a psychological concept that describes three fundamental prosocial personality traits: humanism, belief in humanity and Kantianism (from the surname of I. Kant). Introduced by a psychologist and a team of authors consisting of S. B. Kaufman, D. B. Yaden, E. Hyde, E. Tsukayama in 2019 as the antithesis of the Dark Triad, this model is a system of positive characteristics that contribute to harmonious social relations and personal growth. Belief in humanity is the belief that people are basically good; humanism – the conviction that people deserve respect and recognition; Kantianism is an attitude towards a person as an intrinsic value, an end in itself, and not as a means to achieve goals. It has been established that people with a predominance of Light personality traits are characterized by the ability to partner with others, trust in other people, a high level of life satisfaction, and positive self-esteem.
