What are the Causes of split personality?

Answer 1

The causes to a split personality are actually fairly easy to pinpoint. Even at a young age you are able to create a split personality due to severe trauma in ones life. The trauma would have to be continuous and most of the time it happens to someone rather shy. The mind, in a way to protect itself, would split and add on someone less timid and more bold and standoffish.

Answer 2

Split personality, also known as dissociative identity disorder, is believed to be caused by severe trauma, such as childhood abuse or neglect. The impact of trauma can lead an individual to dissociate as a coping mechanism, resulting in the development of different identities or personality states. Research also suggests that there may be a genetic or biological predisposition to developing dissociative symptoms.
