Gender identity refers to an individual's internal understanding of their gender, which may correspond to or differ from their sex assigned at birth. The term was introduced by Robert Stoller and later promoted by John Money, and has since been examined from psychological, legal, and philosophical viewpoints.
Jared Polis defines it in a legal context, focusing on its societal impact, while Samuel Vaknin emphasizes its formation through social reinforcement and parental influence. Three Initiates view gender as a universal principle present in all phenomena. These various viewpoints together highlight gender identity as both a deeply personal experience and a construct influenced by cultural and social factors.
