 1999). Moreover, the feeling of falling in love involves a rapid expansion of the self to include the partner (Aron & Aron, 1997), and perceptions of increasing love across the duration of a relationship predict later relationship continuation (Sprecher, 1999).

In contrast, sexual desire—and related feelings of passion and infatuation—fulfill an initiation role, motivating sexual interest, proximity seeking, and initial contact. By motivating proximity seeking, sexual desire promotes contact and allows commitment to grow (e.g., Hazan & Zeifman, 1994, 1999; Zeifman & Hazan, 1997). In line with this thesis, passion— or sexual desire—tends to peak early in a relationship (Aron & Aron, 1991; Berscheid, 1985; Regan, 1998; R. J. Sternberg, 1986), and behaviors motivated by sexual desire, such as sexual contact or certain kinds of touch, are less frequent in more established relationships (Sprecher & Regan, 1998).

Evolutionary and attachment-related accounts of relationships have similar claims about romantic love and sexual desire (e.g., Diamond, 2003; Fisher, 1998; Hazan & Shaver, 1987). Romantic love is thought to be part of a pair-bonding system, which keeps partners together in long-term relationships that are oriented toward raising vulnerable, dependent offspring to the age of viability (Buss, 1988, 1994; Buss & Schmitt, 1993; Fisher, 1998; Kenrick & Trost, 1997; Simpson, 1994). As a part of the mating system and with the primary goal of reproduction, sexual desire responds to cues of reproductive readiness, such as physical markers of fertility or status (Buss, 1994).

This evolutionary, attachment-related approach is best encapsulated in Diamond’s (2003, 2004) biobehavioral model of romantic love and sexual desire. Diamond argued that romantic love and sexual desire serve different functions, namely to promote pair bonding and sexual behavior, respectively. In support of these claims, Diamond reviewed evidence showing that the subjective experiences of romantic love and sexual desire are functionally independent: Individuals can feel romantic love but not sexual desire, or sexual desire but not romantic love, toward another person. Romantic love and sexual desire, Diamond claimed, also appear to be mediated by different physiological processes: oxytocin (OT) and endogenous opioids in the case of romantic love, and gonadal estrogens and androgens in the case of sexual desire. ..."

Ordnung und Information:

Eine geordnete Umwelt ist weniger informationshaltig als eine chaotische Umwelt:

Wenn jemand in einer ordentlichen Wohnung sagt, dass sich die Butter im Kühlschrank befindet, so hat diese Aussage einen geringen Informationsgehalt. Wir nehmen ja bereits im vorhinein an, dass sie sich im Kühlschrank oder gegebenfalls auf dem Esstisch findet.

Wenn wir in eine restlos ungeordnete Wohnung gehen, d.h. in eine Wohnung, auf deren Fläche sämtliche Gegenstände restlos chaotisch verteilt sind, so ist die Nachricht, dass sich die Butter unter dem Sofa, der Kopfpolster in der Küche, und der Heftklammerapparat im Badezimmer finden, hochgradig informativ.

Im zweiten Fall können wir nicht effektiv im vorhinein urteilen, an welchen Stellen der Wohnung wir Gegenstände mit hoher Wahrscheinlichkeit antreffen.

"Das Prinzip, das wir weiterhin kurz Redundanzprinzip nennen wollen, besagt folgendes: Der Mensch (und wohl auch jeder andere wahrnehmungs- und lernfähige Organismus) ist bestrebt, die objektive Information der Außenwelt auf verschiedene Weise subjektiv zu verringern. ... Redundanzprozesse haben dabei den Sinn, dem Menschen (bzw. dem Organismus) die Außenwelt so informationsarm zu machen, dass eine Orientierung und ein geordnetes Verhalten darin möglich wird."
