About

Herzlich willkommen bei „Quarks Dimension Ralph", dem Kanal von Quarks, in dem Ralph Caspers euch an die Grenzen der Wissenschaft mitnimmt! Schön, dass ihr hier gelandet seid! Aber war das euer freier Wille? Oder ist das, was ihr als freien Willen wahrnehmt vielleicht nur eine Illusion? Bei „Quarks Dimension Ralph“ geht es um echt komplizierte Fragen – von den Rätseln unseres Gehirns bis zu den Geheimnissen des Universums. Uns, und hoffentlich euch auch, macht es Spaß, über solche Fragen nachzudenken. Wir recherchieren gründlich, erzählen, wie Wissenschaftler:innen mit verblüffenden Experimenten nach Antworten suchen und ordnen die Ergebnisse ein. Auch wenn es für viele Fragen keine eindeutige Antwort gibt, liefern unsere Videos jede Menge Erkenntnisse mit Mindblow-Garantie.

Video Description

Ob optische Täuschung, selektive Wahrnehmung oder künstliche Intelligenz – die Wahrheit ist oft weniger objektiv, als sie scheint. Doch kann es so überhaupt eine gemeinsame Realität geben? Nicht nur die Sinne täuschen uns – wie beim Hör-Experiment „Brainstorm oder Green Needle“. Auch Ziele und Überzeugungen beeinflussen, was wir wahrnehmen. Forscher nennen das „direktionales Motiv“. Konstruktivisten wie Jean Piaget betonen zudem, dass wir unsere Wirklichkeit aktiv erschaffen: auf der Basis von Erfahrungen, Emotionen und Erwartungen. In sozialen Interaktionen gleichen wir unser Weltbild, unser Wissen und unsere Realität dann mit anderen Menschen ab und schaffen so einen gemeinsamen Konsens von Wirklichkeit und Wahrheit – das ist dann „sozialer Konstruktivismus“. Ein prägnantes Beispiel ist der Klimawandel: Schon 1938 belegte Guy Callendar den menschengemachten Treibhauseffekt. Aber war dieser auch damals schon „wahr“? Oder brauchte es dafür erst die allgemeine Anerkennung durch die Wissenschaft und einer Mehrheit? Heute verzerrt auch künstliche Intelligenz unsere Wirklichkeit. Eine aktuelle Studie zeigt: KI übernimmt menschliche Wahrnehmungsverzerrungen nicht nur, sondern verstärkt sie sogar. Menschen passen ihre Einschätzungen oft an die Ergebnisse der KI an – es entsteht eine Rückkopplungsschleife. Welche Probleme das mit sich bringt und warum das so ist, erzählt euch Ralph im Video. *Kapitel* 0:00 Hör-Experiment: „Brainstorm“ oder „Green Needle“? 1:03 Wahrheit vs. Illusion: Unsere Sinne sind nicht objektiv 2:06 Direktionales Motiv: Ziele formen unsere Wahrnehmung 2:56 Sozialer Konstruktivismus: Piaget und Wygotski 4:05 Forschungsergebnisse: alles nur „ausgedacht“? 5:02 Klimawandel seit 1938: Ab wann ist etwas wahr? 5:41 Verzerrte Wirklichkeit durch Künstliche Intelligenz 7:22 Ist KI Teil unserer Realität? 8:11 Warum wir die Welt nicht objektiv wahrnehmen *✅ Linktipps* Was hörst du?
