The STAR mindsets are the translation layer between the complexity of behavioural science and the reality of working with people every day. Each mindset is anchored in Self-Determination Theory, shaped by the Big Five personality traits, and filtered through cognitive, regulatory, and emotional lenses.
Most people carry a strong primary orientation and a meaningful secondary one. It is the combination of those two that creates one of the twelve STAR archetypes — the level at which individual identity truly reveals itself.
Deep-dive into each type →"The STAR mindsets are not boxes to put people in. They are lenses to see people through."

A
Adventurer
Autonomy · Promotion · System 1
