Making Vocational Choices: A Theory of Vocational Personalities and Work Environments

Proposes six vocational personality types (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) and argues that congruence between person-type and environment-type predicts satisfaction, stability, and achievement.

Holland's RIASEC model is the most widely used person-environment fit typology. It establishes that categorical engagement modes exist and that congruence matters — the same structural logic MN uses, with critical philosophical differences.

MN's nine natures parallel Holland's logic of distinct engagement modes but differ in key ways: Holland's types are identity-based ('you ARE artistic'), while MN natures are energy-based ('this is what energizes you'). MN also refuses to reduce engagement to six categories, including modes Holland excludes (Protective, Healing, Adventurous).

Holland's model IS a trait/type system — exactly what MN critiques. The parallel is structural (both propose categorical modes) but philosophically opposed (traits vs energies).
