Openness and Schizotypy:

"What Openness and positive schizotypy share is an elevated tendency to perceive patterns and meaning in loosely related stimuli. In positive schizotypy this tendency is taken to an extreme in which patterns may be identified as objectively real even when they are not (a phenomenon also known as “apophenia”). Intelligence may play a key role in determining whether identification of patterns by people high in Openness leads to adaptive cognitive abilities—such as creativity, which is strongly linked to Openness (DeYoung, 2015; Kaufman et al., 2016)— or to the apophenia that characterizes positive schizotypy."

"Broadly speaking, neurostructural and neurofunctional findings indicate that psychotic-spectrum diseases are linked to disrupted or aberrant patterns of neural connectivity. This body of evidence has led to the dysconnectivity theory of psychosis, which states that the core symptoms of psychosis are the result of altered connectivity between brain regions, particularly between specific thalamocortical and frontotemporal regions (Pettersson-Yeo, Allen, Benetti, McGuire, & Mechelli, 2011). Connectivity is typically observed as aberrantly low between these regions (hypoconnectivity), although some specific interconnections may be aberrantly high (hyperconnectivity; e.g., Filippi et al., 2014). Such altered connectivity patterns are thought to lead to abnormal sensory and cognitive integration (Pettersson-Yeo et al., 2011)."

The copy is the original

"T
he Chinese have two different concepts of a copy. Fangzhipin (仿製品) are imitations where the difference from the original is obvious. These are small models or copies that can be purchased in a museum shop, for example. The second concept for a copy is fuzhipin (複製品). They are exact reproductions of the original, which, for the Chinese, are of equal value to the original. It has absolutely no negative connotations."

"From the start, the production of replicas of the terracotta warriors proceeded in parallel with the excavations. A replica workshop was set up on the excavation site itself. But they were not producing ‘forgeries’. Rather, we might say that the Chinese were trying to restart production, as it were – production that from the beginning was not creation but already reproduction. Indeed, the originals themselves were manufactured through serial mass-production[.]"

"The Ise Grand Shrine, the supreme Shinto sanctuary located on Honshu island, is 1,300 years old for the millions of Japanese people who go there on pilgrimage every year. But in reality this temple complex is completely rebuilt from scratch every 20 years. This religious practice is so alien to Western art historians that, after heated debates, UNESCO removed this Shinto temple from the list of World Heritage sites. For the experts at UNESCO, the shrine is 20 years old at most."

"[The] difference between original and copy vanishes altogether. Instead of a difference between original and copy, there appears a difference between old and new. We could even say that the copy is more original than the original, or the copy is closer to the original than the original, for the older the building becomes, the further it is from its original state. A reproduction would restore it, as it were, to its ‘original state’, especially since it is not linked to a particular artist."

-----

"In the West, when monuments are restored, old traces are often particularly highlighted. Original elements are treated like relics. The Far East is not familiar with this cult of the original."

Festgelegtheit:

Sind bei einem bestimmten Prozess oder Experiment sämtliche Ausgänge gleichwahrscheinlich, dann gilt: je mehr Ausgänge möglich sind, umso weniger Festgelegtheit oder Determiniertheit besteht. Festgelegtheit in dem Sinne, in welchem Ausmaß wir, unter den uns bekannten Bedingungen, ein Einzelereignis vorhersagen können. Angenommen, wir wissen, eine perfekt symmetrische Münze, ein perfekt symmetrischer sechsseitiger Wüfel, und ein perfekt symmetrischer zwölfseitiger Würfel werden geworfen. Wir haben aber keinerlei Informationen darüber, unter welchen spezifischen Bedingungen, d.h. mit welchen Handbewegungen, usw., der Einzelwurf stattfinden wird. Diese Bedingungen, obwohl vorhanden, messen wir nicht und lassen wir nicht in unsere Berechnung einfließen. Somit, bei Unkenntnis der Einzelbedingungen, kommen den Ausgängen der Ereignisse Informationgehalte von 1 bit (log2(2)), 2.58 bit (log2(6)) und 3.58 bit (log2(12)) zu. D.h. unter den uns bekannten Bedingungen ist der Ausgang des einzelnen Wurfs mit dem zwölfseitigen Würfel weniger festgelegt als der Ausgang des einzelnen Wurfs mit dem sechsseitigen Würfel, und dieser Ausgang ist wiederum weniger festgelegt als der Ausgang eines einzelnen Münzwurfs. Je weniger festgelegt nun Prozesse sind, oder je weniger festgelegt wir Prozesse wahrnehmen, umso informationshaltiger und umso weniger vorhersagbar sind sie für uns. Umso größere Ungewissheit besteht darüber, wie sie ausgehen werden.
