What is mental model/mindset? What forces influence the mental model/mindset, and what forces cause evolution of that mental model/mindset?
How has mental model/mindset limited the decision making? This is part of answer... It starts with one's parents or caregivers and other leading people in person's early life (that is; coaches, teachers, ministers etc.). These are most probable the major influencers. Also, being with the company for a short time (particularly one which has initiated training).
