  Quantum-mechanical models of human cognition, opinion formation and
decision-making have changed the way we understand and predict human behaviour
in many practical situations, including political elections, financial
decisions and international affairs. Yet, at present, such models overlook
certain essential social aspects of human behaviour and self-identification. In
this paper, we introduce a magnetism-inspired quantum-mechanical model of
gender fluidity, a concept that challenges social norms across the globe.
Addressing a number of independent suggestions made by members of the general
public concerning a potential analogy between quantum superposition and
non-binary self-identification, we explore new territories, demonstrating that
physic of magnetism can help explain gender fluidity and similar social
phenomena better than the traditional quantum-mechanical models of human
cognition and perception. We anticipate that the proposed model can be used to
analyse experimental datasets aimed to develop sexual orientation and gender
identity legal definitions as well as to create artificial intelligence systems
that can sensibly identify both binary and non-binary genders.
