KYKO, an acronym for Know Yourself and Know Others, is a psychometric instrument to discover yourself and other personality profile. KYKO was designed and researched since 1976 by Mr. Bernard Ah Thau, Tan, based on the integration of the existing personality theories incorporating with the needs and deprivation theories to understand the intricate complexities of human behavior.

KYKO was designed based on the following premises:

• Human behavior is motivated by needs satisfaction and deprivation
• Human personality lies in the continuum of relatively static and dynamic
• Human personality lies in the continuum of normal and abnormal
• Human personality is unique, no two persons are alike
• Human personality is not constant. It varies with the experiences in the environment
• Human personality is developed from the genes and past experiences from the environment
• Future experiences continually shapes a person's personality

KYKO Personality Profile consists of five (5) dimensions as follows: -

• Self-Actualizing Self- The behavioral traits or quality of an individual that depicts the need for growth, progress, improvement, and fulfillment and to find meanings in life.
• Egocentric Self - The behavioral traits or quality of an individual that depicts the need for power, image and control.
• Sociocentric Self- The behavioral traits or quality of an individual that depicts the need for love, care, companionship and affiliation.
• Security Self - The behavioral traits or quality of an individual that depicts the need for security, order, systems and protection.
• Manipulative Self - The behavioral traits or quality of an individual that depicts the need to adapt and change for survival and growth.

Based on the five (5) dimensions, ten (10) personality types are identified.

• Egocentric Dimension - Aggressive Type Vs Submissive Type
• Sociocentric Dimension - Social Type Vs Asocial Type
• Security Dimension - Pragmatic Type Vs Adventurous Type
• Self-Actualizing Dimension - Normal Type Vs Neurotic Type
• Manipulative Dimension - Dynamic Type Vs Static Type

Each type is made up of a list of traits and characteristic both positive and negative.

The five (5) dimensions are organized in to spider web showing the relative strength of each dimension. The process of organizing the relative strength of each of the five dimensions is called "webbing" because the procedure creates a 'spider web' of the person's personality profile. Below is an example of a spider web of KYKO Personality Profile:

The shape of the spider web depicting the high, average and low of the ten (10) personality types is used to identify human traits and characteristics to explain human differences.
