Human intelligence Genius (plural geniuses) is something or someone embodying exceptional intellectual ability, creativity, or originality, typically to a degree that is associated with the achievement of unprecedented insight.
There is no scientifically precise definition of genius, and indeed the question of whether the notion itself has any real meaning is a subject of current debate. The term is used in various ways: to refer to a particular aspect of an individual, or the individual in their entirety; to a scholar in many subjects (e.g. Isaac Newton or Leonardo da Vinci) or a scholar in a single subject (e.g. Albert Einstein or Stephen Hawking). Research into what causes genius and mastery is still in its early stages, but psychology already offers relevant insights.
