Lewin's equation for behavior, ''B'' = ''ƒ''(''P'', ''E''), which means that behavior (B) is a function (f) of personal characteristics (P), and environmental characteristics (E).
Scholars in the 1930s reveled in fear that, by devoting themselves to applied research, they would distract the discipline from basic research on scholarly problems and create a false binary on whether research was developed for the perpetuation of their respective discipline or for practical application.

s at the time, Lewin argued that "applied research could be conducted with rigor and that one could test theoretical propositions in applied research."

, there was a method through which money could be acquired for research in a sustainable manner. Lewin has encouraged researchers to develop theories that can be used to address important social problems.
To demonstrate his dedication to applied research and to further prove that there was value in testing his theoretical propositions, Lewin became a "master at transposing an everyday problem into a psychological experiment".
Lewin, in his beginnings, took a seemingly banal moment between himself and a waiter and turned it into the beginnings of his field research, which Lewin reasoned that the "intention to carry out a specific task builds a psychological tension, which is released when the intended task is completed" in tandem with when

theorized that "wishes persist until they are satisfied."
This happenstance observation started the demonstration of the "existence of psychic tensions", fundamental to Lewin's
field theory.
While applied research helped develop Lewin into a practical theorist, what further defined him as an academic and a forerunner was his ''action research'', a term he invented himself.
Lewin was increasingly interested in the concepts of Jewish migration and identity. He was confused by the concept of how while an individual distanced themselves from performing the Jewish identity in terms of religious expression and performance, they were still considered Jewish in the eyes of
Nazis

. This concept of denying one's identity and the promotion of self-loathing as a form of coping with a dominant group's oppression represented the crisis of Lewin's own migration to the United States.
Lewin, as his student and colleague Ron Lippitt described, "had a deep sensitivity to social problems and a commitment to use his resources as a social scientist to do something about them.
In the early 1940s, he drew a triangle to represent the interdependence of research, training, and action in producing social change."
This diagramming of an academic's interests and actions within this triangulation yields an interesting part of accessing Lewin and his contributions. Rather than noting social justice as the beginning or the end, it was ingrained in every single academic action that Lewin took. It was this particular world view and paradigm that furthered his research and determined precisely how he was going to utilize the findings from his field research. Furthermore, it all reflected upon Lewin the man and his way of coping with the events of his time period. This devotion to action research was possibly a way of resolving a dissonance of his own passage to America and how he left his own back in present-day

gestaltism, understanding the totality and assessing a situation as a whole and not focusing only on individual aspects.

The approach, developed by Kurt Lewin, is a significant contribution to the fields of social science, psychology,

as a three-stage process. The first stage he called "unfreezing". It involved overcoming inertia and dismantling the existing "mind set". It must be part of surviving. Defense mechanisms have to be bypassed. In the second stage the change occurs. This is typically a period of confusion and transition. We are aware that the old ways are being challenged but we do not have a clear picture as to what we are replacing them with yet. The third and final stage he called "freezing". The new mindset is crystallizing and one's comfort level is returning to previous levels. This is often misquoted as "refreezing". Lewin's three-step process is regarded as a foundational model for making change in organizations. There is now evidence, however, that Lewin never developed such a model and that it took form after his death in 1947.

in 1946, Lewin received a phone call from the director of the Connecticut State Inter Racial Commission, which requested his help in finding an effective way to combat religious and racial prejudices. He set up a workshop to conduct a "change" experiment, which laid the foundations for what is now known as
sensitivity training.
[Lasch-Quinn, E. (2001) ''Race Experts: How Racial Etiquette, Sensitivity Training, and New Age Therapy Hijacked the Civil Rights Revolution'', New York, W. W. Norton.] In 1947, this led to the establishment of the

in their
environment.
The equation is the psychologist's most well known formula in social psychology, of which Lewin was a modern pioneer. When first presented in Lewin's book ''Principles of Topological Psychology'', published in 1936, it contradicted most popular theories in that it gave importance to a person's momentary situation in understanding his or her behavior, rather than relying entirely on the past.
Group dynamics
In a 1947 article, Lewin coined the term "
group dynamics
Group dynamics is a system of behaviors and psychological processes occurring within a social group (''intra''group dynamics), or between social groups ( ''inter''group dynamics). The study of group dynamics can be useful in understanding decision ...
". He described this notion as the way that groups and individuals act and react to changing circumstances. This field emerged as a concept dedicated to the advancement of knowledge regarding the nature of groups, their laws, establishment, development, and interactions with other groups, individuals and institutions. During the early years of research on group processes, many psychologists rejected the reality of group phenomena. Critics shared the opinion that groups did not exist as scientifically valid entities. It had been said by skeptics that the actions of groups were nothing more than those of its members considered separately. Lewin applied his interactionism formula, ''B'' = ''ƒ''(''P'', ''E''), to explain group phenomena, where a member's personal characteristics (''P'') interact with the environmental factors of the group, (''E'') its members, and the situation to elicit behaviour (''B''). Given his background in
Gestalt psychology
Gestalt psychology, gestaltism, or configurationism is a school of psychology and a theory of perception that emphasises the processing of entire patterns and configurations, and not merely individual components. It emerged in the early twent ...
, Lewin justified group existence using the dictum "The whole is greater than the sum of its parts". He theorized that when a group is established it becomes a unified system with supervening qualities that cannot be understood by evaluating members individually. This notion – that a group is composed of more than the sum of its individual members – quickly gained support from sociologists and psychologists who understood the significance of this emerging field. Many pioneers noted that the majority of group phenomena could be explained according to Lewin's equation and insight and opposing views were hushed. The study of group dynamics remains relevant in today's society where a vast number of professions (e.g., business and industry, clinical/counseling psychology, sports and recreation) rely on its mechanisms to thrive.
The most notable of Lewin's contributions was his development of group communication and group dynamics as major facets of the communication discipline. Lewin and his associated researchers shifted from the pre-existing trend of individualist psychology and then expanded their work to incorporate a macro lens where they focused on the "social psychology of small group communication" (Rogers 1994). Lewin is associated with "founding research and training in group dynamics and for establishing the participative management style in organizations".
He carved out this niche for himself from his various experiments. In his Berlin research, Lewin utilized "group discussions to advance his theory in research." In doing so, there was certainly the complication of not knowing exactly whom to attribute epiphanies to as an idea collectively came into fruition. In addition to group discussions, he became increasingly interested in group membership. He was curious as to how perspectives of an individual in relation to the group were solidified or weakened. He tried to come up with the way identity was constructed from standpoint and perspectives. These were the beginnings of what ended up developing into "groupthink". Lewin started to become quite interested in how ideas were created and then perpetuated by the mentality of a group. Not included in this chapter is how important this became in looking at group dynamics across disciplines – including studying John F Kennedy and the way he tried to interact with his advisors in order to prevent groupthink from occurring.

. Peaches tend to be soft and friendly on the surface, even with strangers, but have a hard protective inner core. Coconut cultures include China, Russia and most of Europe except the south. Folk from coconut cultures have a soft inner core, but a tough exterior than can lead to a perception of unfriendliness with strangers. Yet once a person has gained their trust, they can be loyal friends for life. The Peach v Coconut analogy was later popularised by
Fons Trompenaars, who said it "explains all sorts of animosities that bedevil cross-cultural friendships, business dealings and diplomacy."
