The logic for grounding POS in the eudemonic assumption was based on the
heliotropic effect (Cooperrider, 1991). Heliotropism is defined as the tendency of living systems to seek that which is life-giving and to avoid that which is life-depleting. This
effect is shown when organisms move away from darkness toward light or positive
energy (e.g., a plant bending toward the sun). Evidence that living systems have an
inherent inclination toward positive energy and disinclination toward negative energy
has been observed in a variety of disciplines, including the social and biological
sciences.
