After decades of scientific research on personality in the context of human psychological development, Dr. Roland Kim has uncovered the secret behind a typical relationship attraction and conflict.

The personality theory he developed found that personality is primarily the product of the environment, though some genes may explain minor areas through traits, such as introversion and extraversion, as claimed by Carl Jung and Phillip Zimbardo. 

The theory here clarifies the myth of personality by identifying one’s personality type and characteristic features to find more accurate classifications and suggestions for future conflict resolution.

The planet personality quiz is based on the 5 personality types defined by Roland Kim, Ph.D. According to Dr. Kim, we are each swing between the degree of independence from the family or group (collectivism-individualism dimension) and the level of compassion (femininity-masculinity dimension), and these 2 axes are the building blocks of his personality theory.

The test has been developed through Dr. Kim’s decades of theoretical and scientific research in psychology, psychoanalysis, and culture, based both on the empirical research data as well as many theories on human development and personality from Sigmund Freud, Carl Jung, Melanie Klein, Erik Erikson, Margaret Mahler (especially Object Relations Theory), Abraham Maslow, and many other scholars.

Dr. Kim has attempted to integrate various psychoanalytic and psychological theories to find the universal emotional and socio-cultural development theory. His theory may fill the gap in the theories of human development introduced by Ken Wilber’s Integral Theory and Clare Graves’s Spiral Dynamics that have been criticized for lacking mainstream academic support due to the absence of academic rigor for the complexity of the model, narrow confinement in spiritual or business orientation. Realizing its astonishing similarity to Beck and Cowan’s (1996) spiral color spectrum of management leadership, Dr. Kim tried to use the similar coloring system to denote each personality of the model to match for Mercury with the colors of beige, purple, red, and blue, Mars with orange, Venus with green, Earth with yellow and Jupiter with Turquoise following the Beck and Cowan’s system.
