Which aspect of Jungian psychology is generally considered controversial by modern psychologists?

The term "group unconscious" is not a widely recognized concept in Jungian psychology or mainstream psychological discourse. While Jung did discuss collective aspects of the unconscious, the specific term "group unconscious" is not a common or controversial concept within this framework.

The individual unconscious, as proposed by Jung, pertains to an individual's personal repository of repressed memories, desires, and experiences. This aspect of Jungian psychology is generally accepted and integrated into various psychological theories, making it less controversial compared to the concept of the collective unconscious.

The personal unconscious, similar to the individual unconscious, refers to an individual's unique unconscious mind containing personal experiences and memories. This concept aligns more closely with traditional psychological frameworks and is less contentious compared to the notion of a collective unconscious shared by all humanity.
