Kurt Lewin’s Behavioral Theory from the 1940’s can be summarized as B = f(P, E). This means that Behavior is a function (f) of:
1) the person (P) (i.e., their internal traits, history) and
2) their environment (E) (i.e., physical, social, and psychological)
This means unsafe acts should NOT be blamed solely on the individual; they are highly influenced by environmental and psychological factors. His framework for understanding behaviors in relation to safety relies on two (2) core theories that explain how individuals and groups interact in dangerous or high-risk situations.
