History behind the term 'Split Personality'


The Introduction of 'Double Consciousness'

In 1886, Robert Louis Stevenson published his famous novel 'The Strange Case of Dr. Jekyll and Mr. Hyde.' The story follows the character of Dr. Jekyll, a well-respected scientist who creates a potion that transforms him into the evil Mr. Hyde. This duality of a single character having two distinct personalities became popularly known as 'double consciousness' and laid the foundation for the idea of a split personality.


Freud's Contribution and the Term 'Split Personality'

Sigmund Freud, the renowned psychoanalyst, further explored the concept of multiple personalities in his work. In 1906, he introduced the term 'Split Personality' in his book 'Die Traumdeutung' (The Interpretation of Dreams). Freud's theories and clinical observations became influential in shaping the understanding and recognition of individuals with dissociative identity disorder, the clinical term for a split personality.


Popularization in Pop Culture

During the 1950s, the concept of a split personality gained significant attention in popular culture. Films like Alfred Hitchcock's 'Psycho' (1960) and 'The Three Faces of Eve' (1957) brought the idea of dual or multiple personalities to mainstream audiences, sparking curiosity and fascination.


Diagnostic Recognition

In the 1970s, the Diagnostic and Statistical Manual of Mental Disorders, commonly referred to as DSM, began to formally recognize and provide diagnostic criteria for dissociative identity disorder (DID), synonymous with a split personality. This recognition helped legitimize the condition in the field of psychiatry and mental health.


Continued Understanding and Treatment

Today, the concept of a split personality is widely recognized as a rare but legitimate mental health condition. Current understanding suggests that dissociative identity disorder arises from severe trauma and serves as a coping mechanism. Mental health professionals work with individuals diagnosed with DID to help them integrate their various identities and facilitate healing.

Did you know?

Did you know? The term 'split personality' is often mistakenly used as a synonym for Dissociative Identity Disorder (DID), a mental health disorder characterized by the presence of two or more distinct personality states. While they share common traits, they are not identical. So, National Split Personality day isn't really about DID, rather every fun contradiction that resides in us.
