Shades of pink and blue: Unidimensional spectra of identity within a multidimensional model of diversity.

There is currently no unifying theory providing a science-based rationale of shared origins for conventional and unconventional human identities. Contemporary notions of human identity increasingly challenge traditional binary concepts, yet, despite identity's subdivision into numerous sub-categories, there is debate on how to represent and interpret them. In contrast to classic bipolar theories, and following other recent models, this paper examines complex spectrum theory to include gender and other facets of identity aligned along separate minimalist spectra. It hopes to provide a scientifically grounded, yet simplistic contribution to visualizing the infinite expression of human identity diversity. The article presents multidimensional aspects of identity, including gender, as lying within a canalized range of variation The physiological linking of these spectra may assist in evaluating the shared origins of all human identity.
