Outsider Art often includes works by which of the following groups?

Outsider Art is characterized by its creation by self-taught artists and individuals who operate outside the formal art world or established artistic conventions. This type of art often emerges from personal experiences, social conditions, or inner visions rather than academic training or professional ties to the art establishment. The artists associated with Outsider Art frequently have unique perspectives and produce work that reflects their individual journeys, free from the constraints of traditional artistic standards or commercial pressures.

This focus on self-taught artists and those marginalized by the traditional art community is what distinctly defines Outsider Art, contrasting it with works produced by those with formal training or significant recognition within mainstream art circles.
