Sad to see Carl Jung's name tainted in this article here because of his early association with Freud. They were two very different psychoanalysts. Jung split from Freud because of Freud's obsession with sex and insistence with filtering all human experience through that lens. He developed a more spiritual approach to psychology as well as the concepts of the collective unconscious distinguishing it from the personal unconscious of Freudian psychoanalysis. He argued that the collective unconscious had profound influence on the lives of individuals, who lived out its symbols and clothed them in meaning through their experiences.. There is a vast chasm between Freudian and Jungian psychotherapists and psychoanalysts which lasts to this day.

Here is a link with a very simple summary about the two men https://www.simplypsychology.org/psychodynamic.html

Jung's close collaboration with Freud lasted until 1913. Jung had become increasingly critical of Freud's exclusively sexual definition of libido and incest. The publication of Jung's Wandlungen und Symbole der Libido (known in English as The Psychology of the Unconscious) led to a final break.

From Wikipedia :

Critics of the collective unconscious concept

They mean Freudians

have called it unscientific and fatalistic, or otherwise very difficult to test scientifically (due to the mythical aspect of the collective unconscious) for those faith-based scientists.[2] Proponents suggest that it is borne out by findings of psychology, neuroscience, and anthropology.

Meaning: can no longer hide the fact that neuroscience and other scientific disciplines are corroborating Jung's theories.

The world of psychology is still largely dominated by Freudian disciples. Please don't get the two men and their work confused. It would be a huge disservice to Jung.
